Iran's Blockade Will Likely End This Year — But Don't Call It a Victory Yet
At 76% and rising, the odds now favor a US announcement ending the Iranian blockade by December 31, 2026 — and the surrounding market evidence explains why.
Based on: The Hormuz Blockade Lifts Before Year-End — But the Strait Stays Dark for Months

The money now leans clearly toward one conclusion: the United States is likely to formally announce an end to the Iranian blockade before the year is out. At 76% — up more than six points in a single day — the December 31 deadline has become the dominant outcome in a market that spans multiple possible resolution dates. That is a strong signal, not a certain one, but it is strong enough to argue with conviction: barring a significant diplomatic or military rupture, the blockade ends on paper in 2026.
The broader picture reinforces this read without overselling it. The ceasefire contract — asking whether the US ceasefire against Iran continues through August 25 — sits at 100%, suggesting that the current pause in hostilities is, for practical purposes, locked in through the near term. A diplomatic meeting between Washington and Tehran by March 2027 is priced at 68%, pointing to a negotiating channel that remains open and active. Meanwhile, a US invasion of Iran before 2027 sits at just 16%, which means the shooting-war scenario that would scramble everything is firmly in the minority. Together, these numbers sketch a world in which both sides are managing toward an exit, not an escalation — which is exactly the environment in which a formal announcement becomes possible.
What would have to be true for this pricing to make sense? A negotiating process, however messy and indirect, would need to be producing real movement behind closed doors. The jump in near-term deadline contracts — October 31 surging as a contender, September 30 climbing to 41%, even September 14 crossing 24% — suggests that whoever is participating in this market with serious capital believes resolution could come faster than the calendar's end, not slower. The December 31 contract benefits from that compression: it is the broadest net, and as earlier deadlines gain credibility, the probability that at least one of them fires flows upward into the year-end number. People with informed views on the pace of US-Iran back-channel talks appear to be the ones pushing these numbers.
The honest caveat sits in the Strait itself. Even if the US announces an end to the blockade, the waterway is not snapping back to normal. Strait of Hormuz traffic returning to normal by December 31 is priced at only 40%, and by September 30 it sits at a mere 12%. A formal announcement and physical reality are two different things — and the gap between them is wide. The scenario that breaks the bullish case on the announcement itself is simpler: negotiations collapse, the ceasefire frays after August 25, or domestic politics in either capital make a formal declaration toxic. At 24% probability, that outcome is real, not theoretical.
This argument is the market's, decoded — not investment advice.
