Highest grossing movie in 2026?

Platform comparison

Market context

The 2026 domestic race is currently being framed as a two-horse contest between *Spider-Man: Brand New Day* and *Avengers: Doomsday*, with the former already carrying the clearest lead in trader pricing and most analyst-style forecasts. Polymarket’s event page shows *Spider-Man: Brand New Day* around 74%–91.5% implied probability, while a Covers summary of Polymarket data put it at 67% in late June, and the wider market has repeatedly placed it ahead of the rest of the field; by contrast, the contract on this venue is marked at 0% YES, indicating a sharp divergence between platforms.[11][2]

That gap matters because historical box office winners usually come from films with either exceptional franchise pull or a long run of release dates that lets them accumulate domestic gross through year-end. Current prediction lists and box-office commentary cluster around the same titles — *Spider-Man: Brand New Day*, *Avengers: Doomsday*, *Toy Story 5*, *The Super Mario Galaxy Movie* and *The Odyssey* — but they disagree on how wide the gap will be, with some forecasts putting *Avengers: Doomsday* above $1.6 billion worldwide and others still backing *Spider-Man* as the more dependable domestic accumulator.[1][8][18]

For traders, the main catalysts are release-date changes, trailer reception, and whether any competing tentpoles slip into late 2026 or push into 2027. The key dependency is calendar timing: because settlement uses 2026 domestic grosses only, an earlier release with sustained playability has a structural advantage over a bigger film that arrives late. Box-office coverage from Variety and market commentary both point to the same live issue — whether *Spider-Man: Brand New Day*’s release timing and franchise momentum are enough to preserve its lead, or whether a late-year surge from *Avengers: Doomsday* or another family title narrows the gap.[17][11]
