U.S. stocks fell, while oil prices climbed.

The S&P 500 slipped 0.3% Thursday, its first loss in four days. The Dow Jones Industrial Average dropped 0.5%, and the Nasdaq composite lost 0.3%.

The company behind Booking.com and Priceline sank to one of the market’s sharper losses as worries continue about whether AI competitors could steal away its customers. Such concerns have been rolling through Wall Street recently and hitting various industries.

Private-credit companies that lend to businesses seen as possible victims from AI also fell sharply.

Oil prices rose with worries about a potential U.S.-Iran conflict.
