The vast majority of Elons wealth is in Tesla shares. He has about 20% of tesla shares. Tesla is nearly always in the top 10 most valuable companies in the world.

If Elon Musk is good at one thing its self promotion and hype. Tesla valuation is based on pure Hype and BS. E.g. FSD, 40k Cybertruck, Floating Roadster, 20 million cars a year by 2030 etc etc.
If it was based on actual business metrics it's valuation would be 10 times smaller
