As I wrote in the piece, I'm extremely skeptical that xAI should be valued as if it is a frontier lab.
But as you say, going back to the xAI + SpaceX merger, analysts consistently seem to value it as if it is, so I predict the public will too, at IPO time.
I assume "extremely skeptical" is you being generous, is there anybody other than Elon who says xAI/Grok are SOTA? The only thing anybody says about it is that it's only good for porn, but local models do porn too so xAI has no moat or edge at all as far as I can see.
