Nvidia Corporation (NVDA) has reached a new all-time high closing price of $182.70, resulting in a market capitalization of approximately $4.455 trillion as of August 2025. This milestone positions Nvidia as one of the largest companies in the S&P 500, with a market cap nearly comparable to the entire Health Care sector following recent declines in UnitedHealth Group and Eli Lilly. Nvidia's stock performance has been extraordinary over recent years, posting gains of 238% in 2023, 171.2% in 2024, and 60% year-to-date in 2025. Over the past decade, Nvidia has been the best-performing S&P 500 stock in both 2023 and 2024. This growth has outpaced major indices and ETFs such as QQQ, which returned approximately 2.1 times in the same period, while Nvidia's portfolio performance yielded roughly 18 times returns since 2023. The company’s rise is closely linked to advancements and demand in artificial intelligence (AI) technology, which investors consider a transformative opportunity rather than a speculative bubble. Nvidia joined the ranks of trillion-dollar companies in 2023, alongside other tech giants like Apple, Amazon, Microsoft, and Alphabet. Analysts and market commentators continue to update valuation metrics and discuss Nvidia's potential for further expansion amid ongoing AI developments. Despite some skepticism about the proximity of artificial general intelligence (AGI), the consensus among many investors is that AI represents a durable growth driver for Nvidia and the broader technology sector.
