Nvidia shares' 9% recovery Tuesday was the second-best day in terms of market cap added for any company ever—but the company faced another selloff Wednesday.

Chip stocks in the U.S. and Europe rose on Wednesday for a second straight day, recovering from a punishing selloff triggered by China's low-cost DeepSeek artificial intelligence tool at the start of the week.

A new Chinese AI model threatens to diminish the need for Nvidia’s most-expensive chips, but some say the concerns are overblown.

China’s DeepSeek says it trained an AI model for less than $6 million. This is as big U.S. tech companies have poured billions of dollars into AI chips and systems for their projects.
