OpenAI is close to securing a landmark $500 billion data center in southern Ohio, a project poised to become one of the largest artificial intelligence infrastructure investments in the U.S. According to three sources familiar with the deal, the initiative involves a $250 billion financial backstop from chipmaker Nvidia, providing critical capital and risk mitigation.
The U.S. government, partnering with Japan through a bilateral agreement to supply energy, is finalizing terms, with Commerce Secretary Howard Lutnick awaiting final approval. SoftBank, a key OpenAI investor, leads the development of the facility, which will be constructed on federal land at a decommissioned Cold War-era uranium enrichment plant in Piketon, approximately 50 miles south of Columbus. The center will draw power from a 10-gigawatt energy grid, sufficient to supply millions of U.S. households.
The project exemplifies the intricate financial ecosystems driving the AI boom, where startups like OpenAI and Anthropic rely on partnerships with tech giants and governments to access computing resources. These arrangements often involve circular investments—companies receive billions from cloud providers, then redirect funds to purchase computing capacity. For instance, Microsoft has invested over $13 billion in OpenAI since 2019, much of which OpenAI subsequently funneled back to Microsoft for cloud services. Similar dynamics exist between Anthropic and Google, and Google’s investments have contributed to its recent 24% revenue growth, bolstered by stakes in SpaceX and Anthropic, generating $77 billion in profit.
Nvidia’s involvement enhances OpenAI’s financial stability by offering favorable debt terms and covering lease payments if the startup defaults. With a $3 trillion market valuation, Nvidia can secure lower interest rates and guarantee investments, reducing risks for lenders, said University of Michigan law professor Jeremy Kress. “It’s reassuring to have stable capital backing such a critical venture,” he noted.
Financial analysts caution that such mega-projects carry systemic risks. Gil Luria of D.A. Davidson warned, “$500 billion is unprecedented—its viability hinges on substantial returns and long-term sustainability.” Even Nvidia’s support is not without peril, as Kress emphasized that OpenAI’s debt troubles could signal broader AI sector distress, directly impacting Nvidia’s fortunes.
Other potential users of the Ohio facility include Microsoft, Google, and unnamed competitors. The Japanese government’s contribution via tariff reduction agreements highlights geopolitical investments in U.S. infrastructure. Completion timelines remain uncertain, with the first phase projected for 2028. Meanwhile, investment firms like Blackstone have already profited from AI-related assets, including data centers and energy infrastructure, reflecting the sector’s rapid growth.
“This transformation will redefine industries and markets for generations,” stated Blackstone CEO Stephen Schwarzman during its earnings call.
