Spider-Man: Brand New Day is part of Phase Six of the Marvel Cinematic Universe.
The MCU divides its films and television projects into broad narrative eras called phases. Brand New Day follows the Phase Five period and belongs to the next group of Marvel Studios stories.
The film continues the MCU’s version of Peter Parker after Spider-Man: No Way Home. Its story begins with Peter living anonymously after the world forgot his identity, making it a continuation of the previous Spider-Man trilogy rather than a separate non-MCU reboot.
Phase Six also includes major MCU projects planned around the Avengers storyline. Brand New Day therefore occupies an important place in the MCU’s post-Multiverse Saga release schedule.
