JPMorgan Quietly Dropped Polymarket as a Client

Back in October 2025, JPMorgan told Polymarket it needed to find a new bank. The reason given was regulatory concerns and nobody knew until the Financial Times broke it, and Reuters confirmed it this week through its own source.

JPMorgan hasn't said anything publicly. Yet Polymarket spokesperson said they still have a "close, active relationship" with JPMorgan across other parts of the business, and pointed out their CEO Shayne Coplan spoke at three JPMorgan events in the past year, he even got invited to a private banking conference in February 2026, months after the account closure.

JPMorgan cut the actual banking relationship but kept the door open elsewhere, because they still want a shot at underwriting Polymarket's IPO someday.

Why would a bank do this to a company it clearly still wants to work with?

Polymarket's regulatory track record is messy. The CFTC fined them $1.4M back in 2022 and banned them from U.S. customers for operating an unregistered derivatives platform. They spent nearly three years in exile, even while blowing up in popularity during the 2024 election.

Then in 2025 things turned around

• July 2025 — Polymarket bought QCEX, a CFTC-licensed exchange, for $112M. This gave them a legit U.S. entity (QCX LLC / Polymarket US).
• Sept 2025 — CFTC gave them a no-action letter, which Coplan called their "green light" to relaunch in the U.S.
• April 2026 — they went further, asking the CFTC to let U.S. users onto their main crypto-native exchange too.

So Polymarket did the work to get regulatory clearance. But banks make their own risk calls, and recently settled a CFTC enforcement action plus crypto, plus gambling is exactly the profile that makes compliance teams nervous, regardless of what the regulator says today.

And it's not just Polymarket getting side-eye right now:

• NYC Council Speaker Julie Menin is accusing prediction market platforms of predatory marketing toward young traders.
• New York AG sued Kalshi (Polymarket's biggest rival) last month over gambling law violations.
• The CFTC itself opened a fresh inquiry into Polymarket in mid 2026, even though it's the same agency that cleared them to operate.

One more thing, Trump is suing JPMorgan and Jamie Dimon over accounts they closed tied to him after Jan. 6, which JPMorgan has since admitted to. JPMorgan is currently trying to prove to Washington/Trump that they don't unfairly close people's accounts. Then this Polymarket story comes out showing them... closing an account, citing vague "regulatory concerns," with no detailed explanation. this makes JPMorgan's "we don't do that" defense harder to believe, because now there's another example sitting right next to the others. Which makes JPMorgan's current legal defense weaker

Bottom line

Polymarket has spent serious money and time getting legally cleared to operate in the U.S., but that hasn't been enough to keep a major bank comfortable holding the relationship. It's a good example of how regulatory approval and banking access are two totally separate battles for companies in this space.
