. Additional investors included ARK Invest, Baillie Gifford, Fidelity, Salesforce Ventures, Tiger Global, and research firm SemiAnalysis, bringing the total investor count to 29 names3

3

. This massive capital infusion comes just 10 months after Crusoe raised $1.38 billion at a $10 billion valuation in October 2025, representing a remarkable tripling of the company's worth1

Modular Data Centers Drive Growth Strategy

The Denver-based AI data center builder is channeling its fresh capital into existing projects and a new generation of modular data centers called Spark1

1

. By manufacturing these AI-optimized data centers at its own facilities, Crusoe can deploy AI computing capacity quickly without requiring large construction workforces1

1

. The company trucks these modular units to sites with available power, cutting construction time from years to weeks3

3

. A plant outside Denver will eventually manufacture up to 1 gigawatt of Spark capacity annually3

3

. Spark units already operate in Reno, Nevada, powered by repurposed electric car batteries and solar panels supplied by Redwood Materials3

3

. Co-founder and CEO Chase Lochmiller explained that serving AI models to users requires far fewer chips than training them, making massive campuses like Abilene "a bit of overkill" for inference workloads3

3

. These smaller centers also help Crusoe sidestep backlash from local communities protesting massive complexes near their neighborhoods1

Massive Contracted Capacity and Revenue Growth

Crusoe reports more than $140 billion in total contracted value and over 6 gigawatts of gross contracted capacity, of which 1 gigawatt is currently operational3

. The company's cloud bookings have increased more than 20 times year-over-year3

. Crusoe's flagship project includes a 1.2-gigawatt AI campus in Abilene, Texas, used by OpenAI for training models like Astra, and a nearby 900-megawatt site for Microsoft1

. The company also signed a $13 billion, five-year cloud contract with quantitative trading firm Jane Street to supply GPUs and AI infrastructure1

1

. Crusoe's managed inference product, launched late last year, has surpassed $100 million in contracted annual recurring revenue, growing from almost no revenue at the start of 2026 to that run rate by summer3

Three-Pronged Business Model Powers Valuation

Crusoe generates revenue through three distinct streams: leasing data center space to customers who bring their own GPUs, renting out its own GPUs, and selling compute power for running AI models through inference1

1

. As Lochmiller told the Wall Street Journal, "We sell data centres, GPUs and tokens"3

3

. This diversified approach has helped establish Crusoe as one of the most valuable AI infrastructure companies among the emerging "neoclouds" that provide specialized AI cloud and data center services2

2

. The company's Crusoe Cloud platform offers Managed Inference, which uses a software engine called MemoryAlloy to cache frequently reused data, providing up to a fivefold throughput increase for some workloads4

4

. Crusoe Cloud also features Serverless Fine-Tuning, enabling developers to customize open-source AI models using infrastructure that can accommodate petabytes of training data4

Strategic Additions and Future Outlook

Crusoe announced three new independent board members: Cloudflare CFO Thomas Seifert, former Digital Realty CEO Bill Stein, and Redwood Materials founder JB Straubel, who also sits on Tesla's board1

. Straubel, who personally invested in Crusoe in 2021, noted that "grid demand is growing faster than infrastructure can keep up, and that bottleneck is real for AI"3

3

. Founded in 2018 as a crypto mining operation powered by flared natural gas, Crusoe pivoted to AI infrastructure as demand for computing power skyrocketed1

1

. The company now employs more than 1,800 people across five countries and has opened offices in Bellevue and New York3

3

. Crusoe recently met with investment bankers including Goldman Sachs and Morgan Stanley to discuss a potential IPO in the near future1

. Watch for how Crusoe's modular approach reshapes the AI infrastructure landscape and whether competitors can match its rapid deployment capabilities.
