JPMorgan Chase cut its banking relationship with Polymarket in Oct. 2025, telling the prediction market platform to find a new banking partner over regulatory concerns. The bank has since moved to preserve other parts of the relationship, including maintaining its option to compete for an underwriting role in a Polymarket IPO that would value the company at $20 billion.
a new lender after JPMorgan's exit, though the replacement institution has not been publicly identified. Despite the account closure, Polymarket describes the relationship with JPMorgan as close and active across multiple entities, saying the bank still handles its customer fund flows.
The dual posture—terminating the core banking relationship while staying close enough to compete for IPO fees—reflects the tension large U.S. banks face when dealing with crypto-adjacent platforms. JPMorgan's regulatory concern in Oct. centered on the compliance risk the prediction market carried. That concern was real enough to trigger a formal exit from the deposit relationship. The IPO economics are apparently real enough to keep JPMorgan at the table.
Polymarket is pursuing $1 billion in new funding as part of the process that could lead to a public listing. The $20 billion valuation target would make it one of the largest crypto-adjacent IPOs attempted. Polymarket operates as a decentralized prediction market where users bet on real-world outcomes using crypto, and the platform drew significant attention during the 2024 U.S. election cycle as one of the most-watched political forecasting tools.
Handling customer fund flows is not a marginal function—it sits at the center of how a platform like Polymarket moves money in and out for its users. That JPMorgan retained this role even after pulling the primary banking account suggests the two sides drew a line between deposit-account risk and transaction processing, treating them as separable regulatory exposures.
For JPMorgan, underwriting fees on a $20 billion listing run into the tens of millions of dollars. The bank's decision to keep relations warm rather than execute a clean break tracks with how large financial institutions have historically treated crypto firms during regulatory uncertainty—staying close enough to capture upside while limiting balance-sheet exposure.
Polymarket's situation also illustrates a structural problem for crypto platforms operating in the United States. Mainstream banking access remains conditional, subject to individual institutions deciding that the compliance cost of holding an account outweighs the revenue. When JPMorgan exits, the platform does not lose access to capital markets—it loses a basic checking account, a far more foundational dependency.
The GENIUS Act, signed in 2025, established the federal framework for payment stablecoin issuers but did not directly address prediction markets or the banking access questions platforms like Polymarket face. The CLARITY Act, the market-structure bill defining which digital assets fall under SEC versus CFTC jurisdiction, remains the more relevant pending legislative backdrop for how Polymarket's underlying token economy gets classified. Neither piece of legislation eliminates the discretionary risk decisions banks make when opening or closing accounts for crypto-adjacent businesses.
Polymarket has not disclosed a timeline for the IPO or the $1 billion funding round. The identity of the new banking partner also remains undisclosed. JPMorgan has not made a public statement on the matter.
