US semiconductor fabrication investment is projected to dramatically outpace China, Taiwan, and South Korea starting in 2027, according to new industry analysis. Driven by unprecedented artificial intelligence demand and supportive US policies, investments will surge from $21 billion in 2025 to $43 billion by 2028, representing one of the most significant shifts in global semiconductor manufacturing in decades.
US Chip Fab Investment Projections and Global Impact
The Semiconductor Equipment and Materials International (SEMI) organization forecasts that US chip fabrication investment will grow at nearly twice the rate of other major semiconductor manufacturing regions. This acceleration comes as companies race to build capacity for AI chips and advanced processors, with the US share of global semiconductor manufacturing investment expected to increase from approximately 15% to over 25% during this period.
Industry experts like Tyler Johnson have noted that this investment surge represents a “fundamental restructuring of global semiconductor supply chains.” The projections indicate that by 2028, the United States will have closed the substantial investment gap with traditional semiconductor manufacturing leaders Taiwan and South Korea, while significantly widening its lead over China.
AI Demand Driving Semiconductor Manufacturing Expansion
The unprecedented growth in artificial intelligence applications has created massive demand for specialized processors that can handle complex machine learning workloads. From data centers to edge computing devices, the need for AI-optimized chips has triggered what industry leaders describe as the largest semiconductor capacity expansion in history.
As noted by analyst Brad Carson, “The AI revolution is fundamentally a semiconductor story. Without massive increases in fabrication capacity, the promised advances in artificial intelligence simply cannot be delivered.” This sentiment is echoed across the industry, with companies from startups to tech giants scrambling to secure manufacturing capacity for their AI chip designs.
US Policy Support for Semiconductor Manufacturing
The CHIPS and Science Act has emerged as a critical catalyst for the projected investment surge. With over $52 billion in funding for domestic semiconductor research, development, and manufacturing, the legislation has created favorable conditions for both established chipmakers and emerging players to expand their US manufacturing footprint.
Policy experts like Jason Kwon have highlighted how “strategic government support has fundamentally changed the economics of semiconductor manufacturing in the United States.” The combination of direct funding, tax incentives, and research partnerships has made domestic chip fabrication increasingly attractive compared to traditional manufacturing hubs in Asia.
Global Semiconductor Manufacturing Landscape Shifts
The projected investment surge represents a significant rebalancing of global semiconductor manufacturing capacity. For decades, Taiwan, South Korea, and China have dominated semiconductor fabrication investment, but the combination of AI demand and strategic policy interventions is rapidly changing this dynamic.
- Taiwan: While maintaining leadership in advanced process nodes, investment growth is slowing due to geopolitical considerations and capacity constraints
- South Korea: Major manufacturers continue significant investments but face increasing competition in memory and foundry segments
- China: Despite ambitious domestic production goals, export controls and technology restrictions are limiting access to advanced manufacturing equipment
Industry Reactions and Expert Perspectives
The semiconductor industry has responded with both optimism and caution to the projected investment surge. While acknowledging the positive impact of increased domestic manufacturing capacity, some experts have raised concerns about potential oversupply and the challenges of rapidly scaling advanced semiconductor production.
As Joshua Achiam noted in his recent analysis, “There’s quite a lot more to the story than this,” highlighting the complex interplay between commercial interests, policy objectives, and technological capabilities. His perspective underscores how semiconductor manufacturing expansion involves multiple stakeholders with sometimes competing priorities.

Future Outlook for Semiconductor Manufacturing
The projected investment surge through 2028 represents just the beginning of a longer-term transformation in global semiconductor manufacturing. Industry leaders anticipate that AI demand will continue to drive capacity expansion well into the next decade, with the United States positioned to capture an increasingly large share of advanced semiconductor production.
As the industry navigates this period of rapid change, the ability to effectively thread together technological innovation, manufacturing expertise, and strategic policy support will determine which regions emerge as long-term leaders in the semiconductor industry. The coming years will test whether current investment projections translate into sustainable competitive advantages in this critically important sector.
