Nvidia is using its powerful balance sheet to help more companies buy its expensive AI chips, and possibly make some money back too.

It’s promising to financially backstop young cloud providers that rent out its graphics processing units in exchange for a share of their revenues. The backstop would come in the form of promising to rent back unused GPUs if the companies can’t find AI developers to rent them, according to GPU cloud providers Firmus and Sharon AI, which are participants in the new program, and three executives at other firms that do business with Nvidia.
