HBM demand and server refresh cycles drive DRAM price increases as manufacturers weigh OpenAI capacity needs
Saturday, December 20, 2025 at 09:23 AM
DRAM price increases are being driven by rising HBM demand and a replacement cycle in general purpose servers, specifically from Meta and Microsoft. Memory manufacturers remain skeptical of OpenAI's projected demand for 900,000 wafers per month and may require OpenAI to fund CapEx or sign non-refundable, non-cancelable contracts to secure capacity.
Context
Memory markets are tightening as Microsoft and Meta lead an aggressive general-purpose server refresh cycle. This surge, combined with unprecedented demand for High Bandwidth Memory (HBM) for AI accelerators, is pushing DRAM prices higher. Supply remains constrained as manufacturers reallocate production lines to high-margin AI components, leading to a supply-demand mismatch expected to persist through 2025.
Manufacturers remain skeptical of OpenAI CEO Sam Altman’s projected demand of 900,000 wafer starts per month. To mitigate the risks of such a massive capacity build-out, memory producers may require OpenAI to fund capital expenditures or sign non-refundable, non-cancellable (NRNC) contracts. This dynamic shifts the financial risk of production expansion from the manufacturers to the AI giants, marking a significant evolution in the semiconductor supply chain's risk profile.
