Taiwanese companies other than TSMC are considering approximately $20 billion of additional investment in the United States, the island’s economy minister says. The projects sit within the broader US-Taiwan agreement covering semiconductors, AI-related electronics and other technology capacity. For Taipei, the harder question is how far that ecosystem can globalize without hollowing out Taiwan’s own industrial base.
The migration of Taiwanese technology manufacturing to the United States is beginning to extend beyond TSMC. Taiwan Economy Minister Kung Ming-hsin said on September 2 that companies from the island are planning roughly $20 billion of additional US investments. Kung did not identify the companies, projects, locations or investment schedules. He did identify the commercial force behind them: demand for AI applications and semiconductor orders is currently exceptionally strong. The $20 billion should therefore be treated as prospective investment rather than money already contractually committed.
The $20 billion sits inside a much larger bargain
The announcement matters principally because of the economic agreement Washington and Taipei reached in January. Taiwan committed to facilitating at least $250 billion of direct investment by Taiwanese companies in US semiconductor, energy, AI-related electronics manufacturing and other technology capacity. Its government also agreed to back as much as another $250 billion of financing through credit guarantees, intended in part to help smaller supply-chain companies establish US operations.
In return, Washington capped tariffs on many Taiwanese imports at 15% and promised preferential treatment, including those affecting semiconductors and semiconductor-manufacturing equipment. The agreement also envisages US industrial parks and clusters designed to accommodate Taiwanese suppliers.
The newly identified $20 billion should consequently not be read automatically as money on top of the earlier $250 billion commitment. It is better understood as evidence that the private investment pipeline behind that agreement is beginning to take shape.
TSMC has already transformed the scale of the US buildout
TSMC remains overwhelmingly the largest component. In July, the foundry added another $100 billion to its US plans, taking its intended Arizona investment to $265 billion. The expansion includes additional manufacturing capacity at 2 nanometers and beyond as well as advanced packaging.
But advanced fabs do not function in isolation. They depend on large networks of materials suppliers, chemical companies, equipment specialists, advanced-packaging providers, power infrastructure, cooling systems and highly specialized services. That second layer is increasingly the target of US industrial policy.
Bill Frauenhofer, the Commerce Department official overseeing semiconductor investment and innovation under the CHIPS program, welcomed Kung’s announcement as strengthening US critical-technology capabilities and creating a more resilient semiconductor and electronics supply chain. For Taiwanese suppliers, the incentive is therefore becoming commercial as well as political. As TSMC, hyperscalers and AI-infrastructure companies commit more capacity in America, being physically close to those customers can become an operational advantage.
Taipei is trying to globalize the supply chain without hollowing out Taiwan
That creates an obvious political tension at home. Washington explicitly describes its policy as reshoring semiconductor manufacturing. Taipei describes the same process through a different formula: keeping industry “rooted in Taiwan” while deploying globally.
President Lai Ching-te has already responded to concerns that US investment could hollow out Taiwan’s technological base. His argument is that the strategy remains sustainable as long as companies retain their R&D centers, most advanced manufacturing and largest production capacity in Taiwan. He has also stressed that the $250 billion commitment reflects voluntary corporate investment decisions rather than state-directed spending. That distinction will increasingly be tested in practice.
The $20 billion disclosed in Taipei does not yet represent a list of identifiable factories. Its importance is what it suggests about the next phase of the US semiconductor strategy: after persuading TSMC to build an unprecedented American manufacturing footprint, Washington is beginning to attract the Taiwanese supplier network required to make those fabs into a genuine industrial ecosystem. If these plans turn into facilities, employees and production capacity, AI’s impact on semiconductor geography will no longer be measured only by TSMC’s fabs in Arizona. It will also be visible in how much of Taiwan’s industrial ecosystem follows them.
