AI data-center builder Crusoe has ended a $1.25 billion agreement to buy 29 stationary gas turbines from Boom Supersonic. Deliveries of the 42-megawatt units were expected to begin in 2027, making Crusoe the launch customer for a power business that Boom hoped would help finance its supersonic passenger jet.

Boom’s Superpower turbine shares about 80% of its parts with the Symphony engine being developed for the Overture aircraft. Boom CEO Blake Scholl said turbines are no longer part of Crusoe’s near-term primary power plan at Abilene and other sites, so the launch partnership no longer made sense. Boom still aims to deliver roughly 250 megawatts to other customers next year and reach one gigawatt in 2028.

Crusoe says it will continue choosing among grid power, gas turbines, wind, solar and batteries for each campus. Its existing 1.2-gigawatt Abilene site for Oracle and OpenAI relies on the grid with gas backup, while a separate 900-megawatt Microsoft project is planned around on-site turbines. The canceled order shows that securing electricity for AI infrastructure remains a site-specific engineering and financing decision, even when headline demand is enormous.
