Contested figures, disagreement preserved
Anthropic valuation ?
| Figure | Where |
|---|---|
| $965B ← used in this issue | Multiple sources, internally consistent with the $65B Series H and $47B |
| $1.75–1.8T | One Yahoo Finance report; appears to be contamination from SpaceX's ~$1.75T figure |
| $380B | One IPO-tracker source, materially below every other estimate |
Resolution: $965B paired with $47B run-rate is the only combination consistent across independent sources and with the reported Series H. Used throughout, marked ?.
Microsoft 2026 capex ?
$110–120B (most sources) vs ~$190B (broader definition including leases and other commitments). Both appear defensible under different definitions. The narrower figure is used; the wider one is noted.
Microsoft share performance ?
−21.4% (H1, State Street) · ~−12% YTD (other sources) · −25% in Q1 alone · +16% during the July 28th–31st earnings week. These describe different windows and are not mutually exclusive. Direction is reliable; precise level is not.
Kimi K3 open-weight release date ?
July 17th vs July 26th. availability on July 16th is consistent across sources.
ARC-AGI-3 leadership ?
Anthropic claims Opus 5 scores 3× the next-best model. Prime Intellect claims its MIT-licensed Prime Agent hits 95.5%, surpassing the human expert baseline. Both cannot be straightforwardly true, likely different harnesses or versions. Unresolved.
Hyperscaler capex total ?
$630B / $690B / $700B / $725B / $805B depending on source and definition ( only vs capex plus leases plus commitments). $725B is the most commonly cited; treated as approximate throughout.
"Pacing the Frontier" signatory count ?
1,134 / 1,178 / "more than 1,200". A moving number, since the statement accepted signatures over time. 1,178 is used as the most frequently cited figure.
