Musk confirms preliminary TSMC talks on Texas Terafab

Elon Musk confirmed preliminary discussions between TSMC and the Terafab project, the Texas chipmaking initiative involving Tesla and SpaceX. The evidence reviewed does not establish a signed agreement or any commitment by TSMC to build, own or operate a factory.

A TSMC role could bring semiconductor manufacturing expertise to a project intended to produce compute hardware for Musk’s companies. Reporting has identified Tesla, SpaceX and xAI as possible customers, but neither that customer set nor any exclusivity has been contractually established. What is confirmed is that talks are taking place. The reviewed sources disclose no investment amount, ownership structure, production technology or project-specific timetable.

Musk described the contact as discussions that might lead to something. Multiple reports reproduced his public reply, but the original post was unavailable in the research environment. The reviewed evidence includes no on-record TSMC statement confirming these talks or a role in Terafab, leaving the company’s decision status and any prospective legal counterparty unresolved.

Terafab was announced before the TSMC discussions. A June SpaceX prospectus describes it as a manufacturing initiative with Tesla and says Intel had joined. SpaceX said the project is intended to extend the companies’ vertical integration into chip design and manufacturing, ease potential future chip shortages, improve compute performance and potentially lower compute costs. The document sets a goal of producing one terawatt of compute hardware per year. That is a company target, not demonstrated capacity. DataPhoenix’s coverage of Meta’s planned 2027 MTIA chip deployments provides related context on another custom AI-chip program involving TSMC.

The manufacturing schedule remains open. In an April earnings call, TSMC Chairman and CEO C.C. Wei said a new fab generally takes two to three years to build and another one to two years to ramp. He was describing typical industry lead times, not announcing a schedule for Terafab.

SpaceX’s prospectus says Intel had joined the initiative. The available evidence does not show whether prospective TSMC involvement would supplement, replace or otherwise change Intel’s role.
