Companion publications: The Compass–NWMLS Settlement Changed the Private Governor After Washington Changed the Governing Law | Zillow vs. Redfin–Compass, Premarket Control Under Expanding Transparency Laws | Two NWMLS Records, One Foster-Skillman Team — Primary-Source Evidence of the Compass Two-Gate Capture Model Inside the Washington Statutory Transition Window
Thesis in One Sentence
The Compass–NWMLS settlement did not bring back private listings: every broker now sees every First Look property while sellers and brokerages still shape what consumers see and whom buyers contact first, and MindCast’s simulation expects weaker double-ended commission capture overall with the surviving advantage concentrated on buyers who arrive without an agent.
Why This Paper, Why Now
The industry is still arguing about what the August 31 settlement between Compass, Inc. and the Northwest Multiple Listing Service (NWMLS) actually did, and the argument keeps returning to a binary that obscures the change. The Compass–NWMLS Settlement Changed the Private Governor After Washington Changed the Governing Law resolved the legal layer: Washington’s Substitute Senate Bill (SSB) 6091 relocated the binding open-market constraint into public licensing law before the parties signed. The economic layer stayed open. Trade coverage already treats First Look as a candidate template for peer Multiple Listing Services (MLSs), which raises the stakes on answering the economic question before the template spreads.
We write now because timing converts the answer from commentary into a testable claim. First Look listings begin accumulating September 4, listing-broker attribution rules follow October 15, and expanded broker-platform data follows November 15. A paper published before the data states falsifiable expectations the data will grade. A paper published after the data merely narrates, and MindCast already holds the prediction the data will test.
The paper addresses six audiences. The Washington Department of Licensing (DOL) and state attorneys general inherit the dominant enforcement seam. MLS boards weighing the template need to know which design choices carry routing consequences. Brokerage counsel configuring Internet Data Exchange (IDX) policy need the observable that interpretation will read. Investors need to know what the settlement tests about the routing premium. Researchers and consumer advocates gain an unusually clean empirical design, and the trade audience gets the resolution the victory debate lacks.
Executive Summary
The settlement did not settle the commission question. It changed what any answer must be measured against. Washington now separates three functions the private-listing debate has treated as one: broker access, consumer discoverability, and buyer interaction. Under the old Private Exclusive architecture one brokerage could influence all three at once. First Look largely equalizes the first layer and leaves configurable variation in the second and third. Every First Look property enters NWMLS and reaches all 30,000-plus member brokers on entry. The separation creates a mechanism-isolation experiment: Washington removed routine exclusive access while leaving discovery and interaction independently configurable, so the market itself will now show whether inventory exclusion was the causal engine of commission consolidation or one implementation of a deeper buyer-routing architecture.
The paper’s claims sit in a strict hierarchy. Established: SSB 6091 eliminated routine brokerage-exclusive marketing as a lawful phased strategy in Washington, and mandatory submission ended exclusive inventory inside the cooperative while a set of attention-routing variables survived the settlement. The statute retains a narrow health-or-safety exception, and its constraint runs to the general public and all other brokers while First Look’s access guarantee runs across the cooperative. Surviving variables include a 21-day protected pre-launch window and suppression of public days on market (DOM) and price history, plus a seller-elected IDX opt-out and listing-broker attribution beside contact and tour functions from October 15. Hypothesis: those variables may preserve some portion of the commission-consolidation economics. Empirical question: how much, among whom, and under which First Look configuration.
The MindCast AI Proprietary Cognitive Digital Twin Foresight Simulation (MP CDT FS) has now resolved the competing hypotheses into predictions with stated bands and windows and falsifiers, so the paper answers by register rather than assertion. Nor does the paper attribute intent: the run tests whether consolidation emerges from First Look use rather than assuming Compass adopted the status to preserve it.
MindCast did not infer the migration from the settlement. It predicted the migration before First Look existed. Zillow vs. Redfin–Compass, Premarket Control Under Expanding Transparency Laws argued in March that transparency law removes the advantage obtainable from withholding listings and pushes competitive advantage toward buyer interaction and lead routing and platform control. Beneath it sit the February commission-consolidation model and the April Two-Gate transaction specimens, and beneath both sits the Dual Nash-Stigler mechanism explaining why a system holds an incentive to reroute through surviving gates when one gate fails. First Look supplies the first Washington institutional environment in which the March prediction can resolve after exclusive access has been removed. Two graded hits and the interaction-layer concessions Compass obtained already anchor the lineage before any listing data exists.
