Zillow’s Samuelson: Undermining the MLS could bring regulators knocking

Exclusive coverage from CMLS: Samuelson cited Hill scrutiny of Compass and MRED and warned data restrictions could invite regulation

Bay Area housing and community
Curated News BriefBased on original reporting by HousingWire (September 30, 2026). The summary below is the Journal’s; the local analysis is original commentary by Omar Murillo.

According to HousingWire, Errol Samuelson, who leads industry development at Zillow, recently addressed real estate professionals at a major MLS conference with a sobering message about the direction of the industry. Samuelson drew on economic theory to explain that the MLS system faces a critical moment where individual players acting in their own self-interest could undermine the entire cooperative structure that benefits everyone. He referenced concerns about private listing networks and recent regulatory scrutiny from Congress as signs that government intervention may be on the horizon if the industry doesn't police itself.

Samuelson emphasized that the transparency and open cooperation built into the traditional MLS model is what makes American real estate markets the strongest in the world. When individual MLSs start hiding information like listings or metrics from public view, he argued, they're gradually eroding the marketplace that sellers and buyers depend on for fair access and competition. If this degradation continues to hurt consumers, Samuelson cautioned, those consumers will turn to their elected representatives, which could trigger the very government regulation nobody wants to see.

In response to criticism that companies like Zillow extract value from the MLS without contributing, Samuelson pointed out that appraisers provide essential services to the industry without ever listing a property, yet nobody questions their role. He also noted that real estate brokers used to spend enormous sums advertising in newspapers before internet portals emerged, and now they receive free exposure through sites like Zillow, which he framed as a massive indirect contribution to the brokerage community.

On the emerging issue of artificial intelligence and MLS data, Samuelson acknowledged that some MLSs are taking overly restrictive approaches by either claiming ownership of any AI-generated product or blocking AI use altogether. He expressed skepticism that either extreme would work in practice, noting that agents will find workarounds if they feel the MLS is blocking beneficial innovations. Instead, he advocated for smart guardrails around AI usage, using Zillow's own controlled systems as an example of how data can be protected while still enabling helpful tools.

Samuelson concluded by noting that while most MLS leaders want the cooperative system to continue functioning well, the industry is facing unusually intense pressure from a vocal minority. He suggested that the decisions made by MLS executives in the coming months could have lasting consequences for how real estate operates in America, and urged them to stay focused on what made the system successful in the first place.

What I am seeing locally here in the Bay Area and East Bay is that our MLS transparency has always been one of our greatest competitive advantages. When properties are hidden or data becomes opaque, it doesn't create some advantage for individual brokerages, it just makes the market work less efficiently for everyone involved. I think Samuelson's warning about regulation is worth taking seriously, because Washington has already shown interest in real estate practices, and the last thing any of us want is heavy-handed government rules dictating how we do business.
