The Strait of Hormuz is a critical route for energy shipments, but reports that oil is moving through it again do not establish that ordinary commercial traffic has resumed. The latest PortWatch observation cited in the available reporting recorded 1 vessel, against a stated pre-crisis baseline of 85 per day. That leaves a basic question unresolved: is vessel traffic recovering steadily, or are reports of individual shipments being mistaken for a broader return to normal?
Kalshi’s contract does not ask whether any oil or vessel passes through the strait. It asks whether the seven-day moving average of transit calls reported by IMF PortWatch rises above sixty before a specified deadline. Traders put that outcome at 14% as of 2:05 p.m. ET on Oct. 4. The market’s shorter time horizon is markedly less optimistic than its longer ones: the same threshold is priced at 44% before July 2026 and 71% before January 2026. Those are traders’ current beliefs, not forecasts, and the contracts are separate questions rather than a single partition of possible outcomes.
The evidence behind the uncertainty points in different directions. A brief published on October seven conditions relayed a report that oil was moving through the waterway again, but said it had not independently confirmed that report. It also relayed a report that Iraq was shipping oil through the strait and Iran’s stated position that the waterway would remain closed until the United States met seven conditions. Neither report, on its own, establishes a sustained return to routine transit. The PortWatch figure cited in that brief is dated late September, so it does not settle what traffic has done since.
Security reports make the distinction between isolated movement and normal passage consequential. An October brief cited Reuters reporting of three separate tanker strikes, with the attackers unidentified. The same brief cited reporting that crude exports had largely returned to pre-war levels while refined-product flows remained constrained. Export levels and transit calls are not the same measure: the former report does not show that the strait’s daily vessel traffic has returned to its stated baseline. Nor does the available reporting establish who was responsible for the attacks or what would produce a durable reopening.
For now, the market offers a clear contrast in traders’ expectations, but not confirmation of a recovery. The contract for a return above sixty calls before early November is priced at 3%, while the contract for before January 2026 is at 14%. Trading in the longer-dated contracts is much thinner: the farthest-out contract recorded 81 contracts traded over the last day, compared with 24,496 contracts traded over the last day for the nearer-term contract. That difference counsels against treating the longer horizon’s price as equally well-supported. The decisive evidence would be updated transit observations showing sustained activity, alongside independent confirmation of reported shipments; until then, the timing of normal traffic remains uncertain.
