The race to build AI infrastructure is no longer about cloud compute alone. It is about controlling the entire stack — from the power plants that generate electricity to the data centres that house GPUs to the cloud platform that delivers AI inference to customers. On September 17 2026, Crusoe announced the initial closing of a $3.9 billion Series F at a $30.9 billion post-money valuation — making the Denver-based company one of the most valuable private AI infrastructure companies in the United States.

Who Invested and Why It Signals a Category Shift
The round was co-led by Atreides Management, Mubadala Capital, and Valor Equity Partners. Significant participation came from Founders Fund, GIC, NVIDIA, Qatar Investment Authority, Radical Ventures, and TPG. Additional investors include Altimeter, ARK Invest, Baillie Gifford, Fidelity Management and Research, Polychain Capital, Ribbit Capital, Robinhood Ventures, Salesforce, and more than twenty others.
NVIDIA’s participation is the signal that matters most. When the world’s dominant GPU manufacturer invests in an AI infrastructure company, it is not purely a financial bet. It is a strategic partnership signal — an indication that NVIDIA sees Crusoe as a critical node in the infrastructure network that will deploy its hardware at scale. Gavin Baker of Atreides summarised the investment thesis directly: “As AI grows, the economics flow to the lowest-cost producer of intelligence. Through a vertically-integrated model, Crusoe owns the entire value chain — a structural advantage that compounds as they build.” Read more US AI funding at BestStartup US.
What Crusoe Actually Builds — Power to Compute in One Stack
Crusoe was launched in 2018 as a cryptocurrency business and later pivoted to AI infrastructure. The company now combines power generation and procurement, data centre development, modular infrastructure, and cloud computing within one vertically integrated platform — the only company of its kind at this scale.
The company operates large-scale data centre campuses including a major site in Abilene, Texas used by OpenAI, alongside Crusoe Spark — modular AI factory units that are manufactured for rapid deployment, transportable, and connectable to power sources without large construction crews. This modular approach is specifically designed to ease the local opposition and permitting delays that have slowed large-scale data centre expansion across the United States.
Crusoe now has more than $140 billion in total contracted value, over 6 gigawatts of contracted capacity, with 1 GW already operational. Customers include Meta, Microsoft, Oracle, and Jane Street — which recently signed a $13 billion five-year cloud contract with Crusoe. The company has met with Goldman Sachs and Morgan Stanley to explore a potential IPO. Also read: Profound raises $180M for AI search marketing AEO and GEO and Harvey $550M legal AI September 2026.
