MLS Data Belongs to Us, Agents and Brokers, Time to Take It Back

The war for the right to monetize our, agent’s and broker’s, data from our local MLS boards is not happening during Sunday open houses or in living rooms. It’s being waged in federal courtrooms and corporate boardrooms where the value of our shared data—there would be no Redfin or Zillow or any other platform monetizing MLS data—is being coopted by people that feel entitled to have and monetize it. For over a century, the Multiple Listing Service has functioned as a transparent clearinghouse that ensured every buyer had a fair shot and every seller received the benefit of real competition. That foundation is now under direct assault by multibillion-dollar platforms that seek to co-opt local data and monetize it for the benefit of shareholders rather than the communities we serve. Big Tech’s Curation Problem The insincerity of the modern real estate landscape is that the very platforms that promise transparency have built their empires by curating and gatekeeping our information. Zillow and Redfin generate billions in revenue by taking the raw data provided by local agents and wrapping it in lead-generation software to sell it back to those same agents. Zillow Group reported over $2.2 billion in revenue for 2024. These platforms act as digital museums where the experience is designed to funnel consumers toward paid advertisements rather than the direct expertise of a local professional. This curation is never neutral and always moves the consumer toward outcomes that favor the platform’s bottom line. While an agent’s search on a local MLS allows for unfiltered access to every detail, corporate portals use algorithms to rank listings based on engagement potential and profit margins. The Industry You created that listing. You photographed the property, wrote the description, negotiated the terms, and uploaded it to your local MLS. That work—your intellectual and professional labor—is now being monetized by companies that contribute nothing to the actual transaction.  Zillow and Redfin gained access to your data by becoming MLS participants themselves and signing data-feed contracts under established IDX and syndication rules. Zillow started with direct syndication deals, negotiating individual agreements with hundreds of MLSs and brokerages, then created licensed brokerage entities and joined local MLSs as participants, qualifying for standardized IDX feeds. Redfin, operating as a traditional brokerage from day one, joined each local MLS as a broker participant, paid fees, and ingested broker-level data feeds directly. Both platforms use automated MLS technologies—RESO Web API and IDX feeds—to receive near-real-time updates, all within contractual frameworks the industry approved. They didn't steal the data. They simply asked for it, and we said yes. The legal access rests on a premise that sounded reasonable at the time: hold a brokerage license, join the MLS, and sign the rules. IDX policy explicitly allows MLS participants to display other participants' listings on consumer-facing websites, subject to opt-out provisions and display standards. By joining thousands of local MLSs across the country, Zillow and Redfin positioned themselves not as outsiders but as broker-members entitled to the same data feeds as any independent agent. But there's a critical difference between displaying a listing and owning the relationship. The industry, eager for broad exposure, facilitated this transition—first through the DOJ-mandated dismantling of restrictive VOW policies, then through voluntary participation in IDX syndication. We handed them the keys to our data, they built a wall around the information, monetized the consumer relationship, and now charge us to reach the very buyers we created that listing for in the first place. We complain about the toll they charge to walk through a door we unlocked ourselves. The question now is whether we have the will to lock it again. NAR’s Clear Cooperation: A Line in the Sand The National Association of Realtors recognized this threat and created the Clear Cooperation Policy to stop brokers from hoarding listings and steering buyers only to the homes they controlled. The rule is simple: once a broker publicly markets a home, it must be listed on the MLS within one business day. This ensures every buyer has a fair shot and every seller gets the benefit of real competition. But the enforcement of that rule has always been messy. The policy itself was a response to the rise of "pocket listings" and private networks that functioned as dark silos of information. For decades, the MLS has been fighting a rearguard action against fragmentation, and the tools at its disposal are being eroded from multiple directions. Compass vs. The Open Market The threat has escalated from mere monetization to an outright legal challenge to the rules that prevent housing discrimination. Compass International Holdings is currently challenging the Clear Cooperation Policy in federal court, arguing that requiring a home to be listed on the MLS within one business day is an antitrust violation. Their goal is to create an "invisible market" of private exclusives marketed only to their vetted network of wealthy clients. The lawsuit filed in Seattle against the Northwest Multiple Listing Service seeks to invalidate the timing requirements that ensure every buyer sees every home. If Compass and its corporate allies succeed, the MLS could become a secondary channel for the scraps left behind by private networks. This is the definition of digital redlining where access to housing is determined by who you know and which brokerage you can afford to hire. Research shows that homes sold through private off-market networks sell for significantly less than those exposed to the open competition of the MLS. In California, the gap can reach nearly 4 percent, which translates to tens of thousands of dollars left on the table by sellers who were sold on the idea of exclusivity. The Local Board’s Secret Weapon Local realtor boards and MLSs currently hold the only weapon capable of stopping this corporate fragmentation. The power of the industry still rests in the local MLS because it remains the only source of real and verified data. By bringing the "front door" back to the local level through public-facing portals we can eliminate the need for corporate intermediaries. A consumer who visits a local MLS portal sees the same raw data that agents rely on without the "featured agent" boxes or algorithmic nudges that define the big portals. The National Association of Realtors has recognized this shift by moving toward greater local discretion for MLS operations. New policies taking effect in January 2026 allow local boards to decide how to grant access and how to handle their public-facing presence without national mandates. This is the moment for local boards to reclaim their relevance by proving their value to the consumer directly. We must stop being the back-office data provider for our competitors and start being the primary resource for our communities. Your Move The Compass acquisition of Anywhere Real Estate proves that the industry is consolidating to capture every possible cent of the transaction. The $1.6 billion deal creates a vertically integrated ecosystem designed to keep title, escrow, and mortgage fees inside a single corporate wall. This consolidation only works if the company can control the flow of the listing itself. By defending the MLS and promoting local portals we are defending the independence of the individual agent and the choices of the consumer. We are at a crossroads where the choice is between a unified marketplace or a tiered system of private clubs. The battle for clear cooperation and the survival of the MLS will define the next fifty years of homeownership in America. Bringing the power back to local boards is not just a strategic move for the industry but a necessary step for fair housing. Local boards must act now. Evaluate your public-facing portal. Ensure it provides unfiltered access to every listing. Promote it aggressively to your consumer base. Partner with platforms like Realty Times to amplify your reach. The decision is no longer passive; it is a tactical choice about what kind of market we want to be. The front door belongs to the public, not to a corporate algorithm. Let’s take it back.
