The market for “US reissues Iran oil sanction relief by July 31?” saw its YES contract price collapse 38.5 percentage points in the past 24 hours, dropping from 57.5% to 19.0% on Polymarket as of July 13, 2026. This sharp repricing reflects a significant shift in trader sentiment regarding the likelihood of sanction relief being reissued by the specified date.
Despite the steep price decline, whale flow diverged from the tape, indicating that large traders have not aligned their positions with the falling odds. This divergence suggests that while retail or smaller traders pushed the price down aggressively, whales either maintained or increased exposure to the YES outcome, signaling skepticism about the downturn in probability.
The disconnect between whale flow and price movement highlights uncertainty and contested views about the US administration’s approach to Iran oil sanctions ahead of the July 31 deadline.
The combination of a dramatic price drop and whale divergence points to a contested market consensus, with large traders potentially betting on a last-minute policy shift despite broader market pessimism. This tension underscores the complexity and fluidity of geopolitical risk pricing in prediction markets.
