SpaceX is building a semiconductor fabrication plant called Terafab that will power its operations through natural gas plants rather than Tesla solar infrastructure, TechCrunch reports.

The facility will manufacture chips specifically for data center applications serving SpaceX and xAI, the artificial intelligence company backed by Elon Musk. This move signals SpaceX's intent to vertically integrate chip production for its rapidly expanding AI and computing infrastructure needs.

The choice of natural gas over renewable energy sources marks a departure from Tesla's typical sustainability positioning. Natural gas plants offer reliable baseload power, critical for continuous semiconductor manufacturing operations that demand consistent electricity supply. Data center chips require zero tolerance for power interruptions during production, making grid reliability paramount over renewable idealism.

Terafab enters a crowded landscape where Intel, Samsung, and TSMC dominate advanced chip fabrication. Nvidia has pursued similar vertical integration plays to secure supplies of custom silicon. SpaceX's move reflects broader industry trends where companies reduce reliance on third-party foundries amid global chip shortages and geopolitical tensions around semiconductor supply chains.

The xAI angle adds urgency. Musk's AI venture requires massive computational horsepower, and custom chips optimized for specific workloads deliver performance advantages over off-the-shelf processors. By controlling fabrication in-house, xAI gains leverage over its AI model training and deployment costs.

SpaceX has demonstrated manufacturing ambition before, building Starship rockets and Starlink satellites internally. Semiconductor fabrication represents a different challenge entirely. Fabs require extraordinary capital expenditure, precision engineering, and expertise in photolithography processes. Whether SpaceX can execute competently here remains an open question.

The natural gas decision pragmatically prioritizes operational reliability over brand consistency. Data center chips cannot tolerate power fluctuations. Until battery storage and solar capacity scale
