Last year, Elizabeth Holmes topped the FORBES list of America’s Richest Self-Made Women with a net worth of $4.5 billion. Today, FORBES is lowering our estimate of her net worth to nothing. Theranos had no comment.
Our estimate of Holmes’ wealth is based entirely on her 50% stake in Theranos, the blood-testing company she founded in 2003 with plans of revolutionizing the diagnostic test market. Theranos shares are not traded on any stock market; private investors purchased stakes in 2014 at a price that implied a $9 billion valuation for the company.