One counterintuitive implication anchors the falsification design. First Look could simultaneously reduce exclusion-driven double-ending and increase direct listing-side inquiry, without contradiction, because the two effects operate on different layers. A segmented outcome is live: attention routing may matter substantially for unrepresented buyers while NWMLS-wide broker access insulates represented ones. The natural experiment distinguishes the outcomes across three populations: First Look IDX-in inventory and First Look IDX-out inventory and ordinary Active listings. Interaction observables may require nonpublic sources, so the design separates transaction-level from interaction-level evidence. First-contact representation status is the pivotal observable, because the segmented hypothesis turns on the unrepresented buyer.
The behavioral layer carries an armed Skillman Moment precursor. The Skillman Moment names a controlled-forum claim that fails when an adversarial forum imports it, and the First Look version is layer substitution: Reffkin’s “fully realized” and “absolute right” statements answer routing questions with an access-layer fact. Section VIII logs the boundary and no specimen has completed.
The simulation expects the old economics to weaken rather than survive. Same-brokerage and dual-side capture declines from the pre-6091 architecture at 68-74%, the strongest-supported result in the register. Segmented substitution stands as the most likely successor at 62-68%, ahead of broad substitution and inventory dominance in that order. The decline runs smallest where downstream routing stays strongest at 58-64%, which is the signature separating segmentation from both alternatives.
Two nearer-term forecasts follow at candidate strength. Compass concentrates IDX-out on First Look inventory above peers at 60-65% by December 31, and October 15 attribution produces its own interaction-layer effect at 62-70% with the latter dependent on data that may not be public. The two inherited forecasts from earlier papers stand unchanged at their original bands, and Section XI prints the full register with windows and falsifiers.
🏛️ Policymakers: Washington separated access from discovery and interaction, and the separation is the exportable design. Copy the guardrails and not only the status.
⚖️ Counsel: immediate NWMLS-wide access weakens theories built on broker exclusion and leaves standing the questions of consumer presentation and steering, plus agency formation and statutory public-marketing interpretation. Analyze the surviving questions on their own terms rather than importing them from the old architecture.
💼 Executives: the commercial contest migrates toward interface design and attribution, then inquiry routing and conversion, rather than possession of hidden inventory.
📊 Investors: the premium question is now a conversion question. Price the conversion advantage rather than an exclusivity premium Washington no longer permits.
🔬 Researchers and consumer advocates: the regime creates a clean design. The represented-versus-unrepresented distinction is the critical axis, because NWMLS-wide access may protect the former far more effectively than the latter.
The paper proceeds in fourteen sections plus annotated sources. Sections I through IV state the question, the old architecture, and what Washington killed and kept. Sections V through VII carry the three-layer model, the prediction lineage, and the competing hypotheses. Sections VIII through XI cover consequences and the natural experiment, then stakeholders and the MindCast Simulation Predictions. Section XII converts each prediction into exposure and mitigation, Section XIII names what to watch, and Section XIV concludes.
I. The Open Question: Did Commission Consolidation Survive the Settlement?
Coverage of the August 31 agreement scored a winner within hours and both parties supplied the scorecard. Compass chief executive Robert Reffkin called the objective fully realized and NWMLS chief executive Justin Haag said First Look protects buyers from private networks, and each described the layer he kept. The Compass–NWMLS Settlement Changed the Private Governor After Washington Changed the Governing Law resolved the legal layer: the binding open-market constraint moved into licensing law on June 11 and no private agreement can amend it.
The economic layer stayed open. The Law and Behavioral Economics of Compass vs. NWMLS modeled the institutional control layers five months before resolution and The MindCast MLS Equilibrium Series supplied the cooperative-transparency frame, and neither settles the question readers keep asking: did commission consolidation survive the death of exclusive access? The question governs everything that follows, and the answer takes the form of a migrated funnel testable within weeks.
📊 Investors: both victory statements are accurate and incomplete. Price the layer each party kept rather than the headline.
II. How Compass Captured Both Sides: The Two-Gate Model of Inventory Control
The Two-Gate Capture Model organizes the old architecture. Gate 1 intake suppression restricted early visibility and forced buyers through the listing side, and Gate 2 closing capture internalized both commissions through team-structured dual representation. The Compass Commission Consolidation Strategy and Real Estate Marketing Transparency built the economic model from thirteen months of Seattle ultra-luxury data and The Compass-Anywhere Address Suppression Calculus moved it to the transaction level three days later.
