资本承诺显示了规模与速度：Quanta 宣布投入 $904 million 以扩充 California 与 Tennessee 的 2025+ 产能，而其先前 2018 的资本支出高点约为 $50 million；Foxconn 与 Wistron 也各自申报超过 $1 billion 的美国生产与实验室计划，主要在 Texas；Inventec、Pegatron 与 Compal 也规划了新的 Texas 工厂；而且多家公司表示 2026-2027 的支出将比 2025 更大。TSMC 将 2026 资本支出设为历史新高 $56 billion，并把 Arizona 作为 AI 相关需求的重要配置。政策与市场讯号也强化此趋势：美国原先对台湾威胁的关税由 20% 降至 15%，并与 $250 billion 投资承诺挂钩；PwC Taiwan 对 216 位企业领袖的调查则显示，约 40% 将美国列为其 2025 首选目的地，年增 12 个百分点。
其影响同时具有扩张性与战略性：台湾在 2025 的 GDP 成长为 8.63%（15年来最快），2026 目标为 4.56%，其中包含全球云端资本支出估计带来的 0.52% 提升；官员主张海外设厂是在延伸而非掏空台湾角色。风险叙事仍在，包括美国 AI 基础设施股票的波动，以及供应商向需求端靠近后的集中风险，但需求规模仍然庞大；台湾官员指出今年云端服务商预计投资约 $600 billion，且 TSMC 新增厂房的台湾对海外比例声明约为 3:1。在营运层面，邻近需求地很重要，因为 AI 伺服器更重，液冷物流会提高泄漏与运输风险；在商业层面，全球超过 80% 的 AI 客户在美国，这强化了在地组装与缩短供应链的必要性。
Nvidia’s Taiwan-centered supplier ecosystem is accelerating a historic U.S. buildout as AI demand and geopolitics converge. At a Taipei gathering of 40+ chairmen and CEOs from about 25 mostly Taiwanese partners, Jensen Huang praised execution on GB300 and pointed to Vera Rubin as the next step, while reiterating that AI needs chip fabs, computer plants, and AI data-center factories over the next 10 years. Although Taiwan remains core to Nvidia’s supply chain, more than 1/3 of firms at the event are now pursuing their largest-ever U.S. expansions, marking a clear shift from the Asia- and China-heavy manufacturing pattern that dominated even after 2018 trade frictions.
Capital commitments show the scale and speed: Quanta announced $904 million for California and Tennessee capacity for 2025+, versus roughly $50 million in its prior 2018 capex peak; Foxconn and Wistron each filed plans exceeding $1 billion for U.S. production and labs, mainly in Texas; Inventec, Pegatron, and Compal also planned new Texas factories; and companies signaled even larger 2026-2027 spending than 2025. TSMC set record capex at $56 billion in 2026 with a major Arizona allocation for AI-related demand. Policy and market signals reinforce this trend: U.S. threatened tariffs on Taiwan were reduced from 20% to 15% tied to $250 billion in investment commitments, and PwC Taiwan’s survey of 216 business leaders found about 40% naming the U.S. as their top 2025 destination, up 12 percentage points year over year.
The implications are both expansionary and strategic: Taiwan posted 8.63% GDP growth in 2025 (fastest in 15 years), with a 2026 target of 4.56% including an estimated 0.52% lift from global cloud capex, while officials argue overseas plants extend rather than hollow out Taiwan’s role. Risk narratives persist, including volatility in U.S. AI infrastructure equities and concentration risk as suppliers move closer to demand, but demand math remains large, with Taiwan officials citing roughly $600 billion expected cloud-provider investment this year and a stated Taiwan-to-overseas fab ratio of about 3:1 for TSMC plant additions. Operationally, proximity matters because AI servers are heavier and liquid-cooling logistics raise leakage and transport risks, and commercially more than 80% of global AI customers are in the U.S., strengthening the case for local assembly and shorter supply lines.
