The probability that the US will reissue Iran oil sanction relief by July 31 dropped sharply by 39.5 percentage points over the past 24 hours, falling from 47.5% to 8.0% on Polymarket. This dramatic repricing signals a swift shift in market sentiment on the question.
Despite the plunge in the YES contract price, whale activity diverged from the price action. Large traders increased their net position in the YES outcome, indicating buying interest even as the market odds collapsed. This divergence between whale flow and price movement is notable, as it suggests differing interpretations of the underlying fundamentals or potential anticipation of a reversal.
The market recorded $14K in volume during the 24-hour window, reflecting moderate trading activity amid the volatility. The sharp decline in the YES price contrasts with the whale flow, which typically moves in alignment with price changes but here moved against the tape.
This combination of a steep drop in implied probability alongside whale buying points to a complex dynamic in how traders are processing information around the US reissuing sanction relief. The market is presently pricing a low chance of relief by the end of July, but whale activity indicates some participants see value or potential upside in the contrary view.
