AI-driven demand has triggered an 'unprecedented supercycle' for dominant global memory suppliers (Samsung, SK Hynix, Micron).
Predictor: Samsung executives
Prediction text
AI-driven demand has triggered an 'unprecedented supercycle' for dominant global memory suppliers (Samsung, SK Hynix, Micron). | unprecedented supercycle | Memory ASP + gross margin trajectory
Key catalyst: Memory ASP + gross margin trajectory
Watch events: Memory ASPs; gross margins; capex announcements.
Verbatim quote
unprecedented supercycle
Resolution evidence
Memory ASPs +50-100% YoY for HBM; DRAM spot prices 2x; all three memory vendors posting record revenue/margins.
Predictor: Samsung executives
Evidence about this node from Samsung executives is multiplied by κ in /api/intake. Lower κ = less weight; floors at 0.10 (effectively silenced) and caps at 1.00 (full weight).
Reference class: memory_supercycle_2y
Named memory-market supercycle (DRAM/HBM) persists/intensifies into stated year (n>=2y forward)
Tetlock-style outside view: at TRF=1 (just predicted), outside view dominates (w_in=0.3). At TRF=0 (deadline), inside view dominates (w_in=1.0). The blend regularizes overconfident inside views toward the historical base rate.
