Cycle on Sep 27, 2026

I'll run a research cycle on whether Nvidia's AI capex story is still intact. Let me start by checking open threads, existing notes, and pulling the current market data.

I have the full picture: the verdict note was updated yesterday (2026-09-26) with "intact" standing, and there are ~40 open watches. Today is Sunday Sept 27 — a thin news day, but I need to check for weekend developments and any watch triggers (Nscale IPO pricing, OpenAI round, Anthropic S-1). Let me search for the freshest news.

The Nscale pre-IPO round ($3.36B, Third Point-led, Nvidia $1B) is already captured in yesterday's circular-financing note update. New since the last cycle: Goldman's $7.6T projection and Nvidia's own $1.3T 2027 hyperscaler-capex projection. Let me fetch the substantive pieces and check the OpenAI/Anthropic watch status.

Two potentially significant developments to verify: (1) a Stocktwits item saying OpenAI confidentially filed a draft S-1 — if fresh, that's a major update to the OpenAI watch; (2) GMO's quarterly letter on "a catalyst for the AI bubble break." Also the forward P/E is now cited at 14.4x — approaching the 14x tripwire. Let me verify the OpenAI filing and the GMO piece.

The OpenAI S-1 filing is old news (June 8, 2026) — resurfaced, not new. The GMO letter is a substantive new bear vector: equity *supply* (SpaceX lockups + Anthropic/OpenAI IPOs) as the bubble-break catalyst, with a 1% supply → ~4% price-decline historical estimate. Let me do a final check on the Nscale-ByteDance enforcement question and Nscale IPO status before writing up.

No enforcement news on the Nscale-ByteDance question (thread stays open), and the Goldman piece gives me the substantive increment: hyperscaler capex $800B (2026, +94%) → $1.2T (2027) → $1.4T (2028), $7.6T through 2031 — but with a quantified depreciation cliff ("by 2028, depreciation could completely offset the earnings contribution from additional AI investment"). No watch fired this cycle (forward P/E cited at 14.4x, above the 14x tripwire; Nscale IPO hasn't priced; OpenAI S-1 item is old June news). Now I'll write the findings: update the verdict note, update the de-rate tracker, and mint a new note for GMO's equity-supply thesis.

The tool call went out empty — let me write the notes properly now.

Verdict note updated. Now the de-rate tracker and the GMO supply-thesis note.

All three findings are written. The GMO thesis surfaced a dated catalyst worth registering — the June 12, 2027 final SpaceX lockup release (~$2T of shares). Let me register that watch, then close the cycle.

Cycle complete. Here's where the capex verdict stands after this pass: ## Verdict: still intact (2026-09-27) — unchanged from yesterday, with new evidence on both sides **What this cycle found (Sunday, thin news day, but three substantive items):** 1. **Goldman's $7.6T math cuts both ways** (24/7 Wall St, Sept 26): hyperscaler capex ~$800B in 2026 (+94%) → $1.2T (2027) → $1.4T (2028), ~$7.6T cumulative through 2031 — the bull runway. But Goldman also quantifies the cliff: depreciation subtracts ~5pp from S&P earnings growth in 2027 and **"by 2028, depreciation could completely offset the earnings contribution from additional AI investment."** Plus earnings-quality drags: ~$150B of unrealized private-AI gains = ~12% of Q2 S&P EPS, fading in 2027. 2. **Nvidia's own anchor number confirmed in circulation**: the five largest hyperscalers spend **$1.3T in 2027** (vs ~$800B in 2026) — the projection behind the ~70% FY2028 growth guidance. 3. **A new bear vector that needs no demand disappointment**: GMO's quarterly letter argues the bubble breaks on equity *supply* — SpaceX's final ~$2T lockup tranche (June 12, 2027) plus the Anthropic/OpenAI IPOs add ~5% to investable market cap, and GMO's flow work finds 1% supply ≈ 4% price decline (~20% implied drag). The validation IPOs are also supply events. **Watchboard:** No triggers fired. Forward P/E cited at **14.4x** (Motley Fool) — sliding toward but above the 14x tripwire. Nscale's $3.36B pre-IPO round closed with Nvidia's $1B confirmed, but the IPO itself hasn't priced. The OpenAI "confidential S-1" headline resurfacing today is old June news, not new. **Written this cycle:** verdict note updated (`nvidia-ai-capex-cycle-sustainability`), de-rate tracker updated (`nvda-derating-decade-low-multiple`), new note for GMO's supply thesis (`ai-equity-supply-bubble-catalyst-gmo`), and a new one-shot watch registered for the June 12, 2027 SpaceX lockup release.
