Strait of Hormuz Contract Slides to 58.5% Yes on $4.60M Volume After 27-Point Reset

Polymarket’s “Strait of Hormuz traffic returns to normal by December 31?” contract implies Yes at 58.5% versus No at 41.5%, with $4,601,660 in matched volume. The move represents a sharp reset from the prior 85.5% price level, signaling a weaker consensus around normalization by the 2026-12-31 resolution date.
