Iran has solidified its control over the strategically vital Strait of Hormuz, leading to a significant shift in market expectations regarding a US-Iran ceasefire. Prediction markets now show a 99.6% probability of a ceasefire by April 15, a dramatic increase from just 14% 24 hours prior. This consolidation and the subsequent easing of sanctions appear to have bolstered the Iranian regime's position, with odds for its collapse by June 30 falling to 8.5%.

The market reaction has been swift, with the April 15 ceasefire market spiking 24 points in minutes. The liquidity in these markets, with daily face value at $13.7 million, signals strong conviction among traders reacting to geopolitical developments.

Iran's enhanced leverage over the Strait and the lifting of sanctions provide a stronger negotiating stance, potentially reducing immediate pressure for a ceasefire. Traders are now assessing Iran's long-term strategic objectives against current market pricing.

Key factors to monitor include responses from President Trump, statements from US officials, and any diplomatic efforts from intermediaries like Oman or Qatar.
