Strong presales for Dune: Part Three, including a franchise-best $10 million first-day domestic haul in mid-August 2026, have anchored trader conviction that the combined Dunesday opening will surpass Barbenheimer’s $244 million domestic benchmark. Dune benefits from exclusive IMAX screens for multiple weeks and sustained buzz from its recent trailer and ticket launch, while Avengers: Doomsday carries robust MCU tracking as a Phase Six tentpole. Holiday timing and franchise momentum further support the 91% implied probability for a Yes outcome. Realistic challenges include audience overlap between the two blockbusters, potential screen cannibalization, and any late shifts in tracking or marketing reception that could compress totals.

The "Daily Box Office Performance" figures found on the "Box Office" tab on these movies' The Numbers (https://www.the-numbers.com/) pages will be used to resolve this market once the values for each film's 3-day opening weekend (December 18 - December 20) are final (i.e., not studio estimates), then added together.
Please note, this market will resolve according to the The Numbers figures provided under Weekend Box Office Performance for the 3-day weekend (which typically includes Thursday's previews), regardless of whether domestic refers to only the USA, or to USA and Canada, etc.
If there is ambiguity as to whether the resolution source's figures are final, this market will remain open until both https://www.boxofficemojo.com/ and https://www.the-numbers.com/ have confirmed their finalized figures.
If both "Dune: Part Three" and "Avengers: Doomsday" do not both release on the weekend of December 18 - December 20, 2026, this market will resolve to "No". If both films release on that weekend but no final data is available by December 31, 2026, 11:59 PM ET, another credible resolution source will be chosen; if final data remains unavailable beyond February 28, 2027, 11:59 PM ET, this market will resolve to "No".
