Trader consensus on Polymarket places Larry Page as the slim frontrunner at 31% implied probability for second-richest person by December 31, just ahead of Warren Buffett's 29%, reflecting Alphabet's recent stock surge of over 5% in the past week amid strong AI earnings momentum and cloud growth reports. Brin trails closely at 25.5% due to his slightly smaller stake, while Zuckerberg's 24% bid hinges on Meta's volatile ad revenue trajectory despite platform expansions. Buffett's steady Berkshire Hathaway underpins his position, buffered by diversified holdings against tech swings. With only weeks until year-end stock closes, key differentiators include final-quarter earnings beats, Fed rate signals, and no major asset sales announced, leaving room for volatility-driven upsets among this elite pack of billionaire icons.
