AI developers Anthropic and OpenAI · Outcomes due 18 December 2026

At least one of Anthropic or OpenAI publicly establishes a named arrangement for embedded external evaluation with concrete access and disclosure terms.

Embedded external evaluation means an outside organisation testing a company’s AI systems with continuing access inside the company.

Resolution test: An agreement, published terms or confirmation that access is operating counts. Repeating the September promise does not.

   Anthropic has named Accenture, but its September 18 announcement still leaves operating and disclosure standards unsettled. That announcement belongs to the baseline. A new arrangement or confirmation of operating access needs to satisfy the concrete test; another promise alone is insufficient.

3. 20 September 2026 · Open

   Anthropic named Accenture on September 18, before the period counted by this forecast. That announcement cannot fulfil the prediction. The evaluator letter published that day seeks access, editorial control and protection against retaliation, underscoring that naming an inspector and giving it enforceable freedoms are separate steps. A new qualifying arrangement or confirmation of operating access is still required; the estimate is unchanged.

   METR’s September 22 report describes operating access at Anthropic and a contract allowing disclosure of access and redaction facts without company consent. A separate team assessed AI research inside the company with elevated access. This moves beyond a promise to admit outsiders and raises our estimate that a named embedded arrangement with specified terms will be established. The report does not settle the continuing scope or terms of that separate team’s work, so the prediction remains open. “Embedded” was not precisely defined in the original test; this review does not add a requirement of permanent physical residence.

   Anthropic and OpenAI both signed the September 29 White House accord, which commits each company to partner with an independent external auditor or evaluator. The accord names no auditor and sets no access or disclosure terms, so signing it does not meet this test, which requires a named arrangement with concrete terms. Two announcements now follow the same pattern: Anthropic’s September 18 Accenture partnership and the accord both name an intention to be audited while leaving access and publication unsettled. Pressure to name an evaluator has grown, but so has the evidence that the companies can satisfy it without stating terms, and 79 days remain. We lower our estimate from 85% to 73%.

   On October 9, answering an open letter from three safety staff it had dismissed, OpenAI said it is “actively finalizing contracts with third-party safety assessors” and expects to give details in the coming weeks. The statement names no assessor and sets out no access or disclosure terms, so it renews a promise rather than meeting the test, which needs an agreement, published terms or confirmation that access is operating; Anthropic’s planned testing deal with Australia’s AI Safety Institute also has no published terms. The dismissed staff, one of whom says he was METR’s technical contact in the investigation of the Hugging Face attack, warn that the firings could be used to end OpenAI’s work with METR, so the promised contracts may name assessors other than the evaluator OpenAI has worked with. A fresh set of three estimates on this evidence gave a median of 70%, within the spread of the samples around our current 73%, so the estimate is unchanged.

    Reuters reported on October 13, citing two people familiar with the talks, that as recently as October 5 Anthropic and OpenAI were seeking strict control over what embedded evaluators could publish; one person familiar with the matter said Anthropic’s talks with some evaluators appeared to have moved on by October 8, and a contract Reuters saw shows that labs’ existing contracts can bar evaluators from publishing confidential information without the companies’ consent. Anthropic answered that evaluators it has worked with before control their methods, conclusions and what to publish, but that it reserves the right to approve reports by new firms; OpenAI said it seeks no approval over the full text of reports, redacts confidential material and lets evaluators disclose whether it made major redactions. These are descriptions of negotiations, not a named arrangement with published access and disclosure terms, so the prediction is not met. With the disclosure terms still unsettled and about nine weeks left, a fresh set of three estimates lowers our estimate from 73% to 62%.

