The deal is off

Crusoe, the Denver-based AI data center heavyweight that just secured a massive $3.9 billion in funding, is hitting the brakes on a major energy partnership. They’ve officially walked away from a $1.25 billion agreement to buy 29 “Superpower” turbines from Boom Supersonic.

If that sounds like a random combo, here’s the tea: Boom Supersonic, which is building a passenger jet called Overture, wanted to repurpose the tech behind its jet engine—the Symphony—into stationary power plants for data centers. Crusoe was meant to be the launch customer, with deliveries originally slated for 2027.

Why it’s giving 'it's not you, it's me'

Boom Supersonic CEO Blake Scholl took to X on Friday to confirm the split. He explained that turbines just aren't in Crusoe’s “near term primary power mix” for their campuses right now. Basically, Crusoe’s energy needs changed, and the launch partnership stopped making sense.

Crusoe’s spokesperson, Andrew Schmitt, confirmed the pivot, noting that the company prefers to stay flexible with its energy sourcing—juggling wind, solar, batteries, and the grid depending on the site. While Crusoe is currently building a 900-megawatt data center for Microsoft that will use on-site gas turbines, they’re clearly not locked into the Boom gear.

Why it matters

This is a lowkey L for Boom Supersonic, which raised $300 million last year specifically to kickstart this power plant side-hustle. The strategy was to use profits from these turbines to help fund their Overture jet development. Scholl claims Boom still has other customers in the pipeline, aiming for 250MW of deliveries next year, but losing their flagship partner definitely stings. For the rest of us, it’s a reminder that even in the high-stakes world of AI infrastructure, the plot thickens and business plans shift faster than a jet at Mach speed.
