TeraFab: Elon Musk Bets Up to $119 Billion on Mega Chip Factory

According to documents that emerged during some public hearings in Grimes County, the first phase of the TeraFab project—the integrated semiconductor manufacturing facility dedicated to SpaceX, xAI, and Tesla, envisioned by Elon Musk—could require about $55 billion. This already substantial figure could, however, rise to $119 billion if the project is completed in its entirety.

The TeraFab initiative—for which SpaceX has requested local tax incentives—stems from the growing necessity to ensure sufficient production capacity to support the development of AI models, high-performance computing infrastructures, satellites, and autonomous driving systems. The increasing difficulty in obtaining production capacity at TSMC, where giants like NVIDIA and Apple book production line availability years in advance, has compelled Musk to pursue a long-term strategy aimed at reducing dependence on external suppliers and shielding against potential geopolitical risks related to the global supply chain.

The stated goal of TeraFab is ambitious: to concentrate a large part of the semiconductor production supply chain under one roof. The site is expected to include not only chip manufacturing but also memory production, advanced packaging, testing, and even the creation of lithographic masks. This is a radically different approach compared to the current industrial model, where various production stages are distributed among different companies and facilities.

According to Musk, this vertical integration would significantly accelerate development cycles, reducing the time needed between design, production, and validation of chips. This strategy is particularly important in a context where the demand for AI accelerators and specialized hardware continues to grow rapidly.

The project involves the participation of Intel, which has already confirmed its involvement in producing high-performance chips utilizing the 14A production process. Tesla is expected to become one of the first major customers of Intel's production technology within the TeraFab project. For Intel, this is an important strategic agreement, considering that the company's Foundry division is looking to expand beyond in-house production.

Nevertheless, the realization of TeraFab remains an extremely complex operation. Building a modern semiconductor factory requires not only enormous capital but also access to highly specialized machinery and technologies provided by companies like ASML, Lam Research, KLA, and Tokyo Electron. Major equipment for advanced production processes is generally ordered years in advance by large manufacturers like TSMC, Samsung, and Intel, making it difficult to rapidly construct a new supply chain.

Musk has also discussed the creation of a research facility on the campus of the Gigafactory in Texas, with an estimated cost of around $3 billion and a production capacity limited to a few thousand wafers per month. This facility is expected to represent the first operational step towards the broader TeraFab project.
