CFTC Reopens Polymarket Probe Over US User Access

The US Commodity Futures Trading Commission has reopened a review of whether Polymarket broke its 2022 settlement, under which the platform promised to keep Americans off its main offshore site, Reuters reported on Oct. 27, 2026. According to write-ups by Bitcoin.com and Bitcoin Magazine, the probe covers location controls, US advertising and customer onboarding.

Details

In January 2022 the CFTC fined Polymarket $1.4 million for offering unregistered event-based binary options and ordered it to block US users. An earlier CFTC and Justice Department investigation was closed without charges in July 2025, Bloomberg reported. The new review, per Reuters, looks at user geolocation, advertising aimed at Americans, and onboarding on Polymarket's US platform.

A separate criminal case is moving forward: in April 2026 prosecutors charged US soldier Gannon Ken Van Dyke with making about $400,000 on insider bets, allegedly accessing the platform through a VPN with a foreign exit point. Van Dyke has denied the charges; his trial is tentatively set for Dec. 7. The CFTC and Polymarket declined to comment, and a probe does not by itself indicate wrongdoing.

What it means for the market

For prediction markets it is another sign that regulators are checking compliance with past terms while the CFTC weighs a rule treating event contracts as swaps. The outcome is unknown and no charges have been filed. Polymarket's live bitcoin odds are in the "Market pulse" section on the home page.
