It turns chiefly on whether a near-term ceasefire or negotiation gives Trump reason to declare a visible de-escalation.
- The White House or an authorized defense official must make an unambiguous public statement by October 15, leaving only 12 days.
- Blockades imposed during acute confrontations rarely end within three months absent a ceasefire, capitulation, or major diplomatic deal.
- A verified Iran-US ceasefire or reopened shipping agreement before October 15 would sharply raise the odds.

A blockade announced only ~3 months ago rarely ends that fast without a major diplomatic breakthrough, and none is visible.
- Naval blockades historically persist for years (e.g., Cuba 1962 lasted decades in modified form); a 3-month window is extremely short for a policy reversal of this…
- Trump would need a concrete concession from Iran (nuclear deal, regional de-escalation) to justify lifting it, and no credible negotiation track has been reported as of…
- The only scenario that moves this above 20% is a sudden Iran-US backchannel deal or a military incident forcing de-escalation, neither of which has surfaced.

A 12-day window after a July 13 Trump-ordered blockade needs an already-ripe Iran deal Trump can claim as a win.
- Trump or an authorized Pentagon/State official must publicly declare the blockade ended or suspended by 23:59 ET 15 Oct.
- US naval interdictions and Iran sanctions historically last years, not 90 days, absent a signed nuclear or hostage bargain.
- Only an imminent, publicly telegraphed Tehran concession would flip this; none is visible in the remaining fortnight.

Short 12-day window with no diplomatic breakthrough signal; blockades of this type rarely end abruptly.
- Only 12 days remain and no public negotiation track is reported as near resolution.
- Trump administration has framed the blockade as a pressure tool, making early reversal politically costly absent a deal.
- A sudden Iran nuclear/sanctions deal or major escalation de-escalation announcement would be the main thing to flip this.

With only twelve days left, the US administration lacks both diplomatic momentum and political motivation to dismantle the blockade.
- Lifting a major maritime blockade requires extensive bilateral concessions or de-escalation treaties that are nowhere in sight.
- The 12-day timeline before October 15 leaves virtually zero operational runway for an unexpected total reversal in policy.
- A formal suspension would only trigger if an emergency interim maritime deal is abruptly brokered by regional intermediaries.

Only a sudden US-Iran de-escalation deal in the next 12 days would end the blockade.
- Trump reinstated the blockade July 13, 2026, and no negotiations or sanctions relief are publicly scheduled before October 15.
- Terminating it requires a presidential order or CENTCOM directive; Congress has moved to tighten, not loosen, Iran policy.
- Base rate for reversing a US naval blockade within 90 days is near zero; the 2019 tanker-escort standoffs lasted months without formal lifting.

Resolution criteria
On July 13, 2026, Trump announced the United States would reinstate its naval blockade of Iran, targeting Iranian ships and customers. This market will resolve to “Yes” if the United States government, or an authorized representative of the United States government, publicly and officially announces the end, termination, lifting, or suspension of the United States’ naval blockade on Iranian ships and ships of Iranian customers, between market creation and the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”. An announcement qualifies if it communicates that the United States will generally cease blocking vessel traffic for Iranian ships and customers, including an announcement that the blockade will not take effect at all, even if some restrictions remain (for example, an imposition of fees). An announcement does not qualify if it reflects only a limited or partial change that stops short of a general end or suspension of the blockade, for example, an exemption for a specific vessel, cargo, or port. A qualifying announcement must be a declarative statement of the United States government’s present termination or suspension of the blockade, previously-unan
