The United States designs chips but cannot produce chips effectively.

Judge as of February 2025. True: industry data show US firms lead in chip design while US-based manufacturing of chips, especially advanced logic chips, is small or uncompetitive (e.g. a low share of global capacity, with leading-edge production mostly in Taiwan). Mostly true: this holds for leading-edge chips, but the US still produces a meaningful amount of mature-node or other chips (Intel, TI, GlobalFoundries), so 'can't produce effectively' overstates it slightly. Mixed: US design leadership holds, but US manufacturing is substantial and competitive in several segments. Mostly false: US manufacturing is broadly competitive, and the claim rests only on a narrow leading-edge gap. False: the US is not a leader in design, or US chip production is clearly competitive overall.

Set before the research began.

   “U.S.-headquartered firms lead in chip design and manufacturing equipment, accounting for the highest global revenues in 2021 for chip design (46%), as well as in the production of semiconductor manufacturing equipment (42%) and design software/licensing (72%).”

2. E2 Semiconductors and the Semiconductor Industry Congressional Research Service · 19 April 2023

   “A small share of global manufacturing capacities is physically located in the United States for wafer fabrication (11%) and ATP services (5%); the majority of fabrication and ATP facilities are located in China, Taiwan, South Korea, and Japan.”

   “Taiwan manufactures roughly 85 percent of global leading-edge logic chips, and China and Taiwan together produce 63 percent of legacy logic chips. By contrast, the United States has zero onshore leading-edge capacity and only 8 percent of global legacy logic capacity.”

   “TSMC currently operates two fabs in America, including a freshly established 12-inch fab in Arizona, which reportedly started mass production of 4nm chips in 4Q24, and an 8-inch fab in Washington state.”

The CRS report finds that US-headquartered firms had the largest share of global chip-design revenue (46% in 2021) [E1]. It also finds that only 11% of global wafer fabrication capacity is located in the US [E2]. CSET reports that the US had no onshore leading-edge logic capacity and only 8% of legacy logic capacity, while Taiwan produced about 85% of leading-edge logic [E3]. This supports the claim's main point. However, the US still has some fabrication capacity (11% of global wafer fabrication capacity [E2] and 8% of global legacy logic capacity [E3]), and TSMC's Arizona fab reportedly began mass-producing 4nm chips in 4Q24 [E4]. So saying the US "can't produce chips effectively" overstates the case somewhat, which fits the "mostly true" criterion.
