NVIDIA and OpenAI announced a letter of intent on September 22, 2025, covering at least 10GW of NVIDIA systems for OpenAI’s next-generation AI infrastructure. NVIDIA intends to invest up to $100 billion in OpenAI in stages as gigawatts are deployed. The first gigawatt is targeted for the second half of 2026 using NVIDIA’s Vera Rubin platform; the broader rollout and final terms remain conditional.

What the NVIDIA–OpenAI announcement says

A letter of intent, not a completed contract

The companies described the arrangement as a letter of intent. It sets out the intended scale and structure, but it is not the same as a final contract committing both parties to every phase. The announcement does not specify final sites, detailed contracts, financing terms, or a delivery schedule for all 10GW.

Investment staged around deployment

NVIDIA intends to invest up to $100 billion in OpenAI progressively, tied to deployment of each gigawatt. “Up to” is a ceiling, not a statement that the full amount has already been invested or will necessarily be invested. The announcement does not give a per-gigawatt investment amount or specify the detailed conditions for each tranche.

What 10GW of AI infrastructure means

A gigawatt is a measure of power capacity, not a count of GPUs or a measure of energy consumed over time. The announced 10GW describes the scale of the planned NVIDIA systems; the companies also characterize that scale as millions of GPUs. It does not, by itself, say how many facilities will be built, where they will be located, or how much power they will use in any particular year.

OpenAI says the infrastructure is intended to train and run its next-generation models and support inference at scale. Inference is the computing used to generate responses when people or applications use a model, as distinct from the computing used to train it.

When the first systems are expected

The first 1GW is targeted for the second half of 2026 on NVIDIA’s Vera Rubin platform. That is a target in the announcement, not confirmation that the capacity has been delivered. The public announcement does not provide dates for later gigawatts or establish when the full planned capacity would be online.

How the investment differs from the infrastructure cost

NVIDIA’s 2025 investor presentation estimates that each 1GW build-out requires approximately $50–60 billion in total spend. That is a broader project-cost estimate, not the amount NVIDIA says it will invest in OpenAI for each gigawatt.

Figure What it refers to What it does not establish
Up to $100 billion NVIDIA’s intended staged investment in OpenAI, associated with gigawatt deployments, as described in the September 22, 2025 announcement. The amount is not stated as a completed investment, guaranteed total, or fixed payment for each gigawatt.
Approximately $50–60 billion per 1GW build-out NVIDIA’s 2025 investor-presentation estimate of total spend for a 1GW build-out. It is not identified as NVIDIA’s equity contribution or as a detailed breakdown of who pays for each component.

The two figures describe different things: one is an intended investment in OpenAI, while the other is an estimate of total infrastructure spend. They should not be treated as interchangeable amounts.

Does the plan amount to circular financing?

The announcement links NVIDIA’s investment to the rollout of NVIDIA systems, so there is a clear commercial connection between the investment and the hardware deployment. But the announcement does not detail how the investment proceeds would be used, how system purchases would be financed, or how ownership and payments would be structured. On the public terms alone, it is not possible to determine whether funds would flow back to NVIDIA through system purchases or to characterize the arrangement as circular financing.
