JPMorgan Ditches Polymarket Over Regulatory Fears

JPMorgan Chase ended its banking relationship with prediction market platform Polymarket last year due to regulatory concerns, according to an anonymous source. The bank severed ties in October 2025, which was revealed amid growing scrutiny of prediction markets in the United States.

Prediction markets have expanded rapidly since the 2024 US presidential election, drawing attention from regulators and lawmakers at both state and federal levels. Platforms like Polymarket allow users to bet on contracts tied to events such as politics, sports, and other real-world outcomes.

Polymarket disputed JPMorgan's characterization of their relationship, stating that they maintain a close and active relationship across multiple entities and integrations. The company cited its CEO's appearances at three major JPMorgan events over the past year as evidence of their ongoing partnership.
