According to the publication, representatives from the Attorney General’s antitrust unit have been reaching out to executives at several prominent New York City real estate brokerages, seeking information regarding Compass International Holdings. The AG’s office has not provided any statement on the matter.

The stock has faced significant headwinds throughout 2026. Year-to-date losses now stand at 28%, although shares have appreciated 23% compared to their price twelve months earlier.

Compass International Holdings emerged at the beginning of this year following the completion of the $1.6 billion purchase of Anywhere Real Estate. This consolidation created the nation’s preeminent residential real estate brokerage, representing over 340,000 agents and franchise partners.

Anywhere Real Estate operates well-known brands such as Corcoran, Sotheby’s International Realty, and Coldwell Banker.

An Unusually Swift Transaction

The transaction reached completion in January, merely four months following its September announcement — significantly faster than the nine-month period initially projected by both companies.

This accelerated timeline attracted attention. The Wall Street Journal revealed in January that Gail Slater, leading the Justice Department’s antitrust unit, had intended to initiate a comprehensive review of the transaction to assess potential anticompetitive implications.

However, this extended review was never initiated. Compass and its legal representatives appealed directly to Todd Blanche, then serving as Deputy Attorney General, who concluded that any concerns could be resolved without launching a formal investigation.

Compass also brought in Mike Davis, an attorney connected to President Trump and recognized for his involvement in conservative judicial confirmations, to advocate on their behalf with Blanche’s department.

A representative from Blanche’s office informed the Journal that the department “fulfilled its responsibilities” under antitrust regulations, noting that “nothing prevents the department from pursuing enforcement action later if anticompetitive consequences are discovered.”

Legislative Concerns Emerged Earlier

In December, Senators Elizabeth Warren and Ron Wyden sent correspondence to both Slater and FTC Chair Andrew Ferguson, calling for rigorous examination of the merger.

The legislators cautioned that the consolidation might enable the merged entity to maintain commission rates at “artificially elevated” levels while exercising expanded influence over residential real estate transactions.

Their letter referenced statistics indicating the two organizations already controlled approximately 70% of residential property sales by transaction value in Northern California and over 40% in New York City.

The New York Attorney General’s investigation now poses an additional regulatory challenge for Compass, originating from state-level authorities. Compass has not responded to requests for comment.
