Which movie has biggest opening week in 2026?

Traders currently price "Spider-Man: Brand New Day" at 77% for "Which movie has biggest opening week in 2026?". Over the past 24 hours that probability moved down 2.0 points. Full distribution: Spider-Man: Brand New Day 77%, Avengers: Doomsday 24%, Toy Story 5 0%, Dune: Messiah 0%. The market has traded $63K in total volume and resolves Dec 31, 2026. Spider-Man: Brand New Day's record-shattering domestic opening of over $360 million in late July has established it as the clear frontrunner for the biggest 2026 opening week, backed by massive preview numbers and rapid global momentum that quickly made it the year's top earner. This performance outpaces earlier releases like Toy Story 5's $160 million June debut and creates a high bar for upcoming titles. Avengers: Doomsday holds secondary positioning ahead of its December 18 holiday slot, where strong tracking and franchise appeal could deliver a sizable weekend, though it faces direct competition from Dune: Messiah on the same date. The remaining options register minimal trader interest due to later or unconfirmed release windows and lower anticipated scale.
