CoreWeave (CRWV) is pushing back on fears of overbuilt AI infrastructure and a bubble in the sector.

"Not that we see," CoreWeave co-founder Brannin McBee told Yahoo Finance today about whether customers are getting worried about the pace of investment in artificial intelligence. "And this discussion of an AI bubble — we don't understand it."

CoreWeave priced its initial public offering (IPO) at $40 a share Thursday night. The cloud play initially expected to sell shares in the range of $47 to $55, but concerns about the pace of AI spending and CoreWeave's business model caused it to downsize the offering.
