Geopolitical Event Trading on Prediction Markets: Regulatory, Ethical, and Operational Risks Under Scrutiny - Surprise Score

Live News

In the lead-up to and aftermath of the February 2025 U.S.-Israel military strikes against Iran, online prediction markets processed over $1 billion in total wagers on dozens of Iran-related outcomes, ranging from Supreme Leader Ayatollah Ali Khamenei’s ouster to potential Strait of Hormuz closures and U.S. ground troop deployments. Well-timed bets placed just hours prior to the strikes, including one anonymous user who earned $553,000 on a $32,000 wager with pre-strike implied odds of only 17%, have sparked widespread insider trading allegations. Democratic lawmakers have called for formal congressional inquiries, noting former President Donald Trump Jr. holds paid advisory roles at leading platforms Polymarket and Kalshi, and have introduced new legislation banning senior executive and legislative branch officials, as well as their immediate families, from trading on prediction markets. Unregulated offshore Polymarket processed $194 million in wagers on Khamenei’s leadership status, paying out winning bets following his February 28 assassination. U.S.-regulated Kalshi, by contrast, refunded all wagers on the same event to comply with federal rules banning death-linked futures contracts, incurring a $2.2 million loss and facing a pending class-action lawsuit from disgruntled bettors who expected payout for Khamenei’s ouster.

Key Highlights

Core findings from the controversy include four material takeaways for market participants and regulators: First, aggregate wager volume on Iran-related events across prediction markets exceeded $1 billion, with $194 million dedicated exclusively to Khamenei’s leadership status on offshore Polymarket. Blockchain analytics firm Bubblemaps confirmed at least six anonymous traders earned a combined $1.2 million on U.S. strike bets placed hours before military action was publicly announced. Second, existing regulatory gaps allow U.S. users to access unregulated offshore prediction markets via virtual private networks, circumventing longstanding federal rules banning futures contracts tied to assassinations, war, or terrorism. Unregulated offshore operator Polymarket’s leadership has previously publicly cited the platform’s ability to incentivize insiders to release non-public information as a core benefit of its unregulated structure. Third, proposed legislation banning federal employees from using non-public information for prediction market trading has 40 Democratic co-sponsors to date, with an additional Senate bill targeting senior administration and congressional officials and their immediate families. The U.S. Commodity Futures Trading Commission (CFTC), the federal regulator for prediction markets, is set to release updated industry guidance in the coming weeks. Fourth, regulated operator Kalshi’s operational misalignment between public market labeling and hidden settlement rules led to $2.2 million in losses from customer refunds, as well as pending class-action litigation alleging deceptive marketing practices.

Expert Insights

The fast-growing $100 billion+ global prediction market sector, which has expanded rapidly in recent years to cover events from elections to macroeconomic data releases and geopolitical developments, is now at a critical inflection point between unregulated offshore growth and formal federal oversight. The recent Iran trading controversy exposes three core structural risks for the sector: regulatory arbitrage, insider information asymmetry, and ethical misalignment between product design and public norms. For market participants, the proliferation of unregulated offshore platforms creates significant counterparty and compliance risk, as U.S. users accessing these sites via VPN may face future enforcement action as regulators close existing gaps. The current narrow legal definition of insider trading for prediction markets also creates asymmetric information advantages for political and government insiders, eroding market integrity and reducing predictive value for ordinary users, as seen in the outsized risk-adjusted returns from pre-strike wagers. There remains an active policy debate over the tradeoffs of unregulated prediction market activity. Libertarian policy analysts argue that even if insider trading occurs, the resulting real-time market pricing provides more accurate public information on geopolitical and policy events, a public good that offsets corruption risks, as noted by the Cato Institute’s senior policy leadership. Critics counter that allowing wagers on war, assassinations, and human suffering creates unacceptable ethical hazards, alongside corruption risks from government officials profiting off non-public military and policy decisions. Upcoming CFTC guidance is expected to address two key gaps: mandatory disclosure requirements for platform insiders and affiliated political figures, and clearer settlement rules for events involving deaths or acts of war, to reduce operational and legal risk for regulated operators. For market participants, increased regulatory oversight is likely to reduce volatility from ad-hoc rule changes and operational failures, while also limiting access to high-risk event contracts that violate federal guidelines. The sector’s long-term growth trajectory will depend on balancing demand for transparent, predictive event data with regulatory and public expectations around ethical conduct and anti-corruption safeguards.
