Nvidia becomes first company to reach $5 trillion valuation amid AI boom

Nvidia crossed into uncharted territory on Wednesday, becoming the first publicly traded company to reach a $5 trillion market valuation. The artificial intelligence chipmaker's stock opened up more than 3% that day, marking yet another milestone in a climb that has reshaped the entire technology sector and raised questions about whether the enthusiasm has outpaced reality.

The scale of Nvidia's value is difficult to grasp in conventional terms. The company is now worth more than the gross domestic product of every nation on earth except the United States and China. Just three months earlier, in July, Nvidia had crossed $4 trillion. Two years and three months before that, it was worth $1 trillion. The acceleration has been extraordinary: the stock has gained more than 50% in 2025 alone, and over 1,500% across the past five years. By comparison, the S&P 500 has risen 17% this year, and the Nasdaq 23%. Nvidia's market capitalization now exceeds the combined value of every major chip competitor—AMD, Intel, Broadcom, TSMC, Micron, ASML, Lam Research, Qualcomm, and Arm Holdings.

The company's ascent has become the defining symbol of an artificial intelligence investment frenzy that has pushed U.S. stock markets to record levels throughout the year. The wealth created has been concentrated: major shareholders in the AI industry have become billionaires on the strength of these gains. Yet the velocity of the rise has triggered warnings from economists who see echoes of the internet bubble of the late 1990s—a period when valuations soared on speculation and enthusiasm before collapsing.

CEO Jensen Huang addressed these concerns directly on Tuesday, the day before Nvidia hit $5 trillion. Asked whether the AI sector might be in a bubble, Huang told NBC News that the companies driving the boom are generating genuine revenue and selling profitable products. That same day, Huang had held Nvidia's annual artificial intelligence conference in Washington, D.C., where he announced a series of partnerships and investments with companies spanning from Nokia, the 5G network supplier, to Uber, the ride-sharing platform. He also projected $500 billion in AI chip orders through the following year.

The timing of Nvidia's milestone was amplified by geopolitical signals. On Tuesday evening, President Donald Trump told reporters he would be discussing Nvidia's Blackwell chip with Chinese President Xi Jinping during a meeting scheduled for Thursday in South Korea. Blackwell is Nvidia's most powerful AI processor. Trump has called it "super duper," but the U.S. government has restricted its sale to China, citing national security concerns that Beijing could gain a technological advantage over the United States with access to such advanced hardware.

The administration's stance on these restrictions has been inconsistent. Commerce Secretary Howard Lutnick said in July on CNBC that the U.S. would not sell China its best AI technology, nor its second or third best. But America's "fourth best" AI technology, Lutnick suggested, was acceptable to export. That ambiguity—about what constitutes a threat and what constitutes acceptable commerce—hangs over Nvidia's continued growth. The company's valuation rests partly on the assumption of continued sales to global markets, including China. Any tightening of export controls could reshape that calculus. For now, Nvidia stands alone at $5 trillion, a monument to the market's belief in artificial intelligence, and a test of whether that belief can be sustained.
