Prediction Market Ban: House Oversight Weighs Limits

The prediction market ban debate reached Congress on November 13, after House Oversight Committee staff recommended new limits on federal personnel’s bets. The committee cited concerns about officials using nonpublic information. Options include an outright ban or limits on contracts tied to government business and political outcomes, but no ban has been enacted.

What happened

A November 13 memorandum from House Oversight Committee staff recommended that Congress consider additional restrictions on prediction-market trading by federal personnel. Options include an outright prediction market ban or narrower limits on government-related and political-outcome contracts. The committee’s official release describes recommendations for lawmakers to consider, not a rule already in force.

Chairman James Comer said Congress has a duty to prevent public officials and employees from profiting from nonpublic information and should consider reforms to restore public trust. The committee also recommended information-sharing between prediction-market platforms and regulators, according to the release.

The inquiry began on May 22, 2026, and later expanded to additional platforms. The memo says it yielded nearly 1,700 pages of records and communications and five bipartisan staff briefings. It also discusses how platforms identify and report suspicious trading.

Background and context

The committee memo cites cases illustrating insider-trading concerns. It describes an April 24, 2026, federal indictment alleging that Army Master Sergeant Gannon Ken Van Dyke used classified information about the operation that captured Nicolás Maduro to make more than $409,000 in profits on Polymarket. This is an allegation in an indictment, not a finding of guilt.

A separate case led to a CFTC order. On August 28, 2026, the agency said former White House teleprompter operator Gabriel Perez used advance access to presidential speeches to trade mention-market contracts. The CFTC order required him to disgorge $107,539.02 in profits, pay a $65,000 civil penalty and comply with a three-year trading ban.

According to the committee memo, Commodity Exchange Act provisions already bar federal employees, members of Congress, congressional employees and judicial personnel from using nonpublic information gained through their positions to trade covered commodity contracts. The memo says current insider-trading rules apply to prediction-market contracts. The scope of any additional restriction would depend on the language lawmakers adopt.

A separate bill, H.R. 9367, the Stop Lawmakers From Predicting Act, would bar members of Congress, their spouses and dependent children from trading prediction markets tied to government policy or action, political outcomes, or information learned through congressional service. The Congressional Budget Office posted its cost estimate on October 19, 2026, after the bill was ordered reported on June 24. The bill is distinct from the committee staff’s recommendations concerning federal personnel.

Platform cooperation is also part of the inquiry. The memo says prediction-market platforms initially detected and reported most of the insider-trading incidents it reviewed. Four of five platforms provided substantial documentation or briefings on surveillance controls. Hyperliquid said it did not possess certain requested identity-verification and KYC records.

Market reaction

The supplied reporting does not show that the committee announcement drove crypto prices. Major tokens were lower on November 13, but the figures below are a market snapshot, not evidence that the prediction market ban proposal caused the declines.

Alternative.me classified the Crypto Fear & Greed Index at 20, or “Extreme Fear,” on November 13. The supplied index data does not indicate views on US policy or prediction platforms. The market figures show price changes over the 24 hours before the stated snapshot time; they do not explain the declines.

What to watch next

The next question is whether lawmakers turn the staff recommendations into legislation and how they define the people and contracts covered. The committee memo offers options but does not settle those boundaries.

Further proposals could address regulator coordination, platform reporting and identity checks. The committee recommended information-sharing between platforms and regulators, and its memo describes platform surveillance controls as well as requested identity-verification records that Hyperliquid said it did not possess. H.R. 9367 is a separate proposal with a different stated scope.

The evidence cited by the committee includes an indictment allegation and a CFTC enforcement order involving prediction-market trading. Any legislative response would be a matter for lawmakers to consider alongside existing rules on the use of nonpublic information.
