The rise of prediction markets in the United States has ignited a contentious debate over their regulation, particularly as bets on military actions and political events become increasingly prevalent. With platforms like Polymarket and Kalshi facilitating billions in transactions, critics are sounding alarms about potential risks, including insider trading and national security threats.
The Growth of Prediction Markets
In recent months, prediction markets have surged in popularity, amassing over $44 billion in trades. These platforms, which allow users to wager on a broad spectrum of events—from sports outcomes to political elections—have transformed the gambling landscape in the U.S. Traditionally, sports betting was largely prohibited until 2018, while wagering on elections remained illegal until recently. With the legalisation of betting on the 2024 presidential campaign, these platforms have seen a substantial increase in user engagement.
However, a darker side has emerged, with bets related to geopolitical events, particularly involving Iran, Israel, and Venezuela, drawing significant scrutiny. For instance, a recent bet placed by an individual on whether Iran’s Ayatollah Ali Khamenei would be “out” by 1 March highlighted the morally ambiguous nature of such wagering. Critics argue that these markets not only trivialise serious global conflicts but could also encourage unethical behaviour such as insider trading.
Regulatory Challenges and Controversies
Despite existing U.S. regulations prohibiting gambling on matters involving war and terrorism, many prediction market firms have managed to operate without strict oversight. This lack of regulation has led to calls for a crackdown from various advocacy groups. Craig Holman, a lobbyist from the Public Citizen advocacy group, expressed concern over the troubling implications of such bets, stating, “It has turned into this very gruesome type of thing on the death of a head of state.”

Polymarket has reportedly handled over $500 million in bets related to the potential for war with Iran, including markets that previously offered odds on nuclear detonations. Although the company later removed such markets following public backlash, it remains possible to place bets on military intervention timelines. Kalshi, on its part, recently cancelled a market that had attracted $54 million in trades concerning Khamenei, citing prohibitions against markets directly linked to an individual’s death.
The Regulatory Landscape
As the debate intensifies, the regulatory framework governing these prediction markets remains murky. Unlike conventional gambling establishments, where odds are set by the house, prediction market platforms operate akin to stock exchanges, enabling users to bet against one another on the outcomes of future events. This distinction has led the Commodities Futures Trading Commission (CFTC) to claim oversight, although many believe that these platforms are attempting to evade the stricter regulations imposed on traditional gaming firms.
Legal battles are burgeoning as various states assert their right to regulate prediction markets alongside other gambling entities. Even some members of Congress, including Democrats, have introduced legislation to restrict federal officials from trading in event contracts, citing instances of suspicious trading connected to military developments.
The Future of Prediction Markets
Despite the mounting pressure for stricter regulation, the likelihood of significant changes appears slim. The Biden administration’s previous attempts to impose strict regulations on sports and political event contracts faltered following a court defeat. Moreover, the recent CFTC decision to withdraw proposed bans on these contracts signals a shift towards a more permissive regulatory environment. Michael Selig, the Chairman of the CFTC, has defended the legitimacy of event contracts, arguing they provide essential functions for businesses to hedge against risks.

In response to growing scrutiny, platforms like Polymarket and Kalshi are taking steps to enhance transparency and crack down on suspicious activities. Kalshi has recently launched investigations into insider trading incidents and has vowed to clarify its rules regarding markets tied to individual deaths. However, the effectiveness of these measures remains to be seen, as users continue to express dissatisfaction with the firms’ approaches.
As the prediction market landscape continues to evolve, the underlying ethical and regulatory issues will likely remain at the forefront of public discourse.
Why it Matters
The emergence of prediction markets represents a significant shift in the gambling paradigm, where the line between betting and speculative trading becomes increasingly blurred. As these platforms gain traction, the potential for unethical practices and national security risks grows. Striking a balance between innovation and regulation will be crucial in ensuring that these markets operate fairly and do not exploit serious global events for profit. The implications of this debate extend beyond the realm of gambling, touching on fundamental questions about morality, governance, and the responsibilities of market participants.
