Nvidia Guarantees $105 Billion for OpenAI's Ohio Data Center 2026
A payment guarantee is a financial promise in which a third party agrees to cover a bill if the original borrower cannot. That old-fashioned finance tool just landed at the center of the AI industry: Nvidia has agreed to guarantee up to $105 billion in lease and power payments for OpenAI's newest data center. A chip company is now underwriting its own customer's rent, a structure rarely seen at this scale.
An 8GW Campus On A Former Uranium Site
On August 17, 2026, OpenAI, Nvidia, and SoftBank's SB Energy announced the "PORTS-Pike Technology Campus" in Ohio, built on a former Cold War-era uranium-enrichment site. Computing capacity starts at 4.25 gigawatts (GW) and can scale to 8GW with an expansion option, enough power to match roughly eight nuclear reactors. Construction is expected to create 35,000 jobs, with 2,500 permanent roles once the campus goes live in 2028.
How The Nvidia Guarantee Actually Works
The deal is a three-way structure. SB Energy builds and owns the campus, and OpenAI signs on as tenant for 20 years. Nvidia's role is the backstop: if OpenAI cannot cover its lease or power payments, Nvidia conditionally guarantees up to $105 billion to keep the project funded. Nvidia is also investing $1.5 billion directly in SB Energy and will be the exclusive chip supplier for the entire campus, while SB Energy commits at least $4.2 billion to regional grid upgrades.
Why This Signals A Shift In AI Infrastructure
The arrangement has drawn criticism as circular financing, where a supplier effectively funds the demand for its own products. Nvidia CEO Jensen Huang pushed back, saying OpenAI is the one paying the lease, and compared it to standard supply-chain planning. Beyond the debate, the deal shows where competitive advantage in AI is heading: not just who builds the fastest chip, but who can underwrite gigawatts of power and decades of debt. Broadcom's reported pursuit of over $60 billion in AI-related debt financing around the same week suggests this is becoming an industry pattern, not a one-off.
Key Takeaways
① $105 billion guarantee - Nvidia will conditionally cover OpenAI's lease and power payments up to this cap.
② 8GW campus - SB Energy builds it, OpenAI leases it for 20 years, first power in 2028.
③ Power over chips - Credit and electricity supply are becoming the real competitive edge in AI infrastructure.
AI competition is no longer only about model quality or chip speed. It now runs through who can mobilize enough capital and power to keep the buildout going, and Nvidia's guarantee is the clearest marker yet of that shift.
