OpenAI announced a $110 billion funding round on February 27, with Amazon investing $50 billion, Nvidia $30 billion and SoftBank $30 billion, CNBC reported. Amazon also announced a multiyear strategic partnership with OpenAI. Crunchbase called it the largest venture deal ever.
Later reporting put the round at $122 billion at an $852 billion valuation as of March. Many of the investors are also OpenAI's suppliers and cloud partners, which is why analysts describe much of the AI economy as a closed loop of capital and compute.
