Will __ ships transit the Strait of Hormuz on any day by May 31?

There are six calendar days remaining in the market window (May 26–31, inclusive), which provides multiple independent opportunities for a daily transit count to reach 20; with daily publication by IMF Portwatch, any single high-count day will resolve the market to Yes. The market currently trades at 50/50, reflecting uncertainty or lack of recent public signals, but that price understates the combinatorial effect of multiple remaining observation days (multiple days raise the cumulative chance of at least one exceedance unless traffic is persistently suppressed).

Operationally, the Strait of Hormuz is a high-utility route for oil tankers, bulk carriers, and container ships, so absent sustained geopolitical escalation or economic collapse there is regular baseline traffic that produces occasional daily spikes; historically, on many recent occasions similar thresholds have been met on at least some days when the region is stable. No fetched news was available for this summary, so I assume no sudden, widely reported naval blockade, major military confrontation, or comprehensive port closures have occurred that would materially depress traffic across all remaining days.

Important structural factors: the data source (IMF Portwatch) publishes daily counts and allows in-window revisions, so a late revised upward count could qualify the market as Yes even if an initial publication missed it; conversely, any systematic undercounting or reporting lag in the Portwatch feed could reduce the practical chance of observing a qualifying day. Lastly, traffic dynamics are correlated across days — a single disruptive incident could suppress multiple days and sharply lower the probability, while normal commercial patterns or short-term demand spikes (e.g., cargo bunching, scheduled convoys, or weather-driven re-routing) could produce a single qualifying day quickly.

Balancing these factors, with multiple independent opportunities left, normal incentives for ships to transit the shortest route, and no confirmed large-scale disruption reported to date, I place the probability materially above 50% but not near certainty because regional volatility and reporting uncertainties remain relevant.
