WHO GETS THE LISTING DATA? | PLAIN LANGUAGE SERIES | PART 3 OF 5
Three Answers From Three Places
A national brokerage, the country’s largest MLS, and Austin’s MLS each proposed a fix in the same summer. They agree on the problem and disagree on everything else.

Quick background for readers starting here: the MLS is the shared database of homes for sale that competing brokerages build together, on a trade, everyone contributes listings, everyone receives everyone else’s. That trade has broken down, because some firms now take data out without putting listings in, and others want to hold listings back while staying in. In the summer of 2026, three documents from three organizations proposed three different repairs. Here they are, in plain language.
Compass: membership carries the data. Compass, one of the largest brokerages in the country, presented its position to the industry group that oversees display rules. Its argument is the traditional bargain stated as a right. A broker who joins the MLS should receive the full database and should have its listings displayed by every other member. On this view the MLS should not sort members into tiers or ask how they earn their money. Compass is advocacy, not a rule; it binds no one, but it states the position that large brokerages will press.
CRMLS: access depends on use. The largest MLS in the country, California Regional MLS, circulated a draft rule in July that treats every use of the shared database outside the MLS’s own software as something that requires permission. Displaying other brokers’ listings, running analytics, building products, and feeding data to artificial intelligence tools each have their own rules, and most of them require a license from the MLS. The draft asks what a firm does with the data, not who the firm is. It has not been adopted at this time.
Unlock MLS in Austin: access depends partly on revenue. Austin’s MLS adopted its rule, effective September 15, 2026. It sorts every brokerage into one of three groups. Most brokerages use the MLS’s own tools and never take a feed of other firms’ listings at all; nothing changes for them. Brokerages that earn most of their revenue actually representing buyers and sellers, and that use the feed only for ordinary brokerage work, receive the data as part of membership. Everyone else who wants a feed must sign a commercial license and pay a fee. Unlock’s CEO explained the reasoning in a published column: cooperation is a two way street, every brokerage pays something, and what differs is whether the payment comes in dollars or in data.
Notice what all three share, because it is easy to misunderstand. All three accept that the database is valuable because working brokers build it. All three accept that the old, undifferentiated system no longer fits the real world. And all three reach, in different ways, for the same instrument; that is, some form of license that defines who may use the data and how. Where they part is the trigger. Compass says membership is the trigger. CRMLS says use is the trigger. Austin says revenue, with use as a backstop, is the trigger. Austin’s answer will be tested first, because it is the only one already in force, and whatever happens to it will shape what every MLS in the country tries next. The other articles in this series, each standing alone, explain the vocabulary these fights are conducted in and what to watch as they unfold.
