The probability that Iran will take military action against a Gulf State on July 12 jumped sharply by 68.0 percentage points in the last 24 hours, rising from 9.5% to 77.5% on Polymarket. This dramatic repricing reflects a sudden and significant shift in market sentiment around this geopolitical event.
Trading volume over the past day reached $63K, indicating active participation in the market. Notably, whale activity aligned with the price move, with large traders adding net $0 into YES contracts, reinforcing the upward momentum rather than contradicting it. This coordination between whale flow and price movement suggests confidence behind the surge.
Such a steep increase in the market-implied probability signals heightened expectations that Iran will engage militarily in the Gulf region on the specified date. The combined price action and whale buying indicate the market is rapidly adjusting to new information or developments, making this contract a focal point for tracking geopolitical risk in the area.
