Forbes' 2026 Forbes 400 ranking shows a widening wealth gap among America's richest people, with the 400 members holding a combined $8 trillion. The top 20 account for half that total, which is $970 billion higher than in 2025. The entry threshold reached $4.4 billion, yet 34 newcomers joined the list while 590 other American billionaires fell below the cutoff. Elon Musk ranked first for the fifth straight year with $908 billion, becoming the first person to exceed $900 billion on the list. Amazon founder Jeff Bezos ranked second with $378 billion, more than $500 billion behind Musk.
