OpenAI's 8-Gigawatt Ohio AI Campus: The NVIDIA and SB Energy Deal, Explained by the Numbers
Eight gigawatts. That is the total information-technology capacity OpenAI has committed to absorb as the sole customer of the PORTS-Pike Technology Campus in Pike County, Ohio — a single site that will exclusively host NVIDIA AI compute, built and owned by SB Energy under a 20-year lease with OpenAI, with NVIDIA providing credit support to lock in the first 4.25 gigawatts and an option on the remaining 3.75. Announced August 17, 2026, it is one of the largest single-site AI infrastructure commitments ever disclosed, and nearly every headline number in it deserves a closer look.
Where the Numbers Come From
The figures below come from NVIDIA's official newsroom statement published August 17, 2026, supplemented by OpenAI's companion post announcing its participation in the PORTS-Pike project. Wire coverage from Reuters, Bloomberg, and CNBC followed the same day. Where a number circulates in the press but does not appear in the official statement, we say so explicitly.
The Official Numbers, In One Table
| Figure | What it measures | Source |
|---|---|---|
| 8 IT-GW | Total IT capacity; OpenAI is the full-capacity customer | Official NVIDIA statement |
| 20 years | Lease term between OpenAI and SB Energy | Official NVIDIA statement |
| 4.25 GW | Initial capacity secured with NVIDIA credit support for land, power, and structure | Official NVIDIA statement |
| 3.75 GW | Remaining capacity under option | Official NVIDIA statement |
| $1.5 billion | NVIDIA investment in SB Energy, joining SoftBank Group and OpenAI as investors | Official NVIDIA statement |
| 10+ GW | New generation capacity from SB Energy/SoftBank | Official NVIDIA statement |
| $4.2 billion+ | New regional grid investments with AEP Ohio to protect consumers | Official NVIDIA statement |
| $80 million | Community benefits fund: $40M from SB Energy + $40M from OpenAI | Official NVIDIA statement |
| Tens of thousands | Jobs projected in Ohio | Official NVIDIA statement |
| 2028 | Phased operations begin | Official NVIDIA statement |
One number requires a caveat. Several outlets, including Reuters and Bloomberg, reported a guarantee worth "up to $105 billion." That figure does not appear in the text of NVIDIA's official statement, so treat it as press-reported context rather than a confirmed contract value.

Who Does What: The Structure of the Deal
The campus sits on the site of the former Portsmouth Gaseous Diffusion Plant in Appalachian Ohio, across private and federal land, in coordination with AEP Ohio, the U.S. Department of Energy, and the U.S. Department of Commerce. The division of labor is unusual in how cleanly it separates roles:
- SB Energy builds, owns, and operates the data center.
- OpenAI leases the entire 8 GW of IT capacity for 20 years.
- NVIDIA guarantees the site exclusively hosts its AI compute, supplies the full NVIDIA DSX platform (GPUs, CPUs, networking), and provides credit support for the land, power, and shell so the first 4.25 GW can be financed.
- SoftBank appears on two sides: as an investor in SB Energy alongside NVIDIA's $1.5 billion, and as a partner in the 10+ GW of new generation.
The advisors read like a merger: Goldman Sachs and JP Morgan for SB Energy, Morgan Stanley for NVIDIA. Jensen Huang framed the logic in one line — AI is becoming infrastructure, and NVIDIA is securing long-lived infrastructure for its compute. Sam Altman pointed to compute "for millions of people" and pride in building in Pike County. Rich Housfeld, co-CEO of SB Energy, emphasized energy-first infrastructure at unprecedented scale, consumer protection, and tens of thousands of jobs.
Why a Former Uranium Site Matters
The Portsmouth plant choice is not sentimental. Former gaseous diffusion sites offer large contiguous land, existing transmission interconnections, and a federal redevelopment pathway — exactly the profile hyperscale AI campuses need. For Appalachian Ohio, a region that has watched industrial jobs leave for decades, the $80 million community benefits fund (split evenly between SB Energy and OpenAI) targets affordable energy, jobs, and community development. The $4.2 billion in grid investments with AEP Ohio is framed explicitly as consumer protection, an acknowledgment that 8 GW of new demand cannot land on a regional grid without consequences for residential bills.
