Spot memory prices surge to four times contract prices as AI demand overwhelms supply

A 36GB HBM3E memory stack now costs about $2,100 on the spot market. Under long-term agreements, that same stack runs between $365 and $510. That’s a four-to-five-times markup, the kind of pricing gap that usually screams “bubble.” Except in this case, industry analysts are arguing the opposite: the memory chip supercycle may just be warming up. The culprit, unsurprisingly, is artificial intelligence. The insatiable demand for high-bandwidth memory to power AI training and inference workloads has vacuumed up wafer capacity that would normally go toward conventional DRAM and NAND production. The numbers behind the squeeze Server DRAM contract prices climbed 45-50% quarter-over-quarter in Q4 2025. TrendForce projects those gains will accelerate to 55-60% or more in Q1 2026. Overall tracked memory contracts have posted year-over-year price increases surpassing 343.55% as of early September 2026. To put that in perspective, a component that cost a dollar a year ago now costs roughly $4.44. For hyperscalers building out massive AI clusters, that kind of inflation doesn’t just sting. It reshapes entire capital expenditure plans. Samsung Electronics has responded by locking roughly 70% of...
