The Iranian regime's demonstrated resilience after the February 2026 U.S.-Israeli strikes, Supreme Leader Ali Khamenei's assassination, and earlier nationwide protests underpins the near-certain trader consensus against collapse by June 30. Security forces suppressed unrest by mid-January, maintained institutional control despite leadership losses, and continued crackdowns into June without signs of fragmentation or mass defections. With only days remaining before the deadline, the absence of any verified catalyst for rapid regime change—such as coordinated elite splits or uncontrolled uprisings—anchors the 99.2% implied probability on "No." While unforeseen military escalations, internal security breakdowns, or sudden opposition coordination could theoretically alter trajectories in the narrow window, these remain low-probability events given the regime's track record of enduring external and domestic pressure.
