Stargate Michigan Breaks Ground as Component Costs Double Project to $70B+

On June 1, 2026, OpenAI, Oracle, Related Digital, Blackstone, Walbridge, and Michigan Governor Gretchen Whitmer celebrated the official groundbreaking of "The Barn," a 1-gigawatt (GW) data center campus in Saline Township, Michigan. Framed as the single largest economic investment in Michigan's history, the campus represents the first physical buildout of OpenAI's massive "Stargate" U.S. infrastructure program.

However, during a live briefing accompanying the groundbreaking, the project partners dropped a financial bombshell: the Stargate Michigan buildout will require an additional $30 billion to $40 billion in component costs alone, effectively doubling the project's total projected cost to over $70 billion.

This cost escalation comes as OpenAI's capital strategy undergoes significant friction and restructuring ahead of its potential public market debut. OpenAI has recently slashed its long-term future compute spending target by over 57%, trimming it from a projected $1.4 trillion down to a more measured $600 billion. The budget cut reflects growing internal tension; OpenAI's CFO, Sarah Friar, has privately questioned whether the company's revenue can fund future compute contracts in the face of slowing growth and missed internal targets. Meanwhile, rival Anthropic has stepped up the pressure, raising a massive $65 billion Series H funding round at a $965 billion valuation and confidentially filing its draft S-1 prospectus with the SEC for a blockbuster IPO.

The Michigan Buildout and Financing Structure

The physical footprint of "The Barn" campus in Saline Township is massive, consisting of three 550,000-square-foot, single-story, LEED-certified data center buildings. The first building is already nearing completion on the 250-acre site.

The project's financing utilizes a complex capital stack:

  • Equity: Provided by real estate and infrastructure developer Related Digital and funds affiliated with Blackstone.
  • Debt: Fixed-rate, long-term debt financing anchored by PIMCO-managed funds and accounts.
  • Power Supply: DTE Energy is supplying 100% of the project's power using existing resources, augmented by a new battery storage investment financed entirely by the project. This battery backup is projected to generate $300 million in grid savings for DTE's existing customers.
  • Labor: The campus is the first data center in the U.S. built under a project labor agreement executed under the National Maintenance Agreement, covering 14 signatory skilled trade unions, and is the first built under a memorandum of understanding between OpenAI and North America's Building Trades Unions (NABTU). More than 700 union tradespeople are currently on-site, with expectations to create over 2,500 union construction jobs and 450 permanent on-site roles.

Cost Escalation and Internal CFO Friction

The revelation that the Michigan site needs an additional $30 billion to $40 billion for hardware and data center components underscores the brutal economics of frontier AI infrastructure. Sourcing cutting-edge GPUs, advanced liquid cooling, high-throughput networking, and backup power at a 1 GW scale is driving massive component inflation.

While OpenAI CEO Sam Altman continues to push for aggressive, country-scale infrastructure, OpenAI's actual compute commitments are being reigned in. The company's reduction of its long-term compute budget to $600 billion comes as Wall Street and internal finance leaders demand path-to-profitability clarity. During a recent Wall Street Journal conference, OpenAI CFO Sarah Friar acknowledged the intense pressure, describing a "vertical wall of demand" while warning that "There’s not a lot of compute in 2026."

The tension over OpenAI's spending was highlighted in a private exchange between Altman and Altimeter Capital's Brad Gerstner. Gerstner questioned how OpenAI could justify its previous $1.4 trillion in projected compute-related commitments against its current revenue. Altman reportedly responded bluntly: "Brad, if you want to sell your shares, I’ll find you a buyer."
