Michael Dell's net worth grew by $4.6 billion to an estimated $267.7 billion on Tuesday, driven by Dell Technologies stock rising 1.9% to a record close of $533.88. This surge, fueled by booming demand for AI hardware and strong Q2 earnings (revenue up 58% to $47 billion, AI server backlog at $95 billion), lifted him past Jeff Bezos ($265.2 billion) in Forbes' billionaire rankings. Dell now trails only Alphabet co-founder Larry Page ($277.9 billion) and Tesla chief Elon Musk ($942 billion).
