I was familiar with the Forbes 400, but not this index of billionaires worldwide.
Carlos Slim tops the list with 72.7 billion
Bill Gates is second at 63.5 billion
Warren Buffett is third at 45.5 billion
Barely ahead of Amancio Ortega Gaona at 45.1 billion
Surprisingly Larry Ellison is not far behind at 40.0 billion and could easily overtake Buffett should ORCL continue to outperform BRK.A.
Looking at the 2010 Forbes 400 list, Buffett was comfortably ahead of Ellison 45 to 27. Then again, in 2000, it was Ellison 58, Buffett 28.
And now I see that Forbes has their own list of billionaires and lists Bernard Arnault fourth at 41B. Arnault is 15th on the Bloomberg list at 25.0 billion.
