Elon Musk

With an estimated net worth of ~$400 billion, Elon Musk remains the wealthiest person on Earth by a commanding margin, outperforming #2 Jeff Bezos by $170 billion. His fortune spans Tesla, SpaceX, X (formerly Twitter), and xAI, the artificial intelligence company behind the Grok chatbot. His wealth surged dramatically after the 2024 US election as Tesla shares rallied and xAI closed a $6 billion funding round at a $50 billion valuation. Notably, Musk's net worth is more than double that of the typical runner-up in recent years, which averaged around $180 billion.
