Nvidia is in talks to guarantee roughly $250 billion of lease and construction debt obligations tied to OpenAI's planned 10 gigawatt data center campus in southern Ohio, according to a Wall Street Journal report published on 27 July 2026; the talks are ongoing, nothing is signed, and the report has not been independently confirmed by other outlets with their own sourcing.1 The Next Web 2026-07-27 Citing the Wall Street Journal: Nvidia in talks to guarantee about $250 billion of OpenAI Ohio lease and construction debt, separate chip financing of about $350 billion, total cost above $500 billion, 800 MW first phase in 2028, OpenAI without investment grade credit, Nvidia $30 billion OpenAI exposure, Google guaranteeing about $44 billion of rent, $3 trillion data center spend through 2028, nothing signed. Open source The same day, Nvidia and Ilya Sutskever's Safe Superintelligence announced a long term partnership in which Nvidia makes a substantial investment, reported by Bloomberg at about $5 billion though neither company confirmed a figure, and SSI gains access to Nvidia's Vera Rubin platform.3 Nvidia press release 2026-07-27 Long term strategic partnership announced 27 July 2026: substantial Nvidia investment of undisclosed size, SSI access to the Vera Rubin platform for an order of magnitude more compute, quotes from Jensen Huang and Ilya Sutskever.

Open source The stake is the structure of the AI buildout itself: the world's most valuable chipmaker is moving from selling compute to guaranteeing the credit of the companies that buy it. We assess with high confidence that Nvidia is deliberately converting its balance sheet into the credit backbone of its largest customers' expansion, and with moderate confidence that the Ohio guarantee closes in something near its reported size, since the talks are unfinished and single sourced.

Why a chipmaker is writing a credit guarantee

The mechanics, as reported, are blunt. OpenAI wants to lease a campus in Pike Township, Ohio, about 109 kilometers south of Columbus, being developed by SoftBank's energy subsidiary SB Energy, with a first phase of roughly 800 megawatts targeted for 2028 and a reported potential 20 year lease.2 UA.NEWS 2026-07-27 Campus in Pike Township, Ohio, about 109 km south of Columbus, developed by SoftBank subsidiary SB Energy, up to 800 megawatts by 2028, reported potential 20 year lease, chip costs an additional $350 billion, OpenAI operating at a loss. Open source The full development could eventually cost more than $500 billion including the Nvidia chips inside it.1 The Next Web 2026-07-27 Citing the Wall Street Journal: Nvidia in talks to guarantee about $250 billion of OpenAI Ohio lease and construction debt, separate chip financing of about $350 billion, total cost above $500 billion, 800 MW first phase in 2028, OpenAI without investment grade credit, Nvidia $30 billion OpenAI exposure, Google guaranteeing about $44 billion of rent, $3 trillion data center spend through 2028, nothing signed. Open source OpenAI lacks an investment grade credit rating and operates at a loss, so lenders financing the construction and the lease want a counterparty they trust.1 The Next Web 2026-07-27 Citing the Wall Street Journal: Nvidia in talks to guarantee about $250 billion of OpenAI Ohio lease and construction debt, separate chip financing of about $350 billion, total cost above $500 billion, 800 MW first phase in 2028, OpenAI without investment grade credit, Nvidia $30 billion OpenAI exposure, Google guaranteeing about $44 billion of rent, $3 trillion data center spend through 2028, nothing signed.

The fact worth holding onto is what this arrangement says about the debt markets. A guarantee of this size is only necessary if lenders will not extend the money against OpenAI's own name at an acceptable price. That is a market verdict on the borrower, and the workaround is to substitute Nvidia's credit for OpenAI's. Nvidia has already committed more than $40 billion in AI equity positions, including roughly $30 billion tied to OpenAI, and it is not alone in this behavior: Google has guaranteed about $44 billion of other companies' data center rent.1 The Next Web 2026-07-27 Citing the Wall Street Journal: Nvidia in talks to guarantee about $250 billion of OpenAI Ohio lease and construction debt, separate chip financing of about $350 billion, total cost above $500 billion, 800 MW first phase in 2028, OpenAI without investment grade credit, Nvidia $30 billion OpenAI exposure, Google guaranteeing about $44 billion of rent, $3 trillion data center spend through 2028, nothing signed.

