JPMorgan drops Polymarket after Dimon floated prediction bet

JPMorgan Chase has reportedly closed Polymarket’s bank account over regulatory concerns. This comes months after chief executive Jamie Dimon said the bank might one day sell prediction-market products of its own.

This contrast points to an emerging issue for Wall Street. Banks recognize that they can make money with the prediction market, where individuals invest in events like elections, sporting events, and others using real money. But entering a market like this implies taking on some legal risks. JPMorgan seems to want none of Polymarket’s involvement, even if the CEO has thought about doing so himself.

A CEO who was curious, then cautious

Dimon conveyed on the CBS Evening News to Tony Dokoupil late in March that it was “possible one day” to offer prediction market services at JPMorgan. He, however, clarified that the bank would not engage in predicting events in sports or politics and would keep “strict rules around insider information.”

When questioned on whether prediction markets represented gambling or investing, Dimon asserted that most customers saw it as “more like gambling.”

Essentially, both points of view are now found within the same financial institution. Closing the account at Polymarket while keeping the possibility of developing an in-house version of the same product demonstrates which side has won out in terms of compliance considerations.

Washington turns up the heat

Polymarket is facing increasing pressure in Washington too. On May 22, House Oversight Committee Chairman James Comer launched an investigation regarding possible insider trading on Polymarket and its competitor Kalshi. He has sent notices to Polymarket CEO Shayne Coplan and Kalshi CEO Tarek Mansour asking how each of the platforms checks account holders, what geographic limitations are imposed, and how they set alerts in case of any unusual betting.

The letters from Comer mentioned a New York Times report that revealed over 80 Polymarket accounts involved in making bets with questionable timing. Several wagers happened within hours before the US and Israeli military action against Iran was made public.

He also mentioned a federal indictment made public on April 24 that charges US Army Master Sergeant Gannon Ken Van Dyke with using classified information from the operation that seized Venezuelan President Nicolás Maduro to place bets that made over $409,000.

Comer wrote, “This growing pattern of insider trading activity on prediction market platforms indicates that Congressional action may be necessary.”

From the perspective of a lender that is unwilling to accept risks, this is exactly the type of headline that is better avoided.

Predatory-marketing allegations add to the pile

Concerns about insider trading are not Polymarket’s only regulatory challenge. As reported earlier by Cryptopolitan, a council has launched an investigation into claims that the platform has utilized predatory ways to market to young traders.

In summary, these external pressures account for JPMorgan’s preference to pull back rather than financially support Polymarket despite the industry’s promising prospects. JPMorgan is not ruling out prediction markets altogether. It is just distancing itself from a company that entails significant regulatory and reputational risks.

What to watch next

The immediate question is whether other major banks follow JPMorgan out the door and whether Polymarket can secure banking services elsewhere while the Oversight Committee investigation continues.

Comer has asked Coplan and Mansour for documents detailing how their platforms police accounts and geographic restrictions. Their responses could help determine how far Congress takes its scrutiny.

Dimon’s “possible one day” also remains significant. If JPMorgan eventually launches its own prediction-market product, it is likely to be built on the bank’s terms, with tighter controls and far less exposure to the sports and political betting that has attracted regulatory attention.
