JPMorgan Chase, the largest bank in the United States by assets, severed its banking relationship with Polymarket — the blockchain-based prediction market platform — in October 2025, according to a report first published by Cointelegraph. The move, driven by regulatory concerns, marks one of the most high-profile instances of a major Wall Street institution withdrawing financial services from a crypto-adjacent platform, reigniting a debate about the systematic exclusion of digital-asset businesses from conventional banking infrastructure.
What makes the development especially striking is the apparent contradiction embedded within it: while JPMorgan reportedly closed the door on providing Polymarket with everyday banking services, the bank has simultaneously signalled a willingness to serve as an underwriter should the platform pursue an initial public offering. The juxtaposition lays bare a kind of institutional ambivalence that has come to define how traditional finance interacts with the broader crypto and decentralised-finance ecosystem — tolerate the upside, recoil from the operational proximity.
Polymarket operates as a decentralised prediction market, allowing users to place wagers denominated in digital assets on the outcomes of real-world events ranging from elections to macroeconomic data releases. The platform attracted enormous attention during the 2024 United States presidential election cycle, when its prediction markets consistently diverged from traditional polling models and, in many instances, proved more accurate. That visibility brought Polymarket into the mainstream conversation — but it also intensified regulatory scrutiny from bodies concerned about whether prediction markets constituted unlicensed gambling or unregistered securities activity.
The Commodity Futures Trading Commission had previously taken enforcement action against Polymarket in 2022, resulting in a settlement of $1.4 million and an agreement to block United States residents from accessing the platform. Despite that settlement, Polymarket continued to grow its international user base substantially, becoming one of the most-visited decentralised applications globally by trading volume during peak political events. That growth, however, appears to have done little to resolve the underlying compliance ambiguities that make financial institutions nervous about direct association.
JPMorgan's decision to exit the banking relationship reflects a broader pattern of risk-averse behaviour among systemically important financial institutions. Compliance departments at major banks operate under intense scrutiny from regulators including the Office of the Comptroller of the Currency and the Federal Reserve, and the reputational and legal exposure associated with servicing platforms that occupy regulatory grey zones can outweigh commercial opportunity — particularly when those platforms deal in prediction contracts that authorities may classify as gambling instruments or derivatives.
Yet the bank's reported openness to an underwriting role in a hypothetical Polymarket IPO reveals how selectively that caution is applied. Underwriting a public offering is a far more lucrative engagement than providing routine banking services, and it carries a different risk profile — one mediated by prospectus disclosure requirements, securities law compliance, and the institutional protections that come with a listed entity. In short, JPMorgan appears willing to engage with Polymarket once the platform has gone through the regulatory laundering process that a public listing entails. Banking the company in its current, ambiguous form is another matter entirely.
This posture — reject now, reconsider at IPO — is not unique to JPMorgan. Across Wall Street, banks have long applied a two-tier calculus to crypto and crypto-adjacent firms: maintain distance from the operational entity while positioning for fee income at the moment of institutional legitimisation. It is a strategy that preserves optionality without accepting near-term compliance risk, and it has been applied to exchanges, stablecoin issuers, and now prediction market operators alike.
What This Means for the Industry
The debanking of Polymarket by JPMorgan is not merely a bilateral business decision — it is a signal about where the boundaries of acceptable risk remain drawn in the eyes of America's largest financial institutions, even as the regulatory climate around digital assets has nominally warmed in recent years. For platforms operating in grey-zone categories like prediction markets, conventional banking access remains contingent on a level of regulatory clarity that has yet to materialise. Until that clarity arrives — whether through Congressional legislation, new agency guidance, or a landmark court ruling — firms like Polymarket will continue to face the structural disadvantage of building global financial products while denied the basic plumbing of the financial system. The IPO pathway, if Polymarket chooses to pursue it, may ultimately represent not just a capital-raising exercise but the only viable route to institutional banking normalcy.
