Utah escalated from civil to criminal action, charging Kalshi and two of its co-founders. Separately, Polymarket halted trading after a third-party provider compromise drained user accounts on its international platform. State enforcement risk now reaches individual executives, and vendor risk is a recurring operational exposure.

Utah attorney general files criminal charges against Kalshi and co-founders Tarek Mansour and Luana Lopes Lara
Utah's attorney general filed charges on October 28 alleging the defendants illegally promoted online gambling and allowed an undercover agent to place wagers. A Kalshi spokesperson called the action an overreach and said the company expects to contest it in court, as it did in Arizona. The charging document was not machine-readable in review, so the count breakdown and court are not confirmed here. For compliance teams, state exposure now extends to named executives, not only the entity.

Polymarket suspends trading after third-party provider breach drains user accounts
Polymarket said on October 29 that a third-party provider was compromised, affecting its international platform. CoinDesk reported users with balances saw accounts drained, with DeFi Llama tracking about $2.7 million in losses. Polymarket said it fixed the issue, referred the matter to law enforcement and will compensate affected users. It is the second third-party incident this year after a June front-end breach, so vendor oversight is a live diligence question for operators and their counterparties.
