Disney and Marvel Studios now have access to partnership would no longer continue.
Spider-Man leaving the MCU appear in both the MCU and Sony's villain universe.
This is a major victory for Sony as they look to build their own shared universe with the 900 Marvel characters they own the rights to. Sharing Spider-Man with Disney and Marvel Studios originally meant that they couldn't do this with their most recognizable character. They could have done so once the MCU deal collapsed, but Sony is now in a position where they will get the best of both worlds. Spider-Man's brand will grow larger with each subsequent MCU film, and Sony will then be able to boost their own Marvel films by putting him in them, without worrying about MCU continuity.
For Sony, this creates immense possibilities when it comes to creating their own cinematic universe. They've already successfully launched it with Tom Hardy's they plan to write Spider-Man out of the MCU during these two films. The best news for them is that they won't have to worry about making sure this story fits into the MCU or wipe Spidey clean of his MCU history - and they will do so without giving away half of their profits.
The financials were reportedly a big sticking point in early negotiations between Disney and Sony, with reports originally saying Disney called for an even split of financing and profits. Several reports from that point on showed a common ground between the studios of Disney co-financing Spidey's films at 25% and receiving that amount of the profits. According to Variety, this is the agreed-upon of the new deal. Once again, Sony managed to get the better end of the deal. They didn't lose Spider-Man's MCU connectivity and didn't fork over half of their biggest franchise to keep him.
At the end of this months-long Spider-Man drama, Sony got everything they could've wanted. They've managed to keep the rights to Spider-Man in a way where he is tied to the MCU but isn't pigeonholed to it. They did have to give Disney a larger cut of the profits on these films, but it was not as significant as a difference as what was originally reported. While fans will think they've won thanks to Spidey sticking with the MCU, it is really Sony who got the best end of the deal.
