Game Over for Sneak Peek Listings: Redfin Joins Zillow in Banning Private Listings Without MLS Debut

Redfin is the latest major portal to take a firm stand on listing transparency, announcing it will no longer display homes that are publicly marketed before hitting the MLS.

The decision follows a similar move by Zillow and comes in response to updates made to the National Association of Realtors’ Clear Cooperation Policy—changes that allow local MLSs to create delayed marketing options for agents. Under the revised policy, agents can hold back listings from full public exposure for a limited time, so long as the MLS has an exemption process in place.

Redfin’s leadership sees that as a potential loophole.

“If a listing is marketed before it’s on the MLS, we’re not showing it,” said Redfin CEO Glenn Kelman. “We’re drawing a line. Either it’s available to everyone or it’s not.”

Kelman is also calling on MLSs to create a “coming soon” category that hides certain data points like days on market and price history to help sellers preserve momentum without gaming the system.

The move has sparked debate among brokerages. Companies like eXp and NextHome have backed Redfin’s decision, citing the need for a level playing field. Others—including Compass and @properties—warn it could restrict how agents market homes and limit client strategies.

Meanwhile, Homes.com, now the second-most visited real estate site, is taking a different route. It says it will continue displaying all listings, regardless of whether they were marketed pre-MLS.

As competition heats up among real estate portals, Redfin’s move signals a broader industry shift toward stricter enforcement of listing standards—and a potential reckoning for pocket listings.


A pocket listing is a property for sale that isn’t publicly advertised or listed on the Multiple Listing Service (MLS). Instead, it’s marketed privately—often shared only with a select group of buyers, agents, or through the listing agent’s personal network.

Here’s the breakdown:

  • Not on the MLS: So the general public and most agents won’t even know it’s for sale.

  • Limited exposure: Only certain buyers get access, which can limit competition.

  • Why it’s used:

    • Sellers want privacy (celebs, wealthy clients, etc.)

    • Agents want to double-end a deal (represent both buyer and seller)

    • To test pricing or prep the market quietly

Why it’s controversial:

  • Fair housing concerns: Not everyone gets a fair shot at buying the home.

  • Reduces transparency: Can lead to discrimination, steering, or inequity.

  • Hurts competition: Fewer offers can mean a lower selling price for the seller.

The recent policy shifts by Redfin and Zillow aim to curb this practice by requiring listings to go live on the MLS before they’re publicly marketed—or else they won’t be featured on the big platforms.
