Which movie has biggest opening weekend in 2026?

Resolution Criteria

This market will resolve according to the title of the movie which grosses more domestically on its opening weekend than any other movie in 2026. The “Weekend Box Office Performance” table on the page for the relevant movie on https://www.the-numbers.com/movies/year/2026 will be used to resolve this market once the values for the 3-day opening weekend are final (i.e. not studio estimates). This market will resolve to "Yes" if the relevant movie grosses more on its 3-day domestic opening weekend than any other movie in 2026. Otherwise, this market will resolve to "No". Please note, this market will resolve according to the The Numbers figures provided under Weekend Box Office Performance for the 3-day weekend, regardless of whether domestic refers to only the USA, or to USA and Canada, etc. Resolution will be based specifically on the figures provided for this movie's 3-day opening weekend (Friday, Saturday, Sunday), regardless of whether the movie has a 4 or 5-day opening weekend. If another movie's opening weekend box office performance surpasses that of the named movie after numbers for both are finalized, this market may immediately resolve to "No". If this movie's opening weekend box office performance ties with any other's, the movie whose title comes first in alphabetical order will win. If there is no final data available by January 31, 2027, 11:59 PM ET, another credible resolution source will be chosen.

Avengers: Doomsday is the heaviest-backed contender to record the biggest domestic opening weekend of 2026 in Polymarket trading, with the market strongly concentrated on that single outcome. Spider-Man: Brand New Day is the second most heavily backed title. Resolution is determined by finalised three-day domestic opening weekend gross figures from The Numbers, with a deadline of 31 December 2026.

Market structure

The market covers 27 named film titles, with trading volume overwhelmingly concentrated on one outcome: Avengers: Doomsday. Spider-Man: Brand New Day is a distant second, and all remaining titles — including Toy Story 5, Dune: Messiah, The Odyssey, and The Hunger Games: Sunrise on the Reaping — attract marginal volume. Resolution uses finalised three-day domestic opening weekend figures from The Numbers. An alphabetical tiebreaker applies in the event of identical gross figures.

Background

The domestic opening weekend record is one of the most closely watched metrics in the film industry, reflecting a studio's marketing reach, franchise strength, and audience anticipation. The current all-time domestic opening weekend record is held by Avengers: Endgame (2019). The 2026 release calendar is unusually loaded with tentpole sequels and franchise instalments across Marvel, Star Wars, Nintendo, and legacy properties. Marvel Studios films have dominated the upper end of the all-time domestic opening weekend chart, and Avengers: Doomsday is positioned as one of the most commercially significant releases in the Marvel Cinematic Universe's recent history, marketed as a convergence of multiple ongoing storylines. The competitive landscape in 2026 means several films could plausibly challenge for the annual record, though the spacing of release dates and franchise momentum will be decisive.

Key factors

The primary factor driving resolution is the release schedule: a film's opening weekend total is heavily influenced by how many competing titles are released in adjacent weeks, the time of year (summer and holiday windows typically produce larger grosses), and whether a film faces direct competition from another major franchise. IMAX and premium large-format screen allocation can meaningfully affect three-day totals, as can audience tracking in the weeks before release. For Avengers: Doomsday specifically, the MCU's post-Endgame trajectory and the reception of preceding films in the same narrative cycle will influence audience appetite. Spider-Man: Brand New Day's performance will depend in part on how its storyline connects to prior instalments and whether it attracts both casual and dedicated audiences. For any title, poor critical reception or late-breaking controversy can suppress opening weekend performance even for heavily anticipated releases. The finalisation of studio-reported figures versus estimates can also shift rankings marginally.
