Coin Exchange Leader Faces Regulatory Setbacks... 3 Trillion Won in Market Cap Vanished in a Day

Coinbase Global, Inc. (NASDAQ: COIN) plummeted 6.19% on February 3, closing at $168.60 on the Nasdaq. Its market capitalization shrank to about $38.4 billion (KRW 52 trillion), erasing roughly $2.2 billion (KRW 3 trillion) in value in a single day. Trading volume reached 10.14 million shares, underscoring heightened volatility.

Investor confidence has been severely rattled by a civil lawsuit and a cease-and-desist order filed by Nevada regulators, who claim that Coinbase’s sports-event–based prediction market constitutes unlicensed sports betting, coupled with revelations of a customer data leak by an insider. Coinbase is scheduled to report its fourth-quarter and full-year 2025 earnings after the close on February 12, with regulatory developments and any guidance updates poised to shape the stock’s trajectory.

As the largest crypto exchange in the U.S., Coinbase’s financial results and share price remain highly sensitive to cryptocurrency prices and trading volumes. Since its IPO, the firm has diversified beyond trading fees into staking, subscription services, derivatives and prediction markets, yet regulatory uncertainty surrounding digital assets in the U.S. continues to be its biggest risk.
