Nvidia, Micron and Other 5 S&P 500 Stocks With +100% Revenue Growth

Doubling revenue in a year is rare for any company. For an S&P 500 member, it’s even more unusual. Yet seven companies in the index are doing it right now, with each reporting quarterly sales at least twice as high as a year earlier. Six are selling the physical infrastructure behind the AI boom — from memory chips and lasers to power systems and testing equipment. The seventh makes laboratory instruments, and its surge has a very different explanation. Here’s a ranking of the seven fastest-growing S&P 500 stocks by revenue as of October 2026: 7. Teradyne Inc. (NASDAQ:TER): +104.0% The North Reading, Massachusetts-based company builds the machines that test chips before they leave the factory. Every AI processor and every memory stack must pass through one. Revenue in the second quarter of 2026 reached a record $1.33 billion. The stock is up 116% this year. Teradyne reports third-quarter results on Oct. 27. Analysts expect revenue of $1.26 billion, up 64% from $769 million a year earlier, with earnings of $2.08 per share. 6. Nvidia Corp. (NASDAQ:NVDA): +105.9% Revenue in its fiscal second quarter of 2027, which ended in late July, hit $96.22 billion. That is roughly $49 billion more than a year earlier. In other words, Nvidia added in one quarter more sales than most S&P 500 companies generate in a full year. The Santa Clara, California-based company reports fiscal third-quarter 2027 results on Nov. 25. Analysts expect revenue of $108.8 billion, up 91% from $57 billion a year earlier, and earnings of $2.47 per share. That would be Nvidia’s first quarter above $100 billion. 5. Lumentum Holdings Inc. (NASDAQ:LITE): +109.3% San Jose, California-based Lumentum makes lasers that move data as light between AI servers. Light travels faster and wastes less energy than electricity over copper wire. Its newest 200G lasers are sold out. Revenue in the fiscal fourth quarter of 2026, which ended in June, more than doubled and crossed $1 billion for the first time at $1.01 billion. The stock is up 199% this year. Lumentum reports fiscal first-quarter 2027 results on Nov. 5. Analysts expect revenue of $1.25 billion, up 134% from $534 million a year earlier. The expected profit is $4.21 per share. Add article title and URL 4. Waters Corp. (NYSE:WAT): +113.3% Waters is the exception in this list. It makes instruments that pharmaceutical labs use to measure chemicals and test drugs. Its revenue in the second quarter of 2026 more than doubled to $1.65 billion, mainly because it absorbed businesses acquired from Becton, Dickinson and Co. The core business grew 9% organically. The stock is up 15% this year. Milford, Massachusetts-based Waters reports third-quarter results on Nov. 3. Analysts expect revenue of $1.75 billion and earnings of $4.00 per share. 3. Bloom Energy Corp. (NYSE:BE): +165.5% Bloom sells fuel cells that let data centers produce their own electricity. As the power grid struggles to keep up with AI demand, that has become a real business. Revenue in the second quarter of 2026 rose by 165.5% to $1.07 billion. The San Jose-based company raised its full-year target to $3.9 billion–$4.2 billion, and Oracle plans to use up to 2.8 gigawatts of its fuel cells. The stock is up 227% this year. Analysts forecast revenue of $1.06 billion, up 104% from $519 million a year earlier, and earnings of $0.68 per share. 2. Sandisk Corp. (NASDAQ:SNDK): +371.6% AI data centers depend on NAND flash — Sandisk’s specialty — and supply is tight. As a result, revenue in the fiscal fourth quarter of 2026 jumped by 371.6% to $8.96 billion. The stock is up 580% this year, the best-performing name in the S&P 500. Milpitas, California-based Sandisk reports fiscal first-quarter 2027 results on Oct. 29. Analysts expect revenue of $10.6 billion, up 361% from $2.31 billion a year earlier, and earnings of $46.11 per share. 1. Micron Technology Inc. (NASDAQ:MU): +379.3% Boise, Idaho-based Micron sold $54.23 billion in its fiscal fourth quarter of 2026, which ended in late August. A year earlier, it sold $11.32 billion. That is nearly five times more in twelve months. The driver is high-bandwidth memory, the fast memory placed right next to every AI chip. Gross margin reached 86.8%, meaning Micron kept almost 87 cents of every sales dollar after production costs. The stock is up 254% this year. Micron’s next report, for the fiscal first quarter of 2027, is expected on Dec. 23. Analysts expect revenue of $61.5 billion, up 351% from $13.64 billion a year earlier, and earnings of $38.11 per share. Image: Shutterstock
