You'd better hope.\ You had better hope. => (roughly corresponds to) => You should hope. https://dictionary.cambridge.org/grammar/british-grammar/had-better

The above answers are good. "I'll have the money I owe you by next Monday!!" "You better hope so, or I'll . . ." Oftentimes, colloquially, the "so" is omitted. "You better hope" is perhaps an abbreviation of "you better hope that it is so" or "you better hope that it turns out this way." As already mentioned, the context is sometimes in the context of force or adverse consequences. Best wishes for you studies.

Yep, agree with Michael. Bad English for "you'd better" and quite threatening. It implies that: you had better hope that's true, because if it isn't there will be consequences.

It's a little bit of a threat, in bad English
