Polymarket Hits $529M in Betting on Iran Crisis After U.S.-Israel Strikes

Geopolitical tensions in the Middle East have reached a breaking point. Joint U.S.-Israeli airstrikes on Iran killed Supreme Leader Ayatollah Ali Khamenei and other senior officials. The strikes targeted nuclear facilities and military sites in Tehran.

Iran retaliated with missile and drone attacks on U.S. bases and Israeli cities. Casualties mounted quickly, with reports of civilian deaths, including children.

Amid this chaos, prediction market platform Polymarket saw an unprecedented surge in trading volume. It crossed $529 million on Iran-related contracts since December 2025.

Strikes and Leadership Loss

The airstrikes began late on February 28 and continued into March 1. Iranian state media confirmed Khamenei’s death early Sunday. He had ruled since 1989 and was 86 years old.

Reports said his daughter, son-in-law, and grandson also died in the attack. Other senior figures killed included Ali Shamkhani, secretary of the Supreme National Security Council, and IRGC Commander-in-Chief Mohammad Pakpour.

U.S. President Donald Trump called Khamenei “one of the most evil people in history.”

He vowed strikes would continue “throughout the week or as long as necessary” to dismantle Iran’s nuclear program.

Iran responded with missile and drone attacks on U.S. bases in the Gulf and Israeli cities, including Jerusalem. Iranian sources reported over 133 civilians killed in the initial strikes. One attack allegedly hit an elementary school, killing more than 100 girls.

Global leaders condemned the violence. Russian President Vladimir Putin described Khamenei’s killing as a “cynical violation of all norms of human morality.” The escalation followed stalled nuclear talks, ongoing protests in Iran, and rising threats against U.S. interests.

Polymarket Frenzy

As the conflict unfolded, Polymarket became a hub for speculation. The blockchain-based prediction market saw $529 million in volume on Iran-related contracts.

The “U.S. strikes Iran by [date]” series, launched in December 2025, drew massive interest. The February 28 contract alone attracted $89.6 million on the day of the strikes.

Another market, “Khamenei out as Supreme Leader by March 31,” reached $45 million before resolving “Yes” at 100% after his death. It became one of Polymarket’s most traded geopolitical contracts.

Broader Iran-themed markets pushed total volumes to around $600 million. These included bets on ceasefire timelines, regime change, and possible U.S. ground invasions.

Odds of a new supreme leader by March 31 stood at 75%, with $211,917 in volume. Contracts on U.S. forces entering Iran by March 7 were priced at 31%.

These figures surpassed many traditional market volumes for similar events. Polymarket’s appeal lies in its ability to provide real-time speculation and liquidity during global crises.

Concerns and Reactions

The boom raised concerns about insider trading. Analytics firms Bubblemaps and Polysights flagged six anonymous wallets that profited over $1.2 million on precise pre-strike bets.

One wager of $26,513 yielded $174,000. Critics argued that the Khamenei market’s terms, which included death as a qualifying event, could incentivize harmful actions.

Polymarket’s anonymous nature, requiring only a digital wallet, amplifies these risks. The platform insists it harnesses crowd wisdom for accurate forecasts. On X, users echoed the frenzy. One wrote, “Geopolitics has become a liquid asset class.” Another noted record flows and insider concerns.

Defense stocks also reacted. Lockheed Martin and Raytheon rose 2.5%, aligning with Polymarket’s escalation odds. This intersection of war and wagering illustrates a new era where global uncertainties fuel digital economies.

As strikes persist and Iran vows revenge, Polymarket’s markets will likely continue to evolve. This offers a crowdsourced glimpse into an unpredictable future.
