Capital markets are experiencing a severe hardware reality check. The frantic scaling of artificial intelligence infrastructure has finally triggered the kind of physical supply bottleneck that sends shockwaves far beyond Silicon Valley server rooms. When South Korea’s Kospi index closed 4.6% higher on Monday, driven by a 5.7% surge in Samsung shares and an 8.3% jump in SK Hynix, it was not just a routine market bounce. It was a direct reflection of an underlying semiconductor crunch where raw processing ambition hits the hard wall of memory wafer capacity.
The numbers behind this manufacturing scramble are staggering. Global DRAM market revenue reached $154.73 billion in the second quarter of 2026, marking a violent 59.5% increase from the previous quarter. Samsung captured $60.98 billion of that total, growing its revenue by 63.4% and pushing its market share to 39.4% as it races to scale sixth-generation high-bandwidth memory, or HBM4. Meanwhile, SK Hynix posted $38.59 billion in revenue, representing a 37.9% gain, though its market share adjusted to 24.9% due to the lag effects of long-term HBM contract structures. Micron Technology tracked close behind with $36 billion in revenue, up 65.5% and claiming a 23.3% share. Inventories remain remarkably lean across the entire sector, setting the stage for DRAM prices to climb another 13% to 18% in the third quarter.
This margin expansion will inevitably compress downstream device makers. PC and smartphone manufacturers lack the pricing power to easily absorb double-digit memory cost hikes, meaning hardware commoditization is about to accelerate. Yet upstream fabricators continue to command immense pricing leverage. With analyst estimates for Samsung’s third-quarter operating profit climbing to 114.19 trillion won and SK Hynix tracking toward 78.80 trillion won, the memory duopoly holds the keys to the entire generative AI economy. As long as frontier model builders prioritize raw compute scaling over cost efficiency, these fabrication titans will capture the lion’s share of the industry’s cash flow.
