Will Dune 3 or Avengers: Doomsday gross more on their opening weekend?

Prediction markets put the probability at 5%: Will Dune 3 or Avengers: Doomsday gross more on their opening weekend. Currently, markets see this as unlikely (5% YES).

What’s Happening

The unprecedented same-day release of “Avengers: Doomsday” and “Dune: Part Three” on December 18, 2026 has created a singular box office showdown, with advance ticket sales already signaling a historic collision. Disney opened presales for “Avengers: Doomsday” four months in advance, generating $16.5 million in first-day domestic sales, a figure that notably excludes Imax premium screenings. Warner Bros. countered with its own aggressive presale campaign for “Dune 3,” leveraging the film’s status as the trilogy’s conclusion. The combined early demand has led industry trackers to project that the “Dunesday” weekend could rival the $402 million collective haul of 2019’s “Avengers: Endgame” weekend, making the question of whether dune 3 or avengers: doomsday gross more on their opening weekend a genuine toss-up in terms of fan enthusiasm, even if current market pricing heavily favors the Marvel title [Variety, Jul 21].

The competitive dynamics have already reshaped the broader release calendar. Sony moved “Jumanji 3” from December 11 to Christmas Day, explicitly citing the need to avoid the two-film behemoth’s opening frame. This strategic retreat underscores the perceived strength of both properties, but the market’s 5% probability for a “Dune 3” victory reflects a stark disparity in franchise scale. Marvel’s “Avengers” brand has a proven track record of opening weekends above $350 million globally, as seen with “Endgame” and “Infinity War,” while Denis Villeneuve’s “Dune” series, despite critical acclaim, has seen diminishing returns, with “Dune: Part Two” opening to $82.5 million domestically in 2024. TheWrap notes that even with strong word-of-mouth for both films, the MCU’s ability to draw lapsed fans back—particularly those who skipped “Thunderbolts” and “The Fantastic Four: First Steps”—creates a structural advantage that is difficult to overcome [TheWrap, Mar 23].

Looking ahead, the final determinant will be the first 48 hours of presales in the week leading up to release, particularly Imax and PLF screen allocations, which are expected to be split between the two films. Disney’s decision to open tickets 120 days in advance—versus the typical 45-day window used for “Spider-Man: Brand New Day,” which set a domestic record with $360 million—suggests confidence in sustained demand. However, Warner Bros. has reserved Imax screens for “Dune 3” in select international markets, a factor that could narrow the gap. The outcome of whether dune 3 or avengers: doomsday gross more on their opening weekend will be finalized on December 21, 2026, when Sunday estimates are released. Industry analysts are closely watching whether “Dune 3” can exceed $150 million domestically, a threshold that would make the race competitive but still leave it short of Marvel’s projected $250 million+ debut [Deadline, Mar 24].
