Sony and Disney have made a deal, Spider-man will remain in the MCU.


Knower of Stuff
I've seen one current theory that says that this is so Marvel can write Spider-Man out of the MCU. Though if Apple buys Sony, it's said that Spider-Man rights revert to Marvel/Disney. This could also be a set up for the Multi-Verse, Spidey style.

Or I could be completely wrong on all accounts.
