The Iranian regime's demonstrated resilience amid severe internal unrest and external military pressure drives the near-certain trader consensus against collapse by October 31. Despite protests spanning all provinces since late 2025, the deaths of Supreme Leader Ali Khamenei in a February 2026 strike, and subsequent leadership transitions, security forces have maintained cohesion without widespread defections, enabling rapid succession and continued suppression. Ongoing diplomatic initiatives and sanctions negotiations further signal institutional continuity rather than imminent breakdown. A sudden, nationwide elite split or coordinated military uprising could still shift outcomes in the narrow window, though historical patterns and current coercive capacity make such rapid change unlikely.
