CoreWeave (CRWV) debuted today on the Nasdaq, backed by a stake from Nvidia (NVDA). Co-founder Brannin McBee calls his company "THE A.I. hyperscaler" serving as a leader in the space and a pure play in the markets. Despite DeepSeek rattling markets over the future of A.I. spend, Brannin says CoreWeave has experienced the inverse after seeing "relentless" client demand.
