Google went national. Now who negotiates for the MLS?

Google’s announcement Thursday that it will display home listings inside mobile search results in all 50 states reads like an ad product update. It is not. It is the arrival of a new national channel for listing data, and it forces a question this industry has dodged for a year: when a trillion-dollar platform wants MLS data, who sits on the other side of the table?

What Google built

The expanded Local Services Ads show price, photos and home details inside mobile search. A buyer can call, message or book an appointment with a local agent without leaving the results page. The listing data flows through HouseCanary’s ComeHome platform under agreements with participating MLSs. Three MLSs participate today: CRMLS, San Diego MLS and My State MLS. Coverage expands market by market through the summer, with full national reach as the stated goal.

The strategic fact is simple. Google sits in front of every consumer destination in real estate. Zillow, Redfin, Realtor.com and every brokerage website depend on traffic that begins with a Google search. Until now, Google passed that demand downstream. Now it plans to satisfy a piece of it inside the results page itself.

The timing could not be worse for Zillow

Zillow’s power in every negotiation, with MLSs, with brokerages, and now in federal court, rests on a single asset: it is where buyers look. That asset is the reason cutting off Zillow’s feed became a federal case, and it is the reason a judge ordered MRED to restore that feed. The entire dispute assumes Zillow is the indispensable window to the buying public.

Google’s expansion chips away at that assumption. Every home search satisfied inside a Google results page is a search that never reaches a portal. Zillow’s moat was never its data, which comes from the industry. Its moat was attention. Google is the one company on earth with more of it.

And once again, the brokerage best positioned to benefit is Compass. Compass’s argument throughout its standoff with Zillow has been that no single portal is essential to a seller’s outcome. Every new place a buyer can find a home weakens the claim that withholding listings from Zillow harms sellers. I have made this observation before, and Thursday’s news strengthens it. In every scenario of the portal wars, Compass finds an upside, and the risk lands on the traditional MLS system.

Except this time, there is a twist worth dwelling on.

This time the MLS is the supply

HouseCanary’s own announcement frames the program as an answer to a fragmenting marketplace, one that lets buyers discover listings from the most complete and validated source available: the MLS. Read that again. After a year in which the largest brokerages built private networks and the portals built pre-market feeds, the largest search company on earth evaluated the entire landscape and concluded that the best source of listing data in America is still the MLS.

That conclusion did not come from NAR. It did not come from an MLS trade group defending its turf. It came from a buyer of data with every option on the table. Private brokerage inventories are partial by design. Portal pre-market feeds are partial by contract. The MLS is the only complete picture of the market, in the places where it still gets the listings.

This gives MLSs something they have not had in 20 years: leverage. The question is whether they will use it.

Three reasons MLS leaders should read the fine print

First, the deal-by-deal pattern. Three MLSs signed individually, through one middleman, on terms that have not been made public. HouseCanary has promoted the program as free for MLSs. Free for how long? With what rights over the data? With what say in how leads get routed? Nobody outside those agreements knows. When 500-plus MLSs each negotiate alone against one national counterpart, the terms get written by whoever signs first and accepted by everyone who signs after.

Second, the middleman is a brokerage. HouseCanary holds brokerage status, and the original pilot was pulled back after objections over how the company had used that status to access listing data. The relaunch came with MLS and brokerage buy-in, which is real progress. But the basic fact remains: the pipeline between America’s MLSs and Google runs through one private company. And there is already a side door. eXp sends its Coming Soon inventory directly to ComeHome, brokerage to platform, no MLS required. If that route widens, Google stops being a reason to list on the MLS first and becomes one more pre-market stage.

Third, the lead economics. This is a paid product. Agents enroll in Local Services Ads and pay for the calls, messages and appointments generated by listings their own cooperation created. The industry has run this experiment before. It contributed its data to the portals at no charge, then spent two decades buying back its own demand, one lead at a time. Running the same play against a counterpart the size of Google, with no negotiated guardrails on data use and lead routing, would be a generational mistake.

The answer is one table

None of these risks argues for sitting out. Google’s buyers are real, the exposure is real and an MLS that stays out simply makes its brokers’ listings harder to find. The risks argue for something else entirely: MLSs should answer Google the way Google approached them — as one national counterpart.

The Council of Multiple Listing Services (CMLS) is the natural convener. What this moment calls for is a standing group, owned and controlled by the MLSs themselves, with the authority to negotiate data licensing terms with national platforms. Usage limits. Attribution rules. Lead routing standards. Audit rights. And a permanent seat at the table for whoever calls next, because Google will not be the last. Every AI company building a home search answer will come for this data too.

This is not a new portal. It is not a new company with something to sell. It is a negotiating table, and the absence of one is the single biggest strategic gap in organized real estate today.

CMLS Open House 2026 convenes at the end of September. By then, Google’s rollout will be months along, and the early agreements will be hardening into the default. The agenda writes itself.

The bottom line

For a year, the debate has been whether the MLS still matters. On Thursday, Google answered it with the most credible endorsement possible: it built its national home search on MLS data. The system everyone keeps writing off turned out to be the one asset a trillion-dollar company could not replicate.

Google did not just launch an ad format. It put a national price on the value of MLS data. The only question left is whether the people who own that value will show up to collect together, or hand it over one signature at a time.
