Prediction Markets: Less Than 50% Chance of Normal Strait of Hormuz Transit Resuming This Year
Claire Weston
Kalshi traders now put the odds of normal shipping through the Strait of Hormuz by year-end at just 44%, after Trump declared the Iran ceasefire 'over' and struck Iranian targets — a sharp reversal from days earlier.
How low are the odds, exactly?
Kalshi traders price the probability of normal transit resuming by December 1 at 44%. The earliest date with better-than-even odds is now January 1, 2027 (53%).
This means → the market's base case is that shipping through the strait stays disrupted for the rest of 2025, with the recovery window stretching past a year.
Rival platform Polymarket is slightly more optimistic, pricing a return to normal by December 31 at 59%. Both platforms use IMF PortWatch data and define "normal" as a 7-day moving average above 60 transits.
What flipped the outlook so fast?
As recently as July 4, Kalshi traders still gave better-than-even odds of normalization by October 1.
The trigger: Trump declared the Iran ceasefire agreement "over" and ordered strikes on Iranian targets after a commercial vessel was attacked.
In plain terms = the market had been pricing in a second-half recovery — one military escalation wiped that out in days.
What are analysts saying about supply?
Piper Sandler analyst Jan Stuart wrote Wednesday that strait traffic has "suddenly moved far from normal levels."
He added that "global oil supply is once again severely short" and that any hope of insurers lowering war-risk ratings within months has been dashed.
This means → the war-risk premium on tankers is unlikely to ease soon — and that premium is the key variable driving tanker operating costs and the routing of Middle Eastern crude flows.
What should investors watch?
Elevated war-risk premiums directly raise tanker operating costs, which in turn affect crude shipping prices and Middle Eastern oil trade routes.
In plain terms = oil can't move cheaply, insurance won't come down — so the risk premium baked into crude prices and shipping stocks stays stretched.
The indicator to track: whether the IMF PortWatch 7-day moving average of transits climbs back above 60 — the shared "normal" threshold used by both prediction platforms.
