It has to do abysmal for that to happen. And I don't see it.

Doctor Strange did 677 million world wide (232m domestic). Ant-Man & Wasp will probably end at 570-600m world wide (210m domestic).
Homecoming, Ragnorak, and Civil War all did 800m+... but they had prominent franchise characters teaming up to anchor it. Cap 3 was essentially Avengers 2.5 and did 1.1 billion... comparatively, Cap 2 did 715m world wide.
From the synopsis, Captain Marvel is a period piece that will be more along the lines of Cap 2, DS, and the Antman movies. i.e. (relatively) self contained.
So if it 'only' does 700 million world wide, the innantez will pounce on it because of what Black Panther (and Wonder Woman) did as relatively self-contained movies. But that wouldn't be a deal breaker behind the scenes, unless it does far lower than that.
