The probability of Iran taking military action against a Gulf State on July 17 surged sharply on Polymarket, with the YES contract price climbing 31.5 percentage points in the past 24 hours to 85.0%, up from 53.5% roughly a day earlier. This dramatic repricing reflects a swift shift in market sentiment around the event.
Whale activity aligned closely with the price move. Over the same period, 61 unique whale traders bought $9K worth of YES contracts and sold $4K, resulting in a net $5K inflow into YES positions. This volume of whale buying strongly supported the upward price momentum on a market that saw total 24-hour volume of $7K, indicating whales accounted for the majority of recent trading.
Since inception, the market has recorded $22K in lifetime volume with 270 unique traders participating, suggesting a moderate level of interest and liquidity.