Two NWMLS Records, One Foster-Skillman Team — Primary-Source Evidence of the Compass Two-Gate Capture Model Inside the Washington Statutory Transition Window supplied the primary-source record: the $65 million Triptych listing where contact with one team gated basic information, and the Yarrow Point sale where one credential appeared on both sides. The record serves as specimen rather than allegation, because dual representation does not by itself establish unlawful conduct. Compass Double-Sided Commissions — Consumer Policy Center Measures the Output, MindCast Models the System added the external benchmark that separates measurement from characterization.
One structural claim carries forward as an incentive rather than a guarantee. The Dual Nash-Stigler Equilibrium Architecture predicts that a constrained system redirects capture effort toward surviving downstream gates when an upstream gate closes. Whether that substitution occurs, and how effectively, remains the empirical question the rest of the paper pursues.
⚖️ Counsel: the Two-Gate record is specimen rather than allegation. Dual representation alone establishes nothing unlawful and the register grades conduct rather than intent.
III. What Washington Killed: The Exclusive Information Window
Washington’s architecture severs the strongest causal link in the old model: inventory withholding from competing brokers. Every First Look property enters NWMLS on submission and reaches every member broker, so an outside buyer’s broker no longer routes through Compass to reach the property. The break is structural rather than cosmetic.
SSB 6091 supplies the statutory layer above the cooperative one. The statute requires concurrent marketing to the general public and all other brokers, and the Department of Licensing supplies disciplinary enforcement with a narrow health-or-safety exception. Compass Plan B, Structural Circumvention After Washington SSB 6091 predicted the adaptation posture in March before the statute was signed, and The Compass Collapse: A Post Washington SSB 6091 Passage Reckoning mapped the circumvention surfaces within two weeks of passage.
NWMLS’s counterclaim tied the old Private Phases to dual-side opportunity and full-commission capture, and the settlement removes the exclusive information window the counterclaim described. Compass v. NWMLS — The Counterclaim That Closed Compass’s Antitrust Thesis closed that analytical loop in April. The settlement paper then recorded the kill as statutory as well as contractual, because a private-only phase stays barred under any label.
🏛️ Policymakers: the kill is statutory as well as contractual. A private settlement cannot restore what licensing law removed.
IV. What First Look Preserved: Prelaunch Time, Hidden History, IDX Choice, and Attribution
Destroying exclusivity did not erase every commercially relevant variable. Four survivors deserve separate treatment rather than a collective relabel as private listing. Prelaunch time runs up to 21 days before Active status. Public information treatment keeps First Look time and preliminary price adjustments internally recorded while excluding them from public DOM and price-history display.
IDX choice lets sellers decline distribution during the period, and the October 15 attribution rules place the listing broker beside every contact and tour button. The four variables share one property: each operates on presentation and attention rather than on access. Compass v. NWMLS — The Counterclaim That Closed Compass’s Antitrust Thesis recorded the negative-insights history that makes the DOM treatment commercially meaningful.
Two refinements govern the treatment. October 15 counts as a discrete second intervention rather than another settlement term, because attribution can change interaction behavior apart from First Look status. And an IDX-in configuration does not forfeit the contest: prelaunch timing and history treatment and interface effects still operate on the interaction layer even when discovery stays at parity. The analytical standard comes from Compass’s Interpretation of “Public Marketing” May Draw Antitrust Scrutiny from State Attorneys General: display is not marketing to the general public on equal terms.
💼 Executives: price the private phase at zero and evaluate the four surviving attention assets separately.
V. Three Layers of the New Market: Broker Access, Consumer Discovery, Buyer Interaction
A marketplace decomposes into access and discovery and interaction, and the three layers can move independently. The decomposition is the paper’s conceptual contribution. Layer 1 asks whether competing brokers can obtain the inventory and information needed to represent clients. First Look largely answers yes.
Layer 2 asks which consumers encounter the property and through which public channels. The answer varies with IDX treatment, and Platform-Mediated Price Discovery — A Runtime Measurement Framework for the Compass–Redfin–Rocket Architecture built the measurement architecture for exactly that variation at the platform tier. Layer 3 asks which actor receives the inquiry and the tour request and the first relationship opportunity, and the answer is competitive and architecture-dependent.
The decomposition prevents one misreading and orders one chain. Attention control is not a monolithic power a brokerage simply retained: a marketplace can achieve universal cooperative access while keeping asymmetry in the two downstream layers. The discovery configuration conditions the contest and relationship formation resolves it, because a routed inquiry only matters when an unrepresented consumer becomes a listing-side relationship.