Open source We assess with high confidence that credit enhancement by the sellers of compute, not equity from the buyers of it, is now the marginal source of financing for the largest AI campuses, because the reported numbers dwarf what any AI lab's own balance sheet can carry.

The same day, billions for a lab with no product

The SSI deal is the same strategy at the other end of the risk curve. Nvidia's own release describes a substantial investment and a long term partnership in which SSI deploys the Vera Rubin platform for an order of magnitude increase in its compute, with Jensen Huang saying he is excited to see "what new breakthroughs SSI will discover" on it.3 Nvidia press release 2026-07-27 Long term strategic partnership announced 27 July 2026: substantial Nvidia investment of undisclosed size, SSI access to the Vera Rubin platform for an order of magnitude more compute, quotes from Jensen Huang and Ilya Sutskever.

Read together, the two announcements bracket Nvidia's position. With OpenAI it is backstopping the debt of its largest customer; with SSI it is funding a pre revenue lab whose main expenditure will be Nvidia hardware. Both transactions convert Nvidia cash or Nvidia credit into future Nvidia demand. The circularity criticism writes itself, and it circulated the same day: money leaves Nvidia, buys Nvidia chips, and returns as Nvidia revenue, which flatters growth while concentrating risk.5 Trending Topics 2026-07-27 Neither company confirmed the investment size; SSI has no product or revenue, a $32 billion valuation and about $7 billion raised; Nvidia AI portfolio spans OpenAI, xAI, Anthropic, CoreWeave, Nebius, Nscale and Lambda; circular financing concerns that Jensen Huang disputes.

Open source We assess with moderate confidence that the circularity is real but rational from Nvidia's seat: the alternative to financing demand is watching it fail to materialize, and Nvidia's margin on the chips gives it a cushion no outside lender enjoys.

Who gains and who loses

SoftBank and SB Energy gain most directly: a lease guaranteed by Nvidia is bankable paper, which is what lets a $500 billion campus get financed at all.1 The Next Web 2026-07-27 Citing the Wall Street Journal: Nvidia in talks to guarantee about $250 billion of OpenAI Ohio lease and construction debt, separate chip financing of about $350 billion, total cost above $500 billion, 800 MW first phase in 2028, OpenAI without investment grade credit, Nvidia $30 billion OpenAI exposure, Google guaranteeing about $44 billion of rent, $3 trillion data center spend through 2028, nothing signed.

Open source

The losers are quieter. Nvidia shareholders absorb counterparty risk that does not show up in revenue multiples: a guarantee pays out exactly when the customer is failing, which is also when Nvidia's own sales would be falling, so the exposure is correlated with the downside it is meant to prevent. Rival chipmakers lose twice, because financing tied to Nvidia silicon locks campuses and labs into Nvidia's platform for the life of the lease. And any smaller AI company that cannot summon a trillion dollar guarantor now competes for capital in a market where the biggest borrowers do not need to be creditworthy, only well connected. That last point is an assessment, but it follows directly from the reported structure.1 The Next Web 2026-07-27 Citing the Wall Street Journal: Nvidia in talks to guarantee about $250 billion of OpenAI Ohio lease and construction debt, separate chip financing of about $350 billion, total cost above $500 billion, 800 MW first phase in 2028, OpenAI without investment grade credit, Nvidia $30 billion OpenAI exposure, Google guaranteeing about $44 billion of rent, $3 trillion data center spend through 2028, nothing signed. Open source

