Strong advance ticket sales and industry tracking estimates are fueling the 92.5% implied probability that Dunesday surpasses Barbenheimer’s roughly $244 million combined domestic opening weekend. Dune: Part Three has already generated franchise-record presales of about $10 million, putting it on pace for a $100 million-plus debut, while Avengers: Doomsday is tracking toward $260–300 million thanks to MCU momentum, Robert Downey Jr.’s return, and broad fan anticipation. These early indicators reflect the same kind of cultural event status that drove Barbenheimer, with both 2026 titles benefiting from IMAX demand and holiday timing. Still, audience overlap between the two blockbusters could split attendance, and any late shifts in marketing or reviews might temper the combined haul before December 18.

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.
