The Pentagon has moved tens of thousands of troops into the Middle East and drawn up contingency plans for limited ground raids inside Iran, but no U.S. forces have entered Iranian territory as of March 29, 2026, at 5 p.m. Eastern time. The conflict, now in its fifth week after U.S. and Israeli airstrikes hit Iran on Feb. 28, has seen more than 50,000 American troops positioned across the region — up roughly 10,000 in recent days — including Marines, Army infantry, and 82nd Airborne Division units.
Troop Buildup and Ground Operation Plans
Multiple outlets including the New York Times, Washington Post, and Reuters have confirmed the deployments. The Washington Post reported on March 28 that Pentagon planners are preparing for weeks of limited ground operations inside Iran — raids by Special Operations forces and infantry targeting sites near Kharg Island (handling roughly 90% of Iran's oil exports) and coastal positions near the Strait of Hormuz. These remain contingency plans; no order has been issued and no approval granted. Reuters disclosed on March 24 that the U.S. was expected to send thousands more soldiers. CNN reported that over 1,000 soldiers from the 82nd Airborne were preparing to deploy as of March 24. Fox News reported on March 29 that 3,500 Marines aboard the USS Tripoli had arrived in the region for possible ground operations. President Trump has not ruled out a ground component but has not ordered one. Iran's parliament speaker issued a public warning that Iranian forces were “waiting for the arrival of American troops on the ground to set them on fire.” Diplomatic back-channel talks are ongoing through Pakistan as a third-party intermediary.
Prediction Markets Price 78% Chance of Entry by Year End
Prediction markets are pricing in a high probability that U.S. forces will eventually enter Iran, though not yet. On Polymarket, the largest prediction market by volume, the “US forces enter Iran by?” contract has drawn $49.6 million in total trading volume. The market gives a 13% probability of entry by March 31, 71% by April 30, and 78% by Dec. 31, 2026. The March 31 contract has generated $34.5 million of that volume alone, suggesting heavy short-term speculation. Comments on the platform show traders watching for Special Operations activity, though sharp price movements have also been attributed to large single trades from individual accounts. Iran-related prediction markets have drawn scrutiny over possible insider activity tied to the timing of earlier airstrikes, though no formal findings have been published.
Iran's Parliament Speaker Warns of Market Manipulation
Iran's parliament speaker Mohammad Bagher Ghalibaf extended warnings beyond the battlefield, telling X followers that headline-driven market moves around the conflict are frequently engineered rather than organic. He described pre-market “news” as deliberate setups designed to let certain players take profit before a reversal, calling the initial price reaction a reverse indicator — if positive headlines spike prices, short it; if negative headlines dump prices, go long. “See something tomorrow? You know the drill,” he wrote, urging traders to position against the early move. The remarks reflect Iran's broader accusation that U.S.-linked announcements around the war have repeatedly triggered artificial or insider-based swings in oil and equity markets, a pattern Tehran has raised before and Washington has denied.
Market and Geopolitical Risk Outlook
The pattern—air and naval strikes first, ground options held in reserve—mirrors early stages of previous U.S. military campaigns in the region. Whether it ends there depends on how the next phase of negotiations develops and whether either side is willing to accept the terms on the table. Any confirmed entry of U.S. forces into Iranian territory would constitute a major escalation and would generate immediate global reporting. As of March 29, that has not happened. For cryptocurrency markets, Polymarket's prediction contracts serve as on-chain derivatives allowing traders to hedge or speculate on geopolitical events. The significant volume and sharp odds shifts reflect market expectations and provide a unique data point for assessing risk sentiment.
