Nvidia Nears $6 Trillion Market Value After 20% Weekly Surge

Shares of Nvidia climbed again on Thursday, extending a powerful rally that pushed the chipmaker’s stock up nearly 20% over the past week amid relentless investor enthusiasm surrounding artificial intelligence spending.

The stock rose as much as 4.7% to $236.47 during trading, adding more than $900 billion to Nvidia’s market capitalization and bringing the company close to the unprecedented $6 trillion valuation mark, a level never before reached by any publicly traded company.

The latest surge underscores the intensity of investor demand for companies seen as major beneficiaries of the global AI boom, with semiconductor firms remaining at the center of the rally.

Nvidia also drew additional attention this week after Chief Executive Officer Jensen Huang joined U.S. President Donald Trump during his visit to China in what reports described as a last-minute addition to the trip.

The broader semiconductor sector has posted sharp gains in recent months. The PHLX Semiconductor Sector Index has surged nearly 70% since the end of March, while major chipmakers including Intel, Micron Technology, Advanced Micro Devices, and Broadcom have also recorded significant advances.

The scale of the rally has fueled growing concerns among some analysts and investors that equity markets may be entering an AI-driven bubble vulnerable to a sharp correction. According to data compiled by Bloomberg, Nvidia and Micron alone have accounted for more than 30% of the gains in the S&P 500 this year.

Thursday also saw a major public market debut for Cerebras Systems, one of the leading artificial intelligence chip startups. The company’s initial public offering, the largest of the year so far,  attracted heavy investor demand, with shares surging as much as 109% after trading began.

The rapid rise in AI-related stocks continues to reflect Wall Street’s expectation that spending on data centers, advanced chips, and AI infrastructure will remain elevated as companies race to expand their artificial intelligence capabilities.
