$250 million is the size of the capital raising that Invest Unlisted, the firm built by veteran Australian infrastructure dealmaker Jonathan van Rooyen, has launched to invest in Fleet Data Centres, a US developer that says it wants to build some of the world’s largest data centre campuses. As [the Australian Financial Review’s Street Talk column reported](<https://afr.com/street-talk/veteran-investor-joins-future-fund-pe-to-back-us-s-fleet-data-centres-20261006-p613be>), the vehicle is aimed at Australian wholesale investors who want exposure to the American data centre build-out. The AFR’s account rests on sources “with knowledge of the matter” speaking on condition of anonymity, so the raising has been reported, not announced.
The timing is deliberate. Australian market attention is currently fixed on Firmus, the local AI data centre venture, and Invest Unlisted is positioning its vehicle as the alternative: instead of a single domestic player, exposure to a US developer building campuses across the country.
What Fleet is selling
Fleet Data Centers is the mega-campus development arm of Tract Capital, an alternative asset manager that also assembles prepared development sites. [Its launch materials describe](<https://tractcapital.com/news/tract-capital-introduces-fleet-data-centers-a-new-mega-scale-data-center-development-platform-focused-on-customized-500mw-campuses>) a platform focused on customised campuses of 500 megawatts and up, with combined gigawatt-level capacity, built in collaboration with hyperscale customers and slotted into their existing data centre fleets. Berkshire Partners, a US private equity firm, backs the platform and [carries it in its portfolio](<http://berkshirepartners.com/portfolio-companies/fleet-data-centers>) with the same gigawatt-level language.
The most concrete number attached to Fleet so far is not gigawatts but 230 megawatts: [data centre trade outlet Baxtel reports](<https://baxtel.com/news/fleet-data-centers-raises-4-6bn-for-nevada-data-center-campus>) that Fleet closed $4.6 billion in senior secured notes to fund a 230MW campus in Storey County, Nevada, reportedly fully leased before completion to an unnamed AA-rated tenant with a market capitalisation above $3 trillion on a 197-month (16.4-year) triple-net lease. That works out to $20 million raised per megawatt of capacity — a figure that bundles land, power infrastructure and construction, so it is not directly comparable to headline cost-per-MW build estimates, but it gives the order of magnitude of what hyperscale campuses now cost to finance.
What is measured and what is marketed
It is worth separating the layers of claim here. The gigawatt-level capacity is a target in Fleet’s own launch copy, not a built asset. The 500MW+ campus definition is Fleet’s chosen product spec. What has actually been executed, on the public record, is one 230MW Nevada campus and its $4.6 billion note financing, plus a pre-signed long lease from a single very large tenant. One gigawatt is roughly the output of a large nuclear reactor; Fleet’s marketing is for multiple campuses of that scale. Nothing in the reporting indicates any of the gigawatt figure exists yet outside project pipelines and grid interconnection requests.
For the Australian wholesale investors being pitched, the structure matters more than the megawatts: $250 million in unlisted vehicles is illiquid for years, and the return profile depends on Fleet converting announced ambitions into leased, powered campuses on schedule. The bet is that demand from a handful of trillion-dollar AI tenants keeps absorbing supply at $20 million per megawatt or better. The open question is the one every data centre fund now faces: whether the power connections arrive as fast as the capital.