The counter-case

The thesis could fail in two ways. First, the deal may simply not close at anything like $250 billion. The reporting is explicit that terms are unfinalized and completion is uncertain, and it rests on a single outlet's sourcing.1 The Next Web 2026-07-27 Citing the Wall Street Journal: Nvidia in talks to guarantee about $250 billion of OpenAI Ohio lease and construction debt, separate chip financing of about $350 billion, total cost above $500 billion, 800 MW first phase in 2028, OpenAI without investment grade credit, Nvidia $30 billion OpenAI exposure, Google guaranteeing about $44 billion of rent, $3 trillion data center spend through 2028, nothing signed. Open source A guarantee that lands at a fraction of the figure, or fragmented across phases with strict conditions, would make this an ordinary vendor finance story rather than a structural shift. Second, the benign reading may be right: Nvidia generates enormous cash flow, the guarantee only costs money if OpenAI defaults on a campus filled with productive hardware, and equipment makers have financed customers in every capital intensive buildout in history. For the pessimistic reading to win, OpenAI's losses would need to persist at scale into the 2028 delivery window while demand for its services undershoots the capacity being built.2 UA.NEWS 2026-07-27 Campus in Pike Township, Ohio, about 109 km south of Columbus, developed by SoftBank subsidiary SB Energy, up to 800 megawatts by 2028, reported potential 20 year lease, chip costs an additional $350 billion, OpenAI operating at a loss. Open source If instead OpenAI grows into the lease, the guarantee expires unused and Nvidia will have bought market lock in for free.

What to watch

  • Whether the guarantee is confirmed and at what size. A signed agreement, disclosed by the companies or in Nvidia's filings by the end of 2026, at or near $250 billion validates the report; silence into 2027 or a materially smaller figure argues the talks stalled.1 The Next Web 2026-07-27 Citing the Wall Street Journal: Nvidia in talks to guarantee about $250 billion of OpenAI Ohio lease and construction debt, separate chip financing of about $350 billion, total cost above $500 billion, 800 MW first phase in 2028, OpenAI without investment grade credit, Nvidia $30 billion OpenAI exposure, Google guaranteeing about $44 billion of rent, $3 trillion data center spend through 2028, nothing signed. Open source
  • The $350 billion chip financing structure. If the separate chip purchase financing surfaces as a concrete instrument within two quarters, Nvidia's lender role is policy, not a one off.1 The Next Web 2026-07-27 Citing the Wall Street Journal: Nvidia in talks to guarantee about $250 billion of OpenAI Ohio lease and construction debt, separate chip financing of about $350 billion, total cost above $500 billion, 800 MW first phase in 2028, OpenAI without investment grade credit, Nvidia $30 billion OpenAI exposure, Google guaranteeing about $44 billion of rent, $3 trillion data center spend through 2028, nothing signed. Open source
  • Ohio first phase power on schedule. If the campus delivers its roughly 800 megawatt first phase by 2028, the underwriting was sized to a real asset; slippage past 2028 stretches the window in which Nvidia carries the risk without the revenue.2 UA.NEWS 2026-07-27 Campus in Pike Township, Ohio, about 109 km south of Columbus, developed by SoftBank subsidiary SB Energy, up to 800 megawatts by 2028, reported potential 20 year lease, chip costs an additional $350 billion, OpenAI operating at a loss. Open source
  • The SSI number in a filing. Watch Nvidia's next quarterly disclosures for the investment's actual size; confirmation near $5 billion would make it one of the largest checks ever written to a company with no revenue, and a smaller figure would say the announcement outran the money.4 TechCrunch 2026-07-27 Investment reported by Bloomberg at about $5 billion, unconfirmed by the companies; SSI funding history of $1 billion at founding and $2 billion at a $32 billion valuation; Sutskever on research worthy of scaling up.

Open source
  • Whether other guarantors follow. Google already stands behind about $44 billion of data center rent; a second hyperscaler or chipmaker announcing a comparable backstop within a year would confirm that seller credit is now the standard financing layer of the AI buildout.1 The Next Web 2026-07-27 Citing the Wall Street Journal: Nvidia in talks to guarantee about $250 billion of OpenAI Ohio lease and construction debt, separate chip financing of about $350 billion, total cost above $500 billion, 800 MW first phase in 2028, OpenAI without investment grade credit, Nvidia $30 billion OpenAI exposure, Google guaranteeing about $44 billion of rent, $3 trillion data center spend through 2028, nothing signed.

The question the next two years answer is not whether OpenAI gets its campus. It is whether the AI economy's credit risk has been quietly consolidated onto the balance sheets of the two or three companies that profit most from its growth, which would make the sector's eventual stress test everyone's at once.
