JPMorgan has shuttered its banking relationship with prediction market platform Polymarket, according to the Financial Times. The move severs a key financial link for the CFTC-regulated exchange, which acquired licensed exchange QCEX in 2025 and operates in the US under a CFTC order of designation. The report did not specify when the relationship ended or cite a reason for the decision.

Losing a major US bank as a correspondent could constrain Polymarket's ability to process dollar deposits and withdrawals, forcing it to rely on smaller or non-US banking partners and raising operational risk for traders.
