Taiwan Semiconductor Manufacturing Company has confirmed it is in discussions with SpaceX over the latter’s proposed Terafab chip plant, but the two sides remain at an impasse over who would operate the facility. According to TSMC CEO C.C. Wei, the foundry will only participate if it retains full operational control, a condition that directly contradicts Elon Musk’s public declaration that SpaceX intends to build and run the plant, with TSMC potentially subleasing space. This standoff highlights the tension between TSMC’s drive to expand U.S. capacity and its commitment to quality standards that have made it the world’s leading manufacturer of advanced AI chips.
TSMC’s U.S. Push and the Margin Math
TSMC is under pressure to grow its presence on American soil. CEO C.C. Wei stated on the company’s third-quarter earnings call that most of its large customers are based in the United States, and they are requesting increased capacity. To that end, TSMC has sent teams to Texas to evaluate sites. The financial imperative is clear: third-quarter 2026 revenue rose to $46.72 billion, with a gross margin of 66.4 percent. However, management warned that overseas fabs are projected to reduce the company’s gross margin by three to four percentage points over the coming years. Capex guidance for 2026 remains between $60 billion and $64 billion. Wei emphasized that TSMC has “no intention to leave food on the table for others,” indicating the company is eager to capture every available dollar of demand, even as expanding beyond its home market carries a cost to profitability.
SpaceX’s AI Chip Hunger
SpaceX’s need for advanced semiconductors is growing in tandem with its AI ambitions. In the second quarter of 2026, the company’s AI segment revenue surged 247 percent to $2.56 billion. Of its total capex of $18.37 billion, $15.83 billion was funneled into AI computing. Musk has previously stated that the company’s understanding with Nvidia is that it will receive a very small percentage of their GPUs next year. This voracious appetite for compute power places SpaceX in direct competition with other AI giants for the limited supply of advanced chips, a supply chain where TSMC holds a near-monopoly on manufacturing. The Terafab project is seen as a way to secure a dedicated source of hardware, but Musk’s desire to operate the facility himself clashes with TSMC’s insistence on running the show.
The Monopoly and the Next Node
TSMC’s position at the top of the semiconductor food chain is underpinned by its manufacturing capability. The foundry produces the advanced AI chips that power companies like Nvidia, and none of its competitors can match its scale or capabilities. This dominance gives TSMC significant pricing power; its gross margins have risen from 59.5 percent to 66.4 percent over the last year. On the technology front, TSMC is researching CFET transistor architecture, a stacking method that could advance chip miniaturization beyond the 2nm node. The company, along with Samsung and Intel, has demonstrated the feasibility of this architecture, which promises to pack more logic into the same wafer area. As TSMC scales its U.S. footprint and navigates client-led fab models, the technical and commercial stakes of who controls the production line will only intensify.
TSMC’s Quality Guardrails and the Margin Trade-off
TSMC’s insistence on operational control stems from a rigorous commitment to yield rates and process maturity that have defined its market leadership. According to CEO C.C. Wei, the foundry’s overseas expansions inherently carry a penalty to profitability; management projected that international fabs would reduce the company’s gross margin by three to four percentage points over the coming years, even as third-quarter 2026 revenue climbed to $46.72 billion with a 66.4 percent margin. This margin erosion reflects the elevated costs of qualifying new sites, transferring legacy expertise, and maintaining the defect density controls that TSMC’s clients expect. While Wei affirmed that TSMC has “no intention to leave food on the table for others,” the structural reality is that ceding operational authority— as Musk has proposed— would expose the facility to variables outside TSMC’s direct quality governance, potentially undermining the very reliability that underpins its pricing power.
SpaceX’s aggressive AI computing roadmap intensifies the stakes of this governance dispute. In the second quarter of 2026, the company’s AI segment revenue surged 247 percent to $2.56 billion, with $15.83 billion of its $18.37 billion capital expenditure directed toward AI computing infrastructure. Musk has publicly stated that SpaceX intends to “build and run the fab,” positioning TSMC only as a sublessee, a model that directly conflicts with Wei’s declaration that any Texas plant “must be run by TSMC.” The tension reflects a broader industry dynamic: TSMC’s gross margins have expanded from 59.5 percent to 66.4 percent over the last year, a trajectory driven by its monopoly-scale control over advanced node production. For SpaceX, securing a dedicated manufacturing footprint is critical to sustaining its AI growth trajectory, but the company’s desire to override TSMC’s operational standards risks compromising the yield consistency that has made TSMC the indispensable partner for Nvidia and other AI leaders.
The Nvidia Ecosystem Dependence
Taiwan Semiconductor Manufacturing Company’s dominance in the industry is deeply intertwined with its relationship with Nvidia. According to The Motley Fool analysis, while Nvidia designs the chips, TSMC manufactures them, creating a critical dependency where none of TSMC’s competitors can match its scale or capabilities for advanced AI production. This monopoly status grants TSMC significant pricing power, evidenced by gross margins rising from 59.5 percent to 66.4 percent over the last year.
The article notes that switching away from this manufacturing partner would be too costly and time-consuming for companies due to Nvidia’s hardware-software ecosystem, specifically the de facto coding language used in AI development called CUDA. This stronghold in enterprise AI has allowed Nvidia to become the world’s most valuable public company with a market cap of over $5.2 trillion as of market open on October 21, 2026.
TSMC’s gross margin expansion reflects its ability to maintain this go-to option status for top tech giants. The Motley Fool highlights that TSMC’s revenue growth is solid, but its margins are where its pricing power truly shows up, with operating and net profit margins also increasing significantly in the third quarter compared to the previous period.
