AI chipmakers see momentum fade after demand boom

NVIDIA and Broadcom, the twin pillars of the AI infrastructure buildout, both retreated on May 12-13 after a months-long rally that had decoupled them from broader equity weakness. The selloff is not fundamentals-driven; rather, traders are taking profits after a 40%+ rally year-to-date and reassessing whether the memory-chip bottleneck truly justifies $3 trillion in AI spending. Bloomberg analysis shows that while memory-chip shortages remain structural (with global supply tightening across DRAM and NAND), some early indicators of oversupply in specialty chips are appearing, and lead times for certain components are starting to normalize.

The complexity is nuanced. AI capex is not peaking; hyperscalers remain committed to spending, and large language model training still consumes unprecedented amounts of memory bandwidth. But the narrative has shifted from scarcity-driven panic buying to disciplined, phased deployment. Broadcom and other suppliers are guiding conservatively on utilization, and gross margins for legacy products are under pressure as competition intensifies. NVIDIA's stock, which had treated the AI cycle as a perpetual tailwind, is now vulnerable to any guidanceCompany-issued forecasts of future financial performance. miss or indication that customer spending is moderating.

The energy and memory bottleneck is real but is increasingly being managed through higher prices and inventory discipline rather than spot-market bidding wars. Chip stocks that had decoupled from valuation models are now re-coupling as the risk-free rate stays elevated and real returns matter again. Western Digital, a less-obvious beneficiary of the AI boom, has actually outperformed NVIDIA on a one-month basis, suggesting investors are rotating to less-crowded exposure and more diversified semiconductor bets.

Bull case: AI capex cyclically accelerates through 2026, memory remains constrained, and NVIDIA's networking and custom-silicon dominance widens. Bear case: Hyperscalers build redundancy and manage-to-inventory, gross margins compress, and competitive pressure from AMD and emerging players fragments the once-oligarchic market. The key watch is quarterly guidanceCompany-issued forecasts of future financial performance. and customer concentration metrics in upcoming earnings.
