Amazon.com founder Jeff Bezos made a fortune on top of his existing fortune Wednesday and finished the day as the second-richest person on the planet. His company's share price surged $9 billion after its purchase of Middle Eastern e-commerce site Souq, adding $1.5 billion to Bezos' personal wealth, enough to have paid for his purchase of the Washington Post six times over, CNN reports. According to Bloomberg's billionaires list, Bezos is now worth $75.6 billion, second only to Bill Gates, who is worth an estimated $86 billion. The stock bump shifted Bezos up from fourth place on the list, knocking investor Warren Buffett and Spanish fashion tycoon Amancio Ortega down a notch.
Bezos has now added more than $10 billion to his net worth this year, and Wednesday was a good day for him in more ways than one, Gizmodo reports. Amazon announced that it was shutting down Quidsi, which operates sites including Diapers.com. It bought the firm for $545 million in 2010 after a price war—and a feud with founder Marc Lore. Lore went on to found "Amazon killer" Jet.com, and now runs e-commerce operations for Walmart, which bought Jet.com last year. It might seem unlikely that Bezos shut down the firm his rival founded as a "personal vendetta or some level of gamesmanship ... but it has been easy to find people who know both companies well that won't rule out the possibility," Jason Del Rey writes at Recode.
