Prediction platform Polymarket has recorded some of the largest trading volumes in its history as traders flock to contracts tied to the escalating U.S.-Iran conflict. A long-running market titled “US strikes Iran by…?” has accumulated $529 million in total volume, placing it among the platform’s biggest contracts ever.
U.S.-Iran Strike Market Becomes One of Largest Political Contracts
The February 28 strike date alone generated nearly $90 million in trading. Contracts required confirmed U.S. drone, missile, or air strikes on Iranian soil to resolve as “yes.” Once military action was confirmed, multiple daily markets closed in favor of traders who had positioned for that exact date.
Another high profile contract, focused on whether Ali Khamenei would leave power by March 31, drew $45 million in volume and resolved at 100% following official confirmation of his death. The speed of price movement highlighted how rapidly geopolitical developments are reflected in blockchain-based prediction markets.

Ceasefire and Regime Change Bets Gain Momentum
Attention has now shifted to ceasefire timelines and regime stability. Traders currently price a majority probability of a ceasefire by late April, while contracts on regime change by midyear trade above 50%.

Onchain analysts identified six wallets that reportedly earned about $1.2 million by correctly betting on the February 28 strike. The activity has intensified debate over whether prediction markets offer transparent forecasting tools or raise concerns about information asymmetry during sensitive geopolitical events.
