Starting this summer, Mid-Atlantic sellers will be able to keep their home’s price, address, photos, days on market and price history protected from Zillow and other search portals, while the property itself remains fully syndicated, according to a rule change made by Bright MLS.
The new controls, incorporated into Bright MLS’ listing entry system, are the centerpiece of a rules update at the nation’s second-largest multiple listing service, which serves approximately 95,000 subscribers in six mid-Atlantic states and Washington, DC.
Until now, Bright Brokers’ distribution choices were essentially binary. Either you submit your list to a consumer site or you don’t. Future updates will make that control even more granular. At the seller’s direction, listings can be displayed in the portal with individual fields flagged as hidden.
Other rule updates focus on stopping Bright MLS members from uploading MLS data to artificial intelligence sites and adding options for members to connect AI tools directly to Bright MLS.
This change will move the industry’s listing wars into a new phase. Over the past year, the battle between portals, brokerages, and MLSs has centered on which products reach consumer sites and when. Bright’s update focuses on what those sites will be allowed to display once the list arrives.

“These policies primarily focus on one thing: giving consumers more options and more control over how their products are displayed on consumer websites, including new seller privacy tools like price and photo suppression,” said Rajeev Sajja, chief AI and product officer at Bright.
what is changing
The summer update formalizes a four-stage marketing framework, and all listings, regardless of stage, must be registered with Bright within two days of signing a listing agreement.
Tier 4: “Registered” (not distributed anywhere on the MLS). “Office Exclusive” (Brokers can advertise anywhere, but there is no Bright distribution inside or outside the MLS). Coming Soon or Active on the Internet “No” (shared with all MLS subscribers, withheld from consumer sites). Active on the Internet “Yes” (full syndication – new field restraining orders now available).
Starting in late 2026, homes sold as office-only will count toward agents’ and brokers’ “credit” calculations, marking the first time they’ll be included in non-MLS production measured records.
Bright is also implementing changes that appear to go to the heart of Zillow’s policy, known as the Zillow Listing Access Standards, which seeks to restrict public marketing of real estate listings that are not available on the portal either, a policy that is at the center of intense debate in the industry.
With this update, if a listing was sold as an Office exclusive and later switched to full syndication, consumer sites could exclude it based on “objective criteria” of how it was previously sold, effectively blessing a Zillow-style ban on that category.
But if the listing is listed as coming soon or working in the MLS, portals like Zillow can’t exclude it based on prior marketing, even if it’s an Internet “no” that’s invisible to the consumer.

The rule change comes two months after Bright MLS became the fourth and largest MLS to partner with Compass International Holdings, and comes at a time when giant brokerages are redefining how, when and where they go public.
Compass’ three-tier marketing strategy includes near-term listing periods before listings are widely distributed via public portals like Zillow, as well as non-MLS marketing periods, which are the primary targets of Zillow’s listing access criteria.
Compass has agreed to make national listing data available to all Bright subscribers, joining at least three other major MLSs, including MRED in Chicago, RealTrax in Nashville, and MLS CLAW in Los Angeles.
Bright’s updated rules will allow agents to prevent public portals from displaying price history, days on market and other data that Compass CEO Robert Refkin has repeatedly called “negative insights.”
Saja characterized the update as an “evolution” of Bright’s rules to support how today’s real estate agents seek to market properties for sellers.
With this rule change, recipients of Bright data feeds that include portals will no longer be able to exclude listings that follow the updated rules, including listings that were publicly sold without being viewable on the portal.
However, Sajja did not say whether Bright would cut off the data feeds that power portals like Zillow if the company continues to block publicly available listings that remain unavailable on Zillow.
“We have not discussed the loss of the IDX feed with anyone,” he said. “Our goal is simply to ensure that anyone who receives our feed follows our photo suppression, price suppression policies…That’s what we enforce, and that’s what we’re really entitled to.”
MRED specifically temporarily cut off Zillow’s direct listings feed in May before a judge ordered the feed to be restored while an ongoing lawsuit progressed.
When asked if this rule update was a condition of Bright’s new partnership with Compass, Saja simply answered, “No.”
“We don’t endorse any particular broker strategy. Every broker competes on a different strategic level,” Saja said. “Some people want more exposure, some people want limited exposure and then more exposure. What we want to do as MLS is give them all the options and allow them to compete on their own strategic level.”
Connect AI to MLS
Bright plans other upcoming updates related to MLS data within artificial intelligence in preparation for a world where consumers stop searching portals and start asking questions to AI assistants.
Citing concerns that existing AI models are circulating misinformation, Saja said Bright will roll out a way for members to connect AI tools to their MLS, giving them direct access to the exact data being circulated.
“I asked for the ratio of list price to sales price in 2026 in my neighborhood,” Saja said. “All three [large language models] I came up with enough differentiation that I was more confused than educated… Even if they were all connected to Bright’s data using MCP, the answer would be exactly the same. ”
Saja said these updates are “infrastructure for the AI era,” rules that keep MLS records up to date and verified so that AI engines call the MLS first, rather than providing scraped data.
Bright members will no longer be able to download data from the MLS or upload it to AI tools if the MLS conducts training on that data, but Saja acknowledged that rule would be difficult to enforce.
This discussion reflects a broader repositioning among large-scale MLSs. Mr. Bright appointed Mr. Saja as the company’s first chief artificial intelligence officer in January, tasking him with making Mr. Bright an “AI native.” And at the T3 Leadership Summit in April, Bright CEO Brian Donnellan and CRMLS CEO Art Carter agreed that while hallucinations remain an issue, MLS is positioned to become the trusted data source that AI systems rely on.
“We are actively working, although currently testing and in the final stages, to allow MCP-type access to data in Bright,” Saja said.
Several major portals have announced partnerships with AI companies, such as OpenAI’s Zillow app within ChatGPT. Sajja said these types of integrations are still allowed as long as the AI model is not trained on the data.
“Simply pass your search to Zillow, and the Zillow experience is built within ChatGPT,” Sajja says. “Frankly, it’s a pretty limiting experience. If I were using AI, I would never go there to look for a house.”
