Twenty-five manufacturers produced leading-edge chips 20 years before 2021, but by 2021 only TSMC (Taiwan), Intel (United States), and Samsung (South Korea) had facilities capable of producing the most advanced chips.

Notes on verification

Confirmed by CBS 60 Minutes interview with Intel CEO, Wikipedia's semiconductor industry article, Intel SEC filing chart, and industry analyst sources, all converging on the 25-to-3 consolidation narrative, though exact baseline year varies slightly across sources (1990s vs ~2001). [cascade flags: wikipedia_dropped_other_sources_exist | tier=silver indep_score=0.988 clusters=4 claim_tier=notable | framework convergence=partial on Widely-cited industry consolidation narrative originating largely from Intel's own historical fab-count analysis and reiterated by Intel executives (e.g., Pat Gelsinger) and various industry commentators (upstreams: Intel corporate roadmap analysis (2014 SEC filing), Pat Gelsinger / Intel public statements, Boston Consulting Group and Semiconductor Industry Association (SIA) reports (general chip consolidation narrative)) — publishers independent, evidence may not be | kind=empirical eligibility=high (extractor: empirical/medium)]
