Crusoe Raises $3.9B, Valued at $30.9B for AI Compute
The Series F values the data center operator at $30.9 billion, with Nvidia among the backers — as a $40 million startup pitches a solar-farm alternative.
In short
Crusoe raised $3.9 billion in a Series F at a $30.9 billion valuation, money it will spend on both large fixed data centers and truck-portable modular compute units.
At a glance
- Series F: $3.9 billion raised, $30.9 billion post-money valuation.
- Led by Atreides Management, Mubadala Capital and Valor Equity Partners; Nvidia, Founders Fund, GIC, QIA and TPG also participated.
- Prior round October 2025: $1.38 billion at a $10 billion valuation, so the mark has roughly tripled in eleven months.
- Customers named by TechCrunch: Meta, Microsoft, Oracle and Jane Street; the Jane Street deal runs five years and $13 billion.
- Rune raised $40 million on September 16, 2026 for RELIC modules holding up to 1,024 graphics cards, sited on solar farms.
Crusoe closed a $3.9 billion Series F on September 17, 2026, at a post-money valuation of $30.9 billion, TechCrunch reports. The company intends to fund two things at once: conventional large-scale data centers, and small modular units it calls Spark that arrive by truck.
The valuation math
Eleven months earlier, in October 2025, Crusoe raised $1.38 billion at a $10 billion valuation. Roughly tripling that mark in under a year says less about the company's software than about who has access to electricity. Atreides Management, Mubadala Capital and Valor Equity Partners led the round; Founders Fund, GIC, Nvidia, the Qatar Investment Authority, Radical Ventures and TPG also took part.
Three people joined the board: Cloudflare CFO Thomas Seifert, Bill Stein of Primary Digital Infrastructure, and Redwood Materials founder and CEO JB Straubel.
Why an AI factory arrives on a truck
Spark units are designed to be hauled to places where large amounts of power already exist and stood up without a multi-year construction program. That inverts the normal sequence, in which a site gets picked first and grid capacity negotiated afterward. TechCrunch gives no per-unit power rating and does not say how many Spark units are in service.
From flared gas to rented GPUs
Crusoe started in 2018 burning flared natural gas to mine cryptocurrency, then pointed the same idea — stranded energy, movable compute — at AI instead. Revenue now runs on three lines: leasing data center space, renting GPUs, and selling inference capacity. CEO Chase Lochmiller frames the goal as owning the chain from electrons to tokens.
Named customers include Meta, Microsoft, Oracle and Jane Street, and OpenAI uses the company's Abilene, Texas facility. The Jane Street arrangement is a five-year, $13 billion agreement covering GPUs and infrastructure.
A much smaller bet on the same bottleneck
A day earlier, on September 16, 2026, Rune — legally Liitto Technology Inc. — raised $40 million led by Spark Capital for a module called RELIC that sits on the solar farm itself. Each module holds up to 1,024 graphics cards, and the company says it goes up in about an hour. Its current deployment is at a 200-megawatt solar site in Texas, with wind farms flagged as the next target.
Rune says skipping long-haul transmission and transformers cuts infrastructure cost by 85 percent against a traditional facility, and that workloads can run within weeks rather than years. Those figures come from the company and are not independently verified. Every solar plant is a latent data center, CEO William Layden told SiliconANGLE, arguing that power sits idle while AI labs queue for grid connections.
What neither report discloses
Installed capacity in megawatts is missing for both companies, as is any split of Crusoe's $3.9 billion between fixed campuses and Spark units. Either figure would say more than the headline valuation does. Until they surface, this round measures investor appetite for power-adjacent compute rather than compute actually delivered.
FAQ
How much did Crusoe raise in 2026?
$3.9 billion in a Series F, valuing the company at $30.9 billion. Its October 2025 round was $1.38 billion at a $10 billion valuation.
What is Crusoe's Spark?
A modular compute unit shipped by truck to a site that already has a large power supply, so capacity can be stood up without a full data center build.
Why are data centers moving next to power plants?
Grid interconnection is the slow step. Rune, which raised $40 million, places modules of up to 1,024 graphics cards directly on a 200-megawatt solar farm in Texas to avoid it.
