January 8, 2026, 7:10 AM EST. Nvidia has been the standout beneficiary of AI infrastructure demand, underpinned by its dominance in data-center GPUs that power AI model training. A hypothetical $2,000 investment five years ago would be worth about $28,000 today, far ahead of the S&P 500's ~100% gain. Nvidia's revenue surged roughly 1,106% between Q3 2021 and Q3 2026, while profitability stayed strong with an average quarterly operating margin around 44%. The stock trades at a forward P/E of about 24.7. Analysts project continued top-line growth into fiscal 2028, though investors should weigh lofty expectations against valuation and the cycles of AI demand.
