SpaceX (SPCX), $119 Billion Semiconductor Bet...Will Space Data Centers Work?

SpaceX (SPCX) is expanding beyond a rocket company into the semiconductor business for space AI data centers, adding another high-risk growth narrative to its enterprise value exceeding $2 trillion.

According to a Motley Fool article published on Nasdaq on July 3 (local time), SpaceX, which was a privately held rocket company just six months ago, is now valued as a publicly traded company with a market capitalization exceeding $2 trillion. Elon Musk unveiled Terafab in March 2026. Terafab is a large-scale semiconductor manufacturing project being pursued with Tesla (TSLA) and xAI, and Intel (INTC) later joined to provide manufacturing technology.

Terafab is envisioned to start with a prototype factory in Austin and expand into a larger integrated production facility in Texas. Intel has agreed to provide process technology, including the next-generation 14A manufacturing process, for the full-scale production factory. SpaceX's proposed initial investment is approximately $55 billion, with total construction costs reaching up to $119 billion.

The core is not semiconductors for terrestrial use, but chips for space AI data centers. Musk stated that a significant portion of Terafab's production will go towards orbital AI data center chips. The idea is that in space, abundant solar power can be utilized for electricity, and cooling might also be easier. However, the article points out that this business is just a disclosed plan and has not yet generated revenue, describing it as an unproven, large-scale capital-intensive project in its early stages.

From the perspective of SpaceX shareholders, the current core business remains Starlink and launch operations. According to IPO-related disclosures, the connectivity segment, centered on Starlink, accounted for approximately 61% of revenue in 2025, with revenue of $11.4 billion. Starlink subscribers exceeded 10 million as of March 31. The article evaluates Starlink as a cash cow generating high-margin recurring revenue, supporting more speculative ventures like Starship and xAI.

Terafab's rationale aligns with SpaceX's existing strengths. If space-based computing becomes a reality, SpaceX could put hardware into orbit, Starlink could transfer data, and Terafab could supply the semiconductor brains, creating an integrated structure. However, the article suggests that it could take years for Terafab to generate its first dollar of chip revenue, and the $119 billion project also competes with funding for Starship and Starlink expansion. Given that significant expectations are already reflected in the stock price exceeding $2 trillion, Terafab is judged to be more of a long-term option than an immediate reason to buy.

[Article Key Summary]

-SpaceX is pursuing the Terafab semiconductor project for space AI data centers with Tesla, xAI, and Intel.

-Terafab's initial investment is approximately $55 billion, with total construction costs estimated up to $119 billion.

-The article evaluates Starlink as the current revenue base, but Terafab as a long-term option with no revenue yet.
