A major transaction is set to transform the artificial intelligence sector: Nvidia is negotiating financial assurances totaling roughly $250 billion for OpenAI, according to The Wall Street Journal. This arrangement aims to enable a vast infrastructure initiative for a data center projected to exceed $500 billion in overall expenses, encompassing the chips installed there.

Sources close to the discussions indicate that Nvidia's backing would allow the creator of ChatGPT to secure a 10-gigawatt facility developed by SoftBank's energy arm in southern Ohio. The agreement would mark a key advance for both firms, granting OpenAI greater autonomy over its own infrastructure instead of depending on rentals from Microsoft, Amazon, or Oracle, while securing long-term chip demand for Nvidia.

The $250 billion commitment covers leasing and debt aspects of the data center but excludes the Nvidia chips to be deployed. Reports also note parallel talks for up to $350 billion in additional financing to support OpenAI's chip acquisitions, with Nvidia's involvement intended to reassure lenders and stabilize project finances.

The initial stage is slated for completion in 2028, delivering about 800 megawatts. Power supply falls under US government oversight and receives separate funding from Japan via a new trade pact tied to Tokyo's $33 billion commitment for a natural gas plant. US Commerce Secretary Howard Lutnick plays a central role in allocating access to these energy resources.

OpenAI has held advanced negotiations for weeks to lease the location and ranks among the most interested parties, with other major firms including Anthropic, Microsoft, and Google also engaging Lutnick recently.

This development highlights a growing pattern in technology markets where leading companies increasingly rely on debt and capital markets to finance AI infrastructure, with total spending forecast to surpass $700 billion this year.
