Memory chip executives are confirming a supply crunch that will persist through at least 2028, driven by AI's voracious appetite for high-bandwidth memory (HBM) and server DRAM.
Micron Technology CEO Sanjay Mehrotra told investors this week that demand for his firm's memory will exceed supply over the next two years. He said 75 percent of Micron's HBM output for 2027 is already sold out, with prices significantly higher than 2026 levels. Most current memory sales discussions now focus on 2028 supply.
The economics are brutal for consumer-facing business. Micron discontinued sales through its Crucial consumer brand in December 2025, shifting entirely to business-to-business sales of HBM for AI and DRAM for servers. The margin spread and contract certainty on enterprise silicon far exceed what consumer OEMs will pay.
Samsung Electronics EVP Kim Taewoo corroborated this trajectory, stating that HBM will account for nearly 30 percent of DRAM manufacturers' wafer capacity in 2027—up from 20 percent today. That reallocation directly starves consumer devices. Personal computers, smartphones, streaming sticks, and gaming consoles are all competing for capacity that manufacturers have redirected to AI and cloud infrastructure.
Consumer prices have already buckled under the constraint. Prebuilt PC costs have risen, and original equipment manufacturers are shipping lower RAM configurations at elevated prices.
New manufacturing capacity offers little relief. Micron's new clean rooms, scheduled to come online in 2028, will ramp production gradually. Future node transitions also yield diminishing productivity gains per wafer, creating structural headwinds for supply growth. Mehrotra said the company does not foresee when supply will catch up with demand, citing persistent growth in larger AI models, expanding context windows, increased concurrency, and proliferation of AI agents across enterprise and consumer sectors as continuous drivers of memory consumption.
The capital allocation decision is clear: Micron and Samsung are betting the next cycle's value lies in securing long-term, high-margin contracts with cloud providers and AI chipmakers, not in chasing commodity consumer volumes. That structural shift locks in the supply shortage for the rest of the decade.
