Mark Zuckerberg — $220 Billion

Meta CEO Mark Zuckerberg saw his net worth climb to roughly $220 billion in 2025 as Facebook, Instagram, and WhatsApp collectively served over 3.5 billion monthly active users. Meta's AI investments, particularly its Llama open-source model family and AI glasses partnership with Ray-Ban, positioned it as a leader in consumer AI.