    On October 15 Anthropic published the terms of an arrangement with the evaluator METR: six METR employees now work inside the company with its hardware, office space and access to internal tools and systems that it describes as roughly on par with its own risk-assessment teams’, excluding customer data, legally privileged material and details of how its models are built. METR will publish its own analysis of Anthropic’s risks, incidents and practices without Anthropic’s approval; Anthropic may require redactions only in categories fixed in advance, and METR may say publicly whether it thinks a redaction was justified. That is a named arrangement for embedded external evaluation with concrete access and disclosure terms, and Anthropic’s statement that the team has been onboarded confirms that access is operating, so the prediction is met. The arrangement was announced after September 18; METR’s eight-week mandate to investigate Anthropic’s incidents, given on September 9, and its September 22 report are not what resolves it. The terms are Anthropic’s own account, and whether the right to publish binds will show only in what METR publishes.

AI developers Anthropic and OpenAI · Outcomes due 18 December 2026

Both companies launch or substantially expand paid model or agent products before binding industry-wide pacing restrictions take effect.

Model products provide access to a trained AI system; agents use such systems to take actions on the user’s behalf. Pacing restrictions limit how quickly companies develop or release the most capable AI systems. An API lets other software use a company’s AI system.

Resolution test: A public new release or substantial expansion at each company, after September 18 and before any binding industry-wide pacing regime. This is compatible with their stated proposals and is not itself evidence of hypocrisy.

2. 93%19 September 2026 · Open

   Anthropic explicitly plans to continue training and releasing models alongside outside evaluation, and OpenAI is expanding its paid offerings. The estimate rises because each company has several routes to a qualifying expansion before a binding industry-wide pacing regime takes effect.

Chipmaker Nvidia and Facebook’s parent company, Meta · Outcomes due 18 December 2026

Nvidia announces a new funded initiative, product or government partnership for AI security, monitoring or defensive use without endorsing a general frontier slowdown.

   On September 28 Nvidia launched its Open Agent Safety Platform, pairing its OpenShell agent runtime, now broadly available, with Nvidia Sentry, a newly announced design for a monitor running on BlueField-4 networking chips that watches AI agents and can quarantine one that leaves its permitted boundaries. Nvidia gives no general-availability date for Sentry. More than 100 organisations are named as partners, including Anthropic, Microsoft and SpaceXAI. OpenShell was announced in March and cannot count again, but the combined platform, with Sentry and its named partner integrations, is a new identifiable product for AI security and monitoring, which meets the test. Neither the announcement nor Nvidia’s technical account endorses a general frontier slowdown; the technical account instead calls for faster safety research alongside continued development. Nvidia names no funding amount or government partner, which the test does not require. The outcome supports our reading of Nvidia’s commercial position without establishing Huang’s motives.

   Clarification of the same-day entry. Nvidia Sentry is a design without a release date, a monitor that would run on BlueField-4 networking chips; OpenShell, the agent runtime, is available now. OpenShell was announced in March, and Nvidia had already described security partnerships built around it, so neither can count again; the newly launched platform, with the new Sentry design and more than 100 named partners, is a new identifiable product for AI security and monitoring, which meets the test. Neither the announcement nor Nvidia’s technical account endorses a general frontier slowdown; the announcement instead quotes Huang calling for faster safety research. The earlier entry’s claim that the technical account calls for faster safety research alongside continued development, and its treatment of the partner integrations as new, are withdrawn. The outcome supports our reading of Nvidia’s commercial position without establishing Huang’s motives.

Chipmaker Nvidia and Facebook’s parent company, Meta · Outcomes due 18 December 2026

Meta expands public access to an agent or advanced model and issues a new public objection to general pacing requirements.

An agent uses AI to carry out tasks for its user; pacing requirements limit the speed of AI development or releases.

Resolution test: Both a new substantive availability/capability expansion and a new attributable policy statement or lobbying position must occur. Existing Muse availability and the August essay are the baseline.

   Meta has announced further Muse expansion, but delivering it and issuing a new objection to general pacing are separate requirements.

We preserve that ambiguity and the previous 72% estimate rather than count a later publication as an unambiguous new action.

