Here’s what you’ll get from the next five minutes: a clear read on the single most consequential power move in New York residential brokerage this year, why it matters far beyond residential, and what it signals about who will control the flow of listing data in this city by 2027.
Because this isn’t a listings story. It’s a market structure story.
On July 22, inside Extell Development’s Central Park Tower, executives at Compass International Holdings held two sessions — one morning, one afternoon, roughly 200 agents each. The billing was benign: a “Fall Marketing Playbook” launch. The content was not. According to agents in attendance, CIH CEO Robert Reffkin and other brokerage heads suggested brokers temporarily pull their listings off StreetEasy starting in August.
The follow-up email removed any ambiguity. Step one of the playbook: “Delist your listing from StreetEasy.”
What Actually Happened in the Room
The attendee list tells you how much weight was behind this. Sotheby’s International Realty’s Nikki Field. Compass’ Leonard Steinberg. Corcoran president Pam Liebman. Sotheby’s International EVP of sales Marissa Ghesquiere. This was not a regional training session. This was the leadership of Manhattan residential brokerage in one room.
The recommended mechanism matters as much as the ask. The playbook pointed agents toward the Real Estate Board of New York’s “Participant’s Only” designation — a status that shares a listing with other agents through the Residential Listing Service while withholding it from public-facing consumer sites.
Read that again. The listing stays inside the professional network. It disappears from the place buyers actually look.
Agents themselves split on interpretation. Some in attendance framed it squarely as part of Compass’ running fight with Zillow and StreetEasy. Others described a broader informational session about positioning listings, with no specific target.
Steinberg offered the most disarming explanation:
“It’s a case of what the sellers want to do.”
He noted he typically pulls listings off public platforms in August anyway — historically one of the slowest months for selling real estate in the city. That’s a fair point on its own terms. August in Manhattan is genuinely dead. But a seasonal habit practiced by one broker is a different animal from a coordinated playbook distributed to 400 of the most productive agents in the market.
The Counterpunch
StreetEasy did not treat it as seasonal. Their spokesperson:
“When Compass uses their clients’ homes as leverage to benefit their own bottom line, sellers lose exposure, buyers lose access and the brokers who play by the rules get undercut. This is the Compass playbook: pull listings from open platforms, consolidate buyers into their own channels, and call it seller choice. New Yorkers deserve better.”
Compass’ response leaned on fiduciary framing — that agents have a duty to represent clients’ best interests, and that giving sellers choices in how they market their properties helps them hit their individual goals.
Both statements are strategically constructed. Both are also, in their own way, describing the same underlying fact: whoever holds the listings holds the traffic, and whoever holds the traffic holds the economics.
The Numbers That Make This Different
Here is where a normal industry spat becomes a genuine market-structure question.
- 80% — Compass’ estimated Manhattan market share, per an analysis from regulatory publication The Capitol Forum using 2025 RealTrends data
- $1.6 billion — Compass’ January acquisition of Anywhere Real Estate
- ~90,000 — owned-brokerage agents added through that deal
- 280,000 — franchise agents that can contribute listings to Compass’ platform
- ~400 — NYC agents in the two July 22 sessions
The Anywhere acquisition brought Corcoran, Coldwell Banker, Sotheby’s International Realty and Century 21 under one roof. In New York specifically, that means Corcoran, Sotheby’s and Coldwell Banker Warburg. Earlier this month, Compass told Coldwell Banker Warburg agents they’d be folded in entirely, operating as “Warburg at Compass.”
A firm with 80 percent share of a market does not “suggest” things. It sets defaults.
Why New York Is Its Own Battlefield
An important technical distinction that most coverage glosses over: brokerage relationships with StreetEasy and REBNY’s Residential Listing Service are not structurally the same as their relationships with MLSes and Zillow elsewhere.
In most markets, listings syndicate. An agent posts to the MLS, and the MLS feeds the portals. Cut the feed, and the portal goes dark — which is exactly what happened in Chicago.
In New York, most agents input their listings directly onto StreetEasy. There’s no syndication pipe to sever. The only way to pull inventory off StreetEasy is agent-by-agent, listing-by-listing, by hand.
Which explains the room at Central Park Tower. When you can’t cut the pipe, you convene the plumbers.
The Chicago Precedent
Reffkin pointed to Chicago on Compass’ second-quarter earnings call this week as a case study. Traffic to Compass’ own website surged in Q2 there.
The backdrop: for several days in May, Zillow lost nearly half its listings after Midwest Real Estate Data — the local MLS — cut the platform’s data feed. The week prior, Zillow had sued both Compass and MRED, alleging the two conspired to harm Zillow and stifle competition after Compass syndicated all its listings directly to MRED as part of the listing service’s national expansion.
On the same call, Reffkin criticized portals for what he called restrictive rules on how agents can list properties, and predicted that as Compass’ private and “Coming Soon” inventory grows, buyers will simply come to Compass directly. His framing:
“Is it unreasonable to expect that the company that has the most listings in the United States is the number one place people search the United States? I don’t think so.”
That is a coherent strategy stated plainly. It is also, functionally, a bid to become the portal.
The Regulators Are Already Reading
This is the part CRE professionals should track most closely, because it’s where the story stops being about residential.
June 2026 — TRD reported that the antitrust division of the New York Attorney General’s Office was contacting leaders at top NYC brokerages, requesting information as part of a probe into Compass’ market footprint.
July 2026 — Reffkin received a letter from a U.S. House subcommittee focused on antitrust and regulatory issues, requesting a briefing on the MRED partnership and how private listings could affect the housing market.
The conflict itself has a longer arc. Zillow updated its rules in April 2025 to ban listings marketed elsewhere and not uploaded promptly to its platform. Compass sued in June 2025, then dropped the case earlier this year. StreetEasy separately rolled out a policy cutting agent access to StreetEasy Experts, StreetEasy Concierge and Zillow Premier Agent for NYC agents caught marketing listings off-platform.
Everyone has now escalated at least twice.
What This Means If You Operate Here
Four things I’d put on the board:
- Data access is becoming a competitive moat, not a utility. If you underwrite, appraise, or source deals using public listing data, assume that data gets thinner and more expensive.
- Concentration risk is now a New York problem. Eighty percent share in Manhattan is a number that invites regulatory attention regardless of intent.
- “Seller choice” is the frame to watch. It’s legally durable and rhetorically clean. It will be the language of every escalation from here.
- Watch September. August is a defensible test precisely because it’s slow. If delisting persists into the fall market, the seasonal explanation stops holding.
The Bottom Line
The most valuable asset in residential real estate stopped being the buildings a long time ago. It’s the inventory data — who sees it, when, and through whose front door.
Compass spent $1.6 billion assembling the largest collection of agents in American history. It now controls roughly four-fifths of Manhattan. And on July 22, it put 400 of the best agents in the city in one room and handed them a playbook whose first line was an instruction to go dark.
Whether that’s fiduciary duty or market power depends entirely on who you ask — and, increasingly, on what the New York Attorney General concludes.
Watching this one closely. If you’re operating in NYC — brokerage, development, capital markets, or proptech — how are you planning around a market where listing data may no longer be a public good? Drop your read in the comments. I want to hear from people actually pricing deals into this.
