The Walton family, founders of the world's largest company by revenue, Walmart, and the richest family in the world, just got a whole lot richer.

The family's fortune saw an $11.6 billion boost on Thursday morning after Walmart reported its best sales in a decade in the company's fiscal second-quarter earnings. This brings the family's collective wealth up to $163.2 billion, as of Thursday morning, and keeps the Waltons at the top of the Bloomberg's world's richest families list, at least $64 billion ahead of the next richest family's fortune.