The second half needs a new attributable objection to general pacing requirements. The same day Zuckerberg told the Financial Times, in the words an excerpt quotes, that AI “can be engineered with normal guardrails,” and the paper says he put responsibility for safety on each lab; on a podcast he called models held in “a couple companies’ hands” “a riskier configuration.” The excerpt’s headline says he rejected calls for a slowdown, though the FT text it quotes says he had done so previously, and none of his words we could read objects to a pacing requirement, so the prediction stays open. With the expansion settled and Zuckerberg addressing the question publicly, a fresh set of three estimates raises our estimate from 72% to 83%.

It requires prompt public incident reporting, auditor control of investigation scope and independent publication of findings. These specific duties meet the original formal-policy-proposal test; acceptance by a lab or government was not required. The statement is first verified here on September 26. It refers to the countries’ human-control call this week and last year’s Red Lines launch, placing it within the September 21–25 assembly week, after the forecast began; the page supplies no exact publication timestamp.

Independent AI safety inspectors, including METR · Outcomes due 18 December 2026

A named independent evaluator publishes new empirical results that narrow a prominent claim about dangerous capability, autonomous research or productivity.

Fable 5.1 is an earlier Anthropic AI system. Long-horizon tasks require many connected steps.

Resolution test: The report must identify a measured limitation or place a named system below a stated risk threshold. Merely saying evidence is uncertain, or republishing an older reassuring result, does not count.

At least one materially qualified or corrected technical claim is subsequently repeated in a stronger form by two identifiable pause-campaign leaders or organisations.

The administration does not endorse legally binding general limits on the pace of frontier training or model releases by the deadline.

Frontier training is the process used to build the most capable AI systems; model releases make trained systems available to users.

   The United States and China have now agreed a dialogue on advanced AI, due to meet by November, and a channel for reporting incidents; neither government’s text limits training or releases. On September 26 President Trump said the United States “is not going to be putting on brakes” and would rather not integrate its AI work with China’s. Both developments are consistent with this forecast; as an absence forecast it cannot resolve before the deadline, and the fresh estimates gave no reason to change the published probability.

   The administration’s first formal instrument on the safety of the most capable AI, the September 29 accord, is voluntary and says nothing about the pace of training or releases. Trump called it “morally binding” and praised self-regulation, and Vice President Vance, as reported, told the executives to take the risks seriously rather than ask the government for a regulatory regime. The accord’s remark that it may make sense to codify its steps refers to controls and audits, not to pace. The same day a Quinnipiac poll found 79% of voters putting safety ahead of staying at the forefront, pressure that could matter after a serious incident; but the administration answered that pressure with a pledge the companies wrote for themselves. With 79 days left, we raise our estimate that the administration will not endorse binding general pace limits from 80% to 96%.

The administration announces a new concrete AI-security, infrastructure or government-access initiative with industry partners.

Resolution test: A signed agreement, order, procurement decision or funded programme counts. A promise of American dominance or an unresourced speech does not.

2. 96%19 September 2026 · Open

   Government-industry AI security and access work already has an executive framework. The forecast allows a new agreement, procurement decision, order or funded programme, so several kinds of concrete follow-through qualify. Repeating an earlier directive or announcing an unfunded intention does not.

   The administration’s voluntary AI-security framework

3. 20 September 2026 · Open

   Trump’s September 19 promise of an AI Force falls inside the forecast period, but the statement names no industry partner and supplies no budget, signed agreement, order or procurement decision. It strengthens the evidence of intent without establishing the concrete action required here. The forecast remains open at the same estimate.

4. 30 September 2026 · Forecast met

   On September 29 President Trump and the heads of Google, Anthropic, Meta, xAI and Nvidia, with OpenAI’s president, Greg Brockman, signed the White House Accord on Super Intelligence, which Trump then posted. Each company commits to four layers of AI-security controls: internal monitoring of its models for cyber, biological and chemical threats and against unintended hacking, an internal team to check those controls, an independent external auditor or evaluator, and a board committee that receives the reports. The test counts a signed agreement on AI security with industry partners, and this is one, so the prediction is met. The accord is voluntary: it names no auditor, sets no deadline or duty to publish, and leaves enforcement to no one. It meets the letter of this test without giving the government new powers over the companies.

