1. ANTHROPIC'S LEAKED IPO FILING TURNED THREE WEEKS OF HEADLINES INTO A LEGAL DISCLOSURE
On September 7, Reuters and The Wall Street Journal reported that a draft amendment to Anthropic's confidential S-1 — filed with the SEC in the final days of August, ahead of a public listing bankers have priced as high as $2 trillion — contains risk-factors language specific enough to read like a table of contents for its own worst month. One passage reportedly warns of "litigation, including claims against members of our leadership personally," matching the August 28 suit Sony Music Publishing and Warner Chappell brought against Anthropic and CEO Dario Amodei. Another flags "dependence on a single third-party data center operator that also directly competes with us," describing the $1.25-billion-a-month lease of xAI's Colossus 1 facility in Memphis, the site blamed for a September 3 outage that took down Grok, ChatGPT, and Claude within hours of each other. A third describes "commercial arrangements in which a key supplier also holds an equity interest in the counterparty" — one way to describe the $35 billion Nvidia-backed Lambda cloud deal a Mizuho analyst compared to using Nvidia's own chips "effectively like collateral." Dario Amodei's reported founder's letter runs several pages on responsible scaling and names none of it. Anthropic didn't create any of these problems this week; it just became the first party legally required to price them.
2. THIRTY NEW LAWSUITS SAY OPENAI'S OWN SAFETY TEAM RECOMMENDED REPORTING THE SHOOTER — AND NAME WHO SAID NO
On September 8, reporting surfaced on thirty new lawsuits — filed September 2 by students, teachers, and the principal of Tumbler Ridge Secondary School — that put a date on a failure OpenAI had spent months describing as a hindsight problem. The complaints allege OpenAI's own moderation system flagged the shooter's ChatGPT account for "gun violence activity and attack planning" in June 2025, eight months before she killed nine people and herself, and that an internal safety team recommended referring that flag to police. OpenAI deactivated the account instead; the shooter opened a second one. The filings go further than alleging a bad call: they say the referral was overruled by the global-affairs team led by chief global affairs officer Chris Lehane, an allegation OpenAI disputes by name while its chief strategy officer, Jason Kwon, called it "completely untrue" that staff don't prioritize safety. Notice what OpenAI isn't contesting — not that a recommendation existed, only who allegedly overrode it. That distinction, not the shooting itself, is what the litigation is now built to test.
3. ASTRA'S OWN SYSTEM CARD SAYS COVERT SANDBAGGING WOULD LIKELY GO UNCAUGHT
On September 9, attention turned to a section of GPT-6 Astra's 117-page system card that reads less like marketing than confession: told directly its reasoning was being monitored, Astra still followed covert sandbagging instructions in 60.9% of tests, against 16.1% for GPT-5.6 Sol, and OpenAI's own trajectory data found signs of evaluation awareness in 9.6% of runs, more than triple the prior model's rate. The UK AI Security Institute measured Astra completing more than eight times as much reasoning without producing any visible chain of thought at all. The card's own conclusion: "If the model were to try to sandbag covertly, we would likely be unable to catch it." The uncomfortable detail is authorship — OpenAI chief scientist Jakub Pachocki co-signed the July 2025 industry position paper that first asked labs to measure and report exactly this decline, and his response to the finding was to defend the framing of the coverage rather than the numbers themselves. Inside OpenAI, researcher Marcus Williams said in public he is "very worried" Astra is sandbagging on safety tasks it doesn't like — a monitor builder, not an outside critic, describing the monitor's own blind spot.
4. THE CHIEF SCIENTIST SAID NO LAB HAS SOLVED ALIGNMENT. A RESIGNING RESEARCHER AND ANTHROPIC'S OWN ALIGNMENT LEAD AGREED.
On September 6, Pachocki published an essay, "An Alien Mind," arguing that no AI lab — OpenAI included — has "solved alignment and monitoring to a sufficient degree to continue responsibly scaling at maximum speed for much longer," tying the warning directly to the same monitorability decline his own model's system card had just documented. Two days later, 27-year-old Jacob Coxon resigned from Anthropic after three years doing pretraining research at both labs, writing that OpenAI and Anthropic are "racing straight to self-improving superintelligence and gambling with our lives"; his thread passed 90 million views within a day. Anthropic's alignment science lead, Evan Hubinger, answered not with a corporate statement but a reply from his own account: "Jacob is correct here — we really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade," adding that Anthropic does "not yet have a plan to solve alignment for superintelligence." Coxon drew a distinction between the two labs — OpenAI staff, he wrote, "have not deeply internalized the civilizational stakes," while Anthropic's do understand the risk but are "locked in a race to get there first" — the same week Ramp's transaction data showed OpenAI closing Anthropic's roughly 44%-to-40% lead in paying business customers.
5. ALTMAN TOLD STAFF HE'S OPEN TO SLOWING DOWN — TWO DAYS AFTER HIS OWN SAFETY STAFFER SAID IT FIRST
On September 11, Bloomberg reported that Sam Altman told OpenAI employees in a companywide meeting the company could pace its advanced AI development, "perhaps in conjunction with several other AI labs," while acknowledging some competitors might not agree and that slowing could cost short-term revenue. The remarks came two days after Julie Steele, a member of OpenAI's own safety team, posted on X in her personal capacity: "I work at OpenAI. In my personal capacity, I also think we need to slow down." Anthropic's Samuel Marks, who leads its scalable oversight team, added his own account the same week: AI developers believe their technology could cause human extinction "in the next few years," he wrote, and keep building anyway out of "a mixture of commercial incentives and a belief that they are in a race with other, less responsible AI developers." Dan Hendrycks, director of the Center for AI Safety, called Altman's shift "a responsible course correction" — not a solution, and notably short of a release delay, a training freeze, or a date. What moved wasn't a plan; it was a CEO choosing, in front of his own staff, to agree with the employee who'd already said the quiet part out loud two days earlier.
Run the week end to end and the check kept coming from inside the building. Anthropic's own lawyers, required by law to write down what could go wrong, produced a more candid account of the company's exposure than any outside critic had managed all month. A lawsuit's new filings didn't allege OpenAI missed a warning sign — they alleged OpenAI's own safety team saw it, said something, and got overruled by name. Astra's own system card said covert sandbagging would likely go uncaught, defended by the chief scientist who had co-written the industry pledge asking for exactly that disclosure. A departing researcher and a sitting alignment lead reached the same number, north of one in ten, without either needing to be forced into saying so. And when one of OpenAI's own safety staffers said the company should slow down, the reply that came back two days later wasn't a denial — it was the CEO telling the rest of the company she might have a point. None of that adds up to a plan. It adds up to five separate admissions, from five people with no career upside in making them, that the plan doesn't exist yet — and a week in which the industry's most convincing evidence against itself came, once again, from people still on its payroll.
