Michael Rubin — Net Worth and Career Earnings
Michael Rubin has an estimated net worth of $12 billion as of 2026, driven primarily by his ownership stake in Fanatics — the sports commerce platform valued at $31 billion. The Conshohocken entrepreneur started his first business at age 12 and built GSI Commerce into a leading e-commerce services company before selling it to eBay for $2.4 billion in 2011, retaining the sports licensing business that became Fanatics. Fanatics has since acquired Topps trading cards and launched Fanatics Betting and Gaming. His REFORM Alliance co-founded with Jay-Z, Robert Kraft and Meek Mill is a leading criminal justice reform organisation. His annual white party at Super Bowl week is one of sports' most exclusive events.
