Prediction Markets: Less Than 50% Chance of Strait of Hormuz Reopening This Year
Claire Weston
Kalshi and Polymarket price the odds of the Strait of Hormuz returning to normal traffic by year-end at 38%–48%, as US-Iran talks stall over Tehran's expanded demands — leaving the outlook for the world's most critical oil chokepoint in limbo.
What are the prediction markets actually pricing?
Kalshi puts the probability of normal strait traffic resuming before January 1, 2027 at just 38%. Polymarket is slightly higher at 48%.
Kalshi defines "normal traffic" as a seven-day moving average above 60. This means → the bar is not "some ships get through" — it is traffic volume back to pre-blockade levels.
Both prices have been sliding lower in recent weeks. In plain terms = less money is betting on a deal this year, and more money is betting the standoff drags on.
Where did the talks break down?
The US, Iran, and mediators Qatar and Pakistan had expected to announce a deal last week. The core offer: give Iran partial control over strait transit.
Iran then raised the stakes. Security council chief Mohammad Bagher Zolghadr listed preconditions: the US must stop threats against Iran, permanently end wars against Iran and its allies, lift the naval blockade, withdraw troops from Iran's perimeter — plus war reparations, sanctions relief, and release of frozen assets.
This means → Iran turned a narrow "transit-for-oversight" deal into a sweeping geopolitical settlement demand. The negotiation's difficulty jumped by an order of magnitude.
What is driving the split inside Tehran?
US officials told Axios the expanded demands reflect an internal rift, not a unified position.
President Masoud Pezeshkian leans toward a deal — Iran's economy continues to deteriorate under sanctions, and he needs breathing room.
IRGC commander Ahmad Vahidi opposes concessions. In plain terms = the military does not want to trade the strait — a strategic card — for an economic agreement. Two policy lines are pulling in opposite directions at the top.
How does Trump's stance shift market pricing?
Trump said Sunday that with talks stalled, he is willing to let economic pressure do more of the work.
This means → Washington will not offer concessions to unlock a deal in the near term. The strategy is to wait — using the cost of sanctions and blockade to force Iran to move first.
That statement pushed short-term deal expectations lower. The Strait of Hormuz carries a critical share of global crude exports, and whether the uncertainty over its reopening can clear before year-end remains the market's central pricing variable.