The Compass-Redfin Alliance — Market Self-Correction Is Dead showed broad consumer visibility coexisting with controlled inquiry routing in February, and Compass’s Coasean Coordination Problem Part IV — Platform Routing, Portal Power, and the Zillow Litigation drew the aggregation-versus-routing distinction in December of 2025. Rival brokerages hold the countermove: full-exposure marketing pitched against withheld discovery makes the seller’s configuration choice itself a competitive contest.
🔬 Researchers: the three layers are conceptually separable in data: Layer 1 is a submission record, Layer 2 an IDX flag, and Layer 3 requires first-contact evidence that may not be public.
VI. MindCast Predicted the Migration from Inventory Control to Buyer Attention in March
The claim here is resolution rather than novelty, and the chronology carries it. Compass’s Coasean Coordination Problem Part II — Litigation-Acquisition Monopolization Strategy forecast alternative routing infrastructure in December of 2025 as MLS constraints tightened. The Compass Commission Consolidation Strategy and Real Estate Marketing Transparencyidentified the economic value of inventory routing in February and The Compass-Anywhere Address Suppression Calculus moved the mechanism to the transaction level.
The Compass-Redfin Alliance — Market Self-Correction Is Dead then demonstrated that consumer visibility and inquiry control coexist, and Platform-Mediated Price Discovery — A Runtime Measurement Framework for the Compass–Redfin–Rocket Architecture built the runtime measurement layer on March 3. The decisive statement arrived March 18: Zillow vs. Redfin–Compass, Premarket Control Under Expanding Transparency Laws predicted that transparency regulation moves competition from control of listings toward control of buyer interaction. April added the double-sided commission benchmark and the Foster-Skillman transaction record as evidence, June removed routine brokerage-exclusive phased marketing as the lawful Washington baseline, and September institutionalized NWMLS-wide access while preserving the downstream variables.
The resolution claim states plainly: First Look did not generate the buyer-interaction thesis. It creates the first Washington institutional environment in which the March prediction can resolve after brokerage-exclusive inventory has been removed. The record on the underlying contest runs both ways: the settlement paper prints an 80-90% no-settlement miss beside its P50 to P70 architecture hit, and the grading discipline here is the same.
Graded record and corroboration. Compass’s Coasean Coordination Problem Part II — Litigation-Acquisition Monopolization Strategy forecast portal-partnership opacity strategies in December of 2025 and graded as a hit when the Redfin alliance landed in February. The March 23 architecture forecast resolved inside its published band on August 31, as graded in the settlement paper. The settlement terms then corroborate the migration independently, and the sharpest corroboration is behavioral: the concessions Compass obtained were attribution prominence and IDX choice and history treatment and data access, and none restored inventory exclusivity. The negotiation record shows the contest moving exactly where the March prediction said it would, and the launch-day release already carries the seller-protection grammar Section VIII dates.
📊 Investors: MindCast called the migration in March and prints its misses beside its hits. Weigh both when pricing the register below.
VII. Can Buyer Attention Replace Exclusive Inventory? Three Hypotheses and the Simulation Result
Three competing hypotheses structure the test, each with stated observables, and none is assumed. First-contact representation status is the pivotal observable throughout, because the segmented hypothesis resolves at the unrepresented buyer or not at all.
H0, inventory dominance. Once competing brokers receive immediate access the old economics largely collapse regardless of configuration scale. Attribution and prelaunch presentation and IDX choices prove insufficient substitutes for true exclusivity. Uniform sharp decline across every configuration resolves the register toward H0.
H1, broad attention substitution. Discovery and interaction advantages preserve material internalization across buyer populations, including buyers who already hold independent representation. Broad persistence across representation status resolves toward H1.
H2, segmented substitution. Attention routing substitutes effectively among previously unrepresented buyers while NWMLS-wide access insulates represented ones. A segmented equilibrium would reframe consumer-protection priorities around the unrepresented buyer specifically, and Compass Double-Sided Commissions — Consumer Policy Center Measures the Output, MindCast Models the System supplies the measurement baseline the outcome grades against.
The formal run resolves the slate. Segmented substitution leads at 62-68%, with broad substitution second and inventory dominance third. The ranking is more certain than the exact probability, and the falsifiers in Section XI let the market grade both.
⚖️ Counsel: the hypotheses are falsifiable in stated data. Build the record that grades them before an enforcer builds it for you.
