Trade Secrets: Dailies 09.29.2026

US Stocks open mixed to flat as two AI development shocks land simultaneously — OpenAI paused training on its most advanced models for the second time in three months on safety grounds, and Anthropic's leaked IPO prospectus revealed a $42 billion 2025 net loss, $518 billion in computing obligations, and customer concentration so tight that nearly a quarter of revenue came from just two customers — even as CarMax's extraordinary earnings beat and Nvidia's record buyback attempt to hold the tape together ahead of Wednesday's Micron earnings and Thursday's PCE inflation print.

S&P 500 futures were 0.2% higher at 7:59 a.m. ET and Nasdaq 100 futures rose 0.4% to 30,645 — a modest recovery from overnight lows after the AI safety pair-shock hit chip names hard in Asian trade. The Dow fell 0.34% and the S&P 500 slipped 0.03% in early Tuesday trading as the Nasdaq Composite gained 0.2%, reflecting the same tech-versus-cyclical divergence that has defined September. US stocks have remained range-bound for 42 consecutive sessions without a 1%-plus down day — the longest such streak since 2025 — a compression of volatility that analysts say reflects a market caught between genuine AI demand strength and the structural headwinds of 5.23% 10-year yields and $96–$100 oil.
Anthropic's IPO prospectus leaked to Reuters Monday, revealing the full financial picture ahead of a post-November-midterms debut targeting a $2 trillion-plus valuation. The headline figures: 2025 revenue of $4.6 billion (up 12-fold year-on-year), Q2 2026 revenue of $11.5 billion, a 2025 net loss of $42 billion (including a large non-cash charge), an operating loss of $8.06 billion (widening from $2.98 billion in 2024), $7.33 billion spent on compute and infrastructure in 2025 alone — three times its 2024 bill — and $518 billion in total cloud, compute, and data center obligations ahead. Almost 25% of revenue came from just two customers. A company researcher resigned this month warning of AI's existential risks, a disclosure that must appear in the prospectus. Goldman Sachs separately calculated that AI hyperscalers collectively need $300 billion in AI revenue over the coming years to cover their capex spending — and that current revenues remain below that threshold.
OpenAI shelved the release of its next major ChatGPT model and paused training on its most advanced frontier reinforcement-learning runs following a security incident involving an internal research model — the company's second training pause in three months. The combined impact of the Anthropic prospectus and the OpenAI pause pushed Arm Holdings down 8.70% and Intel down 5.67% in Monday's session, with the AI safety debate that began with Amodei, Altman, and Musk's September 14 weekend commentary now producing the most sustained multi-week headwind for chip hardware names of the entire year. Nvidia rose on its $150 billion buyback expansion even as the broader AI complex fell, underscoring the stock's unique position as both the sector's largest hardware beneficiary and its most shareholder-friendly capital return vehicle.
CarMax (KMX) delivered Tuesday's most compelling non-AI earnings story, with Q2 EPS of $1.16 versus the $0.75 consensus — a 55% beat — and revenue of $7.9 billion, a significant upside surprise that sent the used-auto dealer's shares higher and provided a positive read on the consumer's ability to absorb higher borrowing costs even with auto loan rates above 8%. The result suggests the inventory normalization cycle that weighed on CarMax through 2024 has fully resolved. Carnival Corporation (CCL) also reported before the open with an estimated EPS of $1.35.
August JOLTS job openings print at 10:00 a.m. ET alongside the Conference Board's September Consumer Confidence Index — estimated at 89.2, a further decline from August's already-depressed reading. University of Michigan final September consumer sentiment sits at 48.1 with households expecting inflation of 4.6% over the next year, reflecting the entrenched squeeze from Iran-driven energy costs. The FHFA home price index for July and Case-Shiller 20-city index for July both print at 9:00 a.m. ET. Chicago Fed's Austan Goolsbee speaks at 1:00 p.m. ET and New York Fed's John Williams speaks at 2:00 p.m. ET — the day's Fed communication risk. October rate hike odds remain near 70% per CME FedWatch.
Japan's Nikkei 225 fell 396 points to 65,481 on Tuesday, led by refinery and power-related stocks most directly exposed to oil price re-escalation, with the index extending Monday's losses as the 10-year Treasury yield closed at its highest since the initial US attack on Iran began February 28. South Korea's KOSPI dropped 0.6% to 7,020 as technology heavyweights pulled the index lower on rising yields and the OpenAI pause. The Shanghai Composite rose 6 points to 3,830 — a rare mainland positive outlier in a generally weak regional session. Hong Kong's Hang Seng fell 118 points to 24,523. Gold rose 0.5% after Monday's slump to around $4,352 an ounce. European markets bucked the downtrend modestly — the Stoxx 600 was up 0.46% and the FTSE 100 gained 0.37% in early London trade — as European chip stocks surged on the Anthropic $518 billion compute commitment figure, reading the prospectus as demand validation for AI infrastructure regardless of the company's losses.
