Nvidia posted approximately 15,333% in total returns over the past ten years, the top figure in every S&P 500 performance ranking ever assembled. Through the first half of 2026 the stock gained 7% to 8% year-to-date, trailing both the broader market and the PHLX Semiconductor Sector Index.
Nvidia posted approximately 15,333% in total returns over the past ten years, a figure that lands it at the top of every S&P 500 performance ranking ever assembled. A $10,000 stake left untouched a decade ago would be worth roughly $1.5 million today. The company builds the graphics processing units that power the AI infrastructure buildout, both for training large language models and for running inference workloads at scale.
One company supplied a sixth of the index return
In 2025, Nvidia accounted for roughly 15.5% of the S&P 500’s total return of 17.9% — nearly one out of every six dollars the index made last year came from a single company. Its market weighting inside the index sits at approximately 7.94% to 8%, making it one of the heaviest anchors in the entire S&P 500.
That position traces back to a pivot that looked risky at the time. Nvidia sold gaming GPUs before the machine learning community discovered that the same parallel processing architecture suited the math behind neural networks, and demand exploded.
Competitors have been trying to close the gap ever since. AMD has made real progress, Intel has attempted several reinventions, and custom silicon projects from Google, Amazon, and Microsoft are live in production. None of them have materially dented Nvidia’s share of the AI training market.
2026 turns into a reality check
Through the first half of 2026, Nvidia’s stock gained 7% to 8% year-to-date, trailing both the broader market and the PHLX Semiconductor Sector Index. At issue is not the business but the AI capital expenditure cycle, which drove hyperscaler GPU orders to extraordinary levels and may be entering a phase where efficiency matters more than raw compute expansion.
If the big cloud providers start squeezing more out of existing hardware rather than ordering new racks, Nvidia’s revenue growth rate slows. Export restrictions on advanced chips to certain markets have also been a recurring headwind, and any tightening of those rules lands directly on Nvidia’s addressable market.
Meanwhile, the Roundhill Magnificent Seven ETF has returned 158% since its April 2023 launch. The fund has fallen 4% in 2026 while the S&P 500 gained 8%. Nvidia remains the dominant AI chip supplier, yet investors debate how long today’s extraordinary demand can continue as customers eventually digest their purchases.