VIII. The Next Legal Fight: Consumer Protection, Steering, and the Skillman Boundary
The legal exposure relocates with the mechanism, as a change in the dominant enforcement seam rather than a complete jurisdictional relocation. Inventory exclusivity drew antitrust and MLS-access theories, the terrain of the resolved federal case. Attention routing draws consumer-protection and steering theories, and Compass’s Interpretation of “Public Marketing” May Draw Antitrust Scrutiny from State Attorneys General mapped that seam on the day the statute took effect.
State licensing and consumer-protection authorities hold direct enforcement tools across the migrated surface, and competition law can still overlap where routing conduct meets market power. Why Compass Needs Private Listings, The Inventory-Routing Premium — Compass, the Anywhere Merger, and the Multi-State Enforcement Window built the multistate natural-experiment design in June, and the design now gains a comparison cell inside one statute state: IDX-in against IDX-out First Look inventory. One structural condition attaches: the settlement’s investigation limitation may increase dependence on public enforcement and make DOL latency strategically consequential, and nothing public establishes that NWMLS surrendered referral capacity. Latency also substitutes across jurisdictions: a passive Washington enforcer beside accumulating IDX-out volume makes an out-of-state attorney general the likelier first mover.
The messaging precursor is dated now because the statements it anticipates begin now. Public DOM suppression hands Compass a seller-protection justification the Private Exclusives never had, and seller-protection grammar in controlled forums is the dated qualitative expectation. Any such statement stands as a precursor only, and completion requires an adversarial forum importing it and exposing the mismatch. Compass Goes Quiet When It’s Questioned, Loud When It Isn’t — and the Loud Parts Keep Ending Up in Evidence supplies the mechanism and Senator Warren Just Asked Compass the Questions Its “Seller Choice” Answer Can’t Survive supplies the likeliest import channel.
The First Look Skillman Boundary. The Skillman Moment names a boundary failure: a claim that works inside one governing frame gets exported into a forum whose governing question it cannot answer, and the moment completes only when an adversarial forum imports the claim and exposes the mismatch. The three-layer model supplies this paper’s version of the boundary. Universal broker access is true at Layer 1, and the failure occurs when that Layer 1 truth is offered to answer a Layer 2 or Layer 3 question.
The grammar is already live. Compass’s settlement release moves from cooperative access to consumer protection in one step, and the sequence of “fully compliant” in June and “fully realized” in August now extends to Reffkin’s asserted “absolute right” of homeowners to control how their properties are marketed, a phrase the statute’s own text conditions. Layer 1 compliance does not answer a Layer 2 or Layer 3 incidence question: broker accessibility says nothing about whether consumers discover an IDX-out listing through ordinary channels or whether contact architecture routes an unrepresented buyer toward the listing side.
A completed specimen has a defined shape: an access-layer openness claim placed by DOL or an attorney general or a congressional questioner beside evidence that IDX-out reduced consumer discoverability or that unrepresented buyers disproportionately entered through listing-side contact, with the forum asking why broker accessibility answers a consumer-routing question. No specimen has completed. The statements identified here remain controlled-forum statements, and the boundary is logged as an armed precursor with the import vectors named: the Warren correspondence and the House Judiciary track and any DOL inquiry that quotes the release back.
⚖️ Counsel: the seam moved and the boundary is layer substitution. An access-layer answer to a routing question is the statement an adversarial forum will import.
IX. First Look as a Natural Experiment: How to Measure What Survived
The empirical design separates what can actually be observed. The study population separates First Look IDX-in inventory and First Look IDX-out inventory and ordinary Active listings. The design treats October 15 as a second intervention date, so attribution effects separate from First Look effects in the before-and-after structure.
Tier 1 covers transaction observables plausibly available at first pass: First Look status and duration, IDX status where the field is available, then brokerage identity with same-brokerage and same-agent outcomes. Tier 1 also carries listing dates and transaction outcomes and property characteristics, plus internal-versus-public history where NWMLS data access permits. The cumulative-DOM against displayed-DOM delta from Compass’s Interpretation of “Public Marketing” May Draw Antitrust Scrutiny from State Attorneys General remains the standing per-listing record of pre-public marketing duration.
Tier 2 covers interaction observables: first inquiry source, representation status at first contact, and conversion from unrepresented inquiry to listing-side or affiliated representation. Tier 2 may require portal data or brokerage records or discovery. Without interaction data, segmentation stays testable indirectly through transaction outcomes while first-contact causation stays unresolved, and the paper says so in advance.
