The S&P 500 index closed above 5000 for the first time on Friday, and Nasdaq briefly traded above 16,000, thanks to growth from large corporations and chip manufacturers, including Nvidia, as investors focused on artificial intelligence technologies and expected high profits.

This followed a Wall Street Journal report that OpenAI CEO Sam Altman was negotiating with investors to fund a technology initiative aimed, among other things, at increasing chip production for powerful artificial intelligence.
"So far, the AI story has been about building infrastructure, chips, and data centers," said David Lefkowitz, head of US equities at UBS Global Wealth Management, adding that it "highlights potentially huge demand for AI infrastructure in the future."
