Musk's Wealth Hits 2022 Low in 48% Plunge From $340 Billion Peak

While Elon Musk tinkers with newly acquired Twitter, his net worth has dropped by almost half from last year’s peak.

Shares of Tesla Inc., the electric car maker that comprises the bulk of his fortune, traded as low as $186.75 intraday Tuesday as investors question whether the billionaire is spreading himself too thin among his many high-profile ventures. Tesla is down 45% this year, compared with the 19% drop of the S&P 500 Index and the 32% decline of the tech-heavy Nasdaq 100 Index.
