# Strait of Hormuz traffic returns to normal by December 31?

DataSnack's model puts this at 6% seven days from now (10 Nov 2026); the market's number (Polymarket) is 9%. It has no graded forecasts yet; the first is graded on 12 Nov 2026.

## DataSnack's read

**Hormuz reopens on a US-Iran political bargain, and the calendar works against it**

A reopening would signal a US-Iran settlement and relief for oil and shipping costs. The model's case rests on time decay with 51 days left and no deal, plus small tilts from pump gasoline and WTI crude, at 7%.

## The numbers

- The market's number (Polymarket) now: 9% ([the market](https://polymarket.com/event/strait-of-hormuz-traffic-returns-to-normal-by-december-31))
- DataSnack's model, seven days from now: 6%
- The market closes: 1 Jan 2027
- How it resolves: This market will resolve to “Yes” if IMF Portwatch publishes a 7-day moving average of transit calls (“Arrivals of Ships”) for the Strait of Hormuz equal to or above 60 for any date between market creation and December 31, 2026. Otherwise, this market will resolve to “No”. Daily transit calls include container, dry bulk, roll-on/roll-off, general cargo, and tanker ships. Ships not reported by IMF Portwatch will not be considered. This market will resolve as soon as IMF Portwatch publishes a 7-day moving average of transit calls equal to or above the specified level, or once data has been pub…

## How the model works

Time decay: with 51 days left and no deal, the chance of a by-date event slips as the window shrinks. Pump gasoline and WTI crude, both ranked by the scan, add a tilt beyond that decay.

- With no breakthrough this week, the chance shrinks as the window shrinks, at about 2 of the pace of a constant hazard. DataSnack's author expected 1; the data say 2. Fits past data roughly.
- Each $1/gal rise in pump gasoline over two weeks moves the odds by about 0.0921 in log-odds, as the market reads pump prices as a sign of Hormuz stress or relief. DataSnack's estimate, not yet tested on data.
- Each $1/bbl rise in WTI crude over two weeks moves the odds by about 0.008 in log-odds, as crude carries the market's read of Hormuz supply stress. DataSnack's author expected 0.008 in log-odds; the data say 0.008 in log-odds ± 0.0066. A rough rule.
