What the Stargate program is and where the Ohio site fits
Stargate is OpenAI's 500 billion dollar infrastructure program announced in January 2025 in partnership with SoftBank, Oracle, and MGX. The program aims to build 10 gigawatts of AI data center capacity over four years. The Ohio project is the largest Stargate site to date, and other Stargate projects are in Texas, New Mexico, and the UAE. OpenAI needs this capacity to train and serve next-generation AI models, and the geographic spread reduces regulatory and grid-risk concentration in any single US state.
The Stargate structure is unique in that the financial backstops and equity sponsors are split across multiple counterparties. OpenAI provides the demand and the operational expertise, SoftBank provides the project-level debt and renewable energy infrastructure through SB Energy, NVIDIA provides the GPU supply and a 20-year backstop on the lease payments, and Oracle and MGX provide additional capital and operational support. The structure is designed to keep OpenAI's balance sheet from absorbing the full capex of a project that exceeds the GDP of most US states.
NVIDIA role and the backstop guarantee
NVIDIA is providing a 20-year backstop guarantee for the OpenAI Ohio data center. The backstop means NVIDIA guarantees OpenAI's lease payments to SoftBank and the project financiers. If OpenAI cannot make the payments, NVIDIA steps in. The structure is needed because the 500 billion dollar project is too large for OpenAI to finance on its own, and SoftBank's SB Energy requires a creditworthy counterparty for the long-term power purchase agreements.
NVIDIA's stock fell 5 percent on the initial Wall Street Journal report in August 2026, then recovered when the deal was finalized on August 17. The motivation for NVIDIA is to lock in massive GPU demand for the Vera Rubin platform. The deal also signals that NVIDIA sees the AI infrastructure cycle as a multi-decade capital commitment, not a quarterly GPU sales story.
Why SoftBank SB Energy is financing the deal
SoftBank's SB Energy is a renewable energy infrastructure company providing project financing for the Ohio data center in exchange for long-term power purchase agreements. SB Energy will also build the on-site solar and storage to power the data center. SoftBank has been a key partner in OpenAI's Stargate program since January 2025. The deal creates a massive anchor customer for SoftBank's renewable energy business and ties the financing to a 20-year revenue stream backed by OpenAI and NVIDIA.
Economic impact on Ohio
The Ohio data center is expected to create 10,000 construction jobs during the four-year buildout and 1,000 permanent operations jobs, per the Ohio Department of Development. The project is also expected to generate 2 to 3 billion US dollars in annual economic impact, new tax revenue for the state, and new infrastructure improvements for roads, water, and power. Ohio offered tax incentives worth an estimated 1.5 billion dollars to secure the project. Other states, including Texas, Virginia, and Arizona, competed aggressively for the project.
Environmental and community concerns
The 10GW data center has raised five environmental and community concerns. First, power grid impact: 10GW is more than the entire state of Ohio consumes during peak hours, requiring substantial grid upgrades. Second, water use: data center cooling requires millions of gallons of water, straining local supplies. Third, land use: more than 1,000 acres of federal land will be developed. Fourth, noise: data center fans and cooling towers create constant low-frequency noise. Fifth, light pollution: 24/7 operations create persistent light spillover.
OpenAI has committed to 100 percent renewable energy for the project and a water-efficient cooling design, per OpenAI's 2026 sustainability disclosure. The company is also working with the Department of Energy on grid upgrade coordination and with local utilities on-site solar and battery storage to reduce transmission load.
How the deal fits the broader AI infrastructure race
- OpenAI Stargate: 500 billion dollars, 10GW across multiple sites.
- NVIDIA: 20-year backstop on OpenAI, 100 billion dollar investment in OpenAI.
- Microsoft: 80 billion dollar AI infrastructure spend in 2025, owns the OpenAI Azure relationship.
- Meta: 60 to 65 billion dollar AI infrastructure spend in 2025, building 1.5GW+ data centers.
- Amazon AWS: 90 billion dollar AI infrastructure spend, Trainium and NVIDIA chips.
- Google: 75 billion dollar AI infrastructure spend, TPU and NVIDIA chips.
- SoftBank: 500 billion dollar Stargate investment, SB Energy infrastructure financing.
What this means for the AI industry in 2026
The OpenAI Ohio data center signals continued massive AI infrastructure investment despite recent market uncertainty. The scale of the project, 500 billion dollars over 20 years, is unprecedented in the technology industry. The deal also signals OpenAI's commitment to remaining independent of any single cloud provider, NVIDIA's strategic investment in OpenAI to lock in long-term GPU demand, the continuing arms race between AI labs for compute, the increasing role of sovereign and corporate financing for AI infrastructure, and the growing geopolitical importance of AI compute as a strategic resource.
