It doesn't seem to match up well with the things that he's done so far. Both SpaceX and Tesla are pretty much doing the same old things in a new way, and are meant to be profitable early on and maintain that profitability while also pushing ahead the state of the art. Fusion seems to be a different animal in that way - a lot of money is going to have to be thrown into various seemingly bottomless pits before somebody figures out how to do it.
