Postmarket Sep 25: S&P +0.5%; oil fade; SOX +1%

S&P +0.5% / SOX +1.4%. 10y ~5.18%; Brent ~$98. AKAM held green, ORCL soft. DoD Anthropic bar upheld; China DC model.

Edition: postmarket

The lead

S&P +0.51% — closed 7,743.41 (+39.28) vs Thu 7,704.13; Nasdaq +0.48% to 27,068.72; Dow +0.93% to 51,828.62 (Yahoo; Yahoo NQ; Yahoo DJI). Cash followed the firm ES open into a green session — Mag7 mixed, SOX led, not a broad AI-capex re-rating.

  • Path / breadth — SOX +1.4%; Mag7 split; energy soft on the oil fade. SOX +1.41% to 12,668.93. MSFT +3.66% and AAPL +1.53% led Mag7; NVDA +0.22%; GOOGL +0.46%; AMZN ~flat; META −3.33% (giveback after Thu’s +4.5%); TSLA −1.54%. AKAM +3.20% to 113.94 — held green after a ~$125–128 gap open faded hard. ORCL −1.75% to 137.10; OWL +0.76%. XLE −0.86% with crude.
  • 10-year ~5.18% — Yahoo settle 5.184 (+~2bp from Thu 5.162); session poked ~5.23 then faded. WSJ afternoon: bond selloff paused; 10y still a ~19-year closing high and a week that ended sharply higher.
  • Oil — Brent stayed off three-digit; Hormuz-reopen hopes held the fade. WTI ~$92.8 (−~1.9% vs Thu $94.61); Brent ~$97.7 (−~8.4% vs Thu $106.6). WSJ live: Dow led on Hormuz-deal hopes; crude −~2% on their print (WSJ).
  • Archive afternoon: D.C. Circuit 2–1 upholds DoD supply-chain risk label on Anthropic (Claude ban for DoD/contractors preserved; split with N.D. Cal. vacatur). SemiAnalysis China Datacenter Model preview — China fleet >24GW; ByteDance ~1/5 capacity, mostly leased; BAT 2Q26 capex $20B.
  • Session carry (not new docs): Akamai–Anthropic ~$11.6B offtake — gap faded, close still +3%. Oracle Jupiter FM — ORCL extended soft (−1.8%). SoftBank OpenAI HY still on calendar (settle Sep 29 / OpenAI ~Oct 1).

Morning’s open question — Jupiter FM + sticky ~5.18% 10y vs softer oil and Akamai offtake reopening Mag7/SOX after summit optics — resolved mixed toward a tape reopen, not a financing reopen: cash green, SOX +1.4%, Brent held ~$98, but 10y stuck ~5.18%, ORCL kept sliding, AKAM gave back most of the gap, and Mag7 was MSFT/AAPL-led rather than NVDA/ORCL breadth. Summit still optics over chip/AI financing relief.

Open question: Into SoftBank settle Sep 29 / OpenAI ~Oct 1, does a sticky ~5.18% 10y plus ongoing Jupiter lease stress still force Stargate/DC credit pressure, or does the oil fade + SOX reopen stick once aftermarket HY spreads print?

Positioning

AI capex durability — China MW ledger and DoD bar are not a U.S. hyperscaler guide-down; Jupiter stress is still schedule/financing friction. SemiAnalysis’s China Datacenter Model puts >24GW under mainland AI infra (ByteDance ~1/5, mostly leased; BAT 2Q26 combined capex $20B / negative FCF) — consistent with global compute-bound spend, silent on whether a top-four U.S. hyperscaler guides sequential capex down. Anthropic’s same-week Akamai CPU-cloud offtake sits beside a still-live DoD supply-chain bar (D.C. Circuit 2–1) — commercial compute lock vs federal-procurement exclusion, not a demand cut. Theme falsifier unmet; financing/site friction (Jupiter FM, TX water) remain closer than SoftBank oversubscription optics.

HBM supply binds — China facility MW ≠ accelerator shipments. The same SemiAnalysis preview flags chip/export constraints as a dark cloud beside vacancy/price competition — useful for build-speed comparisons, not a third-supplier or HBM-per-accelerator break.
