The probability of Iran taking military action against a Gulf State on July 12 surged dramatically by 67.5 percentage points within 24 hours, rising from 14.5% to 82.0% according to Polymarket’s latest data.
This sharp move was accompanied by whale activity that aligned with the price increase, confirming the market’s reassessment rather than contradicting it. The combined on-chain flow and price action suggest a significant shift in sentiment among large traders about the likelihood of this event.
Trading volume over the last 24 hours reached $13K, reflecting active participation but not unusually high turnover for a breaking news-driven market.
The convergence of strong price momentum and whale buying indicates traders are increasingly pricing in a high chance of Iranian military action on the specified date. This consensus between price signals and large-scale flow underscores the market’s rapid adaptation to new information or developments related to geopolitical risks in the Gulf region.
