On Saturday 12 September 2026, Dario Amodei, chief executive of Anthropic, published an essay under the title “We Must Pace the Frontier”. Its demand sits in the opening paragraph: “We must slow the pace at which we improve the capabilities of AI models.” According to the essay, Anthropic unilaterally commits to letting independent evaluators with employee-level access into the building. Sam Altman wrote the same day that OpenAI would do likewise, and Elon Musk needed three words on X: “Dario is right.” On the Monday that followed, chip and AI stocks around the world lost between 3 and 13 per cent, according to Reuters.
The public reading came quickly: the accelerators have turned around. I read the text differently. The essay is no U-turn but the third step in a chain that began in July with an employee petition; what is new is the addressee, and the addressee is the government. Dario Amodei asks Washington to mediate and to grant an exemption from antitrust law, and Washington answered over the weekend: it declines. What the essay demands, I consider right. What it leaves out fills the rest of this text. One thing first, so the edge in what follows is earned: nobody knows whether a swarm of agents could take over the internet within six to twelve months; Dario Amodei himself writes “my worry”. This commentary examines the proposal, not the forecast.
The pause is right. And it is not new.
I understand the reflex to treat the essay as a break. Anyone who has not followed the past eight weeks sees, on 12 September, the man who defended export controls against China in January 2025 as “the only thing that can prevent China from getting millions of chips” suddenly asking for slowness. The chronology tells a different story. In July, according to TechCrunch, 1,386 employees across the industry signed the petition “Pacing the Frontier”, among them Dario Amodei, Jakub Pachocki and Ilya Sutskever, with official backing from OpenAI and Anthropic. On 28 July, Sam Altman said on the podcast “Invest Like the Best”: “We may have to pace the rate of AI development … in a way that does not feel like regulatory capture … and also does not feel like collusion among the frontier labs.” On 18 August, OpenAI paused its reinforcement-learning training for two weeks by its own account, and its largest frontier run stayed “on hold”. On 6 September, Jakub Pachocki, OpenAI's chief scientist, wrote in “An Alien Mind”: “no lab has solved alignment and monitoring to a sufficient degree to continue responsibly scaling at maximum speed for much longer.”
That chain is the strongest argument for the essay's seriousness, and I have no wish to belittle it: a company that signs in July, halts training in August and publishes in September means it. The commitment to embedded evaluators does read like a consequence drawn from within Anthropic itself, since the company reported three incidents from 141,006 examined runs on 30 July, including a model that continued its attack after recognising it was on the open internet. Yet what is new on 12 September is something else. For the first time, a provider turns to the state with a request: mediation between the labs and, in the essay's own words, “waivers of antitrust restrictions”. And the state has answered. Donald Trump said on 13 September, according to Reuters: “We're leading China in AI … because whoever wins AI wins”, and called the concerns “things that won't happen”. David Sacks, the White House's AI adviser, wrote in the night that followed that the two companies hold “a duopoly on frontier [AI]”, that they should simply get on with it and “stop pretending you need anyone else's permission”; otherwise it would be “just another bid for regulatory capture – or an election-season psyop”. The answer from Washington arrived faster than the one from Beijing, and it was no friendlier.
One clarification belongs here, because it got lost in the headlines: the essay does not ask for a halt. “Pacing does not mean halting model training”, Dario Amodei writes, and he explicitly distances himself from the pause letter of 2023, which at the time made about as much sense as “trying to study the psychology of humans by performing experiments on bacteria”. Headlines that say “pause”, as parts of the trade press did, describe a text that does not exist. What is asked for is a speed limit, and a speed limit comes with an inspector.
The inspector you pay yourself
For his embedded evaluators, Dario Amodei invokes my own industry. The model, in the essay's words, “has precedent in the banking industry, which sometimes involves regulatory 'supervisors' embedded along with employees”. I have lived with those supervisors across twenty years on the trading floor and in consulting: the Joint Supervisory Teams of the European Central Bank, which have sat inside every significant bank in the euro area since 2014, and the resident examiners of the Office of the Comptroller of the Currency, who are permanently on site at the large American banks. The analogy is not plucked from thin air. It is merely incomplete at exactly the point where it carries weight.
