Disney has been ass-blasted (and not in the fun way) recently, looking at the Box Office projections for Indiana Jones and it may well do even worse than The Flash.
DC is SUCH a big IP (Batman alone has made an insane amount pure profit over the years...) that I doubt Disney could afford it now, WB aint letting that go for cheap because as soon as they do its a sign the studio is dead.
My honest guess - Amazon may buy it or offer a merger of their entertainment divisions, they have the money and the ambition to both win the streaming wars and break out into full on award-winning cinema (though their track record leaves a lot to be desired, Rings of Power is basically eye-cancer and The Boys is the best thing on TV right now).
But if WB let loose that DC is up for sale (which is basically the same as WB announcing it has a terminal illness) ANY company with enough capital, or good enough credit to borrow, will put in a bid - governments will likely get involved due to the huge potential of a total monopoly of the industry, it would be a mess.
But to reiterate: money talks and Amazon are the money men.
