Premarket Sep 24: SoftBank prints; soft futures; Trump–Xi

The lead

S&P futures ~−0.5% — Dow e-minis ~−0.27% / Nasdaq-100 e-minis ~−0.98% by ~8:48am ET after Wednesday’s cash fade (S&P 7,706.03 −0.75% / NQ 26,936.04 −1.13% / Dow 51,511.59 −0.68% / SOX 12,534.27 −1.23%) (Reuters; Yahoo).

• Rates still biting — 10-year ~5.13%; 30y highest since 2004. CNBC overnight: 10y poked ~5.133% (July 2007 high); 30y ~5.44% / ~5.435% early Thursday. FedWatch ~71% October hike (Reuters; CNBC later >75%); Williams: another hike this year “reasonable.”
• Oil — Brent still three-digit; energy pressure on airlines/cruises. CNBC early: Brent ~$103.66 (−0.5%) / WTI ~$92.68 (−0.6%); Reuters flags Middle East UN barbs and a potential U.S. diesel-export ban as the tape drivers.
• SoftBank OpenAI HY — issued, not just launched. ~$11.1B ($10B USD + €1B) senior notes priced; coupons 8.625% / 9.25% / 9.75% on USD 3.5y/5.5y/7.5y and 7.125% / 8% on EUR; settle expected Sep 29; proceeds fund the $10B final OpenAI tranche (~Oct 1) and cancel the remaining $10B undrawn bridge (SoftBank; Reuters; updated news). Tokyo shares jumped >7% on reopen after the holiday (CNBC); Reuters later had the session closing +0.6%.
• Trump–Xi dinner today — AI regulation, trade truce (Bessent: extended to Jan 10), rare earths, Iran/Taiwan on the table; Huang / Altman / Pichai among expected tech CEOs (Reuters; prior CNBC). META / NVDA soft in the premarket narrative (~−1.8% / ~−1.1% Reuters).
• Archive overnight: BlackRock/IFM exclusive talks on Stack Asia DCs up to ~$25B; DeepSeek ARR ~$1B with >70% compute still in training; GS Lynam AI credit and SemiAnalysis ClusterMAX 3.0 shipped. Ramp 5.73% / Claude ART already in yesterday’s postmarket — not rehashed.

Yesterday’s open question — SoftBank print vs Mag7/SOX under a ~5.1% 10y and three-digit Brent — partly resolved on the credit side: the package cleared at 8.625–9.75% USD. Cash session still has to answer whether that clearing yield, sticky oil, and Trump–Xi optics re-open the bid or keep Mag7/SOX under pressure.

Open question: SoftBank cleared at ~8.6–9.75% into a ~5.1% 10y and three-digit Brent — into Trump–Xi tonight, does that HY print stabilize the AI financing bid, or do rates/oil keep Mag7 and SOX soft through the cash open?

Positioning

AI capex durability — financing cleared at scale; no hyperscaler guide-down. SoftBank’s ~$11.1B OpenAI HY is now issued (world’s largest HY corporate on record per Reuters) — allocator access for the Oct 1 tranche, not an offtake print. BlackRock/IFM exclusive talks on Stack Asia up to ~$25B put another large Asia DC ownership process on tape (unsigned). GS’s Lynam maps hyperscaler IG ~$250bn/’26 → ~$400bn/’27 plus ~$300bn DC/chip project finance in 2027 against still-open IG absorb; SemiAnalysis ClusterMAX 3.0 still sees near-term GPU-hour backwardation. Theme falsifier (top-four sequential capex cut / inference cost killing new build) unmet.

Inference margin inversion — China price hikes vs U.S. list cuts; cache math bites realized P&L. DeepSeek’s ARR ~$1B was partly driven by raising model prices 2.3–4.5× — opposite direction from recent U.S. frontier list cuts already in the archive; China and U.S. lab pricing are not the same market. SemiAnalysis’s endpoint teaser (~75% vs ~99% cache-hit roughly doubling replay cost) weakens the idea that list/serving math alone captures realized inference P&L. No consecutive lab gross-margin decline disclosed.
