On August 28, NVIDIA (NVDA.O) saw its market capitalization surge by $442 billion on Thursday, marking the second-highest single-day gain for an individual stock in history. By the close of U.S. stocks on Thursday, NVIDIA's share price soared by 8.7%, representing its largest increase since April 2025. This market cap growth trails only Microsoft's $450 billion single-day gain less than a month ago. The surge in share price on Thursday was driven by NVIDIA's robust earnings guidance, which dispelled investor concerns about a potential slowdown in AI growth momentum, underscoring the continued strength of AI expansion. Institutional analysis pointed out that NVIDIA's earnings guidance indicates a potential upside of over $100 billion beyond current market expectations. JPMorgan believes that while NVIDIA's outlook far exceeded expectations, it may still be conservative, as the company explicitly stated that its current forecast is constrained by supply limitations, suggesting that demand growth could be even higher if supply were unrestricted.
