Nvidia Just Cosigned OpenAI's Lease. That's the Story.
A $105 billion guarantee on a data center Nvidia doesn't own, for a tenant it doesn't own, delivering compute in 2028. The financing structure is the news, not the gigawatts.
- August 17: Nvidia guaranteed up to $105 billion in conditional lease and power obligations for OpenAI's campus at PORTS-Pike in Pike County, Ohio.
- 4.25 IT-GW in phase one with an option on the remaining 3.75 IT-GW, for 8 IT-GW total. Nvidia also puts $1.5 billion of equity into SB Energy and is the exclusive compute supplier.
- SB Energy and SoftBank fund at least 10 GW of new generation plus $4.2 billion into regional grid infrastructure, with an $80 million community benefits fund.
- Capacity comes online in phases starting in 2028 — and the guarantee shrank from a reported ~$250 billion to under $120 billion before landing at $105 billion.
On August 17, 2026, Nvidia agreed to guarantee up to $105 billion in conditional lease and power payment obligations for an OpenAI data center at SB Energy's PORTS-Pike Technology Campus in Pike County, Ohio. The campus is designed for 8 IT-gigawatts, starting with 4.25 IT-GW, with capacity deploying in phases beginning in 2028.
Monday. Nvidia guaranteed up to $105 billion in lease and power obligations for a data center it does not own, for a tenant it does not own, on the grounds of a retired uranium enrichment plant in Pike County, Ohio.
Nvidia isn’t the landlord here. It isn’t the tenant. It’s the cosigner.
I spent years in Ops watching people confuse announced capacity with available capacity. So let me pull the actual numbers out before anybody starts writing takes about the end of compute scarcity.
What actually got committed
Straight from Nvidia’s release:
- SB Energy builds and operates the PORTS-Pike Technology Campus. OpenAI is the designated customer.
- 4.25 IT-GW in the first tranche, with an option on the remaining 3.75 IT-GW. Campus design: 8 IT-GW.
- Nvidia puts $1.5 billion of equity into SB Energy and becomes the exclusive compute supplier.
- SB Energy and SoftBank stand up at least 10 GW of new generation and put at least $4.2 billion into regional grid infrastructure.
- $80 million community benefits fund.
- Capacity deploys in phases starting in 2028.
- That’s the number missing from every headline I read Monday night.
The number moved twice on its way to the podium
This deal didn’t arrive at $105 billion. It walked there.
CNBC reported Nvidia was discussing a backstop up to $250 billion. Then the Wall Street Journal reported it was getting cut to under $120 billion. Then the filing said $105 billion, capped, conditional.
Every checkpoint went the same direction. Down.
That’s not a scandal, but it is information. When a company trims its own contingent exposure by more than half before the ink dries, the market read on that exposure was not “give us more.”
The cosigner problem, said plainly
Nvidia is the chip seller. Nvidia is an equity holder in the site operator. Nvidia is the credit behind the tenant’s rent. Three hats, one head.
Wall Street was already asking about this six days before the announcement, and the announcement didn’t answer it. Mizuho’s traders put it about as cleanly as anybody: the structure doesn’t tell you how much end-user demand sits underneath the spending.
Let me be fair, though, because the “it’s all fake demand” crowd is overplaying its hand. A conditional guarantee is not a purchase order. Nvidia hasn’t shipped $105 billion of anything. It has agreed to be liable if obligations go unpaid. And somebody genuinely has to finance power and shell before anyone can rent a GPU. Land and megawatts are the bottleneck now, not silicon — Jensen said as much, and on that specific point he’s right.
The honest read is neither “bubble confirmed” nor “demand validated.” It’s this: frontier compute is now financed on vendor credit instead of customer cash flow. That’s a real structural change and it’s worth naming without a verdict attached to it yet.
What this means at your desk
Nothing. This week, nothing.
Not a single token gets cheaper, not one rate limit loosens, and no queue drains because of Monday. This is a 2028 story wearing a 2026 press release. Same discipline I’ve been preaching through the whole systems race — plan against the compute you can actually purchase this quarter, not the compute somebody financed for the back half of the decade.
Axios put the scale in terms that stuck with me: Ohio’s entire summer power capacity runs around 30 GW. This one campus wants 10 GW of new generation on top of that. If you’re anywhere near a production AI stack, your real risk isn’t model quality. It’s regional power, and it’s a permitting fight, and it’s slower than any roadmap slide.
Build for the quarter. Let them build for the decade.

Bottom lineThis is the largest AI infrastructure commitment ever disclosed, and it is also the clearest sign yet that frontier compute now runs on vendor credit instead of customer cash. Nothing here changes your token bill before 2028. Build for the compute you can buy this quarter.
