It looks like this movie is a bona fide hit for Sony. With $205.2 million in the tank worldwide (with China still pending release), and with a total production budget of $116 million on the high end, adjusting about $40 million upwards for marketing costs, along with a 66%(-ish) take of the total cut from movie theaters, it looks the movie is days away from being in the black. It seems like Sony can rest assured that a universe of their own Marvel characters, even without Spider-Man, can perform well.
It seems unlikely Feige would be willing to let another company bring down the overall quality of his cinematic universe (31% on Rotten Tomatoes versus a startling high 65% for Thor: The Dark World) so Sony will probably be faced with the choice to leave Spider-Man out of a universe making money without him or to risk rebooting the character for the fourth time in twenty years, when reception for Spider-Man films hasn’t been this good since 2004. I think they’ll leave Peter Parker in the MCU at least until Feige decides he doesn’t care to tell stories with Spider-Man anymore. Still, hard to argue that part of what made Avengers: Infinity War a two billion dollar film was his inclusion. So, anticipate both studios to push forward with the deal as is. At least for long enough to get an MCU set trilogy.
