Which in turn owns Twitter. SpaceX is now a social media company in addition to a rocket company.

One theory I think Matt Levine posited, is that SpaceX will go public with dual-class stock that gives Elon control even with a minority ownership stake, and will subsequently buy Tesla, which doesn't have dual class stock, making SpaceX the singular "Elon Musk company", with him having operational control despite being public.

That theory aligns with Elon's long-held dream of X as the "Everything Company".
