Where does his fortune come from?
Zuckerberg owns about 13% of Meta economically. That direct link means Meta share-price moves translate almost directly into his paper net worth.
He does not rely mainly on salary or outside assets. When Meta rises, his wealth rises fast, and when Meta falls, his wealth drops by billions in the same trading session.
Why do Forbes and Bloomberg disagree?
Forbes' Real-Time Billionaires list put Zuckerberg at about $246.7 billion in late September 2026, according to Billionaires.Africa's summary of Forbes data. Bloomberg's index valued him higher at roughly $258-$262 billion in the same period, according to Inc.'s report on the Bloomberg index.
The gap reflects different valuation methods and update timing, not different assets. Readers comparing lists should check the same points:.

Why did his wealth swing so fast?
Days before the drop, he gained about $25 billion in one day to $253.6 billion, according to Mint's report on the one-day gain. Meta shares surged nearly 12% on AI optimism.
He then lost nearly $20 billion across two trading days, according to Mint's report on the two-day loss. The reported loss was $8.9 billion Friday plus $10.9 billion Monday after a Goldman Sachs note questioned Big Tech AI infrastructure spending.
What does his Meta stake control?
Zuckerberg holds nearly all Meta Class B super-voting shares. Those shares give him about 60.8-61% voting control despite only about 13-14% economic ownership.
That structure lets him set company direction even when most capital belongs to other shareholders. For readers checking "how rich now," these are real-time estimates that change daily with Meta stock, so consult the live Forbes or Bloomberg tracker rather than a fixed number.
