Take it with a huge grain of salt, as it comes from unverified sources such as DanielRPK (you can check the interwebs if you want to read yourself).
Marvel and Sony are again renegotiating the terms of the Spider-Man deal. The new deal would have Tom Holland reprise the role for 6 more appearance, Spider-Man 4, 5, 6, Doomsday, Secret Wars, and an unnamed movie). The deal would also allow Marvel to use more of the villains in the MCU once Sony has used them in their films. There was also talk about Marvel getting a larger cut of the Sony films as they will be made under the Marvel Studios banner, but that one I'm less likely to believe.
We'll see how much of that is true if the deal becomes public, but if this is true that means Sony is really running on empty with their Spiderverse.
