Nvidia and Broadcom claw back some losses from Monday’s deep selloff in artificial-intelligence stocks, while General Motors posts better-than-expected adjusted earnings.

Nvidia is the gold standard and leading provider of the graphics processing units (GPUs) used to train and run AI systems. The company is believed to control as much as 98% of the data center GPU market, according to semiconductor analyst firm TechInsights. If AI models can be trained on lower-cost, inferior chips, Nvidia has a lot to lose.
