In this Macro Minute for Tuesday, October 13th, 2026, skipper Darius Zell opens with the executive summary from the morning notes. The most important development is that China's semiconductor champion, CXMT, claims it has reached a chip technology milestone that rivals have chased for years, a claim that hurt the bull case for global memory chip makers. On the macro side, the September NFIB Small Business Optimism Survey mildly supported the jobless recovery and cooling housing and labor themes, supported the staking inflation theme, and backed the consensus forecast of affirming inflation. However, the same survey challenged the consensus forecast of accelerating growth and challenged the resilient U.S. economy paradigm, including the run-it-hot and productivity boom themes. For portfolios, Zell notes that CXMT's CEO says the company has pursued this breakthrough since its founding a decade ago and holds more patents in the area than rivals, a clear signal of China's strategic STEM advantage. He recalls Huawei's May introduction of Tua scaling laws, an alternative to Moore's law, with logic folding already used in this year's smartphones. The rising probability of China winning the AI race has contributed to the Philadelphia Semiconductor Index heading for a sixth straight daily loss, now 7% below its October high. The sell-off comes ahead of earnings from ASML and Taiwan Semiconductor that may show whether AI spending is paying off fast enough to justify elevated CapEx. The AI debate has shifted from whether compute demand exists to whether investors will keep funding a build-out that earns adequate returns, with Barclays estimating AI revenue near $250 billion annually against potential ecosystem needs above $1 trillion per year.
