Colossus Went Up in 122 Days. Its Subcontractors Are Still Filing Liens.
Contractor liens past $570 million, a $30 million wrongful-death suit now in federal court and a House demand for a site tour are the arriving bill for the build speed xAI sells as its edge. The 10-gigawatt roadmap runs through paying it.

A first-day fall, and no lifeline to tie to
Alexis Vicent was on his first day at SpaceXAI's Colossus 2 site in Memphis, working through a third-party staffing agency, when he fell 25 to 30 feet off a ledge with no guardrail. He died of his injuries in February. 1
His family's $30 million wrongful-death suit, filed in Shelby County on 11 August and moved to federal court on 11 September, names the xAI affiliates that own the campus. Tennessee OSHA logged the fall as a "Serious" violation: Vicent wore a harness, but with no lifeline there was nothing to tie off to. 1
The 122-day boast is the pitch to investors
The company's own ledger makes it: Colossus went up in 122 days, doubled to 200,000 GPUs in 92 more, with a roadmap to a million. 2 Musk told investors SpaceX will "build exclusively on Nvidia," scaling from over 2 gigawatts by year-end to roughly 10 by late 2027; Slicast reports the August financing behind the push was a $20 billion round. 34
Colossus doubled to 200,000 GPUs in 92 days; the roadmap calls for a million

The bill stayed with the suppliers
Darana Hybrid, the campus electro-mechanical contractor, has filed six liens worth $569.34 million against SpaceXAI affiliates: $136.8 million in Shelby County at the end of July, then $432 million more in DeSoto County on 4 August for the Southaven power plant and a third data center. 5 In late September, Ferguson Enterprises became the ninth contractor to file, claiming $4.2 million in unpaid pipe. 6 The squeeze runs downhill: a subcontractor, Delta Industries, is suing Darana itself over $669,218 in unpaid concrete for Colossus 2. 5
One contractor was paid $1.4 billion; the liens on file now pass $570 million

The other side says it overpaid
SpaceXAI countersued Darana for fraud and "rampant overcharging," alleging it overpaid by $500 million to $800 million on roughly $1.4 billion of work since April 2024. 5 The countersuit's papers show the incentive ran the other way too: three restricted-stock bonuses of $9.5 million each, tied to commissioning 110,000, 220,000 and 330,000 GPUs. 5
The turbines stay until July 2027
The 69 gas turbines that carried the campus ran without the clean-air permits their size requires, and they do not fully come down until July 2027, when a permanent 1.2-gigawatt plant is due. 7 The Justice Department backed the fleet as a matter of "national, economic, and energy security," and a September study found no major pollution increase around Colossus 1, Slicast reports. 74
Representative Frank Pallone, the House Energy and Commerce Committee's top Democrat, wrote on 29 July demanding emissions data, permitting records and a staff tour, for sites near predominantly Black neighborhoods. 89
Who pays for the next 122 days
Musk bought APR Energy, whose mobile plants can be running in 15 to 30 days, in a deal whose filings imply at least $1 billion, aimed, Slicast reports, at the same power gap the turbines were rushed in to fill. 104
No filing states that xAI deliberately stretched supplier payments; the liens and the overcharge figures are allegations in active litigation, not adjudicated debt. If the liens hold, the arithmetic is plain: speed was the strategy, and the suppliers were the lenders. Watch two clocks: whether the Darana claims clear before the next Nvidia generation lands on site, and whether Pallone gets his tour before the turbines come down. 7
