There is definitely a mix of evidence from the people side of the equation. Rank amateurism mixed with well credentialed researchers. Check out this vid from EEVBlog highlighting one of the worst “amateur hour” parts: https://m.youtube.com/watch?v=QHPFphlzwdQ (tldr is that the main website shows a vid waving a magnet in front of a copper disk coated in their new material. The copper plate moves around because of Lenz’s law! Nothing to do with superconducting)

Meanwhile, the very well credentialed HyunTak clearly believes it’s real, but he was parachuted in late in the development.

Personally, I think we will just have to wait the week to see if this is real.
