Bgger fortunes. More billionaires. Increasing impact. We mark the 10th anniversary of our annual list of America’s most successful self-made women by celebrating how far these 100 entrepreneurs have come: There are 38 billionaires this year, with fortunes originating in everything from cars to cosmetics to Chardonnay. That’s more than double the 18 we found in 2015. Minimum to make the cut? $350 million, up from $250 million a decade ago, when we only ranked 50 women.
