Amazon’s Decade-Long Bull Run Outshines S&P 500, Narrows Gap With Microsoft and Alphabet

A $100,000 investment in Amazon stock a decade ago would now be worth approximately $754,155, reflecting a total return of 654.16% and a compound annual growth rate of 22.4%. This performance more than doubles the S&P 500's returns over the same period, which would have grown the same investment to between $310,000 and $330,000.

The surge was fueled by Amazon's 20-for-1 stock split in June 2022, which broadened retail access, and the meteoric rise of Amazon Web Services (AWS) as both a profit engine and AI infrastructure leader. AWS reported 28% year-over-year revenue growth in Q1 2026, its fastest pace in years.

While Amazon's returns dominate broader indices, the race against Microsoft and Alphabet remains surprisingly tight—a testament to Big Tech's collective resilience. The comparison underscores how structural advantages and scalability continue to reward long-term investors in sector leaders.
