TSMC may invest more than $265 billion in its US expansion, with six additional factories potentially slated for Dallas, according to a report from eTeknix.

The figure, if confirmed, would mark a dramatic escalation of the world's largest contract chipmaker's American footprint. TSMC has already committed $65 billion to its Arizona site, where it is building multiple fabs. A $265 billion program would more than quadruple that commitment.

The report names Dallas as the potential location for six new factories. Locating capacity in Texas would diversify TSMC's US manufacturing base beyond Arizona, adding a second geographic pillar for advanced-node production on American soil.

The word "could" carries weight here. The $265 billion figure and the six-fab Dallas plan remain unconfirmed by TSMC; they reflect reporting rather than an announced capital budget. TSMC's board approves capex in stages, and expansion plans have historically shifted with demand signals, incentives, and customer commitments.

Even as a possibility, the scale changes the conversation. A six-fab cluster represents the kind of concentration of advanced manufacturing capacity that typically takes a decade or more to build out, involving thousands of tools, tens of thousands of workers, and an ecosystem of materials and gases suppliers that must co-locate to be viable.

The context matters. Washington has pushed hard to reshore leading-edge semiconductor manufacturing, using subsidies and tariff pressure to pull fabs onto US soil. TSMC's Arizona project already benefited from CHIPS Act funding. Any Texas expansion would presumably be shaped by similar incentive negotiations, though the report does not detail the financial terms.

For customers — notably Apple, Nvidia, AMD, and Qualcomm — additional US capacity would deepen the supply of leading-edge wafers outside Taiwan. That matters commercially: it reduces exposure to geopolitical risk in the Taiwan Strait, a factor that increasingly weighs on procurement decisions and even insurance costs across the electronics supply chain.

What remains unknown is which process nodes the Dallas fabs would run. TSMC's Arizona fabs target advanced nodes, and any large-scale Texas site would likely follow suit, but the report does not specify technology or wafer volumes.

Investors should treat the number as directional, not contractual. TSMC's actual 2025 capital budget, customer demand for US-made wafers, and the pace of incentive disbursement will all determine whether the $265 billion materializes in full, in part, or on a different timeline.

If TSMC confirms even a fraction of the reported plan, Dallas would become one of the largest semiconductor manufacturing clusters in North America, and competition for skilled fab workers and construction capacity in Texas would intensify sharply.
