Samsung raises foundry prices up to 15%
Samsung hiked 4nm and 5nm contract chip prices by 10-15% as TSMC capacity fills. The second source just got more expensive — price your AI stack accordingly.
The cheap alternative is no longer the cheap alternative. Reuters reported on August 19 that Samsung raised prices on some advanced contract chipmaking by as much as 15% for new orders, as AI demand fills the leading-edge capacity that used to have slack in it. The Samsung foundry price increase is the clearest read yet on where the floor under your compute bill is heading.
What actually happened
Per Reuters, citing two people familiar with the matter, wafers on Samsung's SF4 (4nm) and SF5 (5nm) processes went up 10% to 15%, with some 8nm work rising around 10%. The SF4 hike is not uniform: customers in China and the U.S. saw 10-15% from the prior month, while customers in Taiwan saw 5-10%. Samsung raised SF4 pricing in July as well. The company has not publicly confirmed the figures.
Context matters here. Samsung booked about 7% of global foundry revenue in Q1 2026 against TSMC's 70%-plus, and its foundry business has run at a loss since 2022. Its SF4 line at Pyeongtaek has been at full capacity since late 2025. Lee Min-hee of BNK Investment & Securities told Reuters that if Samsung holds these prices, the foundry unit could turn profitable as early as next year. Demand from Chinese AI customers constrained by U.S. export rules is a meaningful part of the pull. Reuters has the full report.
Why chip pricing matters for your business
You will never buy a wafer. You will buy tokens, GPU-hours, and SaaS seats priced off both — and every one of those has a silicon cost underneath it.
Here is the structural part. For two years the story was "TSMC is expensive and full, so the overflow goes to Samsung at a discount." That overflow valve is closing. When the number two supplier raises prices into a shortage, it is not competing on price anymore, it is rationing. There is no cheaper tier left to route to, which means the downstream price of inference has one direction to go for a while.
That does not mean panic. It means stop treating today's per-token rate as a permanent input to your unit economics. Know what each automated workflow actually costs you per run. Know which ones would still pencil out at double. The ones that would not are the ones to redesign now — smaller models, cached results, fewer round trips — while you are choosing to, not while a rate card is forcing you to.
Key takeaways
- Reuters reports Samsung raised SF4 (4nm) and SF5 (5nm) contract prices 10-15% on new orders, with some 8nm work up about 10%
- SF4 increases ran 10-15% for China and U.S. customers, 5-10% for Taiwan; sourced to two people familiar, not confirmed by Samsung
- Samsung held roughly 7% of Q1 2026 foundry revenue vs TSMC's 70%+, and its foundry unit has lost money since 2022
- The discount overflow valve for full TSMC capacity is closing — expect upward pressure on inference pricing, not relief
- Cost every automated workflow per run now, and redesign the ones that break at 2x while it is still your choice
Do you know what each AI workflow costs you per run? Most operators do not, which is why a rate change turns into a surprise instead of a decision. Run the numbers on your automation spend, or have us audit where your tokens actually go.
