How Much Money Has Been Bet on the U.S.–Israel–Iran War?

Current Probability of a Ceasefire

Prediction markets currently suggest that the U.S.–Israel–Iran conflict is unlikely to end immediately but could reach a ceasefire within the coming months.

On the prediction platform Polymarket, traders estimate roughly:

- **67%** probability of a ceasefire by June 30 - **62%** probability by May 31

These probabilities are derived from real trading activity where participants buy and sell contracts based on their expectations of geopolitical events.

The market has generated more than **$19 million** in trading volume since launching the ceasefire prediction market.

Prices in prediction markets represent the crowd’s collective probability estimate, meaning a price of **67** cents implies a **67%** chance of that outcome.

Heavy Betting on the Iran Conflict

The war between the United States, Israel, and Iran has triggered massive betting activity across prediction platforms.

According to multiple reports, traders have placed **hundreds of millions of dollars** in wagers related to:

- U.S. strikes on Iran - potential regime change - ceasefire timelines - escalation into a regional war

Overall betting across platforms like Polymarket and Kalshi has exceeded **$255 million** for Iran-related geopolitical outcomes.

Several traders reportedly earned significant profits by predicting the timing of U.S. military strikes against Iranian targets.

Why Traders Don’t Expect an Immediate Ceasefire

Prediction market sentiment currently suggests that a quick ceasefire is unlikely.

Some estimates show only about a **one-in-four** chance of a ceasefire happening within the next month.

This outlook reflects several ongoing developments:

- continued missile exchanges - military operations targeting Iranian infrastructure - Iran’s threat to disrupt oil shipments in the Strait of Hormuz

These signals indicate that both sides still have incentives to continue military pressure.

Iran’s Strategy and Energy Pressure

Iran has signaled that it may continue threatening energy routes if attacks do not stop.

The Strait of Hormuz carries about **20%** of global oil supply, making it one of the most critical energy corridors in the world.

Disruptions in this region can cause:

- spikes in global oil prices - shipping disruptions - economic pressure on major economies

Because of these risks, analysts believe international diplomacy will intensify to prevent prolonged conflict.

Political Signals From Washington

U.S. leadership has sent mixed signals regarding the conflict.

Some U.S. officials have warned that the United States could escalate strikes if Iran threatens global energy supplies.

Others have suggested the war could end sooner if Iran’s military capabilities continue to weaken.

These conflicting signals contribute to volatility in prediction market probabilities.

Why Volume and Probabilities Must Be Read Carefully

Even when **tens or hundreds of millions of dollars** are at stake, prediction markets remain probabilistic tools. A heavily traded contract with a price of **30** cents still implies that, in a large sample of comparable situations, the event would be expected to occur only about **30%** of the time.

Volume can make prices more informative by reducing noise and improving liquidity, but it cannot eliminate uncertainty. Structural drivers of conflict, leadership decisions, and unexpected shocks can all push real‑world outcomes far from market expectations.
