2027 memory output is reportedly already sold out — buyers getting 60–70% of what they asked for

Industry reports say the three memory makers — Samsung, SK hynix and Micron — have sold out their full 2027 DRAM and HBM output, with NAND capacity for the remainder of 2026 close behind. Allocation negotiations for next year were reportedly wrapped months earlier than the usual cycle, with most buyers receiving only 60–70% of the volumes they requested. Suppliers are said to be converting demand into three-to-five-year long-term agreements backed by advance deposits, and to be filling cloud providers, hyperscalers and AI labs first, leaving consumer electronics last in the queue. ADATA chairman Simon Chen has publicly confirmed that the top three vendors' 2027 capacity is spoken for. Separately, TrendForce said on the same day that DRAM supply stays tight through 2027 — tight enough that Nvidia is trimming HBM configurations on Rubin Ultra.

These are channel and analyst reports, not company statements: none of the three makers has confirmed the sell-out on the record.

Why it matters

If it holds, the pricing power the three suppliers gained in 2026 is now locked in for a second full year, and it arrives as contracted revenue rather than spot upside — Micron already guided to a shortage running past 2027, and this is what that guidance looks like once it is papered. Advance deposits and multi-year terms shift the risk to buyers and give the makers visibility to fund the new HBM-focused fabs Korea's national plan is built around. The squeeze lands on everyone downstream of AI: at 60–70% fill rates, consumer devices and smaller buyers are the adjustment variable, not the AI customers being served first.

What to watch

Whether any of the three confirms the sell-out on an earnings call, whether 2027 capacity additions arrive early enough to loosen allocation, and how HBM4 pricing settles once Nvidia's lower Rubin Ultra configurations are factored in.
