Strong presales momentum, with domestic advances exceeding $65 million and global totals surpassing $125 million roughly 46 days before the December 18 release, anchors trader consensus around the 360-400 million domestic opening range. These figures outpace prior MCU benchmarks at equivalent points and approach records set by Spider-Man: Brand New Day and Avengers: Endgame, fueling expectations for a massive debut driven by Robert Downey Jr. as Doctor Doom, returning Avengers stars, and early Infinity Vision ticket sales. Conservative trackers project 260-300 million while aggressive estimates float 400 million-plus potential, tempered by the same-day clash with Dune: Part Three and typical late-cycle presale cooling. Final weeks of marketing, preview tracking, and any early critical signals will likely determine whether momentum sustains the frontrunner positioning.
