Crusoe, a Denver-based AI data center startup that recently raised $3.9 billion, has ended its partnership with fellow Denver company Boom Supersonic, abandoning plans to purchase $1.25 billion worth of stationary power turbines. The deal, which would have made Crusoe the launch customer for Boom’s new power plant business, called for the delivery of 29 of Boom’s 42-megawatt Superpower turbines, with first deliveries scheduled to begin in 2027.
Founded in 2018 as a bitcoin miner that ran on excess natural gas from oil fields, Crusoe has since become one of the biggest builders of AI data centers. The company built a massive campus in Abilene, Texas, that supplies computing power to OpenAI. Boom Supersonic, known for developing a supersonic passenger jet called Overture, launched its stationary power plant business last year. The Superpower turbine shares about 80% of parts with Symphony, the engine Boom is developing for its aircraft.
Boom Supersonic CEO Blake Scholl confirmed the partnership’s end in a post on X on September 25, 2026, explaining that turbines are no longer part of Crusoe’s near-term primary power mix at Abilene and other sites, making a launch partnership impractical. Despite losing its anchor customer, Scholl indicated that Boom will deliver about 250 megawatts of Superpowers next year to other sites and is targeting 1 gigawatt in 2028. He expressed gratitude for Crusoe’s help in shaping the Superpower product and left open the possibility of future collaboration.
Crusoe confirmed the split to TechCrunch, with spokesperson Andrew Schmitt stating that the company stays flexible in choosing energy solutions for each site as needs evolve, including turbines, wind, solar, batteries, and the grid. He emphasized that while Boom has been a great partner, the partnership isn’t the right fit today. The company’s initial 1.2 gigawatt data center in Abilene, built for Oracle and OpenAI, is powered by the grid, with gas-turbine backup power. Crusoe is also building a 900 megawatt data center in Abilene for Microsoft, which will be powered by on-site gas turbines.
The dissolution of the partnership represents a setback for Boom, which raised $300 million in December 2025, largely to commercialize the stationary power plant business. The company’s strategy was to use profits from selling these turbines to fund the development of its Overture supersonic passenger jet. The loss of Crusoe as a launch customer leaves Boom searching for alternative buyers to meet its ambitious deployment targets, though the company maintains it has other customers in its pipeline for the Superpower turbines.
