📈 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.

IS THIS A TRADE? 🚫 Not a trade — conviction 44.9 is EMBER, below WATCH (45) and far from the GREEN entry bar (65). If more weighted voices pile on, it climbs; two mentions isn't conviction. direction semantics: bullish = the plays below are expected to RISE if the thesis is right → expression is long.

also touching these tickers, same direction: AI compute capex supercycle has 12-24 months of runway 87 (SMH) · Nvidia + Hugging Face makes NVDA the open-source AI champion 58 (SMH)

“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.”
