Spider-Man: Brand New Day’s record-shattering run since its July 2026 release underpins the market’s overwhelming 95.5% implied probability. The Tom Holland-led Marvel title delivered the biggest domestic opening ever at $360 million, crossed $2.5 billion worldwide by early October, and already ranks as the year’s clear leader and third-highest grosser of all time. Strong word-of-mouth, franchise loyalty, and international appeal have produced exceptional legs and multiple all-time benchmarks. Avengers: Doomsday remains the only realistic upset scenario if it launches explosively late in the year and sustains unprecedented momentum, though the current $2.5 billion-plus gap makes that outcome highly improbable based on current tracking and historical precedent.
