OpenAI is in a WSJ Glass Imaging story that the company has not confirmed. Last verified September 15, 2026. Window: 14–15 September 2026. Not a live feed.

Temporal: August talks, company close
The Series E memo is the canonical event page. February was $300 million at $5 billion. August 18 Bloomberg talks were about $500 million at ≥$12 billion pre-money. The company print is $550 million at $12.55 billion. Pre vs post was not labeled. Named customers include OpenAI — the same OpenAI in the Glass Imaging report, on a different fact (usage vs M&A).
Cornelis: dollars without a cap table
IAG is the only named lead. Do not invent a series letter. Do not add Qualcomm to the round.
Glass Imaging: report, not a filing
Use the reported-deal memo. Compare confirmation standard with Hugging Face (agreed, Huang-named price, 8-K) — not the same.
Robocurve (roundup)
$10 million seed, Sep 14. Initialized Capital led. Notable Capital, Decasonic, Y Combinator, Halcyon Futures participated (RuntimeWire, citing the founder). Delaware public-benefit corp. Open-source Inspect Robots. No revenue. 97,000 package installs is a distribution metric. Below the standalone bar.

- Vinyl Bar $5.5 million pre-seed — too small.
- Dangote refinery IPO — not a VC event.
- Temporal ARR dollars — still missing.
