Key takeaways:
- Musk confirmed TSMC is in talks about Terafab, describing them as just discussions. He suggested TSMC chips would likely supplement Intel’s rather than replace them.
- Intel is the only named manufacturing partner at Terafab, which makes the project its most visible outside foundry win.
- A TSMC-owned and -operated plant at Terafab would turn that exclusive role into a shared one.
- Intel’s foundry division earns little from outside customers, so its high valuation leans on future wins.
- Watch for a formal TSMC deal and Intel’s 14A design kit release this month.
Why a few words from Musk can move a $600 billion chipmaker: Intel and the Terafab test
Intel shares fell on Monday after Elon Musk confirmed that Taiwan Semiconductor Manufacturing Co (TSMC) is in talks about joining Terafab, the Texas chip venture backed by Tesla, SpaceX and xAI. Musk called them just discussions, adding that something may come of them, and suggested any chips TSMC makes would likely supplement Intel’s rather than replace them. Intel was down more than 4% before the open and about 2% in morning trade, while TSMC’s US-listed shares rose about 1% and its Taiwan-listed stock closed around 3% higher.
A few words on social media moving a chipmaker worth more than $600 billion can look like an overreaction. It makes more sense once you understand what Terafab represents for Intel, how the contract chipmaking business works, and how much future success is already built into Intel’s share price.
What Terafab is, and why Intel’s role mattered
Terafab was announced in March as a roughly $25 billion chipmaking project in Austin, billed as the largest chip plant ever planned. It aims to start at about 100,000 silicon wafers a month and eventually scale to around 1 million, producing chips for robots, vehicles and space applications. Around $16.8 billion has reportedly been committed to the first phase.
Intel joined in April as the only named manufacturing partner, with its 14A process, its most advanced planned production technology, designated for the facility. For Intel, that made Terafab more than one customer contract. It was the most visible proof that outside companies were willing to bet on Intel’s factories.
Foundries and why customers matter so much
A foundry is a company that manufactures chips designed by others. TSMC is the dominant example: it makes chips for many of the world’s biggest technology companies but does not sell chips under its own brand.
Intel has traditionally designed and built its own processors. Under its current turnaround strategy, it is also trying to become a foundry for outside customers. That is an expensive ambition. Leading-edge fabs cost tens of billions of dollars, and each new generation of manufacturing technology, known as a process node, requires heavy spending before it earns anything.
This is why customers matter so much. A foundry needs enough orders to keep its plants busy, recover its investment and fund the next node. A large, committed customer that fills a new plant from the start is known as an anchor customer. Winning one also signals to other chip designers that a foundry’s technology is good enough to rely on.
The numbers show how early Intel is in that journey. In the second quarter, outside customers generated only about $290 million in revenue for Intel’s foundry division, while the division lost about $2.1 billion overall.
How a TSMC role could change the picture
According to the Culpium newsletter, which first reported TSMC’s interest on Friday, the likely arrangement would see TSMC own and operate the facility, with Terafab acting as the anchor customer. That would mirror TSMC’s joint ventures in Japan and Germany.
That structure matters more than simply sharing orders. If TSMC runs a plant at Terafab, Intel’s role could shift from being the sole manufacturing partner to one of two, competing for capacity at the very project meant to showcase its foundry ambitions. Analysts have warned that if Intel ends up not participating, or becomes just one of several technology providers, investors may rethink the credit they have given the company. Others have suggested TSMC could run a fab dedicated to Tesla, SpaceX and xAI.
Why the share price is so sensitive
Intel’s shares have roughly tripled over the past year, and the stock is reported to trade at about 71 times expected earnings. A multiple that high means investors are paying mainly for profits they expect in the future, not for what the company earns today. Much of that expectation rests on the foundry business winning big outside customers.
When a valuation leans on future wins, news that threatens one of those wins can move the stock even if nothing has been signed. The market is effectively repricing the probability of an outcome, not reacting to a confirmed loss.
The Terafab news also landed on a day when analysts estimated Intel had lost further share of the PC processor market in the third quarter, with rival AMD gaining ground, adding a second source of pressure.
The case against overreading it
Musk described the talks as discussions only, and nothing has been agreed. His comment that TSMC chips would likely supplement Intel’s suggests Terafab’s planned scale could accommodate both. A project of this size could also benefit from having two suppliers, which reduces the risk of relying on any single manufacturer.
What to watch
The key signal is whether TSMC signs a formal agreement, and on what terms. A deal in which TSMC owns and runs its own plant would raise more questions for Intel than one where it supplies a smaller share of chips. Intel’s planned release this month of the design kit for its 14A process, the tools customers need to design chips for that technology, is another test of whether outside companies are ready to commit to Intel’s factories.
