US clears Iranian mines in Strait of Hormuz amid stalled talks

U.S. destroyers have cleared Iranian mines from the Strait of Hormuz, reopening shipping lanes as negotiations between the U.S. and Iran remain stalled in Islamabad. The Polymarket contract on a U.S.-Iran ceasefire by April 15 sits at 100% YES, pricing it as a certainty even as military activity escalates.

## Market reaction

The clearing operation could affect the likelihood of the UK sending warships through the Strait by April 30, though current odds for that contract are not specified. The stalled Islamabad talks, combined with Iran’s mine-laying, create a volatile backdrop for the US-Iran ceasefire market, still locked at 100% YES.

## Why it matters

The market for military action against Iran ending before April 2026 faces pressure from the mine-clearing operation and stalled negotiations, which point to continued military tensions rather than a quick resolution.

The source carries a tier-3 classification. The U.S. mine-clearing operation reads as both deterrent and provocation, pulling ceasefire and military action markets in opposite directions. At 100% YES, the ceasefire-by-April-15 contract is priced as done, but the underlying situation is unstable.

## What to watch

Traders should monitor any UK Ministry of Defence announcements on warship deployments. Updates from CENTCOM or shifts in diplomatic language from Trump or Macron could move market odds quickly.
