The probability that Iran will take military action against a Gulf State on July 15 surged 47.0 percentage points in the past 24 hours, climbing from 43.5% to 90.5% according to Polymarket Breaking data.
This rapid repricing was accompanied by whale activity that aligned with the price move. Over the same period, whales bought $6K worth of YES contracts and sold $2K, resulting in a net flow of $3K into YES positions. The market saw participation from 62 unique whales out of 172 total unique traders, indicating significant involvement from large accounts.
The total 24-hour trading volume in this market reached $6K, contributing to a lifetime volume of $14K on Polymarket. However, it is notable that the Polymarket Breaking YES price at 90.5% differs substantially from the Polydata on-chain mid-price, which stands at 24.5%, reflecting a divergence between off-chain and on-chain pricing data.
Overall, the combined surge in price and supportive whale buying signals a reassessment of the likelihood of Iran engaging in military action on the specified date, with large traders reinforcing the market’s bullish repricing over the past day.
