Spider-Man: Brand New Day’s record-shattering theatrical run positions it as the clear frontrunner for 2026’s highest-grossing film, with traders assigning it an 85% implied probability. The July 31 release delivered the biggest domestic opening weekend ever at $360 million, a $932 million global debut, and a current worldwide total exceeding $2.52 billion, outpacing every other 2026 title by more than $700 million. Strong legs, international strength, and its status as the highest-grossing Spider-Man film ever have locked in a substantial lead. Avengers: Doomsday holds the next-highest odds at 14.6% on the strength of robust presales ahead of its December 18 release, yet the remaining calendar window and the existing gap make an overtake unlikely absent unprecedented legs. Most other listed titles have already finished their runs well below the leader.
