  • Shift: SpaceX's own filing states the binding AI constraints are physical — chip manufacturing, data center infrastructure, and power generation. xAI runs ~1.0 GW (Colossus + Colossus II), ~320k+ NVIDIA GPUs, AI capex $12.7B FY25 + $7.7B Q1'26, powered by on-site natural-gas turbines (with Southaven permitting litigation) and ~$3.7B of turbine purchase agreements.
  • Effect on thesis: Primary-source, demand-side confirmation of the watts-per-rack / generation-side thesis. xAI is a top-tier marginal buyer of both GPUs and gas-turbine generation; the Terafab (Tesla+Intel) initiative signals an attempt to escape pure NVIDIA dependence (silicon-capture sub-thesis).
  • Per-ticker: GEV ↑ (gas-turbine demand proxy; identify the ~$3.7B turbine suppliers). NVDA ↑ (xAI ~320k GPU buyer) but TERAFAB/INTC/TSLA = future in-house-silicon risk to merchant GPU. SPCX = the disclosure vehicle.