The decisive comparison isolates consumer discoverability without reintroducing broker exclusion: does IDX-out First Look materially increase listing-side buyer acquisition relative to IDX-in First Look after controlling for property characteristics? One caution governs the whole design. IDX-out is seller-selected rather than randomized, so raw comparisons cannot establish causation and the eventual design should contemplate matching or fixed effects. Compass Double-Sided Commissions — Consumer Policy Center Measures the Output, MindCast Models the System and Two NWMLS Records, One Foster-Skillman Team — Primary-Source Evidence of the Compass Two-Gate Capture Model Inside the Washington Statutory Transition Window supply the baselines the comparison grades against.
🔬 Researchers: IDX-out is seller-selected rather than randomized. Matching or fixed effects is the difference between evidence and anecdote.
X. Stakeholder Implications
The model converts into audience-specific consequences, one audience at a time.
Policymakers and DOL. Analytical priority migrates from whether First Look exists toward how public marketing operates inside particular configurations. Compass’s Interpretation of “Public Marketing” May Draw Antitrust Scrutiny from State Attorneys General states the analytical standard the configurations will be tested against.
State legislatures. The settlement hands both camps their best exhibit: transparency advocates hold the 141-to-1 Washington record and a cooperative that absorbed phased marketing without breaking, while industry holds First Look as proof the market solved it. Timing decides which exhibit wins, because a mandate bill heard after a template lands opens against an installed norm. Template diffusion into non-statute states also inverts Washington’s sequence, delivering DOM suppression first with no statutory floor beneath it. Next-generation bills can close the seam Washington left open by defining concurrent marketing at the portal-display level and by addressing the steering of unrepresented consumers directly, and Governor Hochul’s pending consent-model decision in New York is the live fork.
State attorneys general. The September 1 dismissal closed the federal track without validating any theory, so state pathways now carry the whole load. The segmentation finding relocates the strongest theory: with broker access equalized the exclusion claims weaken, while the predicted harm concentrates on unrepresented consumers routed through discovery and first-contact architecture, which is core consumer-protection and steering jurisdiction. The natural experiment supplies a first-pass record requiring no cooperation, because IDX flags and dual-end rates sit in closing data, and civil investigative demand authority reaches the interaction data the paper marks as nonpublic. The Washington record transfers without discovery: the hearing deferrals and the concealment ratio and the “fully realized” and “absolute right” statements all sit beside a statute that conditions them.
MLS boards. First Look offers a candidate exportable equilibrium: absorb coming-soon marketing while preserving mandatory cooperative submission. The MindCast MLS Equilibrium Series frames the adoption decision inside the cooperative-transparency equilibrium.
Brokerages. Competitive advantage shifts toward obtaining the customer relationship rather than possessing inaccessible inventory, and the firm-level configuration decision is the strategic decision the next complaint will quote.
Portals. Attribution and contact buttons and lead-routing design carry economic consequence when relationship formation is the scarce asset.
Investors. The capital-markets question changes from how much private inventory Compass can accumulate to how much transaction flow Compass can internalize without exclusive inventory. Why Compass Needs Private Listings, The Inventory-Routing Premium — Compass, the Anywhere Merger, and the Multi-State Enforcement Window priced the routing premium the question now reprices.
Consumer advocates. The represented-versus-unrepresented distinction is the critical axis, because NWMLS-wide access may protect the former far more effectively than the latter.
XI. MindCast AI Proprietary Foresight Simulation Predictions
Eleven banded forecasts print below, frozen September 4 before the first First Look listing closed. Entries are numbered P for Primary Simulation Prediction and S for Secondary Simulation Prediction. Three primary predictions come first, and eight secondary entries fall into three classes: candidates awaiting stronger evidence, conditionals attached to the inherited forecasts, and forecasts carried from the August 31 register.
Primary Simulation Predictions.
P1 (62-68%): Washington’s market splits along buyer representation. Buyers who hire their own agent escape the old listing-side capture, because every NWMLS broker now sees every First Look property on day one. Buyers who approach a listing without an agent remain winnable through IDX withholding and attribution and first contact. The rival outcomes trail far behind: routing advantages strong enough to work on all buyers score 16-20% and total collapse of the capture economics scores 12-18%. Grading runs on evidence through June 30 of 2027, and the ranking is more certain than the exact probability. Identical results for agented and unagented buyers kill the split-market call, and uniform collapse across every configuration resolves the collapse call.
