According to CoinMeta, JPMorgan Chase intends to secure the underwriting role for Polymarket in the future. In October 2025, JPMorgan Chase notified Polymarket to terminate the cooperation due to regulatory concerns, and subsequently Polymarket transferred its banking business to other institutions. This February, JPMorgan Chase invited Polymarket CEO Shayne Coplan to give a speech at a Miami private banking conference, emphasizing the close and active relationship maintained with JPMorgan Chase in terms of integration across multiple entities, operations, and the substantial handling of customer funds.
