Democratic lawmakers in the United States are advancing legislation to restrict war-related speculation on prediction markets, driven by concerns about insider trading and the ethics of profiting from armed conflict. Senator Chris Murphy and Representative Greg Casar have introduced the Banning Event Trading on Sensitive Operations and Federal Functions Act, known as the BETS OFF Act, which would prohibit prediction market contracts tied to war, terrorism, assassinations, and other sensitive government actions where insiders could possess advance knowledge or influence outcomes.
The proposal arrives in the wake of unusual betting activity on platforms like Polymarket, where contracts appeared to anticipate US military strikes in Iran and Venezuela. Lawmakers argue these wagers suggest access to confidential intelligence, raising serious questions about market integrity. Compounding these concerns, journalists covering sensitive geopolitical events have faced harassment from users attempting to influence contract resolutions, as seen when Polymarket participants pressured an Israeli military reporter to alter wording that would determine payout on a high-value market regarding Iranian missile impacts.
The BETS OFF Act represents one of several Democratic efforts to bring prediction markets under tighter oversight. It complements the DEATH BETS Act, which targets markets focused on war, terrorism, and individual deaths, and builds on earlier proposals from Representative Ritchie Torres and Senators Jeff Merkley and Amy Klobuchar aimed at preventing public officials from leveraging nonpublic information in speculative markets. The legislation would not only bar individuals with insider knowledge from trading on sensitive events but also prevent regulators from approving such contracts in the first place. Some analyses suggest the bill’s scope could extend beyond conflict-related topics to include any event with a predetermined outcome known to insiders, such as entertainment awards or sports halftime shows.
For crypto-native prediction platforms like Polymarket and Kalshi, the regulatory landscape is becoming increasingly complex. These platforms already operate under a patchwork of global enforcement actions. Argentina recently ordered a nationwide block on Polymarket, classifying it as unlicensed gambling, while Arizona has filed criminal charges against Kalshi over election-related betting. Even if the BETS OFF Act does not advance quickly in a Congress controlled by Republicans, its introduction signals growing bipartisan discomfort with markets that allow speculation on war, death, or sensitive state functions. This political momentum strengthens the case for regulators to deny, limit, or geofence such contracts, particularly for US users.
The practical implications for crypto users and platforms are clear. Compliant venues are likely to delist war-related markets for US participants, implement stricter know-your-customer protocols around politically sensitive contracts, and increase monitoring for traders who may possess or exploit nonpublic government information. For users, this means assuming that edgy or conflict-themed markets carry elevated legal and platform-level risk. The broader message is that prediction markets, while innovative, cannot operate in a regulatory vacuum when they intersect with national security, public ethics, and the potential for real-world harm.
In conclusion, the Democratic push to restrict war betting on prediction markets reflects a convergence of concerns about insider trading, corruption, and the moral implications of monetizing violence. Whether or not these bills become law in the near term, they add significant political pressure on regulators and courts already scrutinizing crypto-based prediction platforms. As the technology evolves, the industry must navigate a delicate balance between innovation and responsibility, particularly when contracts touch on war, elections, or other decisions that shape public life. The direction of travel points toward tighter rules, more precise geofencing, and a narrower scope for the most sensitive markets. The question is not whether regulation will come, but how thoughtfully the industry can engage with policymakers to shape frameworks that protect integrity without stifling legitimate innovation.
