Which movie has biggest opening week in 2026?

What this question means

Avengers: Doomsday at 62%, Spider-Man: Brand New Day at 35% — and the ordering here is the reverse of the opening *weekend* question on this board, where Spider-Man leads 56% to 45%.

Same two films, same year, and the favourite flips depending on whether you count three days or seven. That is not an inconsistency; it is a precise statement about how the crowd expects each film to behave.

A film that opens enormous on Friday to Sunday and fades has a different shape from one that holds through weekdays. Front-loaded releases win weekends; films with broader appeal or stronger word of mouth gain ground across the full week. Pricing these two questions differently is the crowd saying exactly that.

Add the highest-grossing question, where Spider-Man sits at 94%, and you get a complete picture from three numbers: one film opens bigger over seven days, the other opens bigger over three and wins the year comfortably.
