Bloomberg has just launched its Bloomberg Billionaire’s Index. Like Forbes, it professes to list the net worth of the world’s billionaires. Unlike Forbes and the others lists —and there are plenty others, from China’s Hurun Index, to the Times Rich List in the U.K. – the Bloomberg Index is updated daily. If you want to know what Warren Buffett or Carlos Slim or Larry Ellison is worth today, you can get it.