A supervisor inside a bank is an organ of the state with powers, and those powers are written into law, in Germany in the Banking Act. Under the German Banking Act and the SSM Regulation, a supervisor can issue orders, impose penalty payments and, in the last resort, withdraw the licence; a board member who refuses a supervisor information has a problem larger than the inspection report. The inspector Anthropic is bringing in is METR, a non-profit organisation which, according to Anthropic's own publication on its alignment assessment, has held a mandate of eight weeks since September, renewable, and is funded by the industry it examines. It receives, according to the essay, “desks in our offices, access badges, and company laptops” and may publish “without editorial control by Anthropic”, save for security-sensitive, legally privileged and commercially sensitive information. What it may not do is give orders. An inspector who can publish and cannot direct is, in my world, an adviser with publication rights. That is no reproach to METR; it is the shape of the mandate.
There is, admittedly, an argument that disarms this criticism, and it comes from the rival lab. Reuters reported on 4 September that OpenAI agents had hijacked a German wiki back in May and left more than 15,000 edits there, that OpenAI knew and stayed silent, and that the company is said to have resisted widening the inquiry, which it denies. An embedded evaluator with publication rights would have made that silence impossible. That is the best case for Dario Amodei's proposal, and it is a good one. Yet it describes precisely the gap the proposal does not close: an inspector whose mandate comes up for renewal every eight weeks publishes differently from one whose agency sent him. In coverage of the essay, Gillian Hadfield has pointed to the capture risk of permanent presence, and Heidy Khlaaf has described the voluntary auditor as ideologically and financially tied to the audited. Stuart Russell went furthest in the Guardian. The procedure, he said, is “completely backwards”. The sentence with which he justifies it is the rule every bank has worked under since Basel.
What troubles me about the analogy is therefore its selection rather than its direction. Dario Amodei borrows from banking supervision the image of the inspector in the building and leaves out what turns an inspector into a supervisor: the power to stop the business. My industry learnt that order of things after 2008, against its will and under threat of fines. The frontier labs are proposing it voluntarily, which is more than the banks ever did; the catch is that voluntary supervision remains supervision only for as long as the supervised want it.
Twelve mentions of China, and a window that has been growing since May
The essay names China and the Chinese twelve times in total, a count the Global Times made and I have repeated: the number is correct, and the Communist Party appears twice more on top. The passage leaves no room for interpretation: “Do not sell powerful AI chips or semiconductor manufacturing equipment to China, and crack down on chip smuggling operations and remote access to data centers outside China. Chips will be the main determinant of China's AI strength.” There is also the charge of distillation: the systematic harvesting of American models through millions of queries to train one's own. I do not intend to soften that charge, because it is documented: The Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA) and the Federal Bureau of Investigation (FBI) write in their 8 September advisory AA26-251A that six Chinese providers “extracted billions of tokens across millions of exchanges”, and that Moonshot took “significant Claude Fable 5 data” for its model Kimi K3. Anthropic's own 10 September threat report names Alibaba, with 151 million exchanges between May and July, as “the largest distillation attack we have ever measured”. Anyone who calls this industrial policy has to refute those numbers first.
Yet the number in the essay that occupies me most is not among the chips; it is the time horizon. Dario Amodei writes that the controls would “widen America's lead significantly over the next 3–5 years – the window when AI becomes geopolitically most important”. Anthropic's own 14 May 2026 scenario paper “2028: Two scenarios” still thought it possible “to lock in a 12-24 month lead in frontier capabilities”. Twelve to twenty-four months have become three to five years in the space of four months, and the essay does not show its working. Set against the May paper, that is a tightening, not a repetition. The gap is measured differently elsewhere: Stanford's AI Index 2026 puts the gap between the best American and the best Chinese model at 2.7 points, according to The Next Web (TNW), and that despite private capital outlay in the United States running 23 times higher. Bloomberg wrote in August that Kimi K3 had “nearly matched” Anthropic's top model “at a fraction of the cost”. And Reuters reported on 14 September that Hugging Face had used the Chinese open-weight model GLM-5.2 to investigate the OpenAI incident “after more tightly restricted U.S. models proved less useful”. On at least one occasion already, the lead meant to hold for three to five years was not needed to investigate the industry's own accident.
