Six major finance firms, including BlackRock Inc and Goldman Sachs Group Inc, are helping Nvidia Corp ease investor anxiety over its commitments to fund the AI boom, after CEO Jensen Huang announced Monday the coalition is lining up more than US$500 billion for the AI build-out. The group will independently judge deals, with Nvidia’s contribution relatively limited. This outside money and Wall Street approval aim to alleviate worries that Nvidia was inflating an AI asset bubble with circular financing. In less than three weeks, a gauge of Nvidia’s credit risk had nearly doubled over concerns that customer loans could cause future pain. On Tuesday, the cost of protecting Nvidia’s debt against default dropped and bonds rallied, with risk premiums over US Treasuries falling to last week’s levels. GW&K Investment Management LLC portfolio manager Brett Kozlowski called the commitment “a positive development.” Nvidia is a key player in the US$5.5 trillion global AI race, and its market valuation tops US$5.2 trillion. Late last month, Bloomberg reported Nvidia was in talks to backstop as much as US$250 billion to help OpenAI lease computing power from an Ohio data center hub, and was also discussing financing US$350 billion of OpenAI’s chip purchases.
