Sony Pictures

Sony Pictures Studios owns the film rights to Spider-Man, and co-produces, finances, and distributes the Spider-Man franchise shared with Marvel Studios.

History
Sony is also developing its own standalone films (Venom and Silver & Black) separate from the deal with Marvel Studios, which have been confirmed by Amy Pascal (in a joint interview along with Kevin Feige with Fandom powered by Wiki) to exist "in the same reality" as "Spider-Man: Homecoming".
