New reporting adds detail about the security incident: a compromised third-party provider distributed malicious code that hijacked logged-in sessions and drained more than $2 million from traders, according to SecurityWeek. The Guardian reported that Polymarket paused international trading for about an hour; the supplied coverage says affected users would be made whole. The new reports do not resolve the CFTC inquiry or the separate examination of Israeli election trades.
Update 30 Oct 2026, 2:02 am UTC
The new coverage adds detail about the security breach: a compromised third-party service distributed cryptocurrency-draining code, and reports put the amount traced at about $2.5 million. Polymarket said affected users would be reimbursed; the supplied coverage does not change the unresolved status of the CFTC inquiry or the Israeli election-trade examination.
How it started
The central regulatory issue is whether Polymarket kept US users off its offshore platform as required by a 2022 settlement. The Next Web reported that the Commodity Futures Trading Commission is again examining whether the company broke that agreement, citing reporting based on two people familiar with the matter.
This is not the first examination of US access since that settlement. According to CNBC International, the agency previously investigated the issue in 2024, but dropped those measures in July 2025.
How it unfolded
On October 27, CNBC International reported that Polymarket faced a renewed CFTC investigation over American access to its offshore platform. The issue concerns compliance with the earlier settlement, rather than a newly announced finding of wrongdoing.
On October 28, Japan Times reported that the agency was examining the company's controls for determining customer locations, as well as its advertising activities in the United States.
On October 29, Bloomberg reported a separate investigation by Polymarket into a string of well-timed, profitable trades on the Israeli election that week. The trades raised concerns about potential insider trading. The supplied reports do not establish that those trades prompted the CFTC investigation.
Also on October 29, a security incident interrupted trading. The Block reported a $2.65 million exploit and said Polymarket attributed the incident to a compromised third-party provider. The platform moved into cancel-only mode, allowing existing orders to be canceled while blocking new buy and sell orders, according to The Defiant.
NBC News reported that the international platform's trading halt lasted an hour. Forbes subsequently reported that Polymarket said it would fully reimburse affected users.
Where it stands
The coverage describes three distinct issues: regulatory compliance over US access, suspicious Israeli election trades and a security breach involving an outside provider. It does not establish a connection between the breach and either investigation.
The CFTC inquiry and Polymarket's examination of the election trades remain unresolved in the supplied reporting. Neither report establishes a settlement violation or insider trading.
On the security incident, CNBC International reported that user funds had been stolen by hackers and that the exchange was referring the matter to UK authorities. That report also placed the disruption just days before an expected increase in trading during the US midterm elections.
What to watch
The regulatory question is whether Polymarket's location controls and US advertising complied with its 2022 agreement. Separately, the election-trading investigation has yet to establish whether the profitable trades involved improper access to information.
For users affected by the security incident, the immediate outstanding issue is delivery of the full reimbursement Polymarket promised, according to Forbes. The supplied coverage gives no timetable for completing those payments.
