It looks like that permanent magnet it's hovering over is a simple dipole magnet, rather than an array. A diamagnet would be unstable in that position. Look at any video of floating graphite and you'll see it hovering on top of a 2x2 array of magnets.

Of course, you could fake it for a video by buying a special disc magnet with a multipolar magnetization pattern, but magnets like that are pretty hard to find.

Putting a conspiracy cap on, is relatively easy to find a cover for an array that looks like a magnet

Though, so far, room temperature superconductors have been even harder.

If you already had a multipolar magnet for some reason, on the other hand, this wouldn't be too far fetched. You've got to think that with all the interest in this right now, the confluence of having access to a handy collection of peculiar magnets, knowing what to do with a bit of graphite, and being enough of a troll to publish a video, all in a single individual, isn't going to be that unlikely.
