The later company record
Sony's fiscal-2021 third-quarter presentation described Spider-Man: No Way Home's December 17, 2021 US release and reported worldwide box-office revenue of approximately $1.7 billion at the presentation's cutoff. That is a later cumulative snapshot than the initial headline about passing $1 billion.

Crossing a billion dollars means exceeding a threshold, not stopping there. A subsequent report can give a larger correct total because more tickets have been sold or more markets included. Compare the reporting date and territory definition before assuming the figures conflict.
Worldwide ticket gross is also different from profit or the number of individual viewers. The same person may buy several tickets over repeated visits, as the related Ramiro Alanis record illustrates. This article does not supply a current lifetime total or a new box-office ranking; it preserves the historical milestone using the studio's later financial record.
