Will there be a major military escalation at the Strait of Hormuz this quarter (a state-level strike, seizure campaign, or attempted closure), rather than continued brinkmanship?
Horizon — by end Q4 2026
Scored to 2026-10-15: the criterion says “within 90 days”, 77 days before the horizon above. The criterion is what the read is settled against.
Resolves 'occurred' if, within 90 days, there is a state-attributed military action that materially disrupts Hormuz transit (a naval engagement, a sustained seizure campaign, mining, or a declared…

- 01ActorThe decider — weighs a coercive escalation against the cost of acting. The ex-ante incentives are genuinely balanced, which is why open-source analysis sits at a coin toss.
- 02ActorCounterparties — would respond to a closure, raising the decider's cost. That cost is visible to everyone and is already priced; it does not break the tie.
- 03Tripwirethe decider's resolve and intent, read through primary sources rather than the public record.
- 04ReasoningA major escalation is a single decision-maker's call, and the public record genuinely supports either path: the cost of acting is visible and already priced, while the resolve behind the threat is not. We hold both paths at their true weights rather than forcing a lean, and a primary-source read on the decider's resolve is what moves the distribution decisively.

argues against carrying a directional chokepoint position on the public picture alone. Size only once a network read or a hard tripwire resolves the decider's intent.
Resolves 'occurred' if, within 90 days, there is a state-attributed military action that materially disrupts Hormuz transit (a naval engagement, a sustained seizure campaign, mining, or a declared closure) confirmed by two of: IMF PortWatch transit data, JMIC/UKMTO advisories, or major-wire reporting. Resolves 'did_not_occur' if brinkmanship continues without a material transit disruption.
