SK Hynix breaks records and lifts Wall Street🔥 Memory sold out through 2029🚨 - XTB.com

The 2029 sellout signal is not a cyclical shortage—it is a structural lock-in of the memory layer by AI compute infrastructure. Once HBM becomes a rigid bottleneck for GPU clusters rather than an optional add-on, pricing power shifts from volume-based to scarcity-based. On the technology chain, the 1c nm DRAM node and HBM4's 12+ layer stacking force a new capex cycle upstream. Lam Research's TSV etch and Applied Materials' bonding equipment now carry order visibility into 2027. NVIDIA's Rubin architecture demands 40% more HBM bandwidth than Blackwell, meaning the 2026-27 capacity gap is exponential, not linear. Compliance risk: SK Hynix's Wuxi fab still accounts for over 30% of capacity. If BIS export controls extend to HBM4, China revenue faces a cliff-edge decline, compressing margins. Competitively, Samsung's HBM3E yield ramp lags by a full quarter; Micron holds just 8% global share. The 2029 order book is effectively a "time moat"—rivals need 18 months minimum from equipment delivery to customer qualification. 12-24 month outlook: If AI capex enters a digestion phase around Q2 2026, spot DRAM may retrace 15-20%, but HBM contract prices stay rigid due to long-term agreements. The real risk surfaces in 2027 when Samsung's 1c nm capacity hits the market en masse—standard DRAM could repeat the 2023 inventory glut.