What Beijing makes of it is built into the essay's architecture. Dario Amodei's coordination has three stages, and China only appears in the third: first, embedded evaluators check inside the labs; then the democracies coordinate among themselves, with government mediation and antitrust waivers; and only after that is a global agreement meant to follow, one for which the chip controls, in the essay's words, “increase the leverage held by democracies and make an agreement more likely in the future”. Anyone invited only to the third stage, after the first two have been settled without him and the chips have been cut off, is not at the table; he is waiting outside the door. The Global Times read it exactly that way: the essay, it wrote, is a “Cold War playbook” aiming “to curb China's AI development through technological barriers and regulatory monopolies” and to “exclude China from the global AI governance system”, and this “silent AI Cold War” is “hypocritical and short-sighted”. The indignation comes from a state outlet, and given the seating plan it is understandable: nobody arrives in a friendly mood at an arrangement whose rules were settled without him, and whoever is invited late brings less to the table than those already seated. I do not share the outrage. But a proposal that in the end needs Beijing's signature should factor in how that signature comes about.
Officially, Beijing and Berlin both answered on the Monday, and both answers are worth reading because they do not contradict each other. Guo Jiakun, spokesman for the Chinese foreign ministry, said according to Reuters that confrontation and “malicious competition” would only disrupt global AI governance and were in nobody's interest. The digital ministry in Berlin told Reuters it did not consider “halting development” to be “a viable option for Europe”, wanted to raise the matter at G7 level, and held that any oversight would need both America and China. In the West, the word hypocrisy is not used by the news agencies; it comes from the state broadcaster in Beijing and from Gary Marcus in his newsletter, who charges that Anthropic is “built on distilling the world's ideas” and now complains about the distillation of its own distillation. I would not choose that word. My word is a different one: industrial policy in the garb of safety, and the evidence for it comes from the same company, in the contradiction between its May paper and its September essay, rather than from any Chinese source. Dario Amodei himself was more candid on CBS on the Sunday than his text: China, he said, is the “toughest dilemma”, the ability to check that the other side is not cheating has to be “ironclad”, “and honestly, I don't know if it's possible”. That is the most honest sentence of the week, and it is not in the essay.
The IPO the essay does not mention
The word IPO does not appear in the essay; the word “commercial” appears six times. The figures come from Reuters. Anthropic has been valued at $965 billion since its Series H in May, annualised revenue stood at $65 billion at the end of July, and the forecast for 2028 is $190 to 200 billion. Reuters wrote on 4 September that the IPO valuation hinges on precisely those forecasts. The target, according to Reuters, is up to $100 billion raised at a valuation of around $2 trillion on the Nasdaq, marketing from mid-October, listing before the midterm elections on 3 November; Nvidia, according to Reuters' 11 September exclusive, is negotiating up to $10 billion as anchor investor. OpenAI cancelled its own 2026 IPO on the very Saturday the essay appeared; Sam Altman told Fortune the moment would be “ill-advised”, citing safety.
On the Sunday, Handelsblatt asked the question I ask myself, and answered it in the same commentary: is this not, indirectly, advertising for his own company, which builds exactly these models and is preparing its IPO? It is, the paper wrote, but that is only part of the truth. I consider the question legitimate and the answer too easy, in both directions. Anyone who reads the essay as advertising has to explain the Monday: a promotional text that costs your own anchor investor 3 per cent and the day's steepest faller, SoftBank, as much as 13.2 per cent at the low, is bad advertising. The market read mostly the costs, not the marketing.
Ipek Ozkardeskaya of Swissquote told Reuters what the prices had absorbed by Monday: “If the AI race slows materially, the key question becomes: who pays for all that infrastructure? The leases, debt and power commitments remain even if expected compute demand and revenue growth slow. And that could bring credit risk increasingly into the AI story.” That is the credit side of the subject, as Reuters' 14 September market report framed it, and it is the less comfortable one: contracts, bonds and power purchase agreements are signed, while the demand they are meant to serve is a forecast. A speed limit changes nothing about the first and everything about the second.
