Intel (INTC) Partners With SpaceX, Tesla and xAI on Terafab Chip Push

TLDR

• Intel has joined the Terafab project alongside SpaceX, xAI, and Tesla to help develop next-generation silicon fab technology.
• Terafab aims to produce 1 terawatt per year of compute power for AI and robotics applications.
• The chip complex will be built in Austin, Texas, with two advanced factories operated jointly by Tesla and SpaceX.
• Intel stock rose around 2-3% on the news; INTC has gained roughly 38% so far in 2026.
• Elon Musk visited Intel’s facilities this past weekend ahead of the announcement.

Intel confirmed Tuesday it is joining Elon Musk’s Terafab semiconductor project, linking up with SpaceX, xAI, and Tesla in what could be one of the most ambitious chip manufacturing efforts in recent memory.

Musk first unveiled Terafab last month. The plan centers on two advanced chip factories in Austin, Texas — one focused on powering cars and humanoid robots, the other built for AI data centers in space.

Tesla and SpaceX will operate the factories jointly. Musk has made no secret of his desire for greater control over semiconductor supply chains as demand grows across AI, robotics, and space computing.

Intel’s involvement adds a key piece: the company brings established chip design, fabrication, and packaging capabilities that the Musk-led group would otherwise need to build from scratch.

Intel also noted it hosted Musk at its facilities over the weekend, just days before going public with the partnership.

INTC Stock Reaction

Intel stock climbed roughly 2-3% on Tuesday following the news. The stock has already gained around 38% year-to-date in 2026, making it one of the stronger performers in the semiconductor space this year.

Tesla stock moved in the opposite direction, falling close to 2% on the same day.

SpaceX, which filed confidentially for a U.S. IPO last week, is expected to launch its market debut later this year.

Terafab’s Broader Scope

Wedbush analysts have suggested the Terafab facility could be an early step toward an eventual Tesla-SpaceX merger, potentially as soon as next year.

For now, the focus is on getting the Austin facility off the ground. Intel’s entry into the project makes the partnership a more concrete industrial effort rather than a concept announcement.

The Terafab website went live at terafab.ai following the announcements from the companies involved.
