Samsung Locks Up 70% of Memory Production Capacity, Driving HBM Spot Prices Higher
nashnova research
Samsung Electronics has locked in 70% of its memory production capacity through long-term agreements, as AI-driven HBM demand tightens chip supply and pushes spot prices higher.
How much capacity did Samsung lock — and why?
According to Digitimes, Samsung has secured up to 70% of its memory production capacity through long-term supply agreements (LTAs).
The driver is relentless AI-infrastructure demand for HBM — high-bandwidth memory, a type of high-speed RAM built specifically for AI chips.
This means → Samsung expects HBM to stay undersupplied for several quarters and is pre-selling capacity to major customers rather than leaving it for the spot market.
Why are spot prices rising as a result?
With 70% of capacity tied to long-term contracts, the volume of HBM available on the open spot market shrinks significantly.
In plain terms = the total pie hasn't grown, but seven slices out of ten are already spoken for — the remaining three must serve every other buyer, so prices get bid up.
The short-term supply–demand imbalance deepens, and spot buyers lose bargaining power.
Can this move help Samsung close the gap with SK hynix?
In the HBM market, SK hynix is the acknowledged leader in both technology and share. Samsung's mass capacity lock-up has a clear aim — trade supply-side certainty for market share.
Details on specific contract customers and lock-up durations have not been fully disclosed; the original report sits behind a paywall.
This reflects a strategic pivot from "catching up on tech" to "locking down capacity," but whether it actually narrows the gap with SK hynix remains the key validation point the market is watching.
