The prediction market industry witnessed its most successful month ever in March 2026, with leading platforms Polymarket and Kalshi recording visitor numbers that eclipsed even their 2024 presidential election peaks.
Data from Similarweb indicates Polymarket attracted 45.3 million combined desktop and mobile visitors during March. This marks approximately a 13% jump from the 40 million visits captured in November 2024.
Meanwhile, Kalshi experienced even more dramatic proportional growth. The platform welcomed 13 million visitors in March, representing nearly twice the 7.1 million recorded during November 2024.
Geopolitical Markets Fuel Explosive Growth
The unprecedented traffic spike stems primarily from betting markets centered on the Iran conflict. These geopolitical wagering opportunities have attracted substantial attention from users seeking to speculate on international developments.
On a year-over-year basis, Polymarket’s monthly visitor count has skyrocketed by approximately 400%. Kalshi has experienced similar momentum, with traffic increasing roughly 320% compared to the previous year.
While monthly figures reached new heights, the single-day traffic record remains with Election Day 2024. On that date, Polymarket attracted 8.4 million visitors, while Kalshi drew 1.9 million users.
Following the 2024 electoral contest, both platforms experienced steep declines in user engagement. However, traffic rebounded dramatically in early 2026 as tensions surrounding Iran intensified.
The explosion in Iran-focused betting activity has generated significant ethical concerns. According to reporting by the New York Times, substantial wagers appeared on Polymarket just one day before coordinated U.S. and Israeli military operations against Iran commenced on February 28.
Numerous bets valued at $1,000 or more correctly anticipated U.S. strikes within 24 hours. This suspicious timing prompted speculation about potential insider information among certain platform users.
Polymarket declined to provide comments to the Times regarding these allegations. However, the platform defended its Middle East conflict forecasts on its website as “particularly invaluable in gut-wrenching times.”
Regulatory Challenges and Platform Responses
Kalshi took decisive action by suspending a high-profile market titled “Ali Khamenei out as Supreme Leader?” after wagering exceeded $54 million. The platform withheld payouts, citing its prohibition against markets “directly tied to death,” as reported by the Washington Post.
Operating under Commodity Futures Trading Commission oversight, Kalshi faces explicit restrictions prohibiting trading on war-related outcomes and mortality. Elisabeth Diana, the platform’s communications director, emphasized to the Times that profiting from death is “not allowed on Kalshi, and that’s a good thing.”
Despite these restrictions, Kalshi continues offering Iran-related speculation opportunities, including markets focused on potential U.S.-Iran nuclear agreements.
Polymarket encountered additional criticism recently for hosting a market allowing users to predict when authorities would locate a missing American pilot whose aircraft was downed over Iran. Representative Seth Moulton publicly condemned the market as “DISGUSTING” via social media platform X.
In response, Polymarket announced it “took this market down immediately,” acknowledging the offering “should not have been posted” and failed to “meet our integrity standards.”
Operating predominantly outside U.S. jurisdiction, Polymarket avoids the CFTC regulatory framework governing Kalshi. The platform maintains multiple active Iran conflict markets, including speculation on potential U.S. ground troop deployment and conflict duration. Each market features disclaimers characterizing the platform’s prediction capabilities as “invaluable.”
