Bear market shadows a supply-constrained boom as capital reshapes the physical AI stack
- The $2.1 Trillion Bear Market: Kimi K3 Tests Whether Chip Demand Was Priced on FictionBroadcom reported $22.19 billion in revenue and $2.44 EPS against $2.39 expected, and the stock fell 12% in a day.
- Memory Stays Sold Out: Bernstein Sees HBM 2-2.5x, Adding 30% to Hyperscaler AI CapexLooking at the problems listed:
- TSMC's $265B Arizona Bet at Double Speed: Five 2nm Fabs Ramp as Investors BalkTwo men who both work in the same building told two different stories last week, and only one of them moved markets.
- AMD Wins Azure for Helios as Meta Turns Its 5GW Buildout Into a CloudFuturum Group puts the AMD Helios rack at $5 million to $5.5 million a copy. Nvidia's second-generation Vera Rubin rack, by the same estimate, runs $3.5 million to $4 million.
- Chinese Chipmakers Route Around Sanctions: Optical Super Nodes and an Edge PivotOne hundred twenty-eight. That is the ceiling copper imposes — the maximum number of GPUs you can lash together electrically inside a single server before the wires themselves become the bottleneck.
Threads we are following
- Whether the US administration's cybersecurity-grounded ban push against open-weight Chinese models actually advances, and which layer of the stack it protects.
- Whether hyperscalers adopt MediaTek-style direct memory sourcing to bypass Nvidia's markup, and how fast the 4x amplification could unwind
- Whether Intel 18A yields hold up under real production volume, and how Samsung Taylor 2nm compares as a third second-source contender
- Whether ROCm can close the CUDA gap fast enough to make AMD a second source developers actually target, not just a hedge hyperscalers underwrite
- Whether Taiwan's first National Security Act indictment triggers a wave of prosecutions that chokes the talent pipeline China's group-computing strategy depends on
