OpenAI's Ohio AI Campus: A 9.2 GW Gas Plant and IPO Clock

Fresh details on OpenAI’s Ohio campus reveal a project of unusual scale, and the company’s CFO has now put a public-markets timeline on the record. Both developments carry direct implications for investors watching the IPO path.

Key points

• OpenAI signed a 20-year lease for roughly 8 gigawatts of capacity at the former Portsmouth Gaseous Diffusion Plant in Pike County, Ohio, backed by a $105 billion guarantee from Nvidia and developed by SoftBank’s SB Energy alongside the Department of Energy.
• The campus would draw power from a proposed 9.2-gigawatt natural gas plant, which would be the largest fossil-fuel power plant ever built in the United States.
• The Trump administration is running the federal environmental review as an “assessment” rather than a full environmental impact statement, with a completion target of December 23, roughly seven months for a facility larger than five of Ohio’s biggest existing power plants combined.
• OpenAI’s CFO told staff the company will be a public company in 2027, or sooner if the business inflects, the clearest internal timeline yet.
• OpenAI is also cutting API prices for its GPT-5.6 Sol model by over 20%, following similar cuts to its smaller Terra and Luna models last month.

What does a 9.2-gigawatt gas plant mean in practice?

The numbers are worth sitting with. Energy analyst John Bistline noted that 9.2 gigawatts of new gas generation at a single Ohio site exceeds the total generating capacity of any of ten entire states, including Montana, Idaho, Maine, Alaska, and Vermont. The full AI campus is planned at 10 gigawatts, anchored by that plant.

The site itself carries history. The Portsmouth Gaseous Diffusion Plant is a decommissioned uranium enrichment facility on federal land, a detail that longtime Ohio journalist Darrel Rowland highlighted in questioning the pace of the current review. OpenAI has framed the project as economic revival: “Pike County helped power America’s industrial growth in the 20th century and now, with this project, it has another opportunity to play a leading role in the next era of American industrialization,” the company said.

Environmental critics and energy watchers are raising two distinct concerns: the sheer scale of new fossil-fuel generation being locked in under a 20-year lease, and the speed of the federal review process. A full environmental impact statement is typically required for projects of this magnitude. Using the lighter “environmental assessment” track and targeting a December 23 completion date has drawn sharp attention from analysts who track energy permitting.

For investors, the Ohio campus represents a massive, long-dated capital commitment. The $105 billion Nvidia guarantee backstops the lease, but the project also ties OpenAI’s infrastructure strategy to a regulatory and political environment that could shift over a 20-year horizon.

What does the CFO’s 2027 IPO comment signal?

The financefeeds.com report cites OpenAI CFO Sarah Friar telling staff the company will go public in 2027, with the possibility of an earlier date if the business “inflects.” The source does not define what inflection means in specific financial terms, and the reporting is based on internal communications rather than a formal public filing.

OpenAI has already filed confidentially, so the 2027 window aligns with expectations that have been building for months. The “sooner if it inflects” framing is notable, though. It suggests management is watching a specific internal threshold, likely a revenue or margin milestone, that could accelerate the timeline. That matters against the backdrop of the company’s slowing sales growth and deepening losses reported in recent coverage, with Anthropic applying competitive pressure on pricing.

API price cuts: competitive pressure or strategy?

The over-20% price reduction on GPT-5.6 Sol continues a pattern. Terra and Luna saw cuts last month. Taken together, these moves follow a broader industry trend of aggressive API pricing as companies compete for developer adoption. Lower prices can expand usage and addressable market, but they also compress near-term revenue per token, a tension that feeds directly into the IPO timing equation the CFO referenced.

The combination of a massive long-term infrastructure bet, a stated 2027 IPO target, and ongoing pricing reductions paints a picture of a company spending heavily to build scale ahead of a public offering, while accepting near-term margin pressure to hold market position.
