A leading Democratic lawmaker has criticized the Trump administration for its stance on federal semiconductor incentive programs, warning that policy uncertainty threatens to worsen an already strained chip supply chain.

The CHIPS and Science Act, signed into law in 2022 under President Joe Biden, allocated approximately $39 billion to incentivize semiconductor manufacturing on US soil. The legislation was designed to reverse a long-term decline: America's share of global chip fabrication had fallen from about 37% in 1990 to roughly 10% by 2022. That growing dependence on foreign foundries—concentrated heavily in Taiwan and South Korea, including industry leaders such as TSMC, Samsung, and SK Hynix—raised alarms among supply chain experts and national security officials, particularly given geopolitical tensions in the Taiwan Strait.

Trump administration officials have criticized the CHIPS Act programs and raised the possibility of discontinuing them. Industry stakeholders pushed back forcefully, noting that companies had committed billions in capital expenditure based on promised federal incentives. Semiconductor fabrication plants require large upfront investments and long construction timelines, making federal funding certainty a key planning factor for manufacturers and their suppliers.

Micron CEO Sanjay Mehrotra said in June 2026 that there is "no line of sight" for AI memory chip supply to meet demand, projecting that shortages would likely extend beyond 2027. Artificial intelligence has become the primary demand driver in the semiconductor market, with hyperscalers including Microsoft, Google, and Amazon acquiring virtually all available chips for training and inference workloads.

The ripple effects extend beyond data centers. During the 2020–2023 global chip shortage—triggered in part by COVID-19 pandemic disruptions—Bitcoin miners faced significant delays in receiving new equipment. Mining rigs rely on specialized application-specific integrated circuit chips, so constraints in semiconductor production can directly affect delivery schedules and equipment pricing. Premiums on mining hardware spiked, squeezing margins for operators unable to secure rigs at reasonable prices.

Mining profitability already operates on thin margins following the April 2024 Bitcoin halving, which reduced block rewards by half. Publicly traded mining companies such as Marathon Digital, Riot Platforms, and CleanSpark have invested heavily in fleet expansion. A return of hardware premiums would make those expansion plans substantially more expensive.

Bipartisan support for addressing semiconductor supply vulnerabilities emerged following the pandemic-era disruptions. The fracturing of that consensus along partisan lines introduces new policy uncertainty into an already complex supply chain landscape, with manufacturers, cloud providers, and crypto miners all exposed to the pace and reliability of future chip capacity additions.
