Elon Musk cofounded seven companies, including electric car maker Tesla, rocket producer SpaceX and artificial intelligence startup xAI.
He owns about 12% of Tesla, which he first backed in 2004, and which he's led as CEO since 2008. He also owns options to acquire another 8%.
Musk led a group that bought Twitter for $44 billion in 2022. He merged it with xAI in 2025 in deal that valued the combined company at $113 billion (net of debt).
SpaceX, founded in 2002, acquired xAI in February 2026 in a deal that valued the combined company at $1.25 trillion. Musk owns a nearly 40% stake.
Musk also founded tunneling startup The Boring Company and brain implant outfit Neuralink. The two startups have raised around $2 billion from private investors combined.
Musk, who says he's worried about population collapse, has fathered at least 14 children with four women, including triplets and two sets of twins.
As a kid in South Africa, Musk taught himself to code; he sold his first game, Blastar, for about $500.
