Larry Page leads the market-implied odds for second-richest person on December 31 at 58%, ahead of Sergey Brin at 38.4%, reflecting Alphabet’s strong 2026 stock gains and AI-driven momentum in search, cloud, and Gemini ecosystem that have lifted both founders’ fortunes well above most peers. Recent Bloomberg and Forbes snapshots show Page and Brin clustered behind Elon Musk’s dominant lead but ahead of Michael Dell, Jensen Huang, and others whose valuations have lagged. Traders appear to favor Alphabet’s steadier trajectory over more volatile names, though final positioning hinges on year-end equity swings, earnings reports, and any late regulatory or competitive shifts that could reorder the billionaire rankings.
