A National MLS Is Coming. But Who Controls It Changes Everything.

The push for a national MLS is accelerating. Multiple regional systems have recently announced plans to go national, and a prominent industry figure has floated a proposal to consolidate Americas fragmented, 550-plus MLS landscape into a single platform.

For some agents and brokerages, the idea sounds like progress. For others, including Courtney Poulos, founder and broker-owner of ACME | SERHANT. and a member of the SERHANT. CA founding team, the real question is not whether consolidation happens. It is who holds the keys.

I do not personally hate the idea of a nationwide MLS, Poulos says. But if one brokerage has too much influence, you can see how it weaponizes the MLS in favor of one operators policies.

The Civil War Nobody Wants to Name

Poulos describes the current moment in organized real estate as a civil war. Compass is facing an antitrust investigation in New York. Debate over a national MLS is splintering the industry along predictable lines. We need something that unifies our messaging, adds Poulos.

Her concern with a single national MLS is structural. If voting membership were distributed equally on an agent-by-agent basis, and one firm controlled 30% of American real estate transactions, the governance math would tilt quickly. What you thought was a democracy becomes a board overhaul, she says. Were all stuck, dominated by one brokerages point of view.

At the same time, she is not defending the status quo. Local MLSs have failed agents in critical ways: they did not prevent aggregators from capturing the consumer relationship, they have limited agents ability to brand and reach the public through public-facing listing portals, and they have not defended agent visibility or contact information in an era when data is leveraged.

A Nationwide License as the Missing Piece

Poulos has been developing an independent research proposal as part of her executive education at Harvard University, where she will complete the Advanced Management Development Program in July. Her proposal centers on a nationwide real estate license, modeled on the NMLS system used for mortgage originators.

Her argument is straightforward. In any given year, roughly 4 million Americans move across state lines. Agents who have built deep client relationships and local expertise cannot follow those clients without the cost and friction of obtaining multiple state licenses and joining multiple MLSs. Its cost prohibitive, she says. I would love a portable agency.

A national license paired with a well-structured national MLS could allow experienced operators to serve clients across markets while using AI for the compliance-heavy, state-specific regulatory work. Could an agent actually know all the rules and regulations across the country in all these different environments? No. But could we use AI for compliance, and then reestablish what makes a real estate agent actually an expert? Yes.

What Boutique Brokerages Should Be Watching

For independent brokerages, the risk in any consolidation scenario is being outmaneuvered before the rules are written. Poulos says the counterbalance to a dominant-player takeover of a national MLS would be representative governance: a leadership structure that includes independent brokerages, franchises, and unaffiliated agents, not just the largest volume operators.

Together, collectively, we are more powerful in that negotiation, she says. We could lobby as one nationwide organization instead of begging for change one MLS at a time.
