📈 DRAM/HBM: the bottleneck that matters
DRAM — specifically HBM/SOCAM/LPDDR for AI servers — is THE binding constraint of the AI buildout: only three makers (Micron, SK Hynix, Samsung), 2026 supply sold out, new supply-chain agreements with price FLOORS above prior-cycle-peak gross margins (~50% of Micron revenue), DRAM heading to 30-40% of all hyperscaler capex, and the stocks still trade cross-sectionally cheap vs the rest of AI. Risks: CXMT floods consumer-grade DRAM from China; Elon's TerraFab adds supply in years, not quarters.

“Today, they all live in NVIDIA and the memory industry, and they're being shifted towards the hyperscalers”
“And then there's he's got to buy memory like and there's memory shortage and in that.”
“memory capacity and bandwidth are foundational to the performance of every AI model. ... this bottleneck is going to be with us for a while. ... the floor pricing in these new contracts is ahead of prior cycle peaks from a gross margin perspective. ... DRAM is probably going to be 30 to 40 percent of all hyperscaler capex next year.”
