Mark Zuckerberg

Mark Zuckerberg saw his net worth hit $183 billion in 2025, up 40% from 2023, as Meta's stock soared on AI-driven ad revenue of $134 billion annually. His base salary remains $1 per year, but his 13% Meta stake is the real engine — that holding gained $50 billion in value in 2024 alone. Unlike #1 Elon Musk, whose wealth is tied to volatile Tesla equity, Zuckerberg's fortune is more stable due to Meta's mature cash flows. The metaverse bet through Reality Labs has cost $46 billion since 2021, yet AI tools now subsidize those losses: Meta's AI ad platform boosted click-through rates 22% year-over-year. He also spends $3 million yearly on personal security and trains in MMA, adding a distinctive public persona.
