Nvidia was set to open above a $5 trillion market value on Wednesday, becoming the first company to reach the milestone after a powerful rally that has made the chip designer the centerpiece of the artificial intelligence boom.

The Santa Clara chipmaker is now worth more than the stock markets of Netherlands, Spain, UAE, Italy and Poland combined, making it increasingly influential. With a 50% gain in 2025 alone, Nvidia now accounts for 9% of the S&P 500, raising questions about market concentration and valuation sustainability.

Nvidia reaches a $5 trillion market value, driven by AI demand and robust stock market performance, outstripping major economies' GDPs and making significant industry investments.

The topic of the "best" artificial intelligence (AI) stock to buy right now is a spirited debate. One may advocate for companies building AI software, while another may be a proponent of rising stars like AMD (NASDAQ: AMD) and Broadcom (NASDAQ: AVGO) after their OpenAI partnership announcement.

The tech giant owes much of its $4.89 trillion market capitalization to the use of its systems to train AI models. Now it’s pushing deeper into the realm of corporations that will employ such models to solve real-life problems.

Nvidia’s latest rally comes as Donald Trump said he expects to speak with China’s Xi Jinping about the company’s flagship Blackwell artificial intelligence chip.

Nvidia is working with several communications companies, including Booz Allen, Cisco, MITRE, ODC and T-Mobile to create what they're calling America's first AI-native wireless stack for 6G, integrating advanced AI across hardware, software and architecture to prepare future networks for the growth of AI traffic.

At its GTC DC event, the company announced major initiatives spanning quantum computing, 6G networks and “AI factories” built with the United States Department of Energy and Oracle Corp. — all framed as part of what executives described as America’s next industrial and scientific renaissance.
