Key Takeaways
- • Private equity investment in U.S. data centers surged to $45.70 billion in 2025, representing 72% of the $63.35 billion total invested in the sector and the highest level in at least five years, driven by AI infrastructure demand.
- • Blackstone announced in April 2026 that it would serve as majority equity investor in the $16 billion Stargate data center campus in Saline Township, Michigan, positioning itself as "the largest investor in AI-related infrastructure in the world" with a $150 billion global portfolio and $160 billion in prospective pipeline development.
- • The Saline Township project, originally announced as a $7 billion investment, expanded to $16 billion in total project value and achieved financing closure despite significant local opposition; the developer Related Digital successfully challenged township rejections through litigation and settlement to commence construction.
- • Michigan is attracting substantial AI infrastructure investment, with 17 total data center sites scoped across the state by decade's end, establishing the region as a critical hub for hyperscale computing capacity expansion tied to OpenAI and Oracle's buildout initiatives.
- • Private equity firms are increasingly participating in data center financing and development behind the scenes, complementing direct investment by major technology companies and creating systemic exposure to operational risks including resource consumption concerns identified in other jurisdictions.
Summary
Private equity capital has emerged as a dominant force in U.S. data center development, with investment reaching $45.70 billion in 2025—the highest level in at least five years and accounting for 72% of all capital deployed in the sector. This surge reflects the massive infrastructure requirements associated with AI model training and deployment, as major technology firms scale hyperscale computing facilities globally.
Blackstone exemplifies the scale and strategic importance of private equity's role in this buildout. During its April 2026 earnings call, CEO Stephen Schwarzman announced that Blackstone had become "the largest investor in AI-related infrastructure in the world," with a current portfolio comprising over $150 billion in data centers globally, including facilities under construction, and an additional $160 billion in prospective pipeline development. The firm's April announcement of its majority equity stake in the $16 billion Stargate data center in Saline Township, Michigan, exemplifies the magnitude of individual transactions driving sector growth.
Michigan has become a focal point for this infrastructure wave, attracting the Stargate project through Related Digital, a private equity-backed developer. Originally announced as a $7 billion investment, the project expanded to $16 billion in total development value, combining equity from Blackstone and other institutional investors with debt financing. The project proceeded despite significant local opposition; the Saline Township board and planning commission both rejected it in September, but Related Digital pursued litigation and ultimately reached a settlement allowing construction to commence by June 1, 2026. Beyond Stargate, the state is targeting 17 data center sites for development across Michigan by the end of the decade, positioning the region as a critical infrastructure hub for OpenAI, Oracle, and other major AI developers.
The expansion of private equity involvement carries operational implications for host communities. In parallel situations, such as Blackstone's QTS facility in Fayetteville, Georgia, data centers have generated significant resource consumption demands, with one facility consuming nearly 30 million gallons of water without initial payment arrangements, highlighting the infrastructure and regulatory complexities these projects introduce to local markets.
