Intelligence Brief
JPMorgan ended a banking relationship with Polymarket in October 2025 over regulatory concerns, adding another point of friction between the prediction market and traditional financial institutions.
The separation was not complete. Polymarket said it continues to work with JPMorgan through other entities, including operational integrations and customer fund flows.
The disclosure comes as Polymarket seeks fresh capital at a reported valuation above $20 billion. The company entered early discussions this month to raise roughly $1 billion, after reportedly securing $1 billion at a $15 billion valuation in April. That earlier round included a $600 million investment from Intercontinental Exchange.
Polymarket’s annualised revenue surpassed $1 billion in June, according to Reuters. Investor demand is rising even as regulatory scrutiny follows the platform into several US jurisdictions.
Strategic Assessment
Polymarket now faces a clear split between capital markets and regulatory risk.
Investors are assigning increasingly large valuations to prediction markets because trading activity has turned the sector into a sizeable financial business. Banks have a different calculation. Exposure to uncertain gambling laws, state enforcement and market integrity cases creates compliance costs that can outweigh the commercial upside.
That tension matters as Polymarket expands. Losing one banking relationship does not cripple the company, particularly while other JPMorgan connections remain active. Repeated restrictions from financial institutions would be more serious. Payment access and banking relationships are basic infrastructure for scaling a platform handling billions of dollars in activity.
The winners are competitors with cleaner regulatory access. The exposed parties are Polymarket and other prediction markets operating between federal derivatives rules and state gambling laws.
Evidence & Method
A source familiar with the matter said JPMorgan ended the banking relationship in October 2025 because of regulatory concerns.
Polymarket disputed the idea that JPMorgan had cut all ties, saying relationships remain active through several entities.
Separately, New York City Council Speaker Julie Menin opened an investigation on Aug. 11 into Polymarket and other prediction platforms over allegations involving marketing practices. The Council requested information concerning influencers, social media activity and advertising.
Polymarket has also been involved in litigation over whether state gambling restrictions can apply to prediction markets regulated at the federal level.
Risk Signals
Polymarket’s valuation assumes that rapid trading growth can survive regulatory pressure.
That assumption could weaken if state restrictions spread, banking access contracts or federal authorities impose tighter rules on event contracts. Market integrity is another risk after the CFTC accused a Google employee in May of using confidential information to make approximately $1.2 million through Google related contracts on Polymarket.
The opposing case is straightforward. Clear federal jurisdiction could remove much of this uncertainty and make prediction markets easier for banks and institutions to support.
