Elon Musk Extends Lead as World’s Richest Person with Net Worth at $684.3 Billion

Elon Musk has retained his position as the world’s richest individual, with his real-time net worth climbing to $684.3 billion as of December 17, 2025. His wealth has expanded sharply in recent years, placing him far ahead of other global billionaires and marking a historic gap between Musk and the rest of the world’s richest individuals.

Musk’s fortune is driven by his stakes across multiple high-profile companies he co-founded, including Tesla, SpaceX, and artificial intelligence firm xAI. SpaceX, now valued at around $400 billion, remains a major contributor to his net worth, while Tesla continues to play a key role despite regulatory and legal challenges related to executive stock options. His business portfolio also includes X (formerly Twitter), Neuralink, and The Boring Company, highlighting his broad influence across electric vehicles, space technology, artificial intelligence, and emerging infrastructure ventures.
