Sony began developing a sequel to Into the Spider-Verse prior to its 2018 release, with the writing and directing team attached. It was set to focus on the relationship between Moore's Miles and Steinfeld's Gwen. The sequel was officially announced in November 2019 and animation work began in June 2020, with a different visual style for each of the six universes visited by the characters.

Spider-Man: Across the Spider-Verse premiered at the Regency Village Theatre in Los Angeles, California on May 30, 2023, and was theatrically released in the United States on June 2, having been delayed from its original April 2022 theatrical release date due to the COVID-19 pandemic.
