Neocloud Capital Day: Nscale Sprints Toward a $35B IPO; CoreWeave Locks In 2.875%
Today in one sentence: Nscale filed for a NYSE IPO targeting up to $35B with a $44.6B Anthropic contract in hand, and CoreWeave priced an upsized $3.7B convertible at just 2.875% — the neocloud capital race is accelerating; memory stocks melted up into quad-witching, with MU closing above $1,000 for the first time.

1. Nscale files for a NYSE IPO: the prospectus is the industry's first public physical exam
What happened. On 9/18, Nvidia-backed British AI cloud/data center company Nscale publicly filed for a NYSE listing (SiliconANGLE relaying the prospectus; Reuters/FT/WSJ/Bloomberg all confirmed): it aims to raise up to ~$3B (per Bloomberg) at a targeted valuation reportedly as high as ~$35B — a ~2.4x re-rating in six months from its $14.6B March private mark. Key prospectus numbers: H1 2026 revenue of $140.6M (+1,250% YoY); net loss of $1.02B (nearly 3x YoY); last month's $44.6B infrastructure contract with Anthropic (~460MW at the Monarch campus in West Virginia, microgrid-powered); Figure AI committed to renting up to 100,000 GPUs (Nscale taking a stake in Figure); plus a multibillion GPU hosting agreement with Microsoft. It has 25,000 GPUs deployed and 461,000 "active and contracted," claims a "clear expansion path to 8GW+," recently issued $3.1B of convertible notes (at least $1B taken by Nvidia), and has raised $4.6B+ of debt YTD.
Why it matters. Three readings: ① Price calibration — $44.6B/460MW ≈ ~$97M of full-cycle contract value per MW, which cross-checks against CRWV's $40M/MW annualized short-term contracts: long-term lockups are cheap, spot/short-term is expensive, and the spread itself prices scarcity. ② Capital structure — Nvidia graduates from supplier to creditor (≥$1B convert), one more rung in the circular-financing stack. ③ Valuation yardstick — if the $14.6B→$35B re-rating lands in public markets, CRWV/NBIS get their first same-generation comp; if it doesn't, it's a stress test of the sector's liquidity.
Investment implications. For CRWV/NBIS: more valuation anchors are good, but AI-infra paper supply is arriving in the same week — whether the marginal buyer is thick enough is the core question. The prospectus's 18x gap between "25k deployed vs 461k contracted" is the industry's capacity leverage in miniature: fulfillment needs CapEx, CapEx needs financing — the chain is intact but every link is getting more expensive. Falsification: IPO priced well below the $35B target or postponed, or GPU depreciation-cycle assumptions publicly challenged by sell-side.
2. UPDATE — CoreWeave's convert prices at 2.875%, upsized to $3.7B: the cost-of-capital question gets its answer
What happened. (UPDATE — the increment on yesterday's story) On 9/18 CoreWeave priced its convertible notes: upsized from $3.0B to $3.7B, plus a $500M option for initial purchasers (up to $4.2B); coupon 2.875% (due April 1, 2033, settling 9/22); initial conversion price $97.85, a 22.5% premium to the 9/17 close of $79.88; $498.8M spent on capped calls with a $199.70 cap (150% premium); net proceeds ~$3.64B (terms per the pricing release; structure per the SEC 8-K exhibit). The stock closed +1.85% at $81.36 on 9/18.
Why it matters. Yesterday's open question — "the coupon is the direct read on neocloud cost of capital" — now has its answer: 2.875% is far below CoreWeave's existing straight debt at 8.5–9.75% and close to its older converts issued in 2024–25 at 1.75%. In other words, credit markets still fund CoreWeave on "high-vol growth" terms, not "distressed credit" terms — demand was strong enough to upsize by $700M. $40M/MW of pricing power × 2.875% funding cost: that spread is currently the hardest data point supporting the GPU-leasing ROIC narrative.
Investment implications. Financing-cost fears are temporarily resolved, but the total quantity of dilution hasn't changed: up to $4.2B of converts plus a 35M-share ATM still overhang the stock — only the price and pace changed. Watch: the 9/22 settlement and whether the $500M option is exercised; whether the stock can hold near the $97.85 conversion price — the $199.70 capped-call cap implies structural hedging flows in the $97.85–$199.70 band. Falsification: a deep break below the conversion price, or materially wider spreads on the next raise.
