Santiago/Getty ImagesInvestor concerns about debt levels associated with the AI build-out are weighing on the shares of several companies in the sector and pushing bond yields related to those infrastructure projects to distressed levels. CoreWeave Inc. CRWV-Q, a specialized “neocloud” AI compute provider, is one of two anchor tenants for Bell Canada parent BCE Inc.’s BCE-T planned AI data centre in Saskatchewan. The company’s shares have been among the most affected this week, as investors signal unease about extensive AI-related development financed with debt. CoreWeave’s stock dropped by 15 per cent on the Nasdaq exchange on Wednesday before bouncing back up by nearly 6 per cent on Thursday, buoyed in the afternoon when the chief executive officer of Nvidia Corp. NVDA-Q, Jensen Huang, publicly signalled his support for the company. The chip giant has invested billions of dollars into AI and neocloud companies, including CoreWeave.
