It is the first time Gates has held the mantle since 2007. His fortune is valued at $72.7 billion, up 16 percent year-to-date. At the same time, Mr. Slim’s América Móvil, the largest mobile-phone operator in the Americas, has dropped 14 percent this year after Mexico’s Congress passed a bill that could quash the billionaire’s market dominance. That’s helped erase more than $3 billion from the tycoon’s net worth. What comes to Bill Gates, most of his fortune is held in Cascade Investment LLC, a holding entity through which he owns stakes in more than a dozen publicly traded companies and several closely held operations. He has donated $28 billion to the Bill & Melinda Gates Foundation.
