A $12 million question on Hormuz shipping is about to resolve and nobody's arguing anymore
Fifteen hours from close, Polymarket's market on whether Strait of Hormuz shipping traffic returns to normal by September 30 sits at 0%. Not close. Not contested. Zero. And yet $570K changed hands in the last day on a $12M lifetime market that's already decided.
That's what a locked-in verdict looks like. The crowd isn't debating the outcome; it's collecting on it. One of the most-watched world questions of 2026, a market that ran all summer on tanker headlines and Iran diplomacy, is quietly settling NO while the news cycle has moved on to a proposed 7-day plan to end the war.
The resolution criterion is specific: a 7-day moving average of at least 60 daily transit calls, per IMF Portwatch. It never got there. Tanker flows through the world's most important oil chokepoint stayed below the pre-crisis baseline for the entire window. That's the story the market is telling and mainstream coverage isn't: the disruption didn't end, it just stopped being news.
IMF Portwatch's next publication is what matters now. Watch whether October's 7-day average starts climbing off the floor or settles in as the new normal.
Analysis of the Day
Will the highest temperature in Chicago be between 74-75°F on October 1? Resolves tomorrow · $1K lifetime volume | NO 26% |
The October 1 forecast high is 71°F with an ensemble median of 68.8°F and a p90 of only 73.0°F, the 74-75°F target sits above the 90th percentile of the 31-member ensemble, meaning fewer than 10% of model runs reach that range. The ensemble spread is 7.5°F (p10-p90), so while there is meaningful uncertainty, the bulk of probability mass clusters well below 74°F. Hitting exactly 74-75°F requires an outcome in the far right tail of the forecast distribution.
