Real Estate Platform Stocks Lose $4.6 Billion in a Day: What Happened?

On the 27th, Compass Inc. (NYSE: COMP), a U.S. real estate brokerage platform, closed down 6.96% at $7.09 on the New York Stock Exchange. Amid a surge in trading volume, its market capitalization fell to about $5.26 billion (approximately KRW 7.1 trillion), erasing roughly $340 million (around KRW 460 billion) in a single day.

In January 2026, Compass acquired Anywhere Real Estate through a stock-for-stock exchange, bringing major brands including Coldwell Banker, Century 21 and Sotheby’s International Realty under its umbrella and propelling itself to become the world’s largest residential real estate brokerage. Recently, after conflicts over its “pre-listing” marketing strategy, the company moved to resolve regulatory disputes with online platforms by dropping litigation related to listing exposure rules.

Based in New York, Compass is a tech-driven brokerage offering software-based residential real estate services. Throughout the 2020s, it has grown to become the leading U.S. brokerage by transaction volume. The company has been at the center of various lawsuits and regulatory debates over MLS rules and private listings, and in June 2026 it faces an antitrust trial filed by a Northwestern MLS.