P2 (68-74%): Double-ended deals decline. Same-brokerage and dual-sided commission capture falls below its pre-6091 level once post-September closings mature, graded through June 30 of 2027. No decline kills the entry, and so does a decline that vanishes under property controls. The entry carries the strongest support in the release.
P3 (58-64%): The decline skips the strongest routing. Capture falls least on IDX-out listings and among buyers who arrive without an agent, which is where listing-side routing still operates. A decline that lands evenly across every configuration kills the entry. The entry is the test that separates a split market from the two rival outcomes.
Secondary Simulation Predictions. Entries S1 and S2 are candidates rather than released predictions, because their supporting analysis cleared a lower internal evidence bar and market data will promote or retire them. Entries S3 through S5 are conditional predictions attached to the inherited forecasts, and S6 through S8 carry from the August 31 register at their own bands.
S1 (60-65%), candidate: Compass withholds more First Look listings from IDX than its rivals. The gap survives property controls and shows by December 31, the first entry to resolve. Statistical parity with peer brokerages kills it. The entry rests on incentives rather than any documented company policy.
S2 (62-70%), candidate: The October 15 attribution rules move buyer inquiries toward listing agents. The lift shows beyond the September 4 First Look effect and concentrates among buyers without an agent, graded by March 31 of 2027. The entry depends on inquiry data that may never become public, and no shift around October 15 kills it.
S3 (76-84%), conditional: The inherited 3PM forecast lands as a hit. Washington 3PM adoption stays below 15% when the forecast’s December window closes.
S4 (57-65%), conditional: The inherited King County threshold is reached. Months before the September 4 break carry the result.
S5 (66-74%), conditional: Capture runs lower after September 4 than before it. The post-break rate falls below the pre-break rate inside the same measurement window.
S6 (79%), carried: Enforcement hits configurations, not First Look itself. Any official action targets specific public-marketing setups such as IDX-out inventory rather than the status as a category, released August 31 in the settlement paper.
S7 (68%), carried: The First Look template spreads. Peer MLSs adopt coming-soon rules faster than legislatures pass new statutes, graded by August 2027.
S8 (55-70%), carried: The hidden-history split draws scrutiny. Public attention lands on buyers seeing less history than brokers by March 2027.
Enforcement and diffusion carry no new bands here, because the August 31 register already holds both forecasts and duplicating them would double-count the record.
Inherited register entries print verbatim at original published bands and neither converts early. Original, verbatim: “The forecast that Compass’s 3PM adoption in Washington falls below 15 percent within six months of June 11 runs through December inside a routing environment First Look has changed.” Original: not less than 15 percent of Compass-listed residential transactions above $5 million in King County show intra-brokerage buyer-side capture during the April-through-December measurement window, from the Two-Gate record.
September 4 is labeled a structural regime break inside both measurement windows, and the original predictions stay preserved exactly as published. The conditionals above carry less evidentiary weight than the primary predictions and the originals stay untouched. Dynamic Predictive Game Theory Meets the Era of AI — Operationalizing Fudenberg’s Research Agenda with Cognitive Digital Twins supplies the method standard the grading follows.
📊 Investors: S1 resolves first at December 31. The earliest signal is configuration concentration rather than closings.
XII. Risk Mitigation
Each prediction carries an exposure and a set of unilateral mitigations, stated in the unit the stakeholder controls. Probability and severity run on separate axes, and the highest mitigation priority sits where severity is high at a moderate band rather than where the headline band is largest. Actions are analytic options rather than recommendations to any party, and MindCast does not provide legal or investment or fiduciary advice. Primary predictions receive full treatment and secondary entries receive one line each.
P1, the segmented equilibrium. Executives carry configuration risk: a strategy built for the wrong equilibrium spends conversion architecture where the run expects insulation, and the unit is listing-side share plus intake tracking. Unilateral options: set one firm-wide First Look configuration standard before volume accumulates, and build represented-against-unrepresented inquiry tracking from day one. Counsel carry the mirrored exposure, because consumer-protection theories aim at unrepresented-buyer routing and a dated intake record of representation status is the defense the theories will test. Policymakers carry a protection gap concentrated on unrepresented consumers, and complaint intake that distinguishes representation status converts the gap into a measurable record. Residual: segmentation magnitude stays unknown until interaction data surfaces.
