South Korean memory chip giant SK Hynix's market capitalization has breached the $1 trillion mark.

As the global leader in the HBM (High Bandwidth Memory) sector, SK Hynix has been revalued by capital markets at the trillion-dollar level, directly reflecting the scarcity and pricing power of AI memory. HBM is essential complementary memory for high-end AI accelerators (such as NVIDIA GPUs), and the tightness of its supply often directly determines the production capacity ceiling of GPUs.

SK Hynix's recent advance sampling of 12-layer HBM4E and intensifying competition with Samsung both signal that next-generation HBM supply is accelerating, while demand remains robust enough to sustain a trillion-dollar valuation. In other words, the market believes the shortage of AI memory will persist for a considerable time to come.

For downstream computing companies like yours, HBM is a critical upstream variable in GPU cost structures: the tighter and more expensive HBM becomes, the more constrained GPU pricing and availability grow. SK Hynix's market capitalization and capacity trajectory serve as important forward-looking indicators for assessing future GPU supply tightness—the steeper its rise, the more it typically signals upstream constraints.
