Gates--still No. 1.
Gates, the co-founder and former CEO of Microsoft, topped the list--again--with an estimated wealth valuation of $54 billion. Second on the list was Berkshire Hathaway CEO and Gates pal Warren Buffett with $45 billion. Rounding out the top three was Oracle CEO Larry Ellison with $27 billion.
Tied at No. 11 on the list were Google co-founders Larry Page and Sergy Brin with net worths of $15 billion. They were followed by No. 15 Dell CEO Michael Dell ($14 billion), No. 16 Microsoft CEO Steve Ballmer ($13.1 billion), No. 17 Microsoft co-founder Paul Allen ($ 12.7 billion), and No. 18 Amazon CEO Jeff Bezos ($12.6 billion).
The intrigue comes much lower on the list, where Zuckerberg, who didn't even make the list last year, ranked higher than Jobs, who founded Apple some eight years before Zuckerberg was even born. No. 35 Zuckerberg ($6.9 billion) got a boost last year from a $200 million infusion of cash in his social-networking titan. Despite Apple recently passing Microsoft in valuation, the majority of No. 42 Jobs' ($6.1 billion) net worth comes from his shares in Disney, which bought his Pixar animation studio in 2006 for $7.4 billion.
Following in tech's tradition of philanthropy, Zuckerberg is expected to announce a $100 million donation to the Newark, N.J., school district during an appearance on the Oprah Winfrey show Friday.
Rounding out the top 100 where No. 47 eBay founder Pierre Omidyar ($4.3 billion), No. 48 Google CEO Eric Schmidt ($5.4 billion), No. 51 EchoStar CEO Charles Ergen ($5.2 billion), and No. 88 Intel co-founder Gordon Moore ($3.5 billion).
