Industry Analysis
Micron’s HBM4 rollout is redefining AI hardware architecture, shifting toward a 'memory-defined compute' paradigm that compels GPU vendors to redesign platforms. U.S. export controls elevate compliance costs but paradoxically strengthen Micron’s pricing power outside mainland China. Competitors like Samsung and SK Hynix will likely lock in customers via prepayments to counter Micron’s lead. Broadcom’s caution reflects ASIC economics—not broad AI demand erosion. With 2026 HBM capacity already sold out, price resilience will persist despite macro headwinds. The real bottleneck ahead isn’t memory demand, but whether advanced packaging (e.g., CoWoS) can scale to match HBM4 integration timelines—this will dictate AI chip delivery cadence through 2027.
