As chatbots boom, Nvidia sales outlook beats Wall Street expectations

Chip designer Nvidia Corp forecast first-quarter revenue above Wall Street estimates on Wednesday as the company benefits from a boom in spending to power chatbots and other artificial intelligence technologies.

The sales outlook sent Nvidia’s shares up 8% in extended trading. Nvidia, the world’s largest supplier of chips used in data centers for training AI, has become a key hardware supplier for large tech companies such as Microsoft Corp that are building services like chat-powered search engines.
