Decent summary of it here[0]. The “space” part of “SpaceX” is valued by market analysts and money managers at around 5% of the company’s entire value. Almost all of the rest is “AI stuff”, and Twitter is a rounding error.

That is, if SpaceX went back to being a space-only entity, and dropped the AI stuff, its share price should be expected to fall from $130/share to around $7/share.
