JPMorgan Chase Ends Banking Relationship With Polymarket

JPMorgan Chase ended its banking relationship with the decentralized prediction market platform Polymarket in late 2025. The bank notified the platform in October 2025 that it needed to secure a different banking partner, citing regulatory concerns. Polymarket has since transitioned to an undisclosed lender.

The termination followed Polymarket's reentry into the U.S. market in late 2025, which was made possible by a loosening of federal rules under the Trump administration. The platform had previously been barred from serving U.S. users in 2022 after paying a $1.4 million settlement to the Commodity Futures Trading Commission for operating an unregistered derivatives trading venue.

Despite the severed banking ties, the relationship between the two entities remains complex. JPMorgan invited Polymarket CEO Shayne Coplan to a private client conference in February 2026 and continues to seek a role in underwriting a potential future initial public offering for the company.
