TSMC controls advanced fabs
Analysts say TSMC now accounts for roughly 72% of advanced chip production, consolidating its role as the backbone of modern hardware supply chains while Samsung leans on its memory strengths to stay competitive. That market concentration raises single‑vendor risk for high‑performance workloads and design‑in decisions. (fool.com, thedailyupside.com)
Counterpoint’s quarterly pure‑foundry update for Q4 2025 attributes TSMC’s lead to an accelerating N3 ramp, strong utilization of 4/5nm nodes and expanded CoWoS advanced‑packaging capacity. (counterpointresearch.com)) TSMC reported NT$1.046 trillion in revenue for the December quarter and said 77% of wafer revenue that period came from 7‑nanometer or smaller process nodes, while guiding $52–$56 billion in capital expenditure for 2026. (cnbc.com)) Industry reporting names Nvidia and AMD as primary drivers of demand for advanced logic on those nodes, with Counterpoint and CNBC pointing to NVIDIA’s Blackwell GPUs and other AI accelerators as major contributors to utilization. (counterpointresearch.com)) Samsung’s foundry arm recorded roughly $12.6 billion in revenue and was reported at ~7.2% market share, and Korean press cited foundry yields as low as about 50% versus competitors’ higher yields as a factor in lost customers. (thedailyupside.com)) Samsung is exploiting its memory portfolio—formal HBM4 supply agreements with Nvidia and AMD and plans for a joint HBM facility—to offer bundled logic+HBM solutions that analysts say could sway select hyperscaler and accelerator deals. (biz.chosun.com)) Market trackers show the top foundries’ revenue jump in 2025 and a broad‑based increase in wafer pricing, with TrendForce and Counterpoint reporting strong industry growth driven by AI‑related orders. (trendforce.com)) Reporting also documents concrete diversification moves: Samsung agreed to supply extra HBM4 to AMD and entered talks to potentially manufacture next‑generation AMD chips as part of those memory supply arrangements.
