JPMorgan ended its banking relationship with prediction market platform Polymarket in late 2025 over regulatory concerns, according to a report by the Financial Times. The decision highlights the ongoing challenges that crypto-adjacent companies face in accessing traditional banking services, even as the prediction market sector experiences explosive growth.
The banking relationship was severed as JPMorgan grew concerned about the regulatory risks associated with Polymarket's operations. Prediction markets occupy a complex regulatory space, and banks have been cautious about providing services to companies that could draw scrutiny from financial regulators.
Why Banks Are Cautious
Banks are subject to strict Know Your Customer and Anti-Money Laundering requirements, and any relationship with a company operating in a regulatory gray area creates compliance risk. For a bank of JPMorgan's size and systemic importance, the reputational and regulatory risks of banking a prediction market platform may have outweighed the commercial benefits.
The decision reflects a broader pattern of traditional financial institutions distancing themselves from crypto-adjacent businesses. Despite the growing mainstream acceptance of cryptocurrencies, many banks remain cautious about providing services to companies whose regulatory status is uncertain.
Polymarket's Growth Despite Banking Challenges
The banking relationship termination has not stopped Polymarket's growth. The prediction market platform has seen trading volume surge, and competitor Kalshi is now in talks to raise $750 million at a $40 billion valuation, signaling that investors see significant potential in the prediction market sector despite the regulatory and banking challenges.
Polymarket has reportedly found alternative banking relationships, allowing it to continue operating. But the JPMorgan decision illustrates the fragility of banking access for companies in the crypto and prediction market space, where a single bank's risk assessment can disrupt operations.
The Broader Banking Access Issue
The Polymarket case is part of a larger pattern of banking access challenges in the crypto industry. Companies across the sector have reported difficulties in obtaining and maintaining banking relationships, with banks citing regulatory uncertainty and compliance costs as reasons for declining or terminating services.
This issue extends beyond prediction markets. Custodia Bank's five-year fight for a Fed master account demonstrates that even crypto-focused banks face barriers to accessing the payment system. The industry has argued that qualified institutions should have clear access to banking infrastructure, but the JPMorgan decision shows that the private banking sector is making its own risk assessments independent of the regulatory debate.
What This Means for Prediction Markets
The banking challenge adds to a growing list of regulatory issues facing prediction markets. The CFTC has been actively engaging with the sector, recently suggesting that platforms should improve their compliance practices. The combination of regulatory scrutiny and banking access difficulties creates a challenging operating environment for prediction market platforms.
Despite these challenges, the sector continues to attract significant investment and user interest. The demand for prediction markets suggests that they are filling a genuine need, and the regulatory and banking challenges are likely to be temporary friction rather than permanent barriers. But for now, companies operating in this space must navigate a complex landscape of regulatory, banking, and compliance risks.
