Which countries will send warships through the Strait of Hormuz by August 31?

Traders currently price "US" at 8% for "Which countries will send warships through the Strait of Hormuz by August 31?". Over the past 24 hours that probability moved down 1.5 points. Full distribution: US 8%, Netherlands 2%, Italy 2%, UK 2%. The market has traded $221K in total volume and resolves Aug 31, 2026. Escalating US-Iran naval posturing amid stalled reopening talks and sharply reduced shipping volumes through the Strait of Hormuz forms the core driver of trader sentiment for this market. With traffic at roughly 8-12 vessels daily versus the pre-crisis 130-140, Brent crude has incorporated a persistent geopolitical risk premium, while war-risk insurance rates and tanker charter costs remain elevated due to missile threats and the US blockade of Iranian ports. Recent statements from Tehran demanding sanctions relief and reparations before any normalization, contrasted with Washington’s assertions of control, have kept uncertainty high as the August 31 resolution nears. Diplomatic efforts with Oman and potential last-minute naval escort decisions by the US, India, or other powers represent key swing factors that could shift probabilities, though historical precedents show such transits often require clear de-escalation signals to materialize before deadlines.
