TSMC Terafab Talks Pressure Intel as Chip Partnership Broadens

Terafab Talks Put Intel and TSMC in Focus

Intel (INTC) shares fell Monday after Elon Musk confirmed that Taiwan Semiconductor Manufacturing (TSM) is discussing a potential role in Terafab, the massive Texas semiconductor project backed by Tesla (TSLA) and SpaceX (SPCX).

Intel joined Terafab in April and was the first chipmaker to publicly support the venture. Musk emphasized that discussions with TSMC remain preliminary and indicated that the company could supplement rather than replace Intel. Even so, the possibility of bringing the world's largest chip foundry into the project was enough to pressure Intel shares while lifting TSMC to an intraday record.

Key Points

• TSMC is in early discussions about participating in Terafab, although Musk said the talks have not produced an agreement.
• Intel shares fell while TSMC reached an intraday record, reflecting different investor reactions to a potentially broader Terafab manufacturing partnership.
• Terafab plans to manufacture chips in Texas for Musk's companies, while Intel remains a named participant in the project.

Why Are TSMC Talks Pressuring Intel?

Intel's market reaction reflects its existing position inside Terafab.

The company joined the project in April, giving Intel Foundry a prominent outside manufacturing relationship as Intel works to expand its contract chipmaking business. Intel's next-generation 14A technology is the only process technology identified for the facility in the supplied reports.

TSMC's potential participation changes that picture. Musk confirmed that discussions are underway after reports that TSMC was exploring ways to help Terafab operate its planned Texas factories.

However, Musk also indicated that TSMC's involvement could complement Intel rather than displace it. No formal agreement with TSMC has been announced, and Intel has not detailed the exact scope of its own role.

The stock market reaction was nevertheless concentrated in Intel. INTC fell roughly 2% in midday trading after a steeper premarket decline, while the broader semiconductor group was comparatively subdued.

That divergence suggests investors were responding primarily to the implications for Intel's Terafab relationship rather than to a broader change in semiconductor sentiment.

Terafab Expands Musk's Semiconductor Ambitions

Terafab is a joint venture between Tesla and SpaceX designed to manufacture chips for Musk's companies in Grimes County, Texas. The project carries an initial investment of $16.8 billion, with total spending across all phases potentially reaching $119 billion.

The planned chips would support applications including Tesla's Optimus robots and Cybercabs as well as SpaceX's planned space-based data centers. Other supplied reports also identify xAI as part of the project's intended customer base.

The scale of those ambitions helps explain why the companies involved in manufacturing Terafab's chips are receiving attention.

Intel was the earliest named chipmaking participant. TSMC would add the world's largest dedicated contract chip manufacturer, which is already expanding its U.S. manufacturing presence and produces chips for major technology companies including Apple (AAPL), Nvidia (NVDA) and Advanced Micro Devices (AMD).

Musk has also engaged with ASML (ASML), the supplier of extreme ultraviolet lithography equipment used by leading semiconductor manufacturers.

The result is a project connecting several parts of the semiconductor supply chain with Musk's growing demand for computing infrastructure.

TSMC Gains as Intel's Foundry Story Faces a New Test

The contrasting price action between TSMC and Intel was one of the clearest market signals from the Terafab news.

TSMC shares climbed to an intraday record after Musk acknowledged the discussions. The company has already benefited from strong demand for advanced semiconductors used in artificial intelligence and is undertaking a major U.S. manufacturing expansion.

Intel's reaction went the other direction because Terafab has served as a visible outside endorsement of its foundry ambitions.

Intel Foundry generated $5.8 billion in total second-quarter revenue according to the supplied reports, but only $293 million came from external customers. The business also recorded a $2.1 billion loss during the quarter.

Terafab is not Intel's only outside relationship. Intel also has a multiyear partnership with Alphabet (GOOGL) involving CPUs and custom chips for Google's AI cloud infrastructure, while Nvidia made a $5 billion investment in Intel last year as part of an agreement to co-develop custom processors.

Terafab itself is still at an early stage, with initial chip production not scheduled until late 2027. The central development Monday was therefore not the loss of Intel's role, but the possibility that Intel may ultimately share the project with another major manufacturer.

What It Means for Investors

Monday's price action separated the Terafab story from the broader semiconductor market.

Intel declined while TSMC advanced, but AMD moved only modestly and semiconductor ETFs were relatively subdued. That points to investor reaction centered on the competitive implications of the Terafab discussions rather than a sector-wide shift.

For Intel, the focus is on the significance of an outside customer for a foundry operation that currently generates most of its revenue internally. Terafab provides Intel with a visible opportunity to demonstrate its manufacturing capabilities to external customers.

For TSMC, the discussions add another possible U.S. manufacturing project to a company already expanding its American footprint. But Musk has described the talks as discussions rather than an agreement.

SpaceX also advanced Monday, although its move included a separate catalyst after Morgan Stanley reiterated its Outperform rating and $300 price target.

The confirmed facts remain limited: Intel is already involved with Terafab, TSMC is discussing a possible role, and Musk has indicated that the two manufacturers could potentially participate alongside one another.

Conclusion

The Terafab story is increasingly becoming about more than a single semiconductor partner.

Intel was the project's first named chipmaking participant, but Musk's confirmation of discussions with TSMC introduced the possibility of a broader manufacturing structure. That prospect pushed TSMC to an intraday record while weighing on Intel shares.

No TSMC agreement has been announced, and Musk has explicitly indicated that its participation could supplement Intel rather than replace it.

For now, the market reaction reflects the significance investors place on major outside manufacturing relationships as Intel attempts to expand its foundry business and TSMC continues building its U.S. presence.
