In an unexpected turn of events, Intel on Tuesday said that it had joined Elon Musk's TeraFab project. The announcement mentions Intel's ability to develop, produce, and package advanced processors in high volumes, which could help Tesla, SpaceX, and xAI to get enough compute performance for next-generation AI and robotics applications. However, the announcement made in an X post you can expand below does not reveal how exactly Intel will help TeraFab.

The announcement is not accompanied by any press releases or SEC filings, which raises questions about the framework of the collaboration between Intel and TeraFab, as well as any possible legal bindings. In fact, the post in X is deliberately written in a way that barely reveals any concrete details about the structure of the partnership.

Officially, TeraFab is positioned as the "most epic chip-building effort ever" that is to combine "logic, memory and advanced packaging under one roof," which implies localized production in a massive facility. Furthermore, the company is hiring managers to build a greenfield semiconductor fabrication plant in Texas. By contrast, Intel's wording rather implies a virtual semiconductor production ecosystem, or even a consortium that involves chip design, manufacturing, and packaging at Intel and demand from Tesla, SpaceX, and xAI. How such a consortium would differ from a typical wafer supply agreement that large companies tend to have with their suppliers is something that is unclear at this point.
Considering the fact that Elon Musk wants his TeraFab project to ramp up production of chips as soon as possible, a reasonable way to achieve this would be to build a coordinated supply chain with a capacity pool that includes its own facilities as well as facilities belonging to other chipmakers, such as Intel. If we were to speculate further, we would envision custom co-invested fabs or at least product lines that would use unified process technologies, thus offering Elon Musk's companies dual or even triple sourcing to satisfy their demands.
In fact, Tesla, SpaceX, and xAI may even order Intel to develop custom silicon tailored specifically for their workloads, as Intel officially offers custom silicon development services, though this is speculation.
But while the Intel – TeraFab collaboration announcement lacks details on how Elon Musk plans to produce chips that would consume one terawatt of power on an annual basis, the chief executive of Intel expects Elon Musk to reimagine the entire semiconductor industry.
"Elon has a proven track record of reimagining entire industries," Lip-Bu Tan wrote in his own X post. "This is exactly what is needed in semiconductor manufacturing today. Terafab represents a step change in how silicon logic, memory and packaging will get built in the future. Intel is proud to be a partner and work closely with Elon on this highly strategic project."
