Nvidia stock rose 3.6% on Monday along with the broader market. More earnings reports are set to provide the direction of artificial-intelligence stocks this week.

Among other chip makers, Advanced Micro Devices rose 3% and Broadcom gained 3.2% on Monday.

With earnings from the major U.S. technology companies largely out of the way, Nvidia stock could lack much of a catalyst until its own report on Aug. 27. However, quarterly results from its smaller peer Advanced Micro Devices and server maker Super Micro Computer on Tuesday will provide some insight into demand for AI processors.

In the meantime, Nvidia looks to be putting some of its profits to use. Nvidia is in talks to invest in AI infrastructure provider Vast Data in a funding round that could give the start-up a valuation as high as $30 billion, according to a Reuters report on Saturday, citing anonymous sources.

Vast Data specializes in storage technology for AI data centers, enabling data to move between processors. Nvidia declined to comment on the report.
