Starting this summer, sellers in the Mid-Atlantic will be able to keep their home’s price, address, photos, days on market and price history off Zillow and other search portals, while the listing itself remains fully syndicated, according to a rule change from Bright MLS.
The new controls, built into Bright MLS’s 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, a Bright broker’s distribution choice has been essentially binary: send the listing to consumer sites or not. The upcoming update will make that check more detailed. At the direction of the seller, a listing may appear on portals with individual fields flagged as not being displayed.
Other rule updates aim to prevent Bright MLS members from uploading MLS data to artificial intelligence sites, while adding options for those members to connect their AI tools directly to Bright MLS.
The changes take the industry’s listing wars into new territory. Over the past year, the battle between portals, brokers and MLS has focused on which listings reach consumer sites, and when. Bright’s updates are about what these sites are allowed to display once a listing comes in.

“This policy is primarily focused on one thing: giving our subscribers more options and more control over how their listings appear on consumer websites, including new privacy tools for merchants like price and photo suppression,” said Rajeev Sajja, Bright’s chief AI and product officer.
What’s changing
The Summer Update formalizes a four-tiered marketing framework – and every listing, regardless of tier, must still be entered into Bright within two days of signing the listing agreement.
The four levels: “Registered” (in the MLS, no distribution anywhere); “Office Exclusive” (no Bright distribution inside or outside the MLS, although the agent may advertise anywhere); Coming Soon or Active with Internet “No” (shared with all MLS subscribers, not displayed on consumer sites); and Active with Internet “Yes” (full syndication – now with the new field suppression instructions available).
Beginning later in 2026, homes sold as Office Exclusives will count toward agents’ and brokers’ credit calculations, bringing MLS production into the measured record for the first time.
Bright is also implementing changes that appear to strike at the heart of Zillow’s policy that aimed to restrict public marketing of real estate listings that are not also available on the portal, a policy known as Zillow Listing Access Standards that has been at the center of a fierce debate in the industry.
According to the update, if a listing is marketed as Office Exclusive and later converts to full syndication, consumer sites can exclude it based on “objective criteria” of how it was previously marketed — essentially a Zillow-style ban for that category.
But if the listing was listed in the MLS as Coming Soon or Active for Collaboration – even if the Internet “No” is invisible to consumers – portals like Zillow can’t rule it out based on previous marketing.

Its compass shape
The rule changes come two months after Bright became MLS’s fourth and largest MLS partners with Compass International Holdings at a time when the mega brokerage is trying to redefine how, when and where listings are brought to market.
Compass’ three-phase marketing strategy, which includes an off-MLS marketing period in addition to an upcoming listing period before the listing is widely distributed through public portals such as Zillow, is a key target of Zillow’s Listing Access Standards.
Compass has agreed to make its nationwide listing data available to all Bright subscribers, an agreement it has made with at least three other major MLSs, including MRED in Chicago, Realtracs in Nashville and the MLS CLAW in Los Angeles.
Bright’s updated rules allow agents to prevent public portals from showing price history, market days, and other data pieces that Compass CEO Robert Reffkin has repeatedly called “negative insights.”
Sajja described the update as an “evolution” of Bright’s rules to support how agents today try to market properties to their sellers.
The rule changes will prevent recipients of Bright’s data feeds, including the portals, from excluding listings that comply with the updated rules, even if the listing has been publicly marketed without being available for display on the portals.
But Sajja did not specify whether Bright would disconnect data feeds from portals like Zillow if that company continued to block listings that had been publicly marketed without being available on Zillow.
“We haven’t had a conversation with anyone about losing IDX feeds,” he said. “Our goal is to make sure that everyone who receives our feed adheres to our photo and price suppression policies… That’s what we would enforce – that’s really what we’re entitled to.”
Notably, MRED briefly shut down Zillow’s direct mentions feed in May, before a judge ordered the feed reinstated while an ongoing lawsuit was underway.
When asked if the rules update was a condition of Bright’s new partnership with Compass, Sajja had a one-word answer: “No.”
“We don’t choose a particular broker strategy. Each broker competes at different levels of strategy,” Sajja said. “Some people want more exposure, some people want limited exposure and then more exposure. All we want to do as an MLS is give them all the options so they can compete at their own strategy level.”
Plugging AI into the MLS
Bright presents other upcoming updates related to MLS data within artificial intelligence in preparation for a world where consumers stop searching for portals and start asking for AI assistants.
Bright will roll out a way for members to connect AI tools to the MLS for instant access to accurate data distributed by subscribers, Sajja said, citing concerns that existing AI models were circulating incorrect information.
“I asked for a list-to-sales price ratio for 2026 in my neighborhood,” Sajja said. “All three [large language models] came with enough differentiation that it confused me more than it taught me… If they were all connected to Bright’s data with the MCP, the answer would be exactly the same.
The updates are “infrastructure for the AI age,” Sajja said, or rules that keep the MLS record current and verified so that AI engines call the MLS first instead of offering scraped data.
Smart members won’t be able to download data from the MLS and upload it to an AI tool if those tools train on that data, although Sajja acknowledged that rule will be difficult to enforce.
The argument reflects a broader repositioning among major MLSs. Bright appointed Sajja as its first Chief Artificial Intelligence Officer in January, with a mandate to make Bright ‘AI-native’. And at the T3 Leadership Summit in April, Bright CEO Brian Donnellan and CRMLS CEO Art Carter agreed that MLSs are positioned to become the authoritative data source that AI systems rely on as hallucination remains a problem.
“We are actively working – it is in the final stages of testing – to enable MCP-like access to Bright’s data,” Sajja said.
Several of the major portals have announced partnerships with AI companies, such as Zillow’s app within OpenAI’s ChatGPT. These types of integrations are still allowed as long as they don’t train the AI model on the data, Sajja noted.
“It just passes the query to Zillow and frames the Zillow experience into a ChatGPT,” Sajja said. “It’s honestly a pretty limiting experience. If I were using AI, I would never look for houses there.”
