Mark Zuckerberg has re-entered the world's top five richest people, riding Meta's best weekly stock performance since February 2024, a rally of more than 14 percent that added roughly 12.7 billion dollars to his fortune in a single day. He now sits behind only Elon Musk, Larry Ellison, Sergey Brin and Jeff Bezos, according to Bloomberg, though Forbes still has him a notch lower at sixth. The rally came from a flurry of AI announcements, including plans to mass produce Meta's own custom AI chip, named Iris, starting in September, alongside a roadmap to double computing capacity to 14 gigawatts by 2027. Meta has locked in supply deals with Samsung, SanDisk and Sumitomo Electric. Bank of America analyst Justin Post praised the chip strategy, and research firm SemiAnalysis called Meta the only mega cap company operating at world class levels across data, talent and computing power simultaneously. The company's new image generation tool Muse Image triggered a privacy backlash forcing a partial feature rollback. The stock had entered a correction earlier this year after a court ruling held the company liable for harming women's mental health through platform addiction, plus the quiet shutdown of its metaverse platform. Earnings are due July 29, with analysts eyeing a consensus price target of 827 dollars.
