Musk also owns a stake in The Boring Company. It just raised $3 billion at a $23 billion valuation. Musk owns 90% of the company. SpaceX owns 6%.

The Bloomberg Billionaires Index shows that Musk has gained or lost $100 billion in net worth in a week. The public’s interest is voyeurism. It means nothing beyond that. Musk could not spend the money in several lifetimes.
