The highly-watched Polymarket prediction market, querying whether active US military personnel would physically enter Iran's terrestrial territory by March 31, has officially resolved to "No." With the deadline now passed, the market's final prices, which saw the "Yes" outcome trading at an exceptionally low 0.0035, accurately foreshadowed the absence of such an event.

This market, which attracted a substantial trading volume of nearly $47 million, underscored profound global interest in the escalating tensions between the United States and Iran. A direct US ground intervention in Iran would represent a dramatic escalation of the conflict that commenced with US and Israeli airstrikes on February 28, 2026. Such an action carries immense geopolitical implications, including potential for regional destabilization, significant economic repercussions, and a humanitarian crisis.

Leading up to the March 31 deadline, the Middle East witnessed a substantial increase in US military presence. Reports indicated that over 50,000 American troops, including Marines and elements of the 82nd Airborne Division, had been deployed to the region. The Pentagon was actively preparing for potential "weeks of ground operations" and developing contingency plans for "limited ground raids" targeting strategic sites like Kharg Island, a crucial oil export terminal, or coastal positions near the Strait of Hormuz.

However, despite these preparations and the ongoing air and naval campaign against Iranian targets, multiple credible sources confirmed that no US ground forces had entered Iranian territory by the March 31 deadline. Military.com reported on March 30, 2026, that there had been "no official announcement that US ground troops have entered Iranian territory or that a full-scale ground invasion has been ordered." Similarly, Bitcoin.com News stated on the same date that "no credible reports confirm that any US military personnel have entered Iranian territory as of March 29, 2026."

The market's odds reflected this reality, with the probability of a "Yes" resolution remaining extremely low. On March 29, 2026, the odds for US forces entering Iran by March 31 were only 13%, even as predictions for entry by April 30 or year-end 2026 stood much higher at 71% and 78% respectively. This divergence highlighted the market's belief that while a ground entry was possible at a later date, it was highly improbable by the immediate deadline. Public sentiment in the United States also largely opposed ground troop deployment, with an Ipsos poll conducted March 27-29, 2026, revealing that 76% of Americans would oppose sending US troops into Iran.

President Donald Trump, while acknowledging the ongoing conflict and military options, had also expressed a desire to conclude US involvement within weeks. This sentiment, combined with the lack of confirmed terrestrial incursions, contributed to the market's eventual "No" resolution. The outcome underscores the high bar for direct ground engagement in a conflict of this magnitude, even amidst significant regional military buildup and sustained aerial operations.
