AI

The Slowdown CEO and the Ship Button

By Omar aka Crypt0 · Sep 19, 2026

On September 12, Anthropic CEO Dario Amodei published a 3,800 word essay asking the AI industry to slow down. "We must slow the pace at which we improve the capabilities of AI models," he wrote, describing swarms of AI agents spreading across the internet faster than human control could follow. Sam Altman and Elon Musk voiced support. Seven days later, Reuters reported that Anthropic is weighing the release of a new model to counter OpenAI's momentum, with sources pointing to competitive pressure building ahead of an expected IPO.

The pressure has a number. OpenAI released GPT-6 Astra on September 3, touting gains in computer use, software engineering, cybersecurity and professional work, and enterprise buyers responded fast. Astra captured about 13 percent of enterprise AI spending tracked by corporate expense platform Ramp, compared with about 8 percent for Anthropic's Claude Fable. On OpenRouter, the platform that routes developer traffic across models, users spent more on OpenAI models than Anthropic models last week, the first time OpenAI has led that measure in more than two and a half years. Some investors told Reuters they are reassessing Anthropic's standing as the leading enterprise AI provider.

And yet the revenue scoreboard still favors Anthropic by a wide margin. The company's annualized revenue run rate topped $65 billion by the end of July, up from about $9 billion at the end of 2025. OpenAI's run rate passed $40 billion in July. Anthropic is projecting 2028 revenue of roughly $190 billion to $200 billion. Investors who expect to back both companies' public listings told Reuters that unseating an entrenched enterprise vendor takes years, so Astra's early sprint changes little about Anthropic's position in large accounts.

The deeper challenge sits on a different flank entirely. Investors told Reuters that open source and open weight models keep gaining ground, lowering token costs and letting companies build more of their own AI infrastructure instead of renting it from the leading commercial labs. That shift pressures the economics of the whole commercial model business, widening the competitive threat well beyond the Anthropic and OpenAI duel. Meta, one of Anthropic's largest customers, is looking to reduce its use of Anthropic models as it builds more AI capability internally. Rising interest rates are making investors focus harder on when profits arrive.

Then there is the calendar. Anthropic could push its IPO to after the November midterm elections, with marketing expected to begin in mid October at the earliest. OpenAI has eased pressure on the race to public markets: Altman confirmed Saturday the company will stay private through 2026, citing AI safety concerns. Anthropic declined to comment on the Reuters report, though one source said the company is evaluating the safety of its next model as part of its release deliberations.

For anyone choosing AI tools, building on them, or allocating capital around them, the message is unusually clear. Safety pledges and shipping schedules are now the same conversation, debated in public, in real time. The labs that handle that tension with honest safety work and credible releases are the ones that will earn the enterprise workloads that matter. Watch what ships next, and watch the safety reports that ship with it; that pairing tells you who is serious.
