Nvidia, Meta Platforms, Broadcom and other technology companies have provided as much as $300 billion in guarantees supporting AI data centers and chips over the past year, leaving much of the potential exposure outside conventional debt. The structures typically guarantee a minimum future value for data centers or computing equipment owned by special-purpose entities, making projects easier and cheaper to finance, but the technology company can become responsible for part of the shortfall if those assets fetch less than the guaranteed amount. Nvidia has agreed to provide as much as $105 billion of support for SB Energy's Ohio data-center campus serving OpenAI, while also backing as much as 25% of certain other financing packages using Nvidia hardware. Broadcom has maximum exposure of about $29 billion from backing AI-rack leases connected to Anthropic. Meta supplied a $28 billion guarantee supporting its Hyperion data-center venture with Blue Owl, helping the project raise $27 billion while keeping most of the obligation outside Meta's reported balance sheet. Morgan Stanley estimates seven major cloud and chip companies have accumulated more than $3.1 trillion in off-balance-sheet commitments and other credit support. The risk appears if computing capacity becomes oversupplied, customers struggle financially or rapidly improving chips cause older hardware to depreciate faster than expected.
