826 Letters of Support for Initiative to Create National U.S. Real Estate Listings Database

Key Facts

2Participating brokers must enter a property into the initiative’s database within one business day of signing a listing agreement.

4The initiative named 4 companies as initial participating members.

The Open Real Estate initiative had received 826 letters of support from real estate brokerage leaders as of November 2, 2026, RealtyWire reported, signaling expanding backing for a project aimed at broadening access to housing inventory and listing data. Independent firms accounted for 493 letters, or 59% of the total. The initiative said, however, that letters of support do not mean their authors have committed to joining, so the figures do not represent confirmed membership. The numbers come amid an effort to aggregate listing data and distribute it to brokers and market institutions. AGNT, HomeServices of America, Keller Williams and RE/MAX Group founded the initiative, according to the FAQs published on its website.

The concept is a system brokers use to enter listings with a minimum set of standardized fields, then store them in a national repository and make them available through a distribution mechanism that shares value with data creators, according to the initiative’s description. The National Association of Realtors said listings would be entered once and then shared with brokerage firms and agents that had agreed to the platform’s rules. At the same time, the data would be distributed to local multiple listing services, search sites and real estate portals, appraisers and data services. The initiative therefore focuses on how listing data is collected and exchanged among parties, rather than creating a new consumer search portal. The association described the project as a listing distribution platform that complements local multiple listing services and real estate portals.

The initiative’s rules require participating brokers to enter a property into the database within one business day of signing a listing agreement with the homeowner. After entry, the listing broker can choose to limit access to the property to eligible participants or distribute the listing publicly. Under the participant-only option, only agents affiliated with participating brokerage firms can see the property. It also cannot be marketed publicly by either the listing agent or the agent’s firm, according to the FAQs. These options leave the decision on the scope of a listing’s availability to the listing broker, while determining which audience can view and market it.

The initiative says privately marketing properties can limit market transparency and may create gaps in the collection of price and sales data. It says those gaps could affect the ability of banks, appraisers and insurance companies to value properties appropriately. Local multiple listing services, by contrast, retain their own rules; the initiative neither sets nor changes them, according to the FAQs. That means the project is presented as a data-sharing layer alongside local systems, not as a replacement for them. The association said the six months following the announcement would be devoted to educational sessions and work with local multiple listing services and stakeholders on governance and technology plans.

Listings entered into the system remain the property of listing brokers, HousingWire reported, while proceeds from monetizing the aggregated data would be split equally among participating brokers. The monetization method has not yet been clarified, leaving part of the initiative’s business model undetermined. The publication said joining requires no fee and membership is open to participating licensed brokerage firms and residential franchises, as well as their agents. Tamer Boulage also said Compass was invited to become a founding member, but the group’s leaders did not disclose the company’s response, and it did not respond to the publication’s request for comment. The invitation places the company in the discussion about participation without confirming that it has joined the initiative.

Against the backdrop of competition for listing access, the Associated Press reported in February 2026 that an agreement between Compass and Rocket would allow listings to appear on Redfin and could add more than 500,000 listings to its website and app. The agency reported at the time that Compass shares fell 1.6% in after-hours trading following the announcement, after ending the regular session up 5.2%. In New York, Compass accounted for 31.7% of the value of closed deals in September 2026, up from 31.5% in August, according to a Relitix report. These earlier figures place the project within broader competition for access to listing data and its scale, and do not represent market performance on the day the initiative was announced. The initiative’s companies presented the project on October 26, 2026, according to the National Association of Realtors.

The group was still selecting technology vendors, and the association said it expected to complete the selection in the first months of 2027. The initiative’s website also identified Brown Harris Stevens, Lamacchia Realty, Samson Properties and Windermere Real Estate as initial participating members. The planning period is set to include educational sessions and collaboration with local multiple listing services and stakeholders to develop governance and technology plans. The launch remains contingent on completing this work and selecting vendors. The letters of support announced by the initiative as of November 2 do not, by themselves, make their authors committed members.
