JPMorgan Ends Polymarket Banking Ties Citing Regulatory Concerns

JPMorgan Chase (JPM) ended its banking relationship with the prediction market platform Polymarket in late 2025, citing ongoing regulatory concerns. The decision, as reported by the Financial Times, underscores the enduring cautious sentiment among major financial institutions towards nascent, largely unregulated industries.

The Wall Street giant notified Polymarket in October 2025 that it would need to find a new banking partner. Polymarket has since transitioned its accounts to an undisclosed lender. The platform had previously faced a $1.4 million settlement with the U.S. Commodity Futures Trading Commission (CFTC) in 2022 for operating an unregistered derivatives trading venue, which barred it from serving U.S. customers. However, under the Trump administration, the CFTC adopted a more permissive stance, allowing Polymarket to re-enter the U.S. market in late 2025.

Despite the termination of formal banking services, JPMorgan has maintained other commercial ties with Polymarket. Notably, the bank invited Polymarket CEO Shayne Coplan to speak at a private client conference in Miami in February 2026. Furthermore, JPMorgan is reportedly interested in pursuing an underwriting role should Polymarket pursue a future initial public offering (IPO). Polymarket officials have also stated that they continue to maintain a close and active relationship with the bank across multiple entities, operational integrations, and the handling of customer fund flows.

This development reflects the continued cautious approach of mainstream financial institutions toward business models based on crypto and blockchain technology. While prediction markets have experienced significant growth, with notional trading volume exceeding $250 billion in 2026, regulatory uncertainties heighten banks' reluctance to provide services to such platforms. This situation highlights the challenges faced by fast-growing companies in nascent industries when securing essential banking services.

Polymarket and similar prediction market platforms, such as Kalshi, are currently facing legal actions in multiple U.S. states, with allegations of operating illegal sports betting operations. These platforms, however, argue that they function as exchanges facilitating trades between buyers and sellers, rather than as gambling operators. The CFTC also has an ongoing investigation into Polymarket. These legal and regulatory pressures continue to shape the overall landscape of the sector.

Analysts and market observers suggest that JPMorgan's move is a strategic one to manage short-term regulatory risks, while the bank retains its long-term interest in the potential of prediction markets. The bank's pursuit of a potential IPO underwriting role indicates its belief in the investment opportunities within this space. Polymarket's current pursuit of over $1 billion in funding, targeting a valuation of $20 billion, further supports the growth expectations within the sector.
