A group of U.S. senators is calling on federal antitrust regulators to investigate Rocket Companies’ recent acquisitions, expressing concerns that the deals could stifle competition and harm consumers in the housing market.
On June 4, 2025, Senators Elizabeth Warren, Bernie Sanders, Cory Booker, Mazie Hirono, and Tina Smith sent a letter to the Department of Justice (DOJ) and the Federal Trade Commission (FTC) questioning why the agencies have not challenged Rocket’s $1.75 billion acquisition of real estate platform Redfin, announced in March. The lawmakers argue that the merger could limit consumer choice and drive up homebuying costs by consolidating key segments of the housing industry.
The senators also raised alarms about Rocket’s planned $9.4 billion acquisition of mortgage servicer Mr. Cooper, announced on March 31. They warn that the resulting vertically integrated entity could dominate the market by combining significant mortgage origination, servicing, and real estate listing capabilities. The combined company would service more than $2.1 trillion in home loans across nearly 10 million clients, representing one in every six U.S. mortgages.
“These deals would combine the second-largest mortgage originator, the largest mortgage servicer, and the third-most-visited real estate brokerage website in the United States, into a massive, vertically integrated conglomerate that may … senators wrote.
The lawmakers expressed concern that Rocket could steer Redfin users toward its own mortgage products, manipulate mortgage rates, and misuse consumer data. They also noted that average home prices are more than … their 2019 levels, and mortgage rates are nearing 7%, exacerbating affordability challenges for buyers.
Despite the senators’ concerns, the DOJ and FTC have not taken action to block the Redfin acquisition. The agencies have stated that they will scrutinize mergers for anticompetitive effects but will not interfere with lawful deals.
Redfin shareholders were scheduled to vote on the merger on June 4. However, the deal has faced legal challenges from investors. A shareholder filed a lawsuit in federal court alleging that Redfin and its board misled investors by omitting critical information from a key proxy statement, including potential conflicts of interest involving Goldman Sachs, which advised on the deal and has a lending relationship with Rocket.
The Mr. Cooper acquisition is expected to close in the fourth quarter of 2025, pending regulatory and shareholder approval. Under the terms of the agreement, Mr. Cooper shareholders will receive 11 Rocket shares for each of their own, representing a 35% premium over the 30-day volume-weighted average price of Mr. Cooper’s stock. Upon completion, Rocket shareholders will own approximately 75% of the combined company, while Mr. Cooper shareholders will own about 25%.
Rocket Companies, based in Detroit, has been aggressively expanding its footprint in the housing market. The company aims to create a seamless, all-in-one homebuying experience by integrating real estate listings, mortgage origination, and loan servicing. CEO Varun Krishna has emphasized the importance of using data and AI to deliver personalized products and services to clients.
Critics argue that such consolidation could reduce competition and innovation in the housing industry. They urge regulators to closely examine the potential impacts on consumers, particularly in a market already strained by high prices and limited inventory.
As the housing market continues to evolve, the outcome of these mergers and the regulatory response will have significant implications for homebuyers, sellers, and the broader real estate ecosystem.
