JPMorgan's Dimon Open to Prediction Markets, but Sets Clear Limits

Jamie Dimon told CBS Evening News anchor Tony Dokoupil on Monday that JPMorgan Chase, the largest bank in the United States, is weighing whether to offer prediction market products to its customers, a move that would push the industry's most powerful mainstream institution into one of finance's most contested new arenas.

"It's possible one day we'll do something like that," Dimon said, speaking about services such as Kalshi and Polymarket, which allow people to make bets on everything from the outcomes of sporting events to elections. His conditions were blunt: "We're not gonna be in sports. We're not gonna be in politics. There's a bunch of stuff we won't do. And obviously, we have strict rules around insider information."

The remarks land as regulators are still writing the rules governing the space. Kalshi is regulated by the Commodity Futures Trading Commission as a designated contract market, while Polymarket operates outside the U.S. regulatory framework. CFTC Chairman Michael Selig, in his inaugural public remarks in January 2026, said the agency would withdraw a 2024 proposed rule that would have prohibited certain event contracts, pledging instead to promulgate "clear rules" to regulate the prediction market industry. On March 12, the CFTC's Division of Market Oversight issued Staff Advisory Letter No. 26-08, and four days later published an advanced notice of proposed rulemaking with public comments due April 30.

The scale of what JPMorgan might be entering is significant. In 2025, designated contract markets certified approximately 1,600 event contracts for listing, up from an average of roughly five per year between 2006 and 2020.

Dimon's insider-trading carve-out will face stress-testing from multiple directions. Federal prosecutors in Manhattan are exploring whether certain lucrative bets placed on prediction markets have violated insider trading and other laws. The chiefs of the securities and commodities fraud unit of the U.S. attorney's office for the Southern District of New York recently met with representatives of Polymarket to discuss how existing laws could be applied to potential misconduct in the fast-growing industry. Kalshi and Polymarket announced new insider trading rules on March 23, 2026, centered on politics and sports, preemptively blocking politicians, athletes, and "other relevant people" from betting on their own campaigns or events.

Congressional pressure is mounting in parallel. Senators Adam Schiff of California and John Curtis of Utah said they will not drop their push to ban sports prediction market contracts, despite the platforms' new self-imposed rules. The senators have introduced legislation that would give states, rather than federal regulators, control over sports betting and casino-style games.

The consumer-protection question Dimon himself raised remains the sharpest one. When Dokoupil asked whether prediction markets are closer to gambling or investing, Dimon said, "I think for the most part, it's more like gambling. But there are areas where you could say, 'No, it's investing.' You are deeply knowledgeable. You're taking the other side of a bet. And you think you know better than the other person."

JPMorgan is also separately reviewing its internal rules to determine whether it should spell out expectations for staff who bet on platforms such as Kalshi and Polymarket. Whether a bank that manages trillions in assets can offer prediction contracts without blurring that line between informed speculation and regulated investing is precisely the question the CFTC, the SEC, and bank regulators have yet to answer.
