CFTC reopens probe into Polymarket's U.S. user access controls

The U.S. Commodity Futures Trading Commission (CFTC) has renewed its investigation into whether prediction market platform Polymarket violated a 2022 settlement requiring it to block U.S. users from its main offshore platform.

According to a Reuters report published October 27, the agency is examining Polymarket’s geolocation controls, U.S. advertising activity, and procedures for onboarding customers to its newer American platform. The investigation forms part of a broader inquiry that began earlier in 2026.

The renewed scrutiny comes after the CFTC and U.S. Department of Justice closed earlier investigations in 2025 without bringing charges. Neither Polymarket nor the CFTC commented on the latest probe.

The investigation does not establish that Polymarket violated the settlement. Instead, it raises fresh questions about how effectively the company restricts access to its offshore markets while expanding its regulated U.S. operations.

What the CFTC is investigating

The agency is reportedly examining whether Polymarket took sufficient steps to prevent U.S. residents from accessing its offshore platform.

The review covers three main areas:

• Geolocation controls: Whether Polymarket can reliably identify users located in the United States and prevent restricted access.
• U.S. advertising: Whether the company’s promotional activities in the country raise compliance concerns.
• Customer onboarding: Whether the procedures and protections on its newer U.S. platform meet the relevant regulatory requirements.

Polymarket says it prohibits users from employing virtual private networks (VPNs) or similar tools to bypass geographic restrictions. The company has also said it uses monitoring systems to detect misconduct and restrict access to its offshore platform.

However, the effectiveness of those measures is now part of the broader regulatory scrutiny. The investigation’s findings have not been made public, and the reported areas of focus should not be treated as proof of wrongdoing.

Why the 2022 settlement matters

The latest inquiry traces back to a January 2022 agreement between Polymarket and the CFTC.

At the time, the regulator alleged that the platform had offered event-based binary options contracts without the required registration. The settlement required Polymarket to pay a $1.4 million penalty, wind down non-compliant markets, and stop offering access to markets that did not comply with U.S. law.

The agreement also required the company to prevent U.S. users from accessing its non-compliant offshore markets. That commitment became a focal point in 2024, when trading around the U.S. presidential election renewed questions about whether American users could circumvent the restrictions.

The CFTC and Justice Department subsequently investigated whether users were accessing the platform through VPNs or other methods. Those investigations were closed in 2025 without charges, according to reports at the time.

The new inquiry revisits compliance with the earlier agreement while also examining Polymarket’s current operations. It remains unclear what evidence prompted the latest review or whether it will lead to enforcement action.

Polymarket's U.S. expansion adds another layer

Polymarket has also expanded its domestic presence. After acquiring a CFTC-licensed derivatives exchange in 2025, the company began rolling out a U.S. platform late that year.

The offshore and U.S. operations face different regulatory considerations. The offshore platform is subject to the restrictions tied to the 2022 settlement, while a registered U.S. venue must follow applicable rules for customer protection, market oversight, and preventing abusive trading.

The CFTC is reportedly examining onboarding processes and customer protections on the American platform as part of the broader inquiry. That does not mean the regulated platform has breached any rules, but it places the company’s domestic expansion within the regulator’s current review.

Polymarket’s challenge is to grow its U.S. business while maintaining clear separation between permitted domestic activity and access to markets that remain restricted.

Prediction markets face growing regulatory attention

The renewed investigation comes as prediction markets attract more users and scrutiny over how they handle location restrictions, suspicious trading, and potentially sensitive information.

In April 2026, U.S. authorities charged an American soldier over alleged insider trading on Polymarket’s offshore platform. Prosecutors alleged that he used confidential information to place profitable bets. The allegations are separate from the current CFTC inquiry and should not be taken as evidence that Polymarket itself violated the 2022 settlement.

The broader debate also extends to how regulators should oversee blockchain-based trading infrastructure and the operators offering financial products through it. Altcoin Buzz previously covered Hyperliquid founder Jeff Yan’s argument that U.S. rules should target market deployers rather than the underlying chain. Although prediction markets and perpetual futures are different products, both cases illustrate the regulatory questions that arise when crypto infrastructure supports trading activity across jurisdictions.

For Polymarket, the immediate issue is whether its controls meet the obligations attached to its offshore operations and whether its U.S. platform satisfies the requirements applicable to a regulated venue.

What happens next?

The CFTC has not publicly detailed the evidence behind the renewed inquiry, and no enforcement action has been announced in connection with the reported investigation.

Key questions remain unanswered: whether regulators identified specific instances of U.S. users accessing restricted markets, whether the company’s advertising or onboarding practices breached any requirements, and whether the review will result in formal charges or conclude without action.

Until more information emerges, the investigation is best understood as renewed regulatory scrutiny rather than a finding against Polymarket. Its outcome could nevertheless provide a clearer indication of how closely U.S. authorities intend to monitor prediction market platforms as the sector grows.
