The highly-watched Polymarket prediction market, which posed the question "US x Iran ceasefire by March 31?", has officially resolved to "No." With the resolution date now passed and final prices showing a 'Yes' outcome at a mere 0.0005 and 'No' at 0.9995, the market accurately reflected the ongoing and intensifying conflict between the United States and Iran, rather than any de-escalation by the specified deadline.

This market, which saw a substantial trading volume of $44,247,674, defined an "official ceasefire agreement" as a publicly announced and mutually agreed halt in direct military engagement, requiring clear public confirmation from both governments or an overwhelming consensus of media reporting. The events leading up to March 31, 2026, painted a stark picture of escalating tensions, making a ceasefire highly improbable.

The "2026 Iran War" officially commenced on February 28, 2026, with joint US-Israeli airstrikes targeting various sites across Iran, including leadership compounds and military infrastructure. This marked a significant escalation following decades of unresolved disputes over Iran's nuclear program and regional influence.

Throughout March, rather than moving towards a ceasefire, the conflict intensified. The United States deployed thousands of ground-capable forces, including Marines and elements of the 82nd Airborne Division, to the Middle East, with the Pentagon reportedly preparing for potential ground operations in Iran. This military buildup, described by some lawmakers as the "biggest military engagement we've had since the war in Afghanistan," underscored a deepening involvement.

Diplomatic efforts to de-escalate the situation proved largely unsuccessful. Around March 25, 2026, Iran dismissed a US ceasefire proposal, issuing its own counter-proposal that included demands for reparations and Iranian control over the Strait of Hormuz, conditions likely unacceptable to the White House. Iranian Foreign Minister Abbas Araghchi explicitly stated on March 31, 2026, that Iran was not seeking a ceasefire but a "complete end to the war," emphasizing the need for guarantees against future attacks and compensation for damages. He clarified that contacts with the US were limited to message exchanges, not formal negotiations.

The market's overwhelming odds against a ceasefire, despite a brief surge in 'Yes' probabilities around March 21-24 that sparked discussions of potential insider trading on Polymarket, ultimately reflected the geopolitical reality. The consensus among traders, as evidenced by the final prices, correctly anticipated the lack of an official truce. The market's resolution highlights the continued state of military engagement and diplomatic stalemate between the United States and Iran, signaling ongoing instability in the Middle East beyond the March 31 deadline.
