USDai's CALIBER protocol, focused on on-chain GPU financing, is projected to reach a $300 million valuation shortly after its launch. The protocol has entered a contract with Polymarket to bet on whether USD.AI's fully diluted valuation will exceed this figure, with current trading indicating a 94.2% probability of success. This marks a significant increase from 36% a week ago, reflecting growing confidence in the demand for on-chain AI funding. The market activity around USD AI's valuation is driven by the innovative model of using tokenized NVIDIA GPUs as collateral on the Base blockchain. Similar bullish sentiment is observed in related markets, such as Predict.fun, which shows a 58% probability of approval. Despite USDC's daily trading volume exceeding $20,000, the market remains susceptible to volatility, as evidenced by a recent price spike. The focus remains on whether on-chain GPU financing can attract enough funding and usage to sustain such a valuation.
