The BBC thinks so. See their blog post titled The sci-fi genre offering radical hope for living better.
Annalee Newitz thinks Hopepunk is not a genre, saying that any story can have elements of hope.

A challenge to writing hopeful stories (or dystopian stories for that matter) is to do it without including too many “peanuts of pathos.” See Bloom County by Berke Breathed for details – dystopia at its finest.
