According to an August 9 assessment by ChatGPT, Nvidia (NASDAQ: NVDA) is the better stock to buy in 2026 compared with Micron Technology (NASDAQ: MU), though Micron could deliver greater upside if demand for high-bandwidth memory (HBM) remains exceptionally strong. ChatGPT based its preference for Nvidia on its stronger competitive moat, greater earnings visibility, and broader position across the AI infrastructure market. Nvidia generated a record $68.1 billion in quarterly revenue in fiscal Q4 2026, up 73% from a year earlier, with Data Center revenue reaching $62.3 billion, an increase of 75%. For the full fiscal year, Nvidia generated $215.9 billion in revenue, up 65% year over year. The company will report its fiscal Q2 2027 results on August 26, 2026. Elevated expectations remain a key risk, as Nvidia must maintain exceptional growth to justify its valuation. Micron reported $41.46 billion in fiscal Q3 2026 revenue, compared with $23.86 billion in the previous quarter and $9.30 billion a year earlier. GAAP net income reached $28.24 billion, while operating cash flow climbed to $25.39 billion. Micron’s data-center business generated $13.77 billion from Cloud Memory and $11.52 billion from Core Data Center, with gross margins of 83% and 87%, respectively.
