JPMorgan Chase & CoJPMorgan ended banking relationship with Polymarket over regulatory concerns, but maintains other connections.

J.P. Morgan Chase ended its banking relationship with prediction-market operator Polymarket in October 2025 because of regulatory concerns, according to people familiar with the matter cited by the Financial Times. Polymarket subsequently moved to another bank, whose identity wasn’t disclosed. At the time, the platform was barred from serving U.S. customers following a 2022 Commodity Futures Trading Commission enforcement action over its operation of an unregistered derivatives exchange. The CFTC allowed New York-based Polymarket to resume U.S. operations in 2025 under the Trump administration, although the regulator reportedly continues to investigate the company. J.P. Morgan has maintained other connections with Polymarket, and Chief Executive Shayne Coplan appeared at a February conference for the bank’s private clients. Polymarket said it continues to work closely with J.P. Morgan through other entities, operating arrangements and customer-fund services, while J.P. Morgan declined to comment to Bloomberg News. Prediction markets have faced growing scrutiny from federal and state authorities, with more than a dozen states pursuing legal action against Polymarket and rival Kalshi, alleging that their platforms amount to illegal sports betting. Concerns about insider trading have added to the pressure, as a U.S. soldier involved in planning the January operation to capture Venezuelan leader Nicolás Maduro was charged with using confidential information to earn more than $400,000 through Polymarket wagers. Despite those risks, the industry continues to expand, with prediction platforms generating more than $250 billion in notional trading volume during 2026, according to user-compiled data from crypto analytics service Dune.
