JPMorgan Chase is weighing a potential underwriting role for Polymarket, despite ending its banking relationship with the prediction-market platform last year over regulatory concerns.
The potential shift highlights how quickly Wall Street’s view of prediction markets is changing. Polymarket has expanded rapidly as demand for event-based contracts grows, while regulators continue to debate whether some of its products resemble financial instruments, gambling, or both.
JPMorgan Reopens the Door
JPMorgan ended its banking relationship with Polymarket in 2025 amid concerns about the legal status of prediction markets. Polymarket had previously faced regulatory action over its operation of unregistered derivatives contracts in the United States.
However, the relationship did not disappear entirely. JPMorgan has continued to interact with Polymarket executives and is now considering a role in a potential public offering, according to recent reporting.
The development comes as Polymarket prepares for a major capital raise. The company is reportedly seeking more than $1 billion at a valuation of roughly $20 billion. An IPO could further strengthen its position in the rapidly expanding prediction-market industry.
Prediction Markets Enter the Mainstream
JPMorgan’s changing stance also reflects broader interest from traditional financial institutions. CEO Jamie Dimon said earlier this year that the bank could eventually offer prediction-market services, although he stressed that JPMorgan would avoid certain categories, including sports and politics.
The bank has simultaneously tightened its approach to employee participation. JPMorgan has warned staff against using confidential or non-public information when trading prediction-market contracts, reflecting growing concerns about conflicts of interest and insider trading.
For Polymarket, potential involvement from a major investment bank would represent a significant validation of its business model. It could also signal that Wall Street increasingly views prediction markets as a financial-services opportunity rather than solely as a regulatory risk.
Still, the industry’s legal future remains uncertain. Regulators and state authorities continue to scrutinize prediction platforms, particularly contracts tied to elections, sports, and other sensitive events. Therefore, JPMorgan’s possible underwriting role would mark a notable reversal, but it would not remove the regulatory challenges facing Polymarket.
