The Factories Are Built and the Question Is Whether They Can Compete
The CHIPS and Science Act of 2022 and the Inflation Reduction Act of 2022 together committed approximately eight hundred billion dollars of direct subsidies, tax credits, loan guarantees, and grant funding to the domestic US manufacturing of semiconductors, solar panels, EV batteries, and the materials supply chains that these technologies require, representing the largest deliberate industrial policy intervention in the United States since the defence-industrial build-up of the Second World War. The policy rationale was supply chain resilience, whose exposure the COVID-19 semiconductor shortage and the geopolitical vulnerability of Taiwan's concentration of leading-edge chip manufacturing had demonstrated in commercially and nationally costly ways, and the decarbonisation of the US energy and transport system, whose domestic manufacturing scale-up was intended to combine climate objectives with employment and industrial capacity goals. Three years after the legislation's passage, the autumn of 2026 is the period in which the first significant cohort of the manufacturing investments that these policies catalysed are reaching the point where their commercial viability, rather than their policy-supported capital raise, determines their future trajectory, creating what the financial press is calling the reshoring commercial test: whether the factories built with subsidy can produce the products at the quality, cost, and volume that their markets require without the continued subsidy escalation that their initial business cases did not anticipate needing.
The commercial environment in which this test is occurring is shaped by the November 2026 tariff truce expiry, the APEC Leaders' Meeting in Shenzhen on November 18 to 19, and the Xi Jinping state visit's outcomes whose combined implications for US-China trade policy will determine whether the tariff protection that makes domestic US manufacturing economics viable is extended, modified, or disrupted. A tariff truce collapse that allows Chinese semiconductor equipment, solar wafers, and EV battery cells to re-enter the US market at their production cost advantage over US-manufactured alternatives would directly challenge the business cases of the manufacturing investments whose economics are predicated on the current tariff floor. The APEC meeting's potential for tariff framework negotiations and the Busan truce's November expiry create the policy uncertainty that is simultaneously motivating the accelerated commissioning of US manufacturing facilities and creating the investor uncertainty about the business case duration that is reflected in the muted secondary market valuations of the reshoring-dependent equity positions.
TSMC Arizona and the Yield Ramp Challenge
TSMC's semiconductor fabrication facility in Phoenix Arizona, the most commercially significant single manufacturing investment in US industrial history at approximately forty billion dollars of capital investment across two fab phases targeting four-nanometre and two-nanometre process nodes, is at the yield ramp phase in 2026 whose outcome will determine whether the CHIPS Act's semiconductor manufacturing bet achieves its commercial rationale. The yield ramp challenge, in which the proportion of functional chips produced from each silicon wafer increases from the initial production start-up percentage toward the commercial target percentage that makes the fab's economics viable at the planned selling price to the Apple, AMD, and NVIDIA customers whose commitments underpin the fab's revenue model, has proceeded more slowly than the initial CHIPS Act business case assumed. Reports from TSMC's Arizona management team in late 2025 indicated that the Arizona fab's yield rates were tracking below TSMC's equivalent Taiwan facility performance at the same stage of its ramp, with the workforce training gap, supply chain localisation challenges for the specialty chemicals and gases whose Taiwan supply chain TSMC cannot fully replicate in Arizona, and the construction quality of the cleanroom environment identified as the contributing factors. Intel's Ohio fab, the larger and more ambitious domestic semiconductor manufacturing expansion announced in 2022 with forty-four billion dollars of planned investment, has experienced the most significant schedule delay of any major CHIPS Act manufacturing project, with Intel's own financial difficulties and executive restructuring in 2024 and 2025 creating the capital availability and management continuity challenges that have pushed the Ohio fab's first production milestone from its 2025 target to a revised 2027 to 2028 timeline.
The solar manufacturing investment catalysed by the IRA's investment tax credit and the domestic content bonus has created the US solar manufacturing capacity expansion whose twelve months of commercial operation is now providing the first evidence of whether IRA-supported US solar panel production can achieve the cost and quality benchmarks that utility-scale solar project developers require. First Solar's Ohio and Alabama thin-film manufacturing plants, QCells' Georgia facility, and the Hanwha Q CELLS expansion that followed, collectively represent the US solar manufacturing capacity whose production economics, panel efficiency, and supply reliability the utility-scale solar development community is assessing against the Chinese-supplied alternative that the tariff and domestic content incentive structure is designed to make less competitive without being illegal to import. The early commercial evidence is mixed: US-manufactured panels are competitive on reliability and warranty quality with the premium tier of Chinese manufacturers, but the manufacturing cost per watt of US production remains above the leading Chinese producers whose scale advantages at ten to twenty times US production volume create the learning curve efficiency and raw material procurement advantages that the current US manufacturing scale has not overcome despite three years of IRA support.
The EV Battery and the Midterm Policy Risk
The EV battery manufacturing investment, whose approximately one hundred and fifty billion dollars of IRA-catalysed factory announcements from LG Energy Solution, Samsung SDI, SK On, Panasonic, and various domestic battery startups represents the most geographically dispersed reshoring investment across the US Midwest and South, faces the dual commercial test of vehicle manufacturer demand at the production volumes the factories were designed to serve and the tariff policy continuity whose variation with the midterm election outcome creates the uncertainty that the battery factory operators' capital allocation decisions must incorporate. The battery factories whose construction is partially complete and whose first production volumes were delivered to Ford, GM, and Stellantis in 2025 and 2026 are discovering the battery cell cost performance gap whose closure through manufacturing learning curve and raw material procurement scale-up is proceeding more slowly than the optimistic ramps that the IRA grant applications projected.
Top 10 Companies in US Reshoring Manufacturing and Industrial Policy-Dependent Production Globally
- TSMC Arizona: Taiwanese semiconductor company with $40 billion Arizona fab investment at the yield ramp stage; its four-nanometre and two-nanometre process node development and its Apple, AMD, and NVIDIA customer commitments create the reshoring investment whose yield ramp performance is the most commercially watched data point for the CHIPS Act's semiconductor manufacturing commercial test.
- Intel (Ohio Fab): US semiconductor company with delayed $44 billion Ohio fab and restructuring challenges; its CHIPS Act grant and its schedule delay to 2027 to 2028 create the domestic semiconductor company whose manufacturing ambition is the most policy-dependent of the CHIPS Act recipients and whose commercial viability requires both subsidy continuity and competitive process node performance that Intel's technology roadmap must deliver.
