Crusoe, a Denver-based AI data center startup that recently raised $3.9 billion, has ended plans to use a new line of stationary power plants developed by fellow Denver company Boom Supersonic.

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, including a massive campus in Abilene, Texas, that supplies computing power to OpenAI.

Boom Supersonic, which is developing a supersonic passenger jet called Overture, launched a new business last year to sell a version of the engine it’s developing for that jet as natural gas-fired stationary power plants. Its Superpower turbine shares about 80% of the same parts with that airborne engine, called Symphony.

Crusoe had signed on to be the first customer for this business, agreeing to spend $1.25 billion on 29 of Boom’s 42-megawatt Superpower turbines. The first deliveries were supposed to begin in 2027. But that deal has since fallen apart, according to Boom Supersonic CEO Blake Scholl.

Friday, in a post on X, after congratulating Crusoe founders Cully Cavness and Chase Lochmiller on the company’s recent raise, Scholl said the companies are no longer moving forward with the turbine launch partnership. Although he did note that other customers were in its pipeline.

“The TL/DR is that turbines are no longer part of Crusoe’s near term primary power mix at Abilene/etc., so a launch partnership just didn’t make sense,” he wrote in the post. “Boom will be delivering about 250MW of Superpowers next year to other sites, and we’re targeting 1GW in 2028. We’re grateful for the help Crusoe gave us in shaping Superpower and continue cheering for their successes. The future is long, and we look forward to potentially teaming up if/when turbines become part of their primary power mix.”

Crusoe confirmed to TechCrunch that it is no longer doing business with Boom.

“We build AI factories from the power up, and we’re bringing new campuses online across the country, powered by innovative energy sources,” spokesperson Andrew Schmitt said in an email. “As our portfolio grows, we stay flexible, choosing the energy solutions that are right for each site as its needs evolve – including turbines, along with wind, solar, batteries and the grid. While Boom has been a great partner, the partnership isn’t the right fit today. We wish them well.”

Crusoe’s initial 1.2 gigawatt data center in Abilene that was built for Oracle and OpenAI is powered by the grid, according to the company. There is also a gas-turbine power plant that is used for backup power only. Crusoe is also building a 900 megawatt data center in Abilene for Microsoft, which will be powered on-site gas turbines.

Losing its launch customer is seemingly a setback for Boom, which raised $300 million last year, largely to commercialize the new business. The idea, Scholl told TechCrunch at the time, was to use profits from the stationary power plant business to fund the development of Overture.

Scholl could not be reached for comment before publication; TechCrunch will update this article if he responds.

 The All Progressives Congress (APC) governorship candidate in Ogun State, Senator Olamilekan Adeola, popularly known as Yayi, has vowed to aggressively pursue and recover corporate taxes and revenue generated by industrial entities operating within the state but remitting their top-level executives’ taxes to Lagos State.

Adeola, who currently represents Ogun West Senatorial District, made the declaration during an interactive session with journalists at the Ogun State Council of the Nigeria Union of Journalists (NUJ) Secretariat in Abeokuta, as he outlined his political agenda for the 2027 governorship election.

Addressing newsmen on his economic strategy on Friday, the lawmaker expressed concern that despite Ogun State being recognised as Nigeria’s primary industrial hub, its internally generated revenue (IGR) fails to reflect its extensive industrial base due to structural tax leakages.

He attributed the disparity to the location of corporate headquarters, where manufacturing plants and operations are based in Ogun State while corporate headquarters, along with high-earning directors and senior managers, remain situated in Lagos.

“Many of these industries establish themselves in our state but take their head offices to Lagos. By doing so, the return on investment from establishing in my state cannot be compared with what it should be, because the top echelon, all the managers and directors are in Lagos, and their taxes are paid to Lagos,” Adeola said.

Comparing the fiscal metrics between both states, the senator noted that Lagos achieved a ₦1.6 trillion revenue benchmark while Ogun State continues to lag behind, estimating that over 30 per cent of Lagos’ corporate tax yields originate from economic activities anchored in Ogun State.

He insisted that his administration would no longer rely on traditional, delayed inter-state monthly tax reconciliation processes for cross-border workers, demanding instead that corporate entities set up regional executive offices within a newly designated Central Business District in Abeokuta.

“I am not saying you should take your head office out of Lagos, but in my new Central Business District here in Abeokuta, come and establish your regional office so that I can have some of your managers and even an Executive Director here. I strongly feel that more than 30 percent of that revenue from Lagos is my money, and I have to collect it,” he stated.

Beyond corporate income tax collection, Adeola also pledged to clamp down on uncoordinated federal mining activities within Ogun, asserting that external commercial operators frequently extract the state’s solid mineral resources using federal permits without direct financial equity flowing to the state government.

On employment and local labour laws, the candidate criticised major industrial complexes for relying on non-resident labour forces and casual positions for indigenous workers, promising to institute a mandatory local content policy requiring firms to offer first right of refusal and managerial quotas to qualified Ogun residents.
