As of 12:59 p.m. ET, the stock was up 21.9%. Last night, DA Davidson analyst Gil Luria raised his rating on the AI-focused software-as-a-service (SaaS) stock to "buy," saying C3.ai is "a truly scarce asset in a critical software arena," and that the generative AI could be a "killer app" for artificial intelligence. The analyst endorsement was the latest piece of good news for C3.ai, whose shares have surged this week as investors look for ways to get exposure to the artificial intelligence boom.
