Nvidia Eyes $250B Backstop for OpenAI Data Center
The author argues that recent large-scale, off‑balance-sheet financing in the GenAI sector is increasingly viewed with skepticism. He recalls Oracle’s September 2025 $300 billion data-deal with OpenAI and the subsequent stock volatility, and reports that Nvidia is reportedly considering a $250 billion financing backstop for an OpenAI-led data center project (reportedly tied to a SoftBank Ohio 10GW lease). Markets reacted negatively to the Nvidia news, with early trading showing a notable drop in Nvidia shares. The piece highlights wider market wariness, creditor concern, and the broader idea of “circular” or “creative” financing sustaining the GenAI boom rather than profits.
Large potential financing by major tech firms (Nvidia/OpenAI) signals market skepticism about how the GenAI boom is funded and could affect capital allocation for cloud, chip, and data-center infrastructure across the tech ecosystem.

Jim Cramer: AI financing echoes dot‑com bubble
Jim Cramer warned that recent AI financing arrangements, highlighted by reports that Nvidia discussed a potential $250 billion backstop for OpenAI’s planned 10-gigawatt data center campus, revive memories of the supplier-customer financing that preceded the dot-com crash. CNBC confirmed the Wall Street Journal report and said Nvidia declined to comment. The article notes Nvidia’s prior investments in AI companies — including $30 billion in OpenAI and $10 billion in Anthropic — and highlights the circular nature of some AI financing where suppliers invest in or guarantee deals for major customers. Cramer said Nvidia remains strong but cautioned that supplier-backed financing can quickly unravel if buyers can’t pay. The piece also notes OpenAI confidentially filed for an IPO and was recently valued at over $800 billion by private investors.
Nvidia Negotiates $250B Guarantee for OpenAI
Reports say Nvidia is negotiating a roughly $250 billion financing guarantee to let OpenAI lease and develop a proposed 10-gigawatt AI data-center campus in Pike County, Ohio, led by a SoftBank/SB Energy subsidiary with U.S. Department of Energy involvement. The campus could exceed $500 billion in total costs, with a SoftBank unit handling power and Japan reportedly offering about $33 billion in financing tied to lower U.S. tariffs; the first phase is targeted by 2028. The proposed backstop would allow OpenAI to raise lease and construction debt on Nvidia’s credit but would not cover Nvidia chips. Separately, Nvidia is reportedly weighing financing up to $350 billion of chip purchases for OpenAI. The talks are ongoing, have prompted market moves, and Nvidia and OpenAI have not publicly commented.
Nvidia Rally: Three Reasons It Can Continue
Nvidia's shares have rebounded ahead of its fiscal 2027 Q2 results, driven by reduced perceived risk around its financial support for AI infrastructure, a new large financing initiative, and strong revenue momentum at major AI labs. Nvidia announced support for an Ohio data-center project where OpenAI will be a 20-year tenant and will be the exclusive compute provider; the company's backstop for the initial 4.25-gigawatt build is reported at $105 billion and includes a $1.5 billion investment in SB Energy. Nvidia also unveiled a roughly $500 billion financing initiative with Wall Street firms (Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs and KKR) to securitize compute, shifting funding risk to institutional investors. Bloomberg and other outlets reported rapidly growing annualized revenue at OpenAI (~$40 billion) and Anthropic (>$11.5 billion annualized), which eases counterparty concerns around future compute spend.
