As-of 2026-09-25 (weekly refresh; equities aligned to §A. Missing series are N/A/null. Not investment advice.)

Structured research note on a SemiAnalysis piece (summary + investable mapping)—not a reprint. Defer to the original for detail.

Thesis

SA sees SpaceX ~10GW cumulative by YE2027 as credible: speed-first builds + pricey short contracts. MSFT signed 10GW+ YTD with a near-term gap; ~$100B/GW/yr inference economics → likely largest offtaker. See MSFT, NeoCloud.

Analysis

Economics

Tokenomics/Inference Simulator: frontier API inference can clear ~$100B+/GW/yr revenue vs ~$12B/GW/yr rental cost assumptions. Microsoft with OpenAI model access (and reworked share terms per SA) can monetize similar $/MW without training cost → strong incentive to grab MW fast.

MSFT awakening

10GW signed YTD, >$300B contract value (ex-GPU), mostly late-2027/2028—near-term gap. A 3GW SpaceX deal at ~$50B/GW/yr looks extreme but ~90-day cancel terms cut balance-sheet risk.

Why SpaceX can be fast

Speed over classic take-or-pay quality: China power modules, skip scarce LPTs, onsite gas, parallel labor, retrofit+greenfield. NVDA vendor finance + high short-lead pricing may fund the ramp.

Mapping

Path to ~$300B ARR YE2027 for SpaceX (partial capacity reserved for training). Public: MSFT Azure narrative, NVDA supply/finance, GOOGL already an offtaker.

Implications

Outlook

Track SpaceX GW online, MSFT official large deal, gas/interconnect, NVDA supply/finance terms.
