USD.AI Bridges DeFi and AI by Turning Stablecoins Into Loans for Nvidia GPUs

The USD.AI protocol aims to connect the surplus liquidity in Decentralized Finance (DeFi), often held in stablecoins earning low yields, with the capital demands of the Artificial Intelligence (AI) industry for expanding data centers and acquiring Nvidia GPUs. The protocol, which has about $345 million in circulation, backs its synthetic dollar with short-term credit secured by tokenized Nvidia GPUs housed in insured data centers. These GPUs generate revenue by selling compute time for AI model training and inference, with the resulting cash flow servicing the debt. The system relies on three mechanisms: CALIBER, which legally bridges the physical GPU to an on-chain NFT collateral; the FiLo Curator, which handles underwriting and absorbs initial defaults; and QEV (queue extractable value), which manages liquidity by queuing redemption requests, allowing patient lenders to earn yield from borrower repayments rather than token emissions. Current staked sUSDai yields range from 13% to 17%, and USD.AI is positioned as a prototype for a broader "InfraFi" (decentralized infrastructure finance) model.
