Donald Trump has issued a 48-hour ultimatum to Iran: open the Strait of Hormuz fully or face US airstrikes on Iranian power plants. "The United States of America will hit and obliterate their various POWER PLANTS, STARTING WITH THE BIGGEST ONE FIRST," Trump wrote on Truth Social late Friday. The deadline expires Sunday evening GMT.

Prediction markets are pricing conflict, not compromise. The probability of a US-Iran ceasefire by March 31 sits at just 7.5% on Polymarket, with $1.44 million in 24-hour volume behind the bet. Meanwhile, traders put the chance of US forces entering Iran by month's end at 20.5%, a figure that implies significant military action short of full invasion. Regime change remains a fringe scenario at 1.8%. The broader Middle East picture compounds the risk: Israel launching a major ground offensive in Lebanon by March 31 trades at 98.3%, meaning markets see a region already at war. Taken together, traders believe Trump follows through on airstrikes but Iran does not capitulate, producing a prolonged standoff rather than a resolution.

The Strait of Hormuz carries roughly 20% of global seaborne oil. A sustained disruption, reprices energy markets worldwide. With ceasefire odds in single digits and multi-front conflict ongoing, professional investors should treat the next 48 hours as a live trigger for energy volatility.
