C3.ai (NYSE:AI) shares surged by more than 21% Friday as investors poured into the artificial intelligence stock on the last day of the first quarter of the year.
More than 61M shares of C3.ai (AI) had been exchanged by the time U.S. stock markets closed--more than three times the 19.2M shares that trade hands on an average day.

However, there wasn't much in the way of direct news involving C3.ai (AI). The company, like many in the AI space, has become one of the hottest on Wall Street of late since Microsoft (MSFT) announced a multi-year, multi-billion-dollar partnership with ChatGPT developer OpenAI.
Earlier on Friday, Italy enacted a temporary ban on ChatGPT in the country for at least 20 days over concerns over how the technology justifies its methods of data collection of individuals.
