JPMorgan Chase Ends Banking Services to Polymarket in October 2025 Citing Regulatory Uncertainty
TL;DR — JPMorgan Chase stopped banking services for Polymarket in October 2025 over regulatory uncertainty. The parties remain in close contact with the bank seeking an IPO underwriting role as the platform targets a $20B valuation and $1.2B annualized revenue. Polymarket and Kalshi have flagged over 140 insider trading cases this year.
SCCG Take — Regulatory uncertainty is forcing traditional banks to limit exposure, yet Polymarket’s growth metrics and ongoing ties show operational resilience that may accelerate calls for defined federal rules.
JPMorgan Chase ceased providing banking services for Polymarket in October 2025. The bank showed reluctance to continue over growing regulatory uncertainty for the federally licensed event exchange.
The Financial Times reported the change. Despite the end of services, the parties remain in close contact. JPMorgan Chase is seeking the underwriting role for Polymarket’s IPO.
Polymarket is exploring a new financing round that could value it at $20 billion. Annualized revenue has tripled to $1.2 billion.
In a statement to Reuters, Polymarket said: “We maintain a close, active relationship with JPMorgan across multiple entities, operational integrations, and material handling of customer fund flows. The strength of our relationship is highlighted by our CEO speaking at three of their flagship events in the past year alone. Any suggestion otherwise fundamentally mischaracterizes our relationship.”
Polymarket continues helping to flag and root out insider trading. The platform and rival Kalshi flagged more than 140 potential cases since the beginning of the year.
JPMorgan Chase Remains in Close Contact with Polymarket
The termination of banking services has not severed ties. JPMorgan Chase and Polymarket stay connected across operational areas. The bank’s interest in underwriting the IPO reflects this sustained engagement.
Polymarket Growth and Insider Trading Oversight
Revenue has reached $1.2 billion annualized as the company eyes a $20 billion valuation. Its cooperation with Kalshi on more than 140 flagged cases demonstrates active steps to address market integrity during this expansion.

Banks are derisking but not walking away—Polymarket's growth is forcing Wall Street to straddle compliance and opportunity.
We watch this closely because federally licensed prediction markets sit in a regulatory gray zone that scares banks but attracts capital. When a tier-one bank exits services yet chases the IPO, that tells you the sector's too big to ignore and the rule-making window is closing fast.
