Memory Chipmakers Aren't Spending Too Much—They're Spending Too Little

Memory chip spending surge reflects AI-driven structural demand shift, not cyclical excess like previous booms.

When Micron announced plans last month to increase its fiscal 2026 capital expenditure by $5 billion—bringing total investment to over $25 billion—and SK Hynix committed more than $8 billion for cutting-edge EUV equipment, investors responded with notable skepticism. The semiconductor industry’s collective memory kicked in, and the market reaction was decidedly lukewarm. Haven’t we seen this movie before? The one where memory manufacturers chase boom-time profits with massive capacity buildouts, only to crash spectacularly when oversupply floods the market and prices collapse?

But we believe that dismissing today’s spending surge as yesterday’s mistake ignores three fundamental shifts that make this cycle radically different: the nature of AI demand, the maturity of industry discipline, and the structural economics of modern memory production.