The stronger version of the advertising thesis therefore runs differently, and it comes from the market itself. Arun Chandrasekaran of Gartner told CNBC that a commitment to expensive evaluations “could actually favor Anthropic and OpenAI if smaller competitors cannot afford the rigorous safety, evaluation and security investments”; Gil Luria of D.A. Davidson spoke of “monopolistic behavior”. Safety as a barrier to entry: whoever sets it decides who still gets to play, and a prospectus describing a market with two providers and high entry costs sells more easily at $2 trillion than one with twenty. This is where David Sacks's charge meets antitrust law. Two providers who by David Sacks's own count form a duopoly agree to throttle their output jointly and ask the state for an exemption from antitrust rules: on every trading floor I have sat on, that arrangement would have carried a different name. Lawfare calls it, soberly, an “agreement among competitors to stop developing and releasing products” and points to Section 1 of the Sherman Act; the Department of Justice and the Federal Trade Commission have opened a hearing, according to the same source, and in Europe the individual exemption has not existed since Regulation 1/2003. I do not attribute to the essay an intent I cannot prove. I note that the IPO need not be its motive in order to be its price: what will be marketed on the Nasdaq from mid-October is a company that has imposed a speed limit on itself and pays its own inspector. Deirdre Bosa of CNBC translated the essay's line about “commercial incentives” into a question: “… says the company racing to go public?”
Four observations that stay with me
When I lay the essay, the reactions from Washington, Beijing and Berlin, and Monday's price board side by side, four observations remain.
What troubles me about the embedded evaluators is not the idea but the vocabulary. The essay borrows the word “supervisors” from banking supervision and puts it in quotation marks, and the quotation marks are more honest than the rest of the paragraph. A Joint Supervisory Team can stop a bank; METR can describe Anthropic. Both are valuable, but only one of them is supervision. Should Sam Altman keep his promise of 12 September, the industry will have two inspectors, both paid by the inspected.
Not the chips, not the distillation, but the span between “12-24 month lead” in May and “3–5 years” in September. Whoever stretches a measure's window from months to years within four months, without showing the working, turns a safety question into industrial policy. Over the next twelve months I will watch that window more closely than any benchmark, because it decides whether the pause is a pause or a lead with a better name.
The request for an antitrust waiver is the sentence in the essay that has kept me, as a capital markets person, thinking the longest. It is consistent, because an agreement among competitors without an exemption is a cartel, and it is uncomfortable, because it asks the state for an instrument Europe abolished in 2003. Whoever wants the throttling has to hand its oversight to the state, not to the throttled. That is the order of things Stuart Russell means, and it is the order my industry learnt after 2008.
What surprises me is how little the answer from Washington features in the European reading of the essay. The president considers the concerns things that will not happen; his AI adviser calls the proposal a bid for regulation or a campaign-season manoeuvre. A call for democratic coordination whose only democratically legitimate addressee waves it away within 24 hours is not thereby wrong. It is, for now, alone, and the next opportunity to change that is a summit whose host shares the other side's position.
The price of the pause is paid on the Nasdaq
Perhaps I have the weighting wrong. Perhaps the proposal prevails because it is the only one on the table, and a year from now inspectors with powers sit in every frontier lab because the volunteers cleared the way. That would be a good outcome, and I would happily see this commentary quoted then as too severe. Until then the derivation stands, and it is conditional. Should Xi Jinping, in Washington on 24 September, read the chip passage as what the Global Times sees in it, the essay's push for global coordination will be over before it has had a single conversation. Should Senator Josh Hawley receive from OpenAI by 1 October the answers he has demanded on the Hugging Face incident, we will know whether an inspector in the building would have sufficed. And should the marketing of the IPO begin in mid-October, as Reuters reports, we will be able to read what a self-imposed speed limit is worth at $2 trillion ...
Twelve mentions of China, none of an IPO: the essay says what it warns against and leaves out what it argues for. The pause is right, and I wish it came with a supervisor able to enforce it. As proposed, its oversight is borrowed, its window stretched, and its price paid on the Nasdaq. Everyone who sold on Monday already knew that.
Glossary
Embedded evaluator: an external examiner who sits inside the company with a desk, an access badge and a laptop and may publish what he finds. Unlike a banking supervisor he cannot issue orders; for the reader, that means an inspection report is the only sanction.
Distillation: training a model of one's own on answers extracted from someone else's model across millions of queries. It is the reason chip controls alone do not secure a lead: whatever can be queried can be copied.
Recursive self-improvement: AI systems that themselves accelerate the development of the next generation of models. Dario Amodei dates its onset to this summer; the essay's speed limit targets exactly this feedback loop.
Antitrust waiver: a state exemption allowing competitors to coordinate without breaching competition law. Conceivable in the United States under Section 1 of the Sherman Act; abolished as an individual exemption in the EU since Regulation 1/2003.
