SpaceX to Build Turbine Blade Foundry for AI Data Center Power
The gist
AI data centers cannot scale without power, and the supply chain for both grid connections and on-site generation hardware has become a hard ceiling on buildout speed. SpaceX entering turbine blade manufacturing could reduce one specific bottleneck, but the broader infrastructure gap spans transformers, substations, substrates, and memory.

The full picture
Elon Musk announced SpaceX will bring turbine blade and vane casting in-house, a move he said could cut natural gas generator procurement delays by up to 18 months. Turbine blade production currently takes 60 to 90 weeks per batch, and surging AI data center demand has created a supply bottleneck for blades and vanes. Howmet Aerospace, which holds roughly half of the global market share for natural gas turbine components, saw its stock fall more than 7% following the announcement before partially recovering. The broader context is a severe power infrastructure shortage: U.S. electricity grid connection delays are pushing AI data center projects toward portable natural gas turbine generators as an alternative. Bloomberg reported that building private gas generation has tripled in cost in recent years, and power-gear backlogs now run past 2030.
