Marvel revealed release dates for eight MCU movies a few weeks ago that we associated with Phase 5. We’re looking at four films per year in both 2022 and 2023, although only one of them has a confirmed subject — that’s Black Panther 2, in May 2022. A well-known Marvel insider said at the time that Spider-Man 4 might be released in 2023, although a different report said the movie will not be part of the MCU. Instead, it’ll be included in Sony’s Spider-verse. More importantly, Daniel Richtman had this to say about Marvel’s 2023 Spider-Man plans:
If Captain Marvel 2 is Secret Invasion which is very likely then it’ll be the next crossover Spidey will take part in.
is the storyline that Marvel is rumored to be relying on to deliver the next Endgame-like movie, although the studio is far from confirming it despite multiple reports that this is the direction Marvel will be headed in.
As for 2023;
Feb – Blade
May – Captain Marvel 2
July – GotG Vol 3
Nov – Nova(?)
Also add Spidey 4 somewhere. If Captain Marvel 2 is Secret Invasion which is very likely then it'll be the next crossover Spidey will take part in.

With Captain Marvel and Far From Home, Marvel made it clear that Secret Invasion is a possible evolution of the MCU, so it makes some sense to see both Spider-Man and Captain Marvel involved in a movie that sets up the next Avengers. This would be the equivalent of what Captain America: Civil War did for Infinity War and Endgame. However, there’s no way of confirming any of this, even though Richtman does have a great track record at leaking MCU details.
Another rumor we can’t verify at this time says the Spider-Man deal is likely to be extended come 2022, in which case Marvel might use the hero in even more MCU films going forward. This comes from We Got This Covered, a site that features plenty of unverifiable rumors about Marvel’s Phase 4 and Phase 5 films.
