US-Iran Ceasefire Reached by July 31, Earlier Than Expected
US x Iran Effective Ceasefire by...? (2 week pause)
Polymarket prices this August 31 at 95%.
A continuous 14-day period without qualifying U.S. military action against Iran was achieved by July 31, setting the effective ceasefire date earlier than many anticipated. This outcome came despite ongoing tensions and military actions reported by various outlets. The decisive moment appears to have been a period of de-escalation that allowed the two-week pause to be completed before the end of August. While the market had favored an August 31 ceasefire with 95% probability, the actual events unfolded more rapidly, indicating a swifter, albeit fragile, halt to direct military engagements.
Background
The path to this ceasefire was marked by significant volatility, with market odds for a ceasefire date swinging back and forth. Reports indicated continued military activity, including a U.S. military strike on Iran and Iran's declaration of the Strait of Hormuz closure after an 'unauthorised' vessel was hit. Even as the ceasefire was declared, some analysts cautioned that physical oil markets would remain stressed, suggesting that underlying geopolitical tensions persisted despite the pause in direct military action.

Analysts will be watching for any further military actions or diplomatic overtures that could either solidify or shatter this fragile de-escalation.
