Which movie has biggest opening weekend in 2026?

What this question means

Spider-Man: Brand New Day at 56%, Avengers: Doomsday at 45%, and nothing meaningful behind them across a four-film field.

The comparison worth making is with the highest-grossing question on this board, where the same film sits at 94%. Same year, same two contenders, and a very different picture — because one question is about a single weekend and the other about a full theatrical run.

Opening weekend is a volatile measure. It depends on screen count, release timing, marketing saturation and how front-loaded the audience is, and a film can win the opening and lose the year comfortably. Total gross smooths all of that out, which is why the crowd can be far more confident about it.

A near coin flip on the opening and a 94% on the year is not a contradiction. It says the crowd expects one film to have the stronger legs, while the launch itself is genuinely up for grabs.
