Nvidia briefly hits $4 trillion market value, cementing AI leadership

Nvidia (NVDA.O) briefly reached a market capitalization of $4 trillion on Wednesday, becoming the first company ever to hit this milestone and reaffirming its dominance in the artificial intelligence (AI) sector. Shares surged as much as 2.8% to an all-time high of $164.42 before closing up 1.8%, giving Nvidia a market value of approximately $3.97 trillion.

This milestone reflects Wall Street’s strong confidence in Nvidia’s leading role in powering AI innovation, with its high-performance chips crucial to advancements in the technology. Robert Pavlik, senior portfolio manager at Dakota Wealth, remarked that the rally “highlights the fact that companies are shifting their asset spend in the direction of AI,” which he sees as the future of technology.

Nvidia’s stock has seen a remarkable recovery after a slow start in 2025, which was rattled by competition from Chinese AI models like DeepSeek. The company reached a $1 trillion valuation in June 2023 and has since nearly quadrupled in value within about a year—outpacing other tech giants like Apple and Microsoft, the only other U.S. firms with market caps above $3 trillion.

Microsoft, the second most valuable U.S. company, closed Wednesday at $503.51 per share with a $3.74 trillion market cap. Nvidia’s rally has lifted it by approximately 74% from its April lows, coinciding with renewed optimism about U.S. trade relations.

Currently, Nvidia represents 7.3% of the S&P 500 index, slightly more than Apple’s 7% and Microsoft’s 6%. Its valuation now surpasses the combined stock market value of Canada and Mexico, as well as all publicly listed companies in the UK.

Despite its high valuation, Nvidia’s 12-month forward price-to-earnings ratio stands at 32, below its three-year average of 37.

While Nvidia’s GPUs dominate AI workloads, rivals such as Advanced Micro Devices (AMD) and others are seeking to chip away at its market share by offering more affordable alternatives. Meanwhile, major customers like Amazon, Microsoft, and Alphabet face investor pressure to moderate their AI spending.

Nvidia posted $44.1 billion in revenue for the first quarter of 2025, a 69% increase year-on-year. For the second quarter, the company projects revenue around $45 billion, plus or minus 2%, with earnings due on August 27.

Year-to-date, Nvidia’s stock is up about 22%, outperforming the Philadelphia Semiconductor Index’s roughly 15% gain.
