OpenAI's run-rate reset and a week of chip dealmaking (2026-10-09)

OpenAI's run-rate reset and a week of chip dealmaking (2026-10-09)

Sources: The Information RSS 2026-10-08/09 (ARR snafu, ~$50B ARR, d-Matrix, Eliyan, Firmus, Amazon/Entergy, Manus); Last Week in AI #346; X home feed (market and chip posts). Raw: ARR, d-Matrix, Eliyan.

TL;DR. OpenAI told investors its annualized revenue was near $50B at end of September, about $20B below widely circulated reports of $70B. Run-rate grew 77% from July (per a post summarizing the report). The FT report moved markets: the Nasdaq 100 fell 1.4% (worst day in seven weeks) and the Philadelphia Semiconductor Index fell 3.4%, with Nvidia, CoreWeave, Nebius and Cerebras down. The Information's own column calls monthly-times-12 run-rates a poor metric. The same week, hardware money kept moving: Nvidia plans to invest in inference-chip rival d-Matrix, pulling challengers into its ecosystem; chiplet-interconnect startup Eliyan (valued at $1B in July) received a takeover bid and may seek about $3B after early talks with Arm; Nvidia-backed Firmus Grid scrapped a ~$5B Australian IPO at a $30B+ valuation, citing volatility; Entergy told Amazon it would curtail AWS's Mississippi data centers at peak demand, forcing a rewiring.

Key points

  • Revenue quality now moves the chip trade. A metric correction at one lab hit the whole semiconductor index. Infrastructure plans are priced on frontier-lab revenue, and that number is softer than assumed.
  • Nvidia's playbook is partnership with challengers. Investing in d-Matrix follows its pattern of making rivals compatible with its stack while it gains inference share. Eliyan's interest shows die-to-die interconnect (how chiplets talk) is where packaging value is moving. See compute economics and memory hierarchy.
  • Power is a hard constraint, not a cost line. A utility warning a hyperscaler it would be cut off at peak is new. California passed seven data-center laws the same week (operators cover their own grid costs and disclose resource use).
  • Other money: Manus raised over $500M (led by Boyu Capital) after Beijing blocked Meta's $2B acquisition; ElevenLabs doubled to $22B via a $300M tender; Waymo closed a $5B term loan with no parent guarantee; Arena raised $200M at $3.1B; Samsung guided to a record Q3 on memory pricing.
