Analysis
Samsung Electronics has raised prices for some of its advanced contract chipmaking services by up to 15% for new orders, as AI-driven demand outstrips the foundry's available capacity. Prices for 4-nanometer SF4 process wafers used by US and Chinese customers rose 10-15% in July, with 5-nanometer wafers climbing a similar amount, according to reporting this week.
The increase reflects a supply squeeze one level up the chain: TSMC, the dominant foundry for leading-edge chips, has pre-sold all of its 3-nanometer capacity through 2027 and its entire 2026 2-nanometer output to Apple, Nvidia and AMD. That leaves Samsung as the next-best option for customers who can't get TSMC allocation, giving Samsung pricing power it hasn't had in a foundry business that has historically trailed TSMC on both yield and market share.
“Whether Samsung can sustain these prices once TSMC's capacity constraints ease, or whether this is a temporary premium tied to today's specific shortage, remains unclear.”
Chinese firms are reportedly accepting the steepest increases, a consequence of US export controls that have pushed Chinese chip designers toward whatever advanced foundry capacity remains available outside restricted supply chains. That dynamic -- US policy constraining where Chinese customers can source chips, and Samsung benefiting from the resulting demand redirect -- has been a recurring theme through 2026's chip cycle, showing up again this week in separate reporting that Nvidia's H200 chips are flowing back into China in small volumes under a licensing framework.
Despite the pricing power, Samsung's Seoul-listed shares fell 7.8% the same day the price hikes were reported, as the broader Kospi index dropped 5.8% on unrelated bond-market jitters -- a reminder that even good company-specific news doesn't insulate a stock from a macro selloff. Samsung has separately been building out 2nm chip talks with Anthropic and Meta and inked HBM megadeals with SK Hynix earlier this year, part of a broader push to convert AI-driven demand into long-term supply contracts rather than one-off price increases.
The risk for Samsung's customers is straightforward: a 10-15% cost increase on leading-edge wafers compresses margins for every AI chip startup and hyperscaler relying on Samsung capacity, at a moment when many of them are already burning cash to build out training and inference infrastructure. Whether Samsung can sustain these prices once TSMC's capacity constraints ease, or whether this is a temporary premium tied to today's specific shortage, remains unclear.
