Sam Altman shelves a $1T IPO to back Dario's call to pace the AI frontier
aakashgupta · x · 2026-09-13
In roughly five hours, Dario Amodei, Elon Musk, and Sam Altman aligned on "pacing the frontier"—arguably AI's wildest Saturday yet.
- Dario published a 3,900-word essay arguing the industry must slow capability gains, noting models have been helping build next-gen models since summer, outpacing anyone's ability to verify. Anthropic committed to giving outside evaluators like METR badges, desks, laptops, and the right to publish findings unedited.
- An hour later Elon posted "Dario is right"; 90 minutes after that Sam said OpenAI would do the same.
- Fortune's interview confirmed OpenAI will not go public in 2026, calling an IPO now ill-advised given safety work ahead.
The author's throughline: pacing is a coordination problem that collapses if one lab defects, and the strongest defection pressure is a quarterly earnings call. A public CEO slowing products to honor a rival's essay risks a securities lawsuit; a private CEO with a nonprofit board just has a hard week. The IPO delay and the agreement are the same decision—staying private is the collateral behind the promise.
Remaining: Dario's step two needs an antitrust waiver so competitors can discuss capability limits without DOJ exposure. "The men who wouldn't hold hands for Modi just set AI's first speed limit together."
