US announces end of Iranian blockade by...?
I see only a small chance, around 6%, that the U.S. makes a clear official announcement ending the blockade before July 24. The more likely outcome is continued enforcement amid talks and strikes rather than a clean suspension.
Analysis
As of July 15, 2026, the U.S. position is still one of active enforcement, not de-escalation. AP reported that the U.S. military reimposed the blockade on Iranian ports early Wednesday after renewed attacks on shipping, while CENTCOM’s recent official releases describe vessels being redirected or disabled and refer to the blockade as ongoing. That makes the baseline expectation that the policy stays in place through July 24 unless there is a very explicit reversal.
The only realistic path to a Yes is a fast diplomatic turnaround, but the latest reporting does not point that way yet. AP reported on July 10 that the U.S. wanted Iran to publicly confirm the Strait of Hormuz is open and stop attacks, Reuters reporting said mediators were still trying to revive talks, and Trump said talks could continue even while he declared the ceasefire over. Those are all signs that negotiation channels still exist, but they are not the same as an official U.S. announcement that the blockade has been terminated or suspended.
The market is pricing some chance of a sudden U-turn, and that is not irrational because the administration has already reversed itself once this summer, including the June agreement that reopened the Strait and lifted the earlier blockade. Even so, the present mix of renewed strikes, sharper rhetoric, and continuing maritime enforcement makes a fresh public termination by July 24 look like a low-probability event rather than a close call. My assessment is therefore below the 8.5% market price and centered on the idea that the U.S. will keep pressure on Iran unless a new deal is reached almost immediately.
Arguments
For
- Arguments for Yes: Trump has already reversed blockade policy once this summer, so another abrupt change is procedurally possible if a new deal is struck.
- Arguments for Yes: Backchannel diplomacy is still active, and Reuters reporting suggests negotiators and mediators remain engaged even after the ceasefire unraveled.
- Arguments for Yes: A formal announcement could come quickly if Iran makes a credible public commitment to keep the strait open and stop attacking shipping.
Against
- Arguments against Yes: The blockade was just reinstated on July 13, and the latest official and media reporting describes it as actively being enforced.
- Arguments against Yes: CENTCOM’s recent releases describe disabling or redirecting vessels, which is the opposite of a public suspension or termination.
- Arguments against Yes: The diplomatic environment is still deteriorating, with more strikes threatened and no firm public date for a breakthrough.
Key drivers
- A sudden diplomatic breakthrough would be the main trigger for a qualifying end-of-blockade announcement.
- The administration’s willingness to reverse course quickly is real, but it depends on Iran making enough concessions to justify a public reset.
- Continued attacks on ships or U.S. assets would push the White House toward keeping the blockade in place.
- The market’s 8.5% Yes price implies some belief in a near-term policy swing, but the current news flow does not strongly support it.
Risk factors
- A new Iranian strike on commercial shipping could harden U.S. rhetoric and make an end announcement even less likely.
- If the White House keeps signaling that talks are conditional and unresolved, the blockade may continue without any formal suspension language.
- Even if enforcement is loosened in practice, the market requires a clear official announcement, so ambiguous partial easing would not resolve this Yes.
- The short time window leaves little room for a complex diplomatic process to produce a clean, public policy reversal.
Scenarios
Best case
A rapid backchannel agreement produces a White House or CENTCOM statement before July 24 that explicitly suspends or ends the blockade in exchange for Iranian commitments on maritime safety and Hormuz access.
Most likely
The blockade remains in effect through July 24 while U.S.-Iran contacts continue in the background, but there is no unambiguous official announcement ending it.
Worst case
Retaliatory attacks continue, the U.S. escalates strikes and maritime enforcement, and no official statement ever clearly ends or suspends the blockade before the deadline.

2026: Trump's dream year?
AI72%MKT6%Edge+66Hidden GemGiven that the three policy pillars of the bull case (tax cuts/deregulation, likely Fed rate cuts, and a weakening of regulatory restraints via the Supreme Court) are already in place, the outcome now primarily hinges on the 2026 midterms and a small residual macro/geo risk; I assess a substantially higher chance of the bull case occurring than the market does.

Next Claude Opus released by...?
AI41%MKT97%Edge-56HypedThe market is pricing in a near-certain August Opus launch, but Anthropic's public materials still show Opus 4.8 as the current Opus model and there has been no official new Opus announcement in the past week. I think the true probability is much lower than the market's 97.55% implied price.
