OpenAI's Stargate: $500B AI infrastructure plan, Michigan campus groundbreaking
In brief
- Stargate initiative: OpenAI targets $500B in AI infrastructure over four years, launched January 2025
- Groundbreaking held June 2026 for $16B Stargate campus in Saline Township, Michigan
- $122B funding round in April 2026 pushed OpenAI valuation to $852B
- ChatGPT reached 900M weekly active users and $2B monthly revenue by April 2026
- UK Stargate project paused due to energy costs and regulatory concerns
Funding and valuation surge
OpenAI closed a funding round in April 2026 that raised $122 billion, pushing its valuation to $852 billion. The company reported $2 billion in monthly revenue as of April 2026, alongside 900 million weekly active ChatGPT users. These figures underscore the financial firepower backing Stargate and the scale of demand for OpenAI's services.
Infrastructure partnerships and setbacks
Stargate partners include Oracle, Microsoft, Nvidia, and AMD, creating a coalition of tech and chip makers aligned on the compute buildout. Yet execution faces real constraints. OpenAI paused its UK Stargate project, citing energy costs and regulatory concerns. The pause affects plans that had included roughly 31,000 GPUs. Separately, the company stepped back from expansion discussions in Texas.

Broader compute ecosystem shifts
The Stargate buildout extends beyond OpenAI. Core Scientific is planning to lease six data centers to CoreWeave for a projected $10 billion in revenue across a 12-year term. Separately, Bitcoin mining firms are pivoting toward AI data centers due to overlapping infrastructure requirements, signaling how the AI compute wave is reshaping hardware economics across the sector.
The Michigan campus groundbreaking marks a tangible step in a strategy that remains ambitious but increasingly constrained by real-world limits on power, land, and regulatory approval.
