OpenAI and NVIDIA did not announce a completed $100 billion payment. On September 22, 2025, they announced a letter of intent for at least 10 gigawatts of NVIDIA systems, with NVIDIA intending to invest up to $100 billion progressively as capacity was deployed. In February 2026, OpenAI described a $30 billion NVIDIA investment in a broader $110 billion funding round and a 5-gigawatt Vera Rubin plan. Those are distinct public descriptions; the available announcements do not establish that the full $100 billion was invested or how the later $30 billion maps legally onto the earlier proposal.

What the September 2025 announcement actually said

OpenAI and NVIDIA announced their arrangement on September 22, 2025, describing it as a letter of intent. It called for at least 10 gigawatts of NVIDIA systems to support OpenAI’s next-generation AI infrastructure. NVIDIA said it intended to invest up to $100 billion in OpenAI progressively as each gigawatt was deployed.

The first gigawatt was targeted for the second half of 2026, using NVIDIA’s Vera Rubin platform. OpenAI said the infrastructure would support both training and running future models. The announcement described those efforts as being “on the path to deploying superintelligence”; it did not say that superintelligence had been achieved or give a date for it.

What “up to $100 billion” means

The figure was a proposed maximum tied to deployment, not a statement that NVIDIA transferred $100 billion at announcement or committed to a single immediate payment. The stated mechanism linked investment progressively to each gigawatt deployed. The announcement did not disclose a complete final legal agreement, payment schedule, or terms sufficient to treat the ceiling as money already invested.

The plan also involved more than buying standalone chips. It paired NVIDIA systems with the data-center and power capacity needed to operate them. In practical terms, it combined a proposed equity investment in OpenAI with a large infrastructure deployment in which NVIDIA would supply systems and related technology. That creates financial interdependence: NVIDIA could help fund a customer that may then spend on NVIDIA infrastructure. This is a reasonable issue for investors to examine, but the announcement alone does not establish that the arrangement is improper or prove exactly how invested funds would be spent.

What changed in February 2026

On February 27, 2026, OpenAI announced a broader $110 billion funding round at a $730 billion pre-money valuation. OpenAI identified $30 billion from NVIDIA, $30 billion from SoftBank, and $50 billion from Amazon. It also described an expanded NVIDIA infrastructure relationship involving Vera Rubin systems: 3 gigawatts of dedicated inference capacity and 2 gigawatts of training capacity. The figures and round are set out in OpenAI’s February update.

The $30 billion is the NVIDIA investment OpenAI publicly identified in that round. The first-party announcements do not say whether it is separate from, or legally part of, the earlier proposed investment ceiling. It should not be added to the original $100 billion as if the two were necessarily cumulative. Nor does the February description of 5 gigawatts establish that the earlier 10-gigawatt plan was cancelled or reduced; the announcements describe different stages or scopes, without resolving their full relationship.

What 10 gigawatts means—and what it does not

A gigawatt measures power capacity, not a count of GPUs or a level of AI capability. The September announcement described a planned infrastructure scale that it said would represent millions of GPUs, but did not give a final accelerator count, site-by-site schedule, total electricity consumption, or completed construction timetable.

  • Power capacity is the electrical load infrastructure is designed to support.
  • Compute capacity depends on processors, memory, networking, and software working together.
  • Utilization is how much of that capacity is operating at a given time.
  • Training uses compute to develop or improve models; inference runs models to answer users or applications.

Consequently, a planned 10-GW buildout does not mean 10 GW was operating when the companies announced it. The February split between 3 GW for inference and 2 GW for training is useful because it distinguishes serving workloads from model development; it does not establish how much capacity was operational.

Why OpenAI wants more compute

OpenAI’s stated rationale is growing demand across consumers, developers, and businesses, which requires computing capacity, distribution, and capital. More infrastructure can support model training and the day-to-day operation of services, including reasoning, multimodal, and agentic workloads. Inference capacity also matters when many people or applications need responses with low latency, while geographically distributed capacity can help serve demand across regions.

More GPUs alone do not guarantee better models or products. Results also depend on data, algorithms, research, networking, power, cooling, software, and whether the systems can be deployed and kept busy enough to justify their cost.

Why NVIDIA would invest in a major customer

The arrangement could align NVIDIA’s financial interest with a large, long-term customer. NVIDIA may benefit from demand for its computing systems, networking, and broader data-center infrastructure, while an equity investment could give it financial exposure to OpenAI’s growth. The linkage may also help coordinate capital and deployment at a scale that would be difficult to arrange through equipment sales alone.

That alignment has trade-offs. OpenAI could gain access to capacity and capital, but a close relationship with one dominant accelerator supplier could constrain flexibility if competing chips or cloud services become more attractive. For NVIDIA, the investment and prospective equipment demand are linked: expected growth in AI infrastructure does not eliminate execution risk, including construction, power availability, or demand that falls short of plans.

How this differs from Stargate and other OpenAI infrastructure plans

The NVIDIA announcement is not the same as Stargate. OpenAI announced Stargate on January 21, 2025, as a separate U.S. AI infrastructure initiative intended to invest $500 billion over four years, with an initial $100 billion deployment. Its initially named equity funders were SoftBank, OpenAI, Oracle, and MGX. The Stargate announcement and NVIDIA’s later letter of intent have different participants and structures, even though both concern infrastructure at very large scale.

Announcement Announced scale What it describes
OpenAI–NVIDIA, September 2025 At least 10 GW of planned NVIDIA systems; up to $100 billion in proposed NVIDIA investment A letter of intent linking infrastructure deployment with progressive investment
Stargate, January 2025 $500 billion intended over four years, with $100 billion initially A separate AI infrastructure initiative; initial equity funders named were SoftBank, OpenAI, Oracle, and MGX
OpenAI funding round, February 2026 $110 billion total, including $30 billion from NVIDIA A broader funding round and an NVIDIA capacity description of 3 GW for inference and 2 GW for training

OpenAI has also described a broader infrastructure strategy involving Microsoft, Oracle, AWS, CoreWeave, Google Cloud, NVIDIA, AMD, AWS Trainium, Cerebras, and its own chip efforts with Broadcom, as well as data-center relationships involving Oracle, SBE, and SoftBank. NVIDIA is a major part of that ecosystem, not the entirety of OpenAI’s compute strategy. See OpenAI’s broader infrastructure update.

What is known, and what remains unconfirmed

The announcements establish the original target, the proposed investment ceiling and deployment-linked mechanism, the first-gigawatt target, and OpenAI’s later public description of a $30 billion NVIDIA investment and 5 gigawatts of Vera Rubin capacity. They do not provide a full operational audit or settle all legal and scheduling details.

  • The full amount, if any, invested under the original up-to-$100-billion proposal is not established by these announcements.
  • The final legal terms of the September 2025 letter of intent and its exact relationship to the February 2026 investment are not stated.
  • The materials do not confirm completed gigawatts, installed GPU totals, actual electricity draw, final sites, power contracts, or construction schedules.
  • They do not establish whether the original 10-GW plan remains in full, or how its scope relates to the later 5-GW Vera Rubin description.

These distinctions matter: announced is not the same as committed under a final agreement, and a target is not the same as deployed or operational capacity. The phrase “on the path to superintelligence” is an expression of corporate ambition, not evidence of a technical result or guaranteed breakthrough.
