The high-stakes prediction market on Polymarket, "US forces enter Iran by March 31?", has closed with an overwhelming consensus for a "No" resolution. With a substantial trading volume of over $70 million, the market's final prices reflected a 0.0005 probability for "Yes" and 0.9995 for "No," indicating a near-certain belief among traders that active US military personnel would not physically enter Iran's terrestrial territory by the specified deadline.

This market gained significant attention amidst the backdrop of the "2026 Iran war," which commenced on February 28, 2026, with joint US-Israeli strikes on Iran. The market's resolution criteria were precise: it would resolve to "Yes" only if active US military personnel, including special operation forces, physically entered Iran's terrestrial territory by March 31, 2026. Entry into maritime or aerial territory, or by military contractors, advisors, or diplomatic personnel, would not qualify.

Leading up to the March 31 deadline, the United States executed its largest military buildup in the Middle East since the 2003 invasion of Iraq, deploying extensive air, naval, and missile defense assets. By late March 2026, thousands of US Marines and sailors aboard the USS Tripoli, along with elements of the 82nd Airborne Division, had arrived or were en route to the region. These ground-capable forces were positioned for expeditionary operations, crisis response, and potential limited ground engagements.

Reports from late March indicated that the Pentagon was indeed preparing plans for potential weeks-long ground operations in Iran, which could involve raids by Special Operations Forces and conventional infantry, falling short of a full-scale invasion. Discussions also surfaced regarding the possibility of seizing strategic locations like Kharg Island, a crucial oil export terminal.

However, despite this significant military posturing and strategic planning, multiple credible sources explicitly stated that there had been no official announcement of US ground troops entering Iranian territory by March 31, 2026. US officials, including President Donald Trump and Defense Secretary Pete Hegseth, repeatedly denied that a decision had been made to introduce ground troops into Iran, often framing the deployments as a form of coercive diplomacy and leverage in ongoing settlement talks. President Trump also publicly stated in late March that he expected US operations in Iran to wrap up within weeks and that the US "can achieve all of our objectives without ground troops."

The Polymarket odds, reflecting the collective intelligence of thousands of traders, accurately anticipated this outcome. The near-zero probability for a "Yes" resolution underscored the lack of confirmed terrestrial incursions by the deadline. While the broader conflict and US military presence in the region continue to be a dynamic situation, the specific condition for this prediction market was not met by March 31, 2026, leading to a clear "No" resolution.
