Crusoe raises $3.9bn to build the five gigawatts it has already sold
Crusoe's Series F values the Denver data centre builder at $30.9bn and pays for capacity customers have already contracted. One gigawatt is running, and the company now makes its own circuit breakers and industrial controls.
The Product Desk
What happened
- Crusoe announced the initial closing of a $3.9bn Series F on 17 September at a $30.9bn post-money valuation, co-led by Atreides Management, Mubadala Capital and Valor Equity Partners.
- The company reports more than $140bn in total contracted value and claims more than 6GW of gross contracted data centre capacity.
- Its flagship is a 1.2GW campus in Abilene, Texas that Oracle will use to host OpenAI workloads, and it is building a 900MW site for Microsoft nearby.
- It builds container-size Spark modules in its own factories and trucks them to sites with spare power, and a plant outside Denver is meant to make up to a gigawatt of Spark capacity a year.
Why it matters
- What it limits constraint With one gigawatt live and five contracted but unbuilt, a customer signing now is buying a queue position, and the delivery date turns on power and electrical gear as much as on GPU allocation.
- Who has to decide decision Crusoe's own pitch sorts buyers by workload: training-scale customers wait for a campus, serving-scale customers take a trucked module next to spare power, and that choice decides whose construction schedule they inherit.
- Who's exposed exposure A sitting director's other company supplies the power system for the modular product, so Spark's delivery promise runs through Redwood Materials.
- What doesn't add up contradiction Lochmiller sells at three layers while, according to the Wall Street Journal, his board has at times pushed to narrow the focus, so a buyer picking a layer cannot assume all three are still funded in two years.

Crusoe's $3.9bn round prices a contract book that runs five gigawatts ahead of deliveryConfirmed2 publishers
A team that needs five megawatts to serve a model is being told by the vendor itself that the flagship campus is the wrong shape for the job. "You don't actually need an Abilene to do that," Chase Lochmiller, Crusoe's co-founder and chief executive, told the Wall Street Journal, and he said running inference from such a site "can be a bit of overkill" [17]. Serving a model to users takes far fewer chips than training one [18]. The product for that buyer is Spark, a container-size module holding graphics cards, storage and cooling, with satellite connectivity built in [5].
What you are buying differs by layer. "We sell data centres, GPUs and tokens," Lochmiller told the Journal [13]. TechCrunch describes the same three layers as leasing space to customers who bring their own GPUs, renting out Crusoe's own GPUs, and selling the compute used to run models [14]. A space lease needs a finished building. Tokens need capacity that is already live on the day you call the API.
Five of the six contracted gigawatts are sold and not yet running [26]. Divide the contracted value by the contracted capacity and each gigawatt carries roughly $23bn [28]. Abilene at 1.2GW plus the 900MW Microsoft site next door account for about 35% of that book [32]. One customer covers a further slice: the $13bn five-year contract with Jane Street that Bloomberg reported is about 9% of the $140bn [10][29].
Crusoe makes many of the electrical components itself, including the industrial controls that coordinate the flow of electricity, the circuit breakers, and the enclosures that keep dust and water off the gear [16]. The published accounts do not include a lead time or a unit cost for those parts [27]. JB Straubel, one of the three new independent directors, said "Grid demand is growing faster than infrastructure can keep up, and that bottleneck is real for AI" [22]. Redwood Materials, which Straubel runs, supplies the microgrid of solar and repurposed EV batteries that powers Spark units, and Crusoe became the first customer of Redwood's energy storage business [21][8]. Units already run in Reno, Nevada, on old electric car batteries and solar panels [20].
Managed Inference launched late last year and has passed $100m in contracted annual recurring revenue, going from almost no revenue at the start of 2026 to that run rate by the summer, Lochmiller told the Journal [15]. Set against the contracted book, that is about 0.07% [31]. Cloud bookings are up more than 20 times year on year [11].
Crusoe raised $1.38bn at a $10bn valuation last October, so the price has roughly tripled in ten months [24][30]. Nvidia, Founders Fund, GIC, the Qatar Investment Authority, Radical Ventures and TPG took part in the new round [2]. Axios reported last month that the company had met bankers including Goldman Sachs and Morgan Stanley about a possible IPO, and Cloudflare's chief financial officer Thomas Seifert will chair Crusoe's audit committee [23][9].
For anyone signing this quarter, the useful split is between the gigawatt that is operational and the five that are not, and where the contract's start date falls. The second split is the layer. A space lease puts you behind Crusoe's construction schedule and its own breaker line; renting GPUs puts you behind hardware supply; buying inference only asks whether capacity is live. If the answer is Spark, the power at the point of use comes from Redwood's microgrid of solar and second-life batteries [21].
What to watch
- Whether the Denver plant's planned gigawatt a year of Spark output turns up as operational megawatts rather than contracted ones.
- An IPO filing would put the $140bn contracted value and the 6GW book under audited disclosure.
- Whether Managed Inference keeps compounding past $100m once the year-on-year cloud bookings comparison stops lapping a near-zero base.
