The implied probability of Iranian military action against a Gulf State on July 13 plummeted 43.0 percentage points over 24 hours on Polymarket, falling from 77.5% to 34.5%. This sharp repricing signals a major shift in market sentiment on the event’s likelihood.
Despite the sizable drop in the YES price, whale flow diverged from this move, showing no significant net investment into YES positions. This divergence between price and large trader activity suggests that while the broader market is rapidly discounting the chance of Iranian military action, whales are not reinforcing the selloff with matching bets.
Trading volume over the same period reached $44K, indicating active participation amid the volatility.
This price and flow dynamic highlights a market in flux, where retail-driven repricing is not fully supported by the largest bets. It suggests that the consensus on Iran’s military prospects is unsettled, with significant skepticism emerging despite the absence of confirming whale pressure.
