OpenAI has announced a $110 billion funding round backed by Amazon, Nvidia, and SoftBank — one of the largest private financings in history. The round more than doubles the company’s previous $40 billion raise, which had itself been the largest private technology deal on record, underscoring how quickly capital is flowing into frontier AI development.
Who invested, and at what valuation
According to OpenAI, Amazon contributed $50 billion, Nvidia $30 billion, and SoftBank $30 billion. The investment lifts OpenAI’s pre-money valuation to roughly $730 billion — a sharp increase from the $500 billion mark set in a secondary financing in October — and to about $840 billion once the new capital is included. The company indicated that additional investors are expected to join as the round progresses.
OpenAI said the funding would support its pursuit of artificial general intelligence (AGI) — broadly, AI that matches human-level capability across tasks — as well as wider deployment of its existing products.
Deeper ties with Amazon and Nvidia
Alongside the investment, Amazon announced a multiyear strategic partnership with OpenAI, including work on customized models to help power Amazon’s customer-facing applications. OpenAI also said it would expand its long-standing collaboration with Nvidia, committing to 3 gigawatts of dedicated inference capacity and 2 gigawatts of training capacity on Nvidia’s forthcoming Vera Rubin systems.
Notably, OpenAI emphasised that these arrangements do not change its existing relationship with Microsoft. Microsoft Azure remains the exclusive cloud provider for OpenAI’s API, so the Amazon partnership sits alongside — rather than replaces — that agreement.
Limitations and what to watch
Private-market valuations are not the same as public-market prices: an $840 billion figure reflects what a small set of strategic investors agreed to pay, not a liquid market value, and such marks can move quickly. Capacity commitments measured in gigawatts depend on data-centre build-outs, power availability, and hardware delivery timelines that often slip. Much of the rationale rests on continued progress toward AGI, a goal with no agreed definition or timeline. The durable facts are the named investors, the headline amount, and the structure of the cloud and compute relationships; the longer-term return on that capital remains unproven.