P2, the overall decline. Brokerage revenue models built on pre-6091 internalization rates carry the largest exposure at the strongest band, and the unit is dual-side revenue through mid-2027. Unilateral options: rebase internalization assumptions now and price exclusivity at zero while pricing the attention assets above it. Investors mirror the exposure in the Washington book, and a haircut on internalization revenue pending matured closings is the conservative screen. Residual: the decline’s magnitude carries no released band.
P3, the segmented residual. Exposure concentrates where routing stays strongest: IDX-out inventory meeting unrepresented entry, and the unit is the number of IDX-out listings whose public-marketing configuration could create a separately chargeable violation on a noncompliance finding. Unilateral options for counsel: a conservative written definition of public marketing and a dated evidence log per IDX-out listing, the same record the carried enforcement entry makes valuable. Researchers and consumer advocates hold the preservation option, because early First Look data ages quickly and the represented-against-unrepresented axis is the record worth capturing first. The same intake record mitigates both P1 and P3 for different reasons. Residual: severity is high at a moderate band, which is exactly where mitigation spend belongs.
Secondary entries, one line each. S1: document independent IDX policy formation and avoid competitor coordination, which can create separate competition-law exposure. S2: portals should document lead-routing logic before October 15, since attribution implementation becomes evidence once inquiries route. S3: analysts keep Washington 3PM priced at zero adoption through December. S4 and S5: closed pre-break transactions remain reviewable, so records preservation is the cheap option now. S6 through S8: mitigation layers for the carried entries live in the August 31 register and are not duplicated here.
XIII. What to Watch
Seven observable events settle the open questions, and each has a public source. One: the remaining undisclosed settlement terms, the release scope and the definition of “investigate”, arrive with the filed agreement behind the September 1 dismissal. Two: week-one IDX distribution on First Look inventory supplies the first S1 evidence. Three: October 15 attribution implementation shows whether portals display IDX-out inventory at parity or with differential prominence. Four: November 15 broker-platform data delivery tests the final settlement stage.
Five: any DOL intake signal or interpretive guidance on “general public” begins resolving the carried enforcement entry. Six: peer-MLS board agendas and Governor Hochul’s pending decision on New York’s consent-model bill move the diffusion race. Seven: any Compass citation of the settlement in congressional or regulatory correspondence supplies the first import specimen for the Skillman boundary in Section VIII. One fork dominates: DOL’s posture on the IDX-out seam decides whether the statutory floor becomes behaviorally determinate or remains legally binding and operationally untested, because a passive enforcer paired with a peace-seeking cooperative leaves binding law without an enforcement history.
🏛️ Policymakers: the dominant fork is enforcement posture. A statute without a first enforcement action binds in law and stays undetermined in behavior.
💼 Executives: First Look is now a candidate template for peer MLSs facing the same pressure. S7 grades whether the model begins propagating across peer MLSs faster than statutory responses.
XIV. Conclusion
The settlement settles the wrong question for anyone still treating the dispute as a binary contest over private listings. Washington did not return to the pre-SSB 6091 market. Private brokerage access and cooperative access are no longer substitutes, every participating broker can obtain a First Look listing, and the strongest structural component of the old model does not survive intact. Neither did Washington create a market in which every participant encounters the same information through the same channel at the same time.
First Look equalized Layer 1 and left Layers 2 and 3 configurable. IDX choices move Layer 2 and attribution moves Layer 3, and each operates downstream from the inventory layer SSB 6091 constrained. The settlement’s real significance follows: the competitive battlefield moved.
MindCast predicted the move in March, before the statute took effect and before First Look existed. First Look now creates the institutional environment in which the prediction can resolve, and the result is not predetermined. If internal buyer capture and dual-ended rates fall materially despite the presentation and attribution advantages, the evidence narrows the commission-consolidation thesis: true inventory exclusion was doing most of the economic work. If the rates remain elevated, particularly among IDX-out listings or previously unrepresented buyers, the conclusion becomes more consequential: inventory exclusion was one implementation of a deeper architecture centered on controlling where the buyer relationship begins. SSB 6091 removed the strongest exclusion mechanism, First Look preserved the incentive, and the next question is whether the economics survive without the exclusion. The simulation expects fragmentation: weaker consolidation overall at 68-74%, with the remaining advantage concentrated where an unrepresented buyer becomes a represented one.
🏛️ Policymakers: the exportable design is the separation and the guardrails carry it. A template without them inverts Washington’s sequence.
📊 Investors: S1 grades first at December 31 and P2 grades on closings through mid-2027. The register is the pricing schedule.
