Multiple independent observations lead to very solid evidence that dark matter exists. It’s a question of what comprises dark matter.
I personally like the solution of primordial black holes. Recent evidence from LIGO/Virgo and the Webb telescope are strengthening the possibility that most if not all dark matter is PBH.
This is a totally separate consideration from dark energy, though, just to be clear
