Shares of technology companies rose ahead of AI chipmaker Nvidia's earnings report.
Microsoft said it's hiring Sam Altman to helm a new advanced artificial-intelligence research team, after his bid to return to OpenAI fell apart Sunday with the board that fired him declining to agree to the proposed terms of his reinstatement.
The confusion over Altman's potential return to OpenAI could lead many of the firm's programmers to follow him to Microsoft, analysts said.
Meanwhile, Amazon.com launched a program to train millions of workers in artificial-intelligence skills as the tech giant seeks to gain an edge in a pitched battle for talent with Microsoft, Google and other companies.
"As if Nividia's earnings weren't already interesting enough for a slow, shortened holiday week, musical chairs within some of the top AI players make this space quite exciting," said J.D. Joyce, president of financial advisory Joyce Wealth Management.
