* There was a planned Spider-Man 4: Back in the day, Sam Raimi was set to direct a fourth Spider-Man film with Tobey Maguire. However, it was canceled in 2010.
* "Spider-Man 4" isn't being made now: There are no official plans for a direct sequel to the Raimi trilogy.
* Spider-Man: No Way Home is a kind of spiritual successor: The recent film brought back elements and characters from the Raimi movies, so some fans consider it a "soft" sequel.
* The future of Spider-Man is uncertain: With the MCU Spider-Man films, anything is possible. There could be future films that borrow elements from the Raimi trilogy, but it won't be a direct continuation.
So, is Spider-Man 4 real? Not in the way we were expecting. It's a project that was planned but ultimately scrapped. While there are nods to the Raimi trilogy in later films, there's no current movie called "Spider-Man 4."