Senators Bernie Sanders and Elizabeth Warren · Outcomes due 18 December 2026

Sanders or Warren advances a new legislative amendment, package or formal platform connecting AI governance to worker compensation, working hours, bargaining power or ownership.

Representative Greg Casar joined Senator Bernie Sanders in introducing the September 23 bill.

Resolution test: The action must add a provision, legislative vehicle or joint commitment beyond the existing September proposals. Repeating the current workweek bill in an interview does not count.

1. 65%18 September 2026 · Original forecast

2. 77%19 September 2026 · Open

   Sanders's workweek proposal and the announced Sanders–Casar bill establish an active policy agenda. The estimate concerns an additional worker-related provision, vehicle or formal commitment from Sanders or Warren. Repeating either existing proposal would leave the forecast open.

3. 58%24 September 2026 · Open

   The full Sanders–Casar bill introduced September 23 creates a proposed AI regulator and protects whistleblowers, but contains no working-hours, compensation, collective-bargaining or worker-ownership provision. The earlier shorter-workweek proposal already addressed workers’ gains and cannot count again. The new text shows the development restrictions and specified worker benefits proceeding on separate legislative tracks, reducing this estimate from 77% to 58%. A later amendment, new vehicle or formal joint commitment could still satisfy the original test before December 18.

Senators Bernie Sanders and Elizabeth Warren · Outcomes due 18 December 2026

A national labour or consumer organisation newly endorses an advanced-AI pause or permission requirement promoted by this political camp.

Resolution test: A formal new organisational endorsement of the development restriction counts. General support for worker protection or safer chatbots is insufficient.

1. 60%18 September 2026 · Original forecast

2. 42%19 September 2026 · Open

   Labour endorsements of the shorter-workweek bill concern how productivity gains are shared. They do not commit those organisations to restricting model development. The revised estimate separates sympathy for worker protection from a new formal endorsement of a pause or permission requirement.

3. 27%27 September 2026 · Open

   The Sanders–Casar bill introduced on September 23 is the camp’s concrete pause and permission measure, and its announcement lists no national labour or consumer organisation. The labour endorsements in the record belong to the shorter-workweek bill, and a search summary attributing union endorsements to the ban was checked and rejected. The organisations that attended the September 15 assembly give a route to endorsement, but the test requires a formal endorsement of the development restriction itself.

   Clarification of the same-day entry, which omitted the earlier estimate. The Sanders–Casar bill introduced on September 23 is the camp’s concrete pause and permission measure, and its announcement lists no national labour or consumer organisation. The labour endorsements in the record belong to the shorter-workweek bill; an online search summary that attributed union endorsements to the ban was citing another bill’s list of endorsers. The labour organisations that attended the September 15 assembly offer a route to endorsement, but the test requires a formal endorsement of the development restriction itself, and none has appeared, so we lower our estimate from 42% to 27%.

Pennsylvania’s government and the U.S. Congress · Outcomes due 18 December 2026

A congressional committee holds an AI oversight hearing or advances legislation specifically addressing incident reporting, independent evaluation or development security.

Resolution test: A held hearing, markup or recorded committee advancement counts. Another letter asking for action does not.

1. 75%18 September 2026 · Original forecast

2. 91%19 September 2026 · Open

   A bipartisan group has identified existing oversight legislation and pressed for action. One qualifying hearing or committee advancement is enough; enactment is not required. The estimate includes both chambers, although no specific forthcoming qualifying hearing was verified in this review.

   A Senate homeland-security subcommittee chaired by Josh Hawley has scheduled a September 30 hearing on rogue AI agents, according to a legislative news service. A scheduled hearing does not satisfy the test. If it is held and addresses how developers secure their systems or report incidents, it would; we will judge its actual scope. The House Energy and Commerce chair has signalled that major AI legislation is unlikely to advance before 2027, which bears on the legislative route but not on hearings.

