The burgeoning world of prediction markets, which has seen an astonishing $44 billion in trades over the past year, is now facing heightened scrutiny due to unsettling wagers linked to international conflicts. Critics are calling for stricter regulations as the potential for unethical profiteering and national security risks grows. With the recent introduction of bets on the outcomes of military actions in Iran and other volatile regions, lawmakers and advocacy groups are intensifying their efforts to shut down these controversial platforms.
The Rise of Prediction Markets
In recent times, platforms such as Kalshi and Polymarket have gained remarkable traction, particularly following the legalisation of betting on election outcomes in the United States. The ability to wager on various future events—from election results to monetary policy decisions—has captivated a broad audience. For many users, like Stew, a 35-year-old from Montana who has been involved in betting since downloading the Kalshi app, the appeal lies in the novelty and the diverse range of bets available.
The shift towards prediction markets marks a significant transformation in the gambling landscape, especially since sports betting was largely prohibited until 2018. Users can now place bets on a wide array of questions, including the timing of interest rate cuts by the US central bank and even the return of Jesus Christ. However, the introduction of bets regarding the fates of foreign leaders and potential military actions raises serious ethical questions.
Controversial Bets Generate Outcry
The recent surge in bets tied to military operations, particularly those involving Iran, Venezuela, and Israel, has sparked outrage among critics. Concerns have been raised that such activities may not only contravene existing financial regulations but also pose significant risks to national security. Craig Holman, a lobbyist with Public Citizen, articulated the gravity of the situation, asserting that the possibility of wagering on the death of state leaders has transformed the betting landscape into something “gruesome.”

Polymarket has reportedly facilitated over $500 million in bets related to the conflict in Iran, including a contentious market that allowed users to speculate on the likelihood of nuclear detonation. Although this particular market was withdrawn after it drew significant criticism, other bets, such as those regarding potential US military involvement in Iran, remain active. Kalshi also ultimately cancelled a market related to the ousting of Iran’s Ayatollah Ali Khamenei, which had amassed $54 million in trades, citing regulations that prohibit markets settling on an individual’s death.
Regulatory Challenges and Legislative Response
The burgeoning prediction market sector has spurred a complex debate regarding regulation. Unlike traditional gambling operations, which are subject to stringent state oversight, prediction markets operate more like stock exchanges, allowing users to wager against one another on future events. This distinction has led to a tug-of-war between federal regulators, such as the Commodity Futures Trading Commission (CFTC), and state authorities, each vying for control over the burgeoning industry.
As concerns mount over the legitimacy of these markets, recent legislative efforts have emerged. Democratic lawmakers have introduced bills aimed at barring federal officials from trading event contracts, spotlighting incidents of suspiciously timed bets. For instance, a newcomer to Polymarket made a substantial profit just before the announcement of the capture of Venezuela’s president, raising alarms about potential insider trading practices.
Despite these efforts, the likelihood of comprehensive regulatory reform appears low. The Biden administration’s previous push to ban sports and politics-related event contracts has stalled, particularly after a court ruling and shifting political dynamics following the 2024 elections. The CFTC has even sided with prediction market firms in ongoing legal battles, reinforcing the notion that these platforms serve legitimate economic functions.
Industry Responses and Future Outlook
In response to increasing criticism, both Polymarket and Kalshi have begun implementing measures to enhance regulatory oversight. Polymarket has announced plans to actively investigate suspicious betting activities, while Kalshi, which promotes itself as a “regulated exchange,” has reported taking punitive action against several cases of insider trading.

Despite these steps, discontent remains among users. Stew, who received a refund for his bet on Khamenei’s potential ousting, expressed frustration at the perceived lack of transparency regarding the rules governing these markets. He commented on the semantic debate surrounding the classification of prediction markets, suggesting that despite the terminology used, these activities function fundamentally as betting.
Why it Matters
The rapid evolution of prediction markets represents a significant intersection of gambling, finance, and public policy, raising essential questions about ethical boundaries and regulatory oversight. As these platforms continue to gain popularity, particularly in the context of geopolitical instability, the potential for exploitation and the implications for national security become increasingly pressing. The future of prediction markets hangs in the balance, as regulators, lawmakers, and the public grapple with the moral and economic ramifications of allowing such betting practices to flourish unchecked.
