- • Fleet Data Centers closed a $4.6 billion funding round, with Milbank advising on a landmark $3.8 billion high-yield note offering—the largest digital infrastructure debt offering to date.
- • Private equity investment in US data centers surged to $45.70 billion in 2025, representing 72% of total data center investment and the highest annual total in at least five years, reflecting accelerating AI infrastructure demand.
- • Fleet targets a market opportunity in mega-scale data center development where customers increasingly seek alternative delivery models beyond traditional building-block approaches, driven by unpredictable demand forecasts for hyperscale capacity.
Summary
Tract Capital formally introduced Fleet Data Centers on January 8, 2025, establishing a specialized platform designed to develop mega-scale data center campuses tailored to enterprise customers' infrastructure needs. The venture pairs Grant van Rooyen, Tract Capital's CEO and Executive Chairman of Fleet, with Chris Vonderhaar, an industry veteran with decades of experience in digital infrastructure development. Vonderhaar leads operational execution while van Rooyen oversees strategic direction. The leadership team comprises industry veterans previously involved in shaping global digital infrastructure evolution.
Fleet Data Centers closed a $4.6 billion funding round, supported by a $3.8 billion high-yield note offering that Milbank structured—marking the largest digital infrastructure debt capital raise of its kind. The company's strategic focus centers on 500MW+ mega-scale contiguous campuses, with particular emphasis on single-user facilities. This positioning reflects a shift in customer preferences: as artificial intelligence and hyperscale cloud computing demand intensify, enterprises increasingly seek customized, long-term capacity solutions rather than modular facilities, particularly given volatile demand forecasts.
The timing aligns with record private equity activity in US data center infrastructure. PE investments in the sector reached $45.70 billion in 2025—the highest annual figure in at least five years and representing 72% of all data center investment capital. Private equity has deployed nearly $200 billion since 2022 on data center projects broadly. This surge underscores sustained institutional capital appetite for digital infrastructure as AI-driven computational demand reshapes investment priorities across alternative asset managers.
Fleet's operational thesis emphasizes predictable, flexible delivery at unprecedented scale. Van Rooyen stated the company is "focused on meeting the capacity and scale needs of tomorrow," positioning mega-scale campus development as a logical response to customers navigating divergent capacity forecasts. The platform's market entry occurs as hyperscale operators and their financial sponsors compete for premium sites and development expertise to meet near-term AI infrastructure requirements.
