SK Hynix Posts Record Quarter as AI Memory Demand Outruns Supply

The signal here is less the record revenue than the visibility: management putting sold-out DRAM and HBM capacity through 2029, and demand outpacing supply through 2030, reframes AI memory as a structurally constrained input rather than a cyclical one. That matters for anyone exposed to data-center buildout economics, where memory availability, not just GPU supply, can set the pace. The open question is whether this tightness proves durable enough to hold pricing through the period SK Hynix describes, or whether capacity additions elsewhere eventually loosen it.
