I do not believe anyone can stream the current season Yellowstone. Peacock owns the streaming rights of their arch competitors, Paramount’s, top show. You can only watch live from paramount wherever you get the channel, cable, Hulu, etc.
If Yellowstone Ends This Year, It Will Have Lived, Died and Never Hit Paramount Plus
Paramount's biggest hit, counterintutively, doesn't stream on Paramount Plus -- and maybe never will.
