Polymarket bettors now see a 22.5% chance of a U.S. invasion of Iran this year, up from earlier levels, after a report that Israel is preparing for a possible escalation between Washington and Tehran next week. The jump in the prediction market’s “yes” odds reflects growing anxiety over a conflict that has simmered for months but now appears to be entering a new phase.
The 22.5% figure
The bet, which pays out if the U.S. military launches a ground invasion of Iran before the end of 2025, surged to 22.5% late Thursday. That’s a sharp increase from the 10–12% range where it had traded for most of the past month. The move came shortly after a report circulated that Israel’s defense establishment is bracing for the possibility of a U.S.-Iran confrontation as soon as next week.
Prediction markets like Polymarket allow users to buy and sell shares in binary outcomes. The price of a “yes” share represents the market’s implied probability of the event occurring. At 22.5%, the market is pricing in roughly a one-in-five chance of a U.S. invasion.
What the report says
The report, published by a news outlet, quotes unnamed Israeli officials saying the country’s military is on alert for a potential U.S. strike on Iranian nuclear or military facilities. It states that Israel is preparing for the possibility that the U.S. will escalate its actions against Iran next week, though it does not specify what form that escalation might take.
The timing is notable. The report comes amid heightened rhetoric from both Washington and Tehran. The U.S. has repeatedly warned it will not allow Iran to develop nuclear weapons, while Iran has threatened to close the Strait of Hormuz if attacked. The report does not claim that an invasion is imminent, only that Israel is taking the scenario seriously enough to prepare.
A week of potential escalation
Next week could be a critical period. The report’s phrasing — “next week” — gives the market a concrete timeframe. Bettors are now pricing in a significant chance of action within the next seven days, even though the invasion bet covers the entire year. That suggests many traders are treating the report as a leading indicator.
Polymarket’s odds have been volatile in recent months. The U.S.-Iran invasion contract hit a low of 5% in early January after a diplomatic push by European mediators. It climbed back to 15% in February after the U.S. deployed additional naval assets to the Persian Gulf. The latest jump to 22.5% is the highest since the contract launched.
The coming week will test whether those odds hold or shift as new information emerges. No further official statements from the U.S. or Iran have been released, and the report itself is based on anonymous Israeli sources. For now, the market is betting on a tense few days ahead.
