On May 22, 2026, House Committee on Oversight and Government Reform (“Committee”) Chairman James Comer opened an investigation into how users of prediction market platforms potentially are using nonpublic information to engage in insider trading. Chairman Comer has requested documents and information to assess how the platforms verify the identities of domestic and foreign account holders, enforce geographic restrictions, and monitor suspicious trading activity to guard against insider trading.
Background
The Committee’s investigation follows a series of escalating enforcement actions concerning prediction market platforms. For example, in February 2026, the CFTC Division of Enforcement released an advisory reminding market participants of the agency’s authority to pursue misuse of material nonpublic information and other forms of market abuse in prediction markets. We previously wrote about this advisory here:
CFTC Enforcement Division Issues Advisory On Prediction Market Trading Practices).
2 That advisory followed two enforcement actions brought by the CFTC against traders on a U.S. prediction market trading platform. The first involved gubernatorial candidate Kyle Langford, who placed a $200 wager on his own political race through a prediction market. The second involved a former editor of a popular YouTube channel who used material nonpublic information to make “statistically anomalous” trades. Both individuals were fined, required to disgorge profits, and suspended from the platforms for five and two years, respectively. The CFTC utilized these actions to emphasize its full authority to enforce against illegal trading practices on prediction markets.
On April 23, 2026, a federal indictment was unsealed in the Southern District of New York charging a U.S. Army Master Sergeant with unlawful use of confidential government information for personal gain, theft of nonpublic government information, commodities fraud, wire fraud, and making an unlawful monetary transaction.
3 The charges arose from an alleged scheme in which the sergeant used sensitive classified information about “Operation Absolute Resolve,” the U.S. military operation that resulted in the capture of Venezuelan President Nicolás Maduro, to place wagers on a prediction market that generated more than $409,000 in profits. The CFTC simultaneously filed a civil complaint against Van Dyke, marking the first time the agency charged insider trading involving event contracts. On May 27, 2026, the Southern District of New York charged a Google software engineer with using confidential company information to place wagers on Google’s most searched person of 2025.

The Committee’s Investigation
In line with these enforcement actions and priorities, Chairman Comer’s letters to the prediction markets request documents and information related to company safeguards used to ensure compliance with applicable U.S. federal regulations governing prediction market platforms. The document requests include materials relating to the platforms’ identity verification and Know-Your-Customer (“KYC”) policies and procedures, including whether international account holders are subject to the same requirements as U.S.-based account holders; the platforms’ policies and procedures for detecting, investigating, and reporting anomalous or suspicious trading activity; and the platforms’ geographic access restrictions and enforcement mechanisms.
With respect to one prediction market, the Committee expressed particular concern about the regulatory gray area created by the platform’s October 2025 expansion to more than 140 countries, noting that this rapid global expansion raises questions about whether internationally placed event contracts are subject to equivalent identity verification and insider trading prohibitions as domestic event contracts. The Committee further noted that global expansion may have created structural conditions that bad actors, especially individuals with access to national security information, can exploit.
Looking Ahead
While the CFTC has already positioned itself squarely as the regulator of prediction markets, this investigation signals that Congress is prepared to act in this space as well. The Committee’s investigation represents the latest in a rapid succession of federal actions, from the CFTC’s February 2026 advisory, to the Southern District of New York indictment and parallel CFTC civil action in April 2026 and the indictment in May 2026, to this Congressional inquiry. Each of these actions underscores the increasing regulatory and enforcement scrutiny facing prediction market platforms. Prediction markets remain firmly in the spotlight, and market participants and platform operators should expect continued and heightened regulatory attention.
