Original: HBM 부족해도 못 산다…AI 빅테크 '메모리 확보 전쟁' - v.daum.net
Korean press reports AI hyperscalers cannot secure HBM even when willing to pay, intensifying a 'memory procurement war' as supply remains tight through 2026. SK Hynix and Samsung — the dominant HBM suppliers — hold pricing leverage, while Micron benefits as the third source; NVIDIA and other AI chip buyers face allocation constraints that could cap GPU shipments.
Why it matters: Direct HBM supply-constraint signal naming hyperscaler demand exceeding supply — materially bullish for SK Hynix/Samsung/Micron pricing power and a near-term overhang on NVIDIA shipment guidance.
