For the better part of a year, prediction market platforms have been selling a compelling vision to Wall Street and Washington alike. The pitch is elegant in theory: allow people to wager on real-world events and you get faster, more accurate information than any analyst or algorithm could produce on its own. Then the bombs fell on Iran, and that vision collided violently with reality.
When United States and Israeli strikes hit Iran over the weekend, traders rushed to capitalize on the chaos. What followed was not a demonstration of the market’s predictive power. It was something far messier, and the industry is still cleaning up.
A billion-dollar industry under pressure
The platforms at the center of this story are not fringe operations. Polymarket, backed by investors that include Intercontinental Exchange, the parent company of the New York Stock Exchange, carries a valuation of around nine billion dollars and operates offshore, largely outside the reach of American regulators. Kalshi, regulated by the Commodity Futures Trading Commission, is valued at roughly eleven billion dollars and has struck a partnership with Tradeweb Markets. Together, the two platforms handled tens of billions in combined volume last year alone.
Both offered contracts tied to events in Iran. When Ayatollah Ali Khamenei was killed in the strikes, both platforms faced immediate and intense backlash.
On Polymarket, contracts connected to the timing of the strikes had drawn more than 529 million dollars in volume. Blockchain analysts flagged suspicious activity, pointing to newly created accounts making unusual bets. On Kalshi, a contract tracking whether Khamenei would remain in power had attracted more than fifty million dollars in volume before the situation unraveled.
A carveout that could not hold
Kalshi had attempted to design around the ethical minefield. Its contract included a specific provision: if Khamenei died, positions would resolve at the last traded price before his death rather than paying out as a straightforward win. The platform maintains that it does not offer markets that settle on death, and on regulated American exchanges, contracts tied to war or assassination are broadly considered off-limits.
The provision was put to the test almost immediately. Trading volume surged on Saturday even as reports of the killing were already spreading. Kalshi promoted the contract on social media that morning, then issued clarifications, then halted trading altogether. By that evening, the company’s chief executive pledged publicly to reimburse all fees. Kalshi ultimately went further, covering users’ net losses as well, a move that cost the company roughly 2.2 million dollars.
The gap nobody has closed
The episode laid bare a problem the industry has not solved and regulators have not fixed. The question is not simply whether prediction markets can handle geopolitical events. It is whether they should, and what happens when the underlying event is violence.
Supporters of these platforms argue that geopolitical contracts generate real informational value, that a liquid market with genuine stakes produces faster and more precise signals than traditional intelligence or news coverage. They also point to legitimate hedging use cases, noting that shipping companies and oil traders exposed to Middle East risk can use these contracts to manage exposure in ways conventional insurance cannot match.
Critics argue the logic breaks down when the event being priced is someone’s death. In February, Israeli authorities filed what appear to be the first criminal charges anywhere in the world connecting prediction market bets to classified military intelligence.
Washington moves in
Democratic senators led by Adam Schiff of California had already sent a letter to the head of the Commodity Futures Trading Commission demanding a crackdown on war and assassination contracts. The deadline they set for a response is March 9, a date that now arrives with an actual war as its backdrop.
Senator Chris Murphy said he is drafting legislation targeting what he described as markets where insiders with advance knowledge can manipulate outcomes to their advantage. The industry’s own trade group acknowledged that contracts involving death have no place on American exchanges. Days later, one of its members had to effectively shut down a contract for exactly that reason.
The platforms will not escape this moment without consequences. The only real question now is how deep those consequences run.
