Amid escalating US-Iran conflict sparked by February's US-Israeli strikes killing Supreme Leader Khamenei, trader consensus on Polymarket prices a 77% implied probability for US forces entering Iran by December 31 and 69% by April 30, reflecting recent Pentagon preparations for weeks-long ground operations short of full invasion. Key drivers include yesterday's arrival of 3,500 Marines aboard USS Tripoli in the Middle East, deployments of 82nd Airborne paratroopers, and reports of up to 10,000 additional troops positioning for potential special operations raids on Iranian nuclear sites or Strait of Hormuz islands. Iran has warned of severe retaliation against any ground incursion, while Pakistan-hosted talks urge de-escalation; no boots-on-ground confirmed as of March 30, with March 31 market deadline looming.
