$100 Into $250 If Hormuz Stays Broken -- the US Just Bombed Iran and Polymarket Is Still Pricing a Recovery

The Strait of Hormuz carries about a quarter of all the oil that moves by sea. It has been running below normal since late February. The US just bombed Iran's Revolutionary Guard. And Polymarket is still paying roughly 2.5x on the bet that the waterway stays broken into the new year. Read that again, then look at the board.

Here's the part that's not in the headlines yet: the market that tracks whether Hormuz "returns to normal" already crashed this month -- and the crowd is quietly betting that crash was wrong.

Polymarket's contract resolves on hard shipping data. If IMF PortWatch's 7-day moving average of transit calls reaches just 60 at any point before December 31, the "Yes" side pays $1. Seeking Alpha reported those odds plunged to 51% after the US launched airstrikes targeting Iran's Islamic Revolutionary Guard Corps -- the lowest level since the contract opened, and down from a 91% high a month earlier.

As of this writing, Yes sits back at roughly 60%. That bounce is the setup.

The International Energy Agency is not as hopeful as the ticker. The IEA called the Strait "still unstable," said shipments only partially resumed in June, and warned that renewed US-Iran fighting is adding fresh uncertainty to crude -- which ended the week higher on the clashes. The crisis itself is five months old and counting. The 2026 Strait of Hormuz crisis began February 28, and IMF PortWatch has flagged reduced traffic through it ever since.

The trade is the No side. As of this run, Yes is bid 59c, ask 60c -- which puts No at roughly 40c. At 40c, $100 buys about 250 shares. If Hormuz traffic does not hit the 60-transit threshold by December 31, those shares settle at $250. That's a $150 profit on one position. If traffic recovers, the stake goes to zero. That's the deal, and the risk is real: 60 transits is a low bar, and one solid de-escalation clears it.

Here's the part that should make you feel early. The same question is priced 19 points apart on Kalshi. Kalshi traders put the odds of traffic returning to normal before January 1 at just 41% -- a 59% chance it stays broken, even with a month of extra runway. Polymarket is pricing "stays broken" at 40%. Two liquid markets, same underlying data, 19 points apart. One of them is wrong, and the one that's wrong has been wrong in the same direction for five months.

Over 30,000 vessels normally move through Hormuz every year per the shipping data. That flow is the world's energy jugular, and right now it's running below the threshold the market itself calls normal. Every airstrike, every Iranian response, every week of stalemate eats another week out of the recovery window. The crowd keeps pricing a return to normal that the data keeps postponing.

Five months. One airstrike. Two markets 19 points apart. The crowd has been waiting for this waterway to come back since February -- and it's still paying you to bet it won't. That trade doesn't show up twice.

Summary

The Strait of Hormuz traffic market ("Strait of Hormuz traffic returns to normal by December 31?") pays ~2.5x on No at roughly 40c after US airstrikes on Iran's IRGC pushed recovery odds from 91% down to ~51-60%. $100 on No returns $250 if IMF PortWatch transit calls stay below 60 through year-end. Kalshi prices the same question 19 points more bearish.
