Scroll down. The same trend is happening for DDR5 prices. It's AI demand.

More specifically, it's OpenAI quietly contracting away 40% of global DRAM capacity, only to build wafers of memory and shove it in a warehouse.

They're not the only player trying to buy more RAM. Every hyperscaler is also growing.

AWS, MS, Oracle, and Google demand is growing ~100% in 2026. Nvidia demand is growing ~50% in 2026. Supply isn't forecast to improve at all until H2 2026 and it's probably ~all spoken for through at least EOY 2026.

That's from June 2025. It's not relevant to current situation — prices have been rising since October 2025 due to agreements that became public in the same month.

Is he saying the supply of ddr4 went down because they’re switching to ddr5?
