Crusoe raises 3.9 billion dollars at 30.9 billion valuation to build AI factories

Crusoe, the Denver based AI infrastructure company that built the Abilene, Texas data center campus used by OpenAI, said on September 17, 2026 that it had closed the initial tranche of an oversubscribed $3.9 billion Series F funding round at a $30.9 billion post money valuation. The round was co-led by Atreides Management, Mubadala Capital and Valor Equity Partners, with backing from new and existing investors including Founders Fund, GIC, NVIDIA, Qatar Investment Authority (QIA), Radical Ventures and TPG, according to the company.

The eight year old company began in 2018 as a cryptocurrency mining operation powered by flared natural gas, then pivoted to AI infrastructure as demand for computing power surged. It divested its crypto operations and now describes itself as the industry's first vertically integrated AI infrastructure provider, leasing data center space to customers that bring their own GPUs, renting out its own GPUs, and selling compute power used to run AI models, known as inference.

Crusoe's fresh capital will finance existing data center projects, including the large site in Abilene used by OpenAI, as well as smaller modular AI factories that can be transported by truck and connected to large power sources almost anywhere. The company manufactures these modular data centers, called Spark, in its own facilities, which lets it deploy compute capacity quickly without the need for large construction workforces. The smaller units could also help Crusoe sidestep, at least in part, backlash from local communities protesting massive complexes near their neighborhoods.

TechCrunch reported on September 17, 2026 that the round pushes Crusoe's valuation to $30.9 billion and that the company also announced three new board members: Cloudflare CFO Thomas Seifert, Bill Stein, a partner and CIO at Primary Digital Infrastructure, and Redwood Materials founder and CEO JB Straubel, who also sits on Tesla's board. Straubel already had ties to Crusoe: he personally invested in the company in 2021, and Crusoe later became the first customer of Redwood's energy storage business.

Key Facts

Reuters reported on September 17, 2026 that Crusoe secured $3.9 billion in a Series F funding round, reaching a $30.9 billion valuation, and that the round will finance massive data center projects and the truck transportable modular AI factories called Spark. The company reports more than $140 billion in total contracted value, more than 6 gigawatts of gross contracted capacity across data centers and cloud, of which 1 gigawatt is delivered and operational, and cloud bookings up more than 20 times year over year.

Crusoe said its managed inference product, launched late last year, has passed $100 million in contracted annual recurring revenue, going from almost no revenue at the start of 2026 to that run rate by the summer. The company says the product delivers up to 9.9 times faster time to first token and 5 times higher throughput versus vLLM. The Next Web reported on September 17, 2026 that Crusoe called the round oversubscribed and that the list of further investors runs to 29 names, including ARK Invest, Baillie Gifford, Fidelity, Salesforce Ventures, Tiger Global and the research firm SemiAnalysis.

Crusoe said it manufactures Crusoe Spark modular data centers in the United States, shortening data center construction timelines from years to weeks. Customers including Cognition, Figure and Perplexity already run on Crusoe Cloud, while the company's broader customer list includes Meta, Microsoft and Oracle. Crusoe employs more than 1,800 people across five countries and has opened offices in Bellevue, Washington, and New York City.

Data Center Dynamics reported on September 17, 2026 that Crusoe is behind OpenAI's first Stargate campus in Abilene, Texas, and is developing several other data centers across the United States while leasing space from third party providers to host its cloud platform. Alongside Abilene, it is working on a 1.4 gigawatt site in Texas, two sites in Missouri, and natural gas powered data centers in Alberta, Canada. It recently backed off from a project in Cheyenne, Wyoming, and was named as a potential partner for a project in Nebraska.

The company recently signed a $13 billion, five year cloud contract to supply quantitative trading firm Jane Street with GPUs and AI infrastructure, Bloomberg reported. Crusoe recently met with investment bankers, including Goldman Sachs and Morgan Stanley, to discuss a potential IPO in the near future, Axios reported last month. The fresh fundraise comes 10 months after Crusoe raised $1.38 billion at a $10 billion valuation last October.

Analysis

What this really means is that Crusoe has moved from a niche operator of energy intensive crypto sites to a central supplier of the physical layer of the AI boom, and investors are pricing it accordingly. The jump from a $10 billion valuation in October 2025 to $30.9 billion less than a year later is not simply enthusiasm for AI. It reflects a bet that demand for compute will keep outrunning the ability of conventional construction to deliver data centers, and that a company able to build capacity in its own factories and truck it to available power can capture value at several points in the chain at once.

Gavin Baker, managing partner and CIO of Atreides Management, said Crusoe owns the entire value chain, calling that a structural advantage that compounds as the company builds. He added that the economics of AI flow to the lowest cost producer of intelligence. That framing helps explain the round's size. Crusoe is not only leasing space; it manufactures the modular units, operates the cloud, and sells inference, the step where models actually answer users. Serving a model to users needs far fewer chips than training one, and Lochmiller told the Wall Street Journal that you do not actually need an Abilene to do that, which is the core of the Spark pitch.

The bigger picture here is that the capital markets are funding two different visions of AI infrastructure at once. One is the hyperscale campus, of which Abilene is the emblem. The other is distributed, factory built capacity placed wherever electricity is cheap and available. Crusoe is trying to own both, and it argues that its vertical integration keeps costs down while competitors assemble the same layers from separate vendors. Mubadala Capital's Ibrahim Ajami noted the firm has partnered with Crusoe since 2022 and has invested in every round since.

The risks are visible in the same materials. Crusoe's board has at times been unsettled by the strategy and has suggested narrowing the focus, the Wall Street Journal reported, a sign that even insiders worry about spreading across so many regions and businesses. The company has also had to step back from at least one project, in Cheyenne, Wyoming, and local opposition to large complexes is a constraint that the Spark model addresses only partly. Execution at this scale, across five countries and more than 1,800 employees, will be the test.

Why It Matters

The round matters because AI progress is increasingly limited by physical infrastructure rather than by ideas or even chips. Crusoe reports more than $140 billion in total contracted value and more than 6 gigawatts of gross contracted capacity, with 1 gigawatt operational. Those are the kinds of numbers that determine how quickly models can be trained and served. A company that can shorten construction from years to weeks, as Crusoe says Spark does, changes the time horizon for everyone building with AI.

It also matters for the geography of computing. If modular data centers can be trucked to large power sources, then the map of where AI runs becomes more flexible, and communities that have resisted large campuses may see smaller installations instead. The units already running in Reno, Nevada, on old electric car batteries and solar panels show a model in which power and compute are paired locally rather than concentrated in a handful of giant sites.

Finally, the size of the round and the list of participants signal that sovereign wealth funds, established venture firms and strategic investors are willing to concentrate large sums in a single private infrastructure company. With Crusoe reportedly weighing an IPO and holding a $13 billion cloud contract with Jane Street, the company now sits close to the center of the AI supply chain, and its choices about where and how to build will shape the costs that flow to every company renting its capacity.

Next Up

Crusoe says a plant outside Denver will eventually make up to a gigawatt of Spark capacity a year, and the company will use the Series F to scale both its large campuses and its modular units while fueling the growth of Crusoe Cloud. Its expansion list includes the 1.4 gigawatt Texas site, two Missouri sites, and natural gas powered data centers in Alberta, Canada, alongside its existing Abilene campus.

Investors and observers will watch for a potential IPO, following the company's meetings with Goldman Sachs and Morgan Stanley, and for evidence that the modular model can be deployed at the volume Crusoe promises. The company's ability to keep cloud bookings growing, after reporting more than 20 times year over year growth year to date, and to convert its contracted pipeline into operational capacity, will be the measures that matter next.