Quick Comparison: How This Deal Is Structured
| Element | PORTS-Pike model | Traditional hyperscale model |
|---|---|---|
| Ownership | SB Energy builds, owns, operates | Cloud provider owns |
| Customer | OpenAI leases 100% for 20 years | Capacity shared across cloud customers |
| Compute | Exclusively NVIDIA (full DSX platform) | Mixed vendor hardware |
| Financing | NVIDIA credit support + $1.5B equity in SB Energy | Balance-sheet funded |
| Energy | 10+ GW new generation from SB Energy/SoftBank | Procured from existing grid/utility PPAs |
| Community | $80M benefits fund + $4.2B grid investment | Varies by project |
What This Means for You
If you are a student, developer, or researcher in Lagos, Bengaluru, Manila, Jakarta, Karachi, São Paulo, Ho Chi Minh City, Warsaw, or Dubai, the direct connection is capacity. Eight gigawatts of compute dedicated to OpenAI under a 20-year lease exists to serve growing global demand for AI services — the kind of demand that currently produces rate limits and queues during peak hours in every time zone. More capacity coming online in phases from 2028 means the services you use for study, research, and work have a longer runway. For context on how fast the inference race is moving, see our coverage of Cerebras and GPT-5.6 Sol Ultrafast; infrastructure and speed are now the same competition. And if you are weighing a career in AI or energy systems, this project is a signal about where tens of thousands of jobs will be created — browse https://truescho.com/en/rankings to compare universities strong in engineering and computer science.
OpenAI has not announced any international expansion tied to this campus, and NVIDIA has not announced customer pricing or specific services that will run on PORTS-Pike capacity. Nothing in the statement commits to availability in any particular country — what it commits to is raw capacity, exclusively on NVIDIA hardware, for one customer.

The Bigger Capital Picture
PORTS-Pike is one tile in a much larger mosaic. On August 10, 2026, NVIDIA announced partnerships with Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs, KKR, and others to mobilize more than $500 billion in external capital for AI infrastructure. The Ohio deal shows the template: NVIDIA does not just sell chips, it uses its balance sheet — here, credit support plus a $1.5 billion equity stake — to make gigawatt-scale projects financeable, then guarantees the resulting compute runs on its platform. That vertically-integrated financing posture is arguably a bigger story than any single campus.
Honest Limitations of This Announcement
- Phased, not instant. Operations begin in phases from 2028; the campus does not serve users tomorrow, and the 3.75 GW option may never be exercised on the announced timeline.
- Jobs are a projection. "Tens of thousands" is a company estimate, not a verified employment figure.
- No consumer details. Neither OpenAI nor NVIDIA has announced which products, prices, or regions this capacity will serve.
- Unverified figures circulate. The "up to $105 billion" guarantee is press-reported, not in the official statement.
- Energy promises are forward-looking. The 10+ GW of generation and $4.2 billion of grid investment depend on execution over many years.
- Security is a separate conversation. Massive centralized compute raises protection questions of its own — our coverage of Wiz Red Agent and the Snowflake incident is relevant background.
Questions Readers Are Asking
What is the OpenAI Nvidia Ohio data center deal?
It is a 20-year agreement under which SB Energy builds, owns, and operates the PORTS-Pike Technology Campus in Pike County, Ohio, while OpenAI leases the site's full 8 gigawatts of IT capacity. NVIDIA guarantees the campus exclusively hosts its AI compute and supports financing for the first 4.25 gigawatts, with an option on the remaining 3.75.
Who owns the OpenAI Ohio data center?
SB Energy owns and operates it. OpenAI is the tenant, not the owner, and NVIDIA is the compute supplier and a financial backer — including a $1.5 billion investment in SB Energy alongside SoftBank Group and OpenAI. The structure keeps ownership, operations, and consumption in three separate hands.
When will the Pike County AI campus go online?
NVIDIA's statement says phased operations begin in 2028. The company has not published a detailed schedule for when the initial 4.25 gigawatts reach full utilization, or when the 3.75-gigawatt option would be exercised. Treat 2028 as a starting point, not a completion date.
How much is Nvidia investing in SB Energy?
NVIDIA is investing $1.5 billion in SB Energy, joining SoftBank Group and OpenAI as investors. Separately, NVIDIA is providing credit support for the land, power, and shell needed to secure the initial 4.25 gigawatts. The $1.5 billion figure is equity; the credit support is an additional commitment.
Why did OpenAI sign a 20-year lease in Ohio?
OpenAI has not publicly detailed its reasoning beyond Sam Altman's statement about massive compute for millions of people. Practically, a 20-year lease locks in capacity amid global compute scarcity, and the NVIDIA credit structure and existing energy infrastructure at the former Portsmouth site made a gigawatt-scale commitment financeable.
What to Watch Next
Three signals will tell you whether PORTS-Pike is transformational or transitional. First, whether the 3.75-gigawatt option gets exercised and when — that is the difference between a very large campus and an unprecedented one. Second, whether the 2028 phased start holds; multi-year energy and grid projects in the AI sector have slipped before, and the $4.2 billion AEP Ohio investment will be the leading indicator. Third, whether the financing template — chipmaker credit support plus equity in the developer plus an exclusive compute guarantee — gets replicated; NVIDIA's $500 billion capital partnerships suggest it will, and each replication will move the global compute ceiling that students and developers in every country actually feel. Watch also for OpenAI's next capacity announcement: if the company is committing 20-year leases at 8-gigawatt scale, it is planning for demand several multiples of today's, and that assumption — more than any single number in this deal — is the bet everything else depends on.
