The Strait of Hormuz is still running far below the traffic threshold this market uses for “normal.” Traders put Before July 1, 2027 at 52% and Before April 1, 2027 at 47% — nearly even on whether the IMF PortWatch seven-day average of transit calls clears 60 by mid-2027.

How this market pays

You’re betting on when the IMF PortWatch seven-day moving average of transit calls through the Strait of Hormuz first rises above 60. Each date in the table is its own Yes/No bet — “did the average clear 60 before this date?” — not a single race where only one winner gets paid. So if the average first clears 60 on November 15, 2026, Before Dec 1, 2026, Before Jan 1, 2027, Before Apr 1, 2027, and Before Jul 1, 2027 can all pay Yes on that same crossing.

Other bets on the same average — including Before Aug 15, 2026 near 1% — sit outside the table. Earlier calendar lines that already expired without a clear of 60 are finished.

Kalshi confirms the figure from the IMF PortWatch seven-day moving average of transit calls through the Strait of Hormuz.

How to look at each side

The case for Before Jul 1, 2027. Why that line sits at 52%: MacroMicro, which republishes the IMF PortWatch series, put the seven-day average at 4.43 on August 9, 2026 — still far below the market’s 60 threshold. Straits.live counted one commercial vessel through the strait on August 9 against a peacetime pace near 73 a day, and put the disruption near 165 days; it also notes PortWatch can lag same-day counts. Clearing 60 before July 1, 2027 is the ask traders treat as roughly even money: the calendar runs almost a year from that August 9 print, without requiring the average to be fixed by fall 2026. Peacetime traffic near 73 a day means “normal” here is recovery past 60 on PortWatch’s average, not whether another tracker’s daily count looks busy today.

The case for Before Apr 1, 2027. Why Before April 1, 2027 still sits at 47%: the April line is only three months tighter than July, and the ladder prices that gap at about five percentage points. Getting the PortWatch average above 60 by spring 2027 still needs a large climb from about 4.4. MarineTraffic, a separate vessel-tracking service, counted 84 confirmed crossings from August 3–9 in its August 10 monitor — a different methodology from PortWatch transit calls, and not the series Kalshi uses to settle. The April case at 47% is that the PortWatch average clears 60 by spring 2027 rather than needing the full run into midsummer, while still treating that average — not a one-day ship count — as the number that has to clear 60.

What the odds are saying

Traders put a 52% chance on the PortWatch seven-day average clearing 60 before July 1, 2027 — and about a 48% chance it has not done so by then. Before April 1, 2027 sits close behind at 47%.

Earlier dates fall off steeply: Before Jan 1, 2027 is 37%; Before Dec 1, 2026 is 27%; Before Nov 1 and Oct 1, 2026 are 18% and 13%; Before Sep 1, 2026 is 3%. Before July and Before April sit only five percentage points apart. The steep disagreement is whether the average clears by late 2026 — not whether it is already near 60 today.

2 reasons Before Jul 1, 2027’s 52% chance can still move:

1. PortWatch can stay low while other trackers show more ships. MarineTraffic’s confirmed-crossing count and Straits.live’s commercial tally are useful context, but settlement is the IMF PortWatch seven-day average of transit calls. A rebound that shows up first on private ship-trackers can leave this ladder unchanged until PortWatch’s average clears 60.
2. The climb from about 4.4 to above 60 is still huge. Peacetime commercial traffic near 73 vessels a day shows how far below normal the PortWatch average sits. A rebound that only lifts the average into the teens or twenties still leaves the July line unpaid — so stretches where PortWatch stays near the August 9 print of 4.43 can move that 52% chance.

What to watch

IMF PortWatch’s seven-day moving average of Hormuz transit calls — the settlement series — plus same-week reads from Straits.live and MarineTraffic risk monitors that show whether commercial traffic is rebuilding even when PortWatch lags.