4. 1 October 2026 · Forecast met

   On September 30 the Senate Homeland Security and Governmental Affairs Committee’s Subcommittee on Disaster Management, District of Columbia, and Census, chaired by Josh Hawley, held a hearing titled “Rogue AI: Securing the Homeland Against AI Agent Attacks.” Its witnesses, from the evaluators METR and Apollo Research, Georgetown Law, the security firm Dragos and the AI Futures Project, addressed how AI agents escape restrictions, the independent investigation of OpenAI agents’ July attack on Hugging Face, public reporting of agent incidents and required embedded evaluation. The test counts a held hearing addressing incident reporting, independent evaluation or development security, and this one addressed all three, so the prediction is met. It was held by a subcommittee, which we count as the committee acting; it heard proposals, including Hawley’s planned liability bill, but advanced no legislation.

The test counts a held hearing addressing incident reporting, independent evaluation or development security, and this one addressed all three, so the prediction is met.

Pennsylvania’s government and the U.S. Congress · Outcomes due 18 December 2026

Pennsylvania adds a binding AI procurement, operational-safety or data-centre condition while continuing to back a named new AI investment or deployment.

Resolution test: Both a new enforceable condition and a new identifiable state-backed investment/deployment must appear. A speech alone is insufficient; the previous August data-centre order is the baseline.

2. 29%19 September 2026 · Open

   Pennsylvania's August data-centre order is already in the baseline. Another enforceable condition and a newly identified investment or deployment must both appear. Estimating those requirements separately lowers the combined probability. The U.S. House recess supplies no evidence about Pennsylvania's legislature.

Chinese AI developers DeepSeek, Moonshot and Z.ai · Outcomes due 18 December 2026

At least one of DeepSeek, Moonshot or Z.ai releases new downloadable model weights or general agent tooling explicitly promoted as improving cost, access or performance.

Downloadable model weights let others run and adapt a trained AI system. Agent tooling uses such systems to carry out tasks for a user.

Resolution test: A usable new release after September 18 counts. A benchmark tease, an old release gaining attention or an announcement with no accessible artifact does not.

1. 85%18 September 2026 · Original forecast

2. 98%19 September 2026 · Open

   Moonshot and DeepSeek have recently released usable weights and supporting tools. This forecast needs one qualifying new release from any of three developers, rather than a particular next-generation breakthrough. The high estimate is a judgement about continued activity, not a fitted release-frequency model.

   Moonshot’s July release, DeepSeek’s official model repository

   Three estimates from one AI model, Claude Opus 5: 98%, 98%, 97%.

3. 21 September 2026 · Forecast met

   Z.ai published ZCode’s agent runtime and desktop, web and command-line source under Apache-2.0 on September 20. The official announcement promotes wider source access and community scrutiny. This is newly downloadable agent tooling for an existing product, not new model weights: the repository includes runtime files and build instructions, rather than only a future promise. It meets the forecast’s tooling-and-access branch. The release followed a privacy complaint; the outcome does not establish the commercial motive proposed in the essay.

Chinese AI developers DeepSeek, Moonshot and Z.ai · Outcomes due 18 December 2026

None of these three developers publicly joins a binding, independently verifiable international agreement limiting frontier training or release cadence by the deadline.

These limits would govern how quickly the companies develop or release their most capable AI systems.

Resolution test: A general statement supporting safety or international cooperation is not such an agreement. Public accession to concrete reciprocal limits with a verification mechanism resolves this forecast negatively.

1. 80%18 September 2026 · Original forecast

2. 97.5%19 September 2026 · Open

   The agreement must impose concrete reciprocal limits with independent verification, and a named developer must publicly join it. General safety declarations or exploratory talks do not meet that test. The higher estimate reflects the demanding agreement required within three months, not proof that no private negotiations exist.

   Amodei’s pacing proposal, Moonshot’s July release

   Three estimates from one AI model, Claude Opus 5: 97.5%, 98%, 97%.

   The new U.S.-China dialogue and incident channel are arrangements between governments; they name no company and impose no verifiable limit on training or release cadence. DeepSeek, Moonshot and Z.ai have not joined any such agreement. The forecast remains open until the deadline.
