**Unprecedented advance ticket sales and franchise-scale anticipation are positioning "Avengers: Doomsday" for a potential record domestic opening weekend.** Disney confirmed over $50 million in domestic presales months ahead of the December 18 release, with trackers now estimating $65 million domestically and $100–125 million worldwide; more than 70% of early buys targeted premium Infinity Vision formats. The Russo brothers' return, Robert Downey Jr. as Doctor Doom, and a sprawling crossover featuring the Avengers, Fantastic Four, and X-Men have sustained strong trader sentiment, with bullish forecasts reaching $400–450 million. Competition from "Dune: Part Three" on the same weekend introduces some uncertainty, though current tracking suggests "Doomsday" will dominate the frame. Final marketing surges, including the global tour and holiday timing, remain key swing factors for whether the film clears or falls short of the all-time benchmark.
