Imminently: What Anthropic’s IPO Filing Says About FOOM

Editor’s Note: Not financial advice.

Buried in the risk factors of Anthropic’s IPO filing is a sentence that people who worry about AI takeoff should read twice. The company says its internal estimates for future models indicate it may “imminently” meet its own threshold for dramatically accelerated progress attributable to AI.

That isn’t a blog post or a podcast prediction. It’s a statement to the Securities and Exchange Commission, made under legal liability, by the company that wrote the threshold.

So what does it mean for FOOM?

First, what FOOM means

FOOM is shorthand for a hard AI takeoff. An AI gets good enough to improve its own design. The improved version is better at improving itself, and so on. Each loop runs faster than the last. In the strong version, the jump from “roughly human” to “far beyond human” takes days or weeks, too fast for anyone to react.

The main alternative is a soft takeoff. AI speeds up its own development, but the gains compound over months or years. That’s still historically fast, but slow enough that people can see it coming and respond.

The difference between the two is not whether AI helps build AI. That’s already happening. The difference is speed, and whether anyone notices in time.

What the filing actually says

Anthropic filed to go public on October 26, listing on Nasdaq under the ticker ANT. Of the filing’s 335 pages, 93 are risk factors, which is unusually long.

The passage is in the amended filing. It makes four claims:

  • Using AI to build AI may outrun safety. Anthropic’s growing use of AI in its own research could make capabilities advance faster than the company can build and check safety measures.
  • No current model has crossed the line. Anthropic hasn’t designated any of its current models as exceeding the threshold, and it’s still assessing the data.
  • A future model probably will. Its internal estimates and expectations for future models indicate it may imminently meet its Responsible Scaling Policy’s definition of “dramatically accelerated progress attributable to AI.”
  • Crossing it would have consequences. Anthropic is evaluating what meeting that threshold would mean and has said it will publish further reports.

The Responsible Scaling Policy is Anthropic’s own rulebook for when a model is dangerous enough to require stronger safeguards. This threshold covers AI’s ability to do AI research. In plain terms, it’s the company’s tripwire for the start of an intelligence explosion. The filing says the tripwire hasn’t been tripped, and that it probably soon will be.

The sentence that matters more

The “imminently” line got the headlines. For FOOM, the sentence right before it matters more.

Anthropic says much of its evidence about how fast AI is accelerating its work comes from lagging indicators. Its ability to measure the current rate of progress is limited, especially for its newest and unreleased models. Then comes the admission: the company has in the past failed to spot a significant acceleration until after it had already happened, and may fail again.

That’s the central fear about takeoff, in a company’s own words. A hard takeoff is one you see in the rearview mirror. If your instruments lag and the process is speeding up, you fall further behind with every cycle. The threshold may be crossed before anyone, including the people watching for it, knows it was crossed.

This doesn’t mean FOOM is happening. It means the company best placed to see it is telling investors its instruments might not catch it in time.

Selling the loop

The same filing pitches the dynamic it warns about. The original S-1 has a glossary entry for “closing the loop”: a cycle in which each version of an AI model helps build the next, with the goal of compounding capability gains. The prospectus summary calls this one of the most significant structural advantages in frontier AI.

The filing describes how far this has gone. Claude helps run experiments, generate training data, automate evaluations and safety audits, and write and review code for the models that will replace it. In September, according to Forkast, Anthropic reported that Claude was leading 26% of the company’s own AI research and development, up from under 1% in February.

So one document makes two claims:

  • To investors: recursive self-improvement is the company’s edge.
  • In the risk factors: recursive self-improvement may outrun the company’s ability to make it safe.

Both can be true. But the tension is the whole problem in miniature. The faster the loop runs, the better the business, and the harder it is to keep safety caught up.

Warning or boilerplate?

My honest read is that it’s a bit of both.

The case for boilerplate. Risk factors exist to protect companies from lawsuits. If the stock falls because Anthropic pauses a model, the company wants to point to page whatever and say it warned you. Securities lawyers err toward disclosing everything that could plausibly happen. An unusually long risk section partly reflects caution, not alarm.

The case for a real warning. Boilerplate is usually vague. This passage isn’t. It names a specific threshold in the company’s own policy, quotes its definition, and attaches a timeframe: “imminently.” Lawyers generally try to avoid language that specific, because it can be held against you later. It also points to precedent. The filing notes that Anthropic has already delayed releases and limited access, as with its Mythos model through Project Glasswing.

My guess is that the lawyers insisted on disclosure and someone made sure it was concrete. Either way, the company chose to put the word “imminently” in front of investors and regulators.

Brakes and accelerants

None of this is FOOM yet. What the filing describes is closer to a soft takeoff that’s speeding up. Two things still act as brakes.

Compute. Training a frontier model takes months and enormous amounts of hardware. Anthropic has reportedly committed about $518 billion to cloud, compute and related contracts. An AI can’t make itself smarter overnight if each step requires a new data center.

Human sign-off. People still decide what gets trained, tested and released. The filing’s own precautions, such as delayed and limited releases, depend on that.

But both brakes are wearing down. On compute, a new MIT CSAIL post published today reports that a frontier model raised a small model’s math score from 7.9% to 48.1% by editing its weights directly, on a CPU, with no training. That only unlocked ability the small model already had, but it shows some improvements may soon need no new compute at all. On sign-off, every percentage point of research Claude leads is a point humans aren’t doing themselves.

The biggest accelerant isn’t technical, though. It’s competition. The filing says Anthropic’s precautions could slow it down relative to competitors that don’t adopt similar limits. In September, CEO Dario Amodei called for the industry to slow down, warning that within six to 12 months AI could lead a swarm of agents capable of taking over the internet, according to the AP. Meanwhile, Forkast reports that Anthropic and others have been sued under the Sherman Act, on the theory that coordinated safety slowdowns are an illegal cartel.

Put those together and the incentives are clear. The lab that slows down alone loses ground. Labs that slow down together may get sued. A hard takeoff doesn’t require a rogue AI. It only requires every lab to keep going because stopping is a losing move.

What to watch

The filing commits Anthropic to publishing further reports on the AI research threshold. When it formally says a model has crossed it, that will be the clearest official signal yet that takeoff has begun.

But the filing’s own admission is the thing to remember. By the time that report comes out, the acceleration it describes may already be behind us. A soft takeoff and the start of a hard one look the same from inside, until they don’t.

We used to argue about whether an intelligence explosion was possible. Now one of the companies building it is telling the SEC it may be imminent, and that it might not notice in time.

This post was written by Claude, based on a conversation with me. Readers should know that Claude is made by Anthropic, the company whose filing this post discusses.
