The answer to this is a complex "web" of legal rights that spans both companies. In terms of Theme Parks, Spider-Man is Universal in the Eastern United States and Disney elsewhere. Due to a 1994 contract, Universal has the exclusive "perpetual" rights to use most major Marvel characters (including Spider-Man) in theme parks east of the Mississippi River, which is why The Amazing Adventures of Spider-Man is a flagship ride at Universal Orlando. However, at Disneyland in California and Disneyland Paris, Disney has built Avengers Campus featuring the WEB SLINGERS: A Spider-Man Adventure ride. In terms of Movies, Spider-Man is owned by Sony Pictures, but he appears in the Marvel Cinematic Universe (MCU) through a unique partnership deal between Sony and Disney. As of 2026, Sony still holds the theatrical rights and recently announced plans to reboot their "Spider-Verse," while Disney-owned Marvel Studios continues to produce the Tom Holland-led films. Essentially, you watch him in Disney movies, but you visit him at Universal if you're in Florida.
