U.S.-invade-Iran contract is the board's most-traded market at $73.8M

Iran contract leads the board by volume

Polymarket’s contract on whether the U.S. will invade Iran is the board’s most-traded market, with $73.8M in volume, according to the supplied market summary. The contract trades at 17 cents with 80 days remaining before its close.

The snapshot, published Oct 13, 2026, at 6:09 AM ET, describes a market vulnerable to price changes as headlines arrive. It does not identify a particular news event behind the current price or provide a history of the contract’s moves.

Supporting source covers a different market

The accompanying source does not independently substantiate the Iran figures. According to picksbyodds.com, a separate contract concerns whether the Eastern Pacific will record more than 6 hurricanes of category 3 or above in 2026, with the listed outcome “Above 6.” Its YES price has moved 65.0 percentage points since the archive began; the site labels that information a research signal, not trading advice.

That distinction limits the conclusions available from the material. The Iran summary establishes the reported price, volume, ranking and time remaining, but the hurricane-market observation provides no evidence about the Iran contract’s trajectory.

What it means for prediction markets

• Volume and price measure different things: The $73.8M turnover establishes the contract’s reported activity, not confidence that an invasion will occur.
• The snapshot is time-sensitive: With 80 days to close and headlines capable of moving the price, 17 cents is a point-in-time reading rather than a settled forecast.
• Resolution details are absent: The supplied material does not define what would qualify as a U.S. invasion of Iran, limiting interpretation of the contract’s terms.
