Nvidia heads for record close as AI chipmaker's market cap tops $3.4 trillion

Nvidia shares headed for a record close on Monday as Wall Street gears up for earnings season and updates from all of the chipmaker's top customers on their planned spending on artificial intelligence infrastructure.

The stock climbed 2.6% to $138.31 as of about 1 p.m. Eastern time. Its highest close to date was $135.58 on June 18. The shares are now up almost 180% for the year and have soared more than nine-fold since the beginning of 2023.

Nvidia, widely viewed as the company selling the picks and shovels for the AI gold rush, has been the biggest beneficiary of the generative AI boom, which started with the public release of OpenAI's ChatGPT in November 2022. Nvidia's graphics processing units (GPUs) are used to create and deploy advanced AI models that power ChatGPT and similar applications.

Companies including Microsoft, Meta, Google, and Amazon are purchasing Nvidia GPUs in large quantities to build increasingly large clusters of computers for their advanced AI work. Those companies are all slated to report quarterly results by the end of October.

Of the billions of dollars the top tech companies are spending annually on their AI buildouts, an outsized amount is going to Nvidia, which controls about 95% of the market for AI training and inference chips, according to analysts at Mizuho.

Nvidia's revenue has more than doubled in each of the past five quarters, and at least tripled in three of those periods. Growth is expected to modestly slow the rest of the year, with analysts projecting expansion of about 82% to $32.9 billion in the quarter ending in October, according to LSEG.

Nvidia recently said that demand for its next-generation AI GPU called Blackwell is "insane" and it expects billions of dollars in revenue
