An industry’s political climate can be subtly altered by a specific type of letter that shows up in a government agency’s mailroom. That type of letter was addressed to the Commodity Futures Trading Commission in May 2026 by a group of Democratic senators led by Senator Chris Murphy of Connecticut and Representative Jamie Raskin of Maryland.
Without the courteous statutory jargon, their question was straightforward. Why has a foreign-run platform called Polymarket been permitted to host bets on the likelihood of U.S. strikes against Iran or Venezuela by the federal regulator with jurisdiction over derivatives and prediction contracts? What is the agency going to do about it now that a number of those bets seem to have been won by users with suspiciously precise timing?

Prediction market experts had observed a number of occurrences before to the lawmakers, which served as the catalyst for the letter. Polymarket users put abnormally high bets on the exact events that followed in the days preceding previous U.S. military operations in the Middle East and Latin America. The bets weren’t subtle. In a number of instances, the timing of the public statements and the bets were so specific that it was impossible to avoid the question of whether someone had advance information.
Since Polymarket has technically been operating outside of the United States for years and is only accessible to Americans through a combination of cryptocurrency wallets and various forms of off-ramping that exist in a legal gray zone, the platform itself does not require users to identify themselves to American regulators. The lawmakers believe that structure is precisely the issue.
According to the Murphy and Raskin letter, the Commodity Exchange Act gives the CFTC the authority to regulate exactly this kind of activity. The lawmakers claim that prediction contracts pertaining to war, assassinations, or what the letter refers to as “destabilizing events” should never have been permitted in any market that was open to Americans. The signatories believe that Polymarket’s offshore status is more of a fig leaf than a legal reality. In the US, a lot of people use the website.
Capital from the United States enters and exits the markets. When covering elections and international events, American media outlets use Polymarket odds. In actuality, the platform has evolved into a component of the American financial system, functioning without the oversight that any comparable domestic prediction market would encounter, regardless of the technical incorporation structure.
The Democratic argument’s strongest point is the connection to Kalshi. For many years, the CFTC has had direct control over Kalshi, a local prediction market. Offering contracts for elections, wars, and other politically sensitive markets that Polymarket has openly published has been forbidden.
As a result, there is a two-tier structure where American users choose the offshore competitor because of the laxer restrictions, but the regulated American platform is subject to the same regulations that the offshore competitor disregards. It appears that investors don’t think this asymmetry can last. Either Polymarket’s regulations will become more stringent, or Kalshi’s will eventually become less stringent. The Democratic letter advocates for the first result.
The intellectual argument some prediction market advocates have attempted to present is what makes the war-betting topic actually challenging rather than merely obnoxious. Some economists and policy analysts have long maintained that expert panels or intelligence evaluations cannot foretell geopolitical events as accurately as aggregated prediction market pricing. In 2003, following public outcry over betting on terrorism, the Defense Advanced Research Projects Agency famously attempted and then abandoned a Pentagon prediction market.
Since then, scholarly research has continued to make the case for prediction markets as forecasting tools. However, claiming that markets effectively aggregate information is one thing. Allowing an anonymous user to earn millions of dollars by seemingly knowing what the Department of Defense would do before the general public is another. In this type of contract, the distinction between insider trading and forecasting is painfully thin.
According to reports, Senator Murphy is drafting legislation that would expressly forbid wagering on war, the deaths of specific people, and violent results. In its current form, the bill would close the jurisdictional gap that has permitted Polymarket to operate as it does by extending CFTC enforcement authority to offshore-operated platforms that are accessible to Americans. Naturally, it is unclear if the bill will pass the Senate.

Prediction markets have a tiny but loud community of supporters, including some libertarian-leaning Republicans who see market regulations as an overreach. The current Congress is divided, and the legislative schedule is packed. As this develops, it appears to be a policy issue whose technical complexity has kept it out of the mainstream political discourse for years. However, because the underlying events have grown too difficult to ignore, it has suddenly entered the mainstream with exceptional force.
Additionally, there is the more general question of what these marketplaces disclose even in the absence of criminal activity. Polymarket’s Iran strike contracts did not only shift significantly in the hours leading up to the strikes. They moved across a longer time span, suggesting that participants were drawing conclusions ahead of the mainstream media by piecing together public facts, troop movements, diplomatic signals, and official comments.
In a way, prediction markets are meant to accomplish that. Additionally, it is precisely the type of predicting that intelligence agencies try and that regulations pertaining to classified material are intended to prevent, depending on the situation. As these markets expand, it becomes more difficult to distinguish between unlawful disclosure and aggregated public analysis.
Now, the CFTC must decide what stance to adopt. Due in part to disputed legal authority and a lack of practical enforcement instruments, the agency has typically been hesitant to establish jurisdiction over offshore platforms. In a sense, the letter from Murphy and Raskin is an invitation to push those boundaries. Political pressure will likely increase if the CFTC does not take decisive action in response. If it does take action, the ensuing legal proceedings will establish the parameters of prediction market regulation for many years to come.
