Unlock MLS, the Austin, Texas, multiple listing service run by the Austin Board of REALTORS, told Compass on Oct. 6 that it will keep fining agents who market listings publicly without putting them in the MLS β rejecting a demand that came with the threat of a federal antitrust suit.
Chief Executive Emily Girard laid out the refusal in a letter to subscribers published the same day, and said the MLS was posting both Compass’s demand letter and its own response in full so members could draw their own conclusions.
According to Girard, attorneys for Compass wrote to Unlock MLS on Sept. 8 threatening a federal antitrust lawsuit unless the MLS agreed, by Oct. 6, “to stop applying any consequence when a listing is publicly marketed without being shared through the MLS in direct violation of Unlock MLS rules.” The deadline passed without that assurance.
She also indicated the letter was not tailored to Austin: “We understand that Compass, Inc. has sent demand letters to many MLSs, apparently without consideration of the very different policies of those MLSs regarding the enforcement of the rule Compass, Inc. complains of.”
The rule in dispute
At issue is the Clear Cooperation Policy, the National Association of Realtors rule under which a listing broker must submit a listing to the MLS within one business day of marketing the property to the public. Every Realtor association MLS is required to adopt it. Unlock MLS serves more than 17,000 agents and brokers across more than 3,600 offices in Central Texas.
Girard’s framing of the stakes went past the specific rule. “Compass’s demand is not about NAR, and it isn’t about any single rule,” she wrote. “It’s about whether Unlock MLS may have rules at all, and whether we can enforce them uniformly to protect the integrity of the system you rely on. A marketplace whose rules can be set aside under threat of litigation isn’t a marketplace you can depend on.”
She added that Unlock is required as an NAR-affiliated MLS to maintain the policy, and that the organization has “openly expressed our reservations with it” β a notable concession in a letter defending its enforcement.
What enforcement actually looks like
Much of the letter is devoted to the penalties themselves, and the numbers are modest. A violation draws a courtesy notice and a single $100 fine; if the subscriber responds and pays, the matter closes. Escalation happens only when a notice goes unanswered or a fine unpaid, and the next steps are up to two reminder notices, a written warning and a compliance workshop, each granting more time to resolve it.
Only after a subscriber declines all of those does the matter potentially reach a hearing, where the maximum fine is $500. Suspension is not among the possible sanctions. “Literally no Unlock MLS subscribers have required a hearing for a CCP violation,” Girard wrote.
That detail is doing real work in the argument. If no Austin subscriber has ever reached a hearing, the restraint Compass is challenging has in practice amounted to $100 notices that recipients pay and move on from. “Our experience shows that a complete marketplace isn’t built with a hammer,” Girard wrote.
Flex, and the data behind it
Unlock MLS’s alternative to office exclusives is a product called Flex, which lets an agent market a listing privately inside the MLS without public internet display and without accumulating days on market or price-change history. Girard said it was developed in close conversation with brokerages in the market β “ironically including Compass itself.”
The letter supplies usage figures. Since August 2025, nearly 3,800 agents across more than 1,100 offices have used Flex. Nearly three in four Flex listings later moved to full MLS exposure once sellers were ready. Among completed sales, Girard said, nearly 60% of listings that used Flex sold without a price reduction after going to full exposure, against 42% of listings that did not use Flex.
Those are the MLS’s own numbers about its own product, and the comparison does not control for why a seller chose Flex to begin with. But it is a direct answer to the argument that a cooperation rule leaves sellers no private option: “Flex is a bridge into the marketplace, not a way around it,” Girard wrote.
A second MLS holds the line
The Austin refusal arrives alongside a different tactic in California, where the California Regional MLS sued Compass first, asking a federal judge to declare its listing rules lawful. Elsewhere Compass has reached an accommodation: the Northwest MLS in Washington added a “First Look” category to settle an antitrust suit, and Compass separately launched a program opening listings from nine brands to buyers at any brokerage.
Read together, those responses suggest the demand-letter campaign is producing market-by-market outcomes rather than one industry answer β roughly what Girard’s complaint about untailored letters implies. An MLS with a $100 first-offense fine and no suspensions has a different record to defend than one with harsher penalties.
Girard closed by noting that Compass “is one of our largest customers and a valued part of this market,” that the Austin market was named in copycat commission class actions before the NAR settlement, and that litigation “pulls our attention away from serving you” while consuming subscription dollars. “Our door has been and remains open to Compass, Inc.,” she wrote.
