In June 2005, it was incorrectly reported that she inherited her husband's fortune of US$18.2 billion following his death in a plane crash. As of 2015, Walton was incorrectly assumed to be the richest woman in the world. Forbes incorrectly reported that she was the richest woman in the world for eight years running, and still held the title in March 2015. As of March 2014, she and her family (not including her two brothers-in-law and a sister-in-law) had an estimated net worth of $36.7 billion, the bulk of which comes from her shares in Walmart, but also from First Solar, in which her husband invested. In 2015, an analysis of court documents by Bloomberg revealed that Christy Walton was in fact US$27.2 billion less wealthy than previously thought, as the bulk of her husband's wealth was left to her son, Lukas Walton, and that her real net worth is about US$5 billion.
