As of March 29, 2026, the U.S. Department of Defense has positioned more than 50,000 troops across the Middle East and is drafting contingency plans for limited ground raids inside Iran, but no American forces have entered Iranian territory. The conflict entered its fifth week after American and Israeli airstrikes struck Iran on February 28. Recent deployments include thousands of Marines, Army infantry, and units from the 82nd Airborne Division. Major outlets such as The New York Times, The Washington Post, and Reuters have confirmed the troop buildup but report no boots on Iranian ground.
Ground Raid Plans Remain Contingent
The Washington Post reported on March 28 that Pentagon planners are preparing for weeks of limited ground operations — special forces and infantry raids targeting Iran's Kharg Island (handling about 90% of oil exports) and coastal positions near the Strait of Hormuz. However, these plans remain unapproved by President Trump. Reuters disclosed on March 24 that thousands more soldiers are expected, while Axios detailed on March 27 that the White House and Pentagon are weighing at least 10,000 additional combat troops. The Wall Street Journal and Iran International noted the total deployed force could exceed 17,000 ground troops once approved. CNN reported that over 1,000 soldiers from the 82nd Airborne were preparing to deploy as of March 24, and Fox News confirmed on March 29 that 3,500 Marines aboard the USS Tripoli had arrived in the region.
Iran Warns of Market Manipulation
Iran's parliament speaker, Mohammad Bagher Ghalibaf, took to X this week to warn that pre-market war headlines are often engineered rather than organic. He described the initial price reaction as a reverse indicator: if positive headlines spike prices, short; if negative headlines dump prices, go long. This echoes Tehran's broader accusation that U.S.-linked war announcements have repeatedly triggered artificial swings in oil and equity markets, giving certain players an advantage — a claim Washington denies.
Prediction Markets Price High Probability of Entry
Polymarket, the leading prediction market by volume, shows a 71% probability that U.S. forces will enter Iran by April 30 and a 78% probability by December 31, 2026, based on $49.6 million in total trading volume for the “US forces enter Iran by?” contract. The March 31 contract alone generated $34.5 million in volume, indicating heavy short-term speculation. Comments on the platform reveal traders watching for special operations activity, though sharp price moves have also been attributed to large single trades. Iran-related prediction markets have faced scrutiny over possible insider trading tied to earlier airstrikes, but no formal findings have been published.
Economist Steve Hanke Warns U.S. Is Losing
Johns Hopkins economist Steve Hanke has said the United States is losing the Iran war and is functionally insolvent. The conflict's fifth week sees airpower doing the bulk of the work, mirroring early stages of past U.S. campaigns. Whether ground operations materialize depends on diplomatic negotiations. Any confirmed entry of U.S. forces into Iran would mark a major escalation. As of March 29, that has not occurred.
