Nvidia made history Wednesday when its stock briefly lifted the company’s market cap above $4 trillion, making it the first public company to reach that milestone. Although the chipmaker closed the day slightly below that figure at $3.97 trillion, the achievement marked another major step in Nvidia’s rise as the dominant supplier of artificial intelligence hardware worldwide.

The California-based company, founded in 1993, has spent more than three decades building up its reputation. It first became widely known among gamers for its high-performance graphics processing units. But it wasn’t until the AI boom took off that Nvidia moved into global focus. The launch of ChatGPT in late 2022 and the race to scale generative AI models created explosive demand for chips that could process massive datasets at high speed. Nvidia met that demand first.

How Nvidia Briefly Became the First Member of the $4 Trillion Club

Nvidia reached a $1 trillion market cap in May 2023, hit $2 trillion by February 2024, and crossed $3 trillion in June 2025. That upward trajectory reflects not just bullish sentiment, but a structural advantage. The company’s GPUs are used by major players like Microsoft, Google, and Amazon to train and run their AI models. Nvidia’s latest Blackwell Ultra chip, announced in March, supports AI applications with more advanced reasoning capabilities.

The company reported $44.1 billion in revenue last quarter, up 69% from the same period last year. Nvidia’s stock is up 22% year-to-date and more than 74% since early April, following a steep correction earlier this year. Between January and April, shares fell 37% on fears that China’s DeepSeek model might reduce demand for high-end chips. Those concerns proved premature.

Nvidia’s climb has not been without geopolitical headwinds. Export restrictions on its H20 chips cost the company $8 billion in lost sales to China. CEO Jensen Huang said during a May earnings call that the China market—valued at $50 billion—is effectively closed to U.S. chipmakers. Despite that, Nvidia’s position remains strong due to unmatched supply, customer dependency, and high switching costs in AI infrastructure.

Nvidia’s AI Dominance Comes With Investor Caution

Nvidia’s rapid rise raises a key investor question: Is it too late to buy Nvidia stock? Some analysts say no. The company’s lead in AI hardware is still widening, not shrinking. Loop Capital forecasts that Nvidia could reach a $6 trillion valuation by 2028, citing its near-monopoly position in chips critical to generative AI. With global AI infrastructure spending expected to surpass $200 billion by 2028, Nvidia remains central to that buildout.

Still, buying at or near the peak carries risk. Nvidia’s valuation already reflects high expectations. Any regulatory, competitive, or supply-related missteps could reset those numbers quickly. Some investors remember January’s sell-off when DeepSeek spooked markets with a cheaper AI alternative. Others worry that Washington–Beijing tensions could limit future growth or trigger regulatory clampdowns on AI exports.

For long-term investors, Nvidia may still offer value. Its role in Project Stargate, the $500 billion AI infrastructure initiative championed by President Trump, signals deep integration into national tech planning. Its customer base includes every major cloud provider, and new product rollouts continue at a fast pace. CEO Jensen Huang’s visibility is also rising. Now one of the ten richest people globally, he remains actively involved in product strategy and international partnerships. Short-term traders should be more cautious. Valuation gaps and profit-taking can create sharp price swings. But for institutional investors with a long view, Nvidia still represents a core play on the AI economy.
