Micron’s pre-earnings dip reflects investor skepticism over whether memory can keep pace with AI compute demands. Broadcom’s Jalapeño chip—built on 3nm EUV and co-developed with OpenAI—intensifies pressure on HBM supply chains, forcing DRAM makers to accelerate HBM3E/HBM4 ramp. Failure to demonstrate volume capability risks ceding ground to Samsung and Taiwan, China-based rivals. Tightening U.S. export controls on advanced lithography tools inflate non-U.S. firms’ EUV access costs and delay timelines, reinforcing TSMC’s dominance in the 3nm ecosystem. Over the next 12–24 months, AI capex will pivot toward 'compute-memory co-optimization'; logic leadership alone won’t suffice. Control over HBM supply chain resilience—not just transistor density—will dictate hardware pricing power. While falling oil prices ease macro concerns, the real semiconductor battleground lies in building geopolitically compliant, redundant advanced packaging capacity amid fragmentation risks.
