While 9-10 figure fortunes have greatly risen in China, the United States still dominates the top 10 rankings. The 2015 individuals and into the 2016 years’ billionaire top 10 list shown above, (29th annual ranking) is pretty similar to the same 10 richest people in the world identified in 2014. Lillian Bettencourt’s billionaire standing increased upwards, as well as many other entrepreneurial women who have broken the billionaire status. For instance, J.K. Rollings made $1 B with her books and movie deals. In addition to Liliane Bettencourt, Alice and Christy Walton, there are 20 global women (from $38B to $6.6B) who shape the list of top female billionaires, out of 187 women who are among the world’s wealthiest women.

As the Forbes list identifies a specific category, the “freshmen” class of billionaires will include many women and men with new technology ideas and inventions. Millenial billionaires are quickly joining the list of the top wealthiest sect, such as Mark Zuckenberg/Facebook; Dustin Moskovitz/Asana; Eduardo Saverin/Facebook and investor; Yang Huiyan/Country Garden Group; Scott Duncan/Enterprise Products, Evan Spiegel/Snapchat; Tom Presson/Hennes & Mauritz (“H&M”), Elizabeth Holmes/Theranos; and many other young self-made billionaires.

The list of the 10 richest people in the world denotes the billionaires who are business entrepreneurs. Jeff Bezos (founder of Amazon) will be on this list in 2016 for sure.  This Forbes list does not include royal family members or heads of state, as we have mentioned about Putin. Another new face on the list of the richest people in the world who are business magnates is mega businessman and former NBA player, Michael Jordan. Jordan qualifies because of his net worth of $1B, mainly due to his royalty deals, his ownership of the Hornets, and his varied business holdings. The next annual ranking of the 10 richest people in the world is going to be very interesting and is bound to be full of surprises.
