WASHINGTON, D.C. — April 8, 2026 — A coalition of House Democrats led by Representatives Seth Moulton (MA-06) and Jim McGovern (MA-02) has formally demanded the Commodity Futures Trading Commission (CFTC) explain its failure to act against offshore prediction market platforms allowing bets on U.S. military operations, raising urgent concerns about potential insider trading and the moral implications of wagering on war outcomes.

The lawmakers sent a letter late Monday to CFTC Chairman Michael Selig questioning why the agency has not enforced existing regulations against platforms like Polymarket that facilitate bets on military actions, including the recent U.S.-Israeli attack on Iran and the ouster of Venezuelan President Nicolás Maduro. The letter, obtained first by CNBC, represents the most direct congressional challenge to date over prediction market oversight of war-related contracts.

The Core Regulatory Challenge

The House Democrats argue that CFTC Rule 40.11 explicitly prohibits the listing of contracts that “involve, relate, or reference terrorism, assassination, war, gaming, or an activity that is unlawful under any State or Federal Law.” They contend the Commission has clear authority under section 2(i) of the Commodity Exchange Act to pursue offshore violators when those swap activities have “a direct and significant connection to U.S. commerce.”

“Recent high-profile instances of alleged insider trading on prediction market platforms relating to U.S. government actions — including the military’s intervention in Venezuela and our recent attack on Iran — have fueled concern that the CFTC does not have adequate control over these fast-growing markets,” wrote the lawmakers, who also include Representatives Greg Casar (TX-35), Jamie Raskin (MD-08), Dina Titus (NV-01), Gabe Amo (RI-01), and Yassamin Ansari (AZ-03).

Moral and Legal Implications

Congressman Moulton delivered a stark moral condemnation: “It is morally corrupt and completely unacceptable for these platforms to allow people to bet on whether American service members live or die. This is not a game. The CFTC has the authority to stop this, and we want to know why it hasn’t.”

Congressman McGovern echoed these concerns: “There is something deeply sick about turning war into a gambling opportunity. We’re talking about people betting on bombings, bloodshed, and military action as if human lives are just numbers on a screen. These are not harmless wagers. They raise serious moral and legal concerns, especially when people may be trading on inside information about U.S. military operations.”

Insider Trading Concerns and Political Connections

The letter specifically questions whether the CFTC has been made aware of “any conflicts of interest between major market participants and family members of Executive Branch officials, including the President of the United States.” This reference points to Donald Trump Jr., who serves as both an investor and unpaid advisor to Polymarket, as well as a strategic advisor to Kalshi, another prediction market platform.

The Trump family’s social media company announced last year it would launch its own prediction market platform called Truth Predict, adding another layer of political complexity to the regulatory landscape.

Industry Response and Self-Regulation

Kalshi, which is based in the U.S. and regulated by the CFTC, states it bans controversial bets on topics like war. Polymarket, an offshore company available in the U.S. on a limited basis, has been the venue for headline-grabbing event contracts. Both companies recently announced self-imposed guardrails to curb insider trading on their platforms, but lawmakers argue these voluntary measures are insufficient.

Last week, Congressman Moulton condemned a Polymarket page that allowed users to bet on the rescue of downed U.S. airmen in Iran, after which Polymarket removed the market. Moulton also instituted a ban on prediction market participation by his congressional staff, believed to be the first such policy in Congress.

Broader Congressional Push

The letter represents part of a broader congressional effort to rein in prediction market platforms. Lawmakers have introduced a flurry of bills in recent weeks addressing the threat of insider trading and seeking to ban certain kinds of event contracts, including on sports, government actions, and war.

Last week, more than 40 members of Congress signed a separate letter to the CFTC and the Office of Government Ethics urging guidance to prevent federal employees from profiting off insider knowledge in prediction markets. In February, a group of Democratic senators sent Selig a separate letter expressing concern about event contracts “that incentivize physical injury or death.”

CFTC’s Regulatory Stance

CFTC Chairman Michael Selig has taken an aggressive stance against state-level regulation of prediction markets, arguing that authority belongs to the federal government. The CFTC last week sued three states — Arizona, Illinois, and Connecticut — that had issued cease and desist orders to prediction markets they said violated gambling laws.

On Monday, a federal appeals court in New Jersey ruled that gaming regulators cannot bar the use of Kalshi to place bets on sporting events, reinforcing federal regulatory primacy. “What we’re seeing is an attempt by the state gaming commissions to effectively nullify federal law,” Selig said Monday on CNBC’s “Squawk Box.”

Timeline and Next Steps

The lawmakers have requested a response from Chairman Selig by April 15. “Such corrupt trades deserve swift and decisive oversight. Allowing these contracts to persist raises troubling concerns about the Commission’s desire and capacity to fulfill a global regulatory role,” they wrote.

The CFTC and Polymarket did not immediately respond to requests for comment Tuesday, setting the stage for a potentially contentious regulatory showdown that could reshape the future of prediction markets and their relationship with national security concerns.

Key Takeaways

• House Democrats demand CFTC action against offshore prediction markets allowing bets on U.S. military operations
• CFTC Rule 40.11 explicitly prohibits war-related contracts, but enforcement has been lacking
• Insider trading concerns heightened by well-timed bets on Venezuela intervention and Iran attack
• Political connections include Donald Trump Jr.’s advisory roles with both Polymarket and Kalshi
• Broader congressional push includes multiple bills and staff participation bans
• CFTC maintains federal primacy while suing states over prediction market regulation
• April 15 deadline set for CFTC response to congressional inquiry

The confrontation between Congress and the CFTC over war betting markets represents a critical test of regulatory authority in an era where financial innovation increasingly intersects with national security and ethical boundaries.
