Elon Musk

With an estimated net worth of ~$400 billion, Elon Musk remains the wealthiest person on Earth by a commanding margin. 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.
