“There are two factors to consider here, with the first being the fact that it is unclear what version of Spider-Man would appear in this film. While it could be the Spider-Man from the Marvel Cinematic Universe, who is played by Holland, it could also be an alternate Peter Parker entirely (who just happens to be Tom Holland). Since Marvel Studios is not producing this movie, it is quite possible this Spider-Man in ‘Venom 2’ has nothing to do with the MCU.
The second factor is contingent on the first. So, if the MCU’s Spider-Man appears in ‘Venom 2,’ does that make the first and second ‘Venom’ films canon to the Marvel Cinematic Universe? This is also unclear, but at the same time unlikely given what we do know.”
