This is domestic calendar gross in 2026 per Box Office Mojo. Doomsday opens in December, so it has only about two weeks of 2026 domestic gross to overtake films that grossed all year. A huge Marvel opening is plausible, but beating the full-year domestic leader in two weeks is unlikely.

Box Office Mojo's 2026 calendar-gross leader is Spider-Man: Brand New Day at ~$959M domestic. Avengers: Doomsday opens Dec 18, 2026, leaving only ~2 weeks of 2026 calendar gross; even record openings (Endgame ~$620M in ~2 weeks) fall far short of $959M. Near-impossible barring data quirks.
Source 1 ↗ Source 2 ↗Spider-Man: Brand New Day already has approximately $959 million in the required domestic calendar table. Doomsday's December 18 opening gives it only fourteen days through December 31 to exceed that. Endgame earned $660.4 million in its first fourteen days. Higher ticket prices, holiday attendance and exceptional demand create an upside tail, but surpassing $959 million that quickly remains unlikely. Worldwide and eventual full-run totals do not count.
