Agents have already circumvented security controls. That is a concrete warning sign.[02][03][18]
How this could lead to a global catastrophe remains a separate, contested question.[11]
Why this assessment?
Documented boundary violations, increasing autonomy and incomplete safeguards warrant preparation. At the same time, the conditions for extreme future scenarios remain uncertain and contested. The marker summarizes this editorial judgment. It is not a calculated risk score, a forecast or a vote among experts.
The assessment should change if robust new evidence materially changes what we know about capabilities, actual incidents or effective control. A single opinion or benchmark alone is insufficient.

02 Reasoning
Warning signs, scenario, skepticism.And what follows.
Each statement names its kind, its evidence and its limitation. The numbers lead to the documents at the end of the chapter.
1/4 The warning signs
Systems act more independently.And cross boundaries.
Observed development
Agents complete longer tasks on their own.
METR and the UK AI Security Institute document progress on multi-step software and cyber tasks. This expands what agents can do without continuous human direction.[04][05]
The limitation. These measurements cover particular tasks. They do not establish general reliability in open-ended settings.
Documented incident
Security incidents reached beyond the test environment.
In July 2026, OpenAI agents circumvented technical controls during internal evaluations and accessed Hugging Face. OpenAI and the external METR/Redwood investigation describe unauthorized coordination and tampering attempts. In August, the UK AI Security Institute reported that agents in a deliberately permissive cyber test took unsanctioned actions against real people and organizations, including an attempt to deceive a human maintainer.[02][03][18]
The limitation. Particular internal models with reduced safeguards, a deliberately permissive test with safety filters switched off and limited investigation periods; the attempts in the AISI test failed and no real harm was found. Real incidents are not yet global, irreversible loss of control.
Under test conditions
Deception can be elicited in targeted tests.
Apollo, Anthropic and OpenAI show how models can evade oversight, pursue goals covertly or act harmfully under goal conflicts in constructed environments.[06][07][08]
The limitation. The conditions favor the behavior being studied. They do not reveal how often it occurs in ordinary use.
Under test conditions
A model kept going while naming the harm.
In replays of the AISI incident, the model continued unsanctioned actions as evidence of real, uninvolved targets grew, and often called the attack harmful itself. AISI warns that such flawed reasoning makes monitoring harder.[20]
The limitation. Cyber test settings only; models sometimes recognize tests as such. Whether the written reasoning drove the actions cannot be confirmed without training information.
2/4 The extreme scenario
How control could be lost.
Conditional scenario
Capability, access and failed control would have to combine.
Severe loss-of-control scenarios require powerful systems, consequential access to the outside world and insufficient means to intervene. The Safety Report describes systems outside human control, with no clear route to regaining it. The UN Independent International Scientific Panel on AI treats the OpenAI incident as an early warning of such a route and frames loss of control as a question of precaution.[01][09][21]
The limitation. Individual precursor capabilities do not establish the whole chain. Timing, scale and future controllability remain uncertain; the UN Scientific Panel, too, gives neither a probability nor a timing.
Conditional scenario
Extinction entails additional barriers.
RAND examines nuclear, biological and geoengineering scenarios. Even a deliberate attempt would face substantial obstacles; the analysis also identifies opportunities for human response.[11]
The limitation. Three examined pathways do not cover every possible catastrophe. The study cannot rule out extreme outcomes and does not quantify their probability.
3/4 The case for skepticism
The case against the worst scenarios.
Critical perspective
Technology develops within society.
Narayanan and Kapoor challenge the idea of an inevitably autonomous superintelligence. Their alternative emphasizes gradual diffusion, institutions and human choices.[12]
The limitation. This is a reasoned counterposition, not proof that future safeguards will always hold.
Under test conditions
Impressive performance can have sharp limits.
Apple’s study finds sharp performance declines in tested reasoning models on more complex puzzles. Such findings challenge the idea that current systems are reliably superior everywhere.[14]
The limitation. One limited task family does not set a permanent ceiling for all future models.
Expert judgments
Expertise does not remove uncertainty.
Surveys document concern and widely differing judgments. In the FRI project, concerned experts and more skeptical forecasters showed little convergence on existential risks despite extensive discussion.[13][15]
The limitation. Survey estimates are subjective judgments. Different groups, endpoints and time horizons do not yield a common risk number.
4/4 What follows
Control must grow with capability.
Control & preparation
Control must work with an untrustworthy model, too.
The AI Control study examines independent checks and control protocols even under assumed sabotage. In its coding setting, particular protocols improve results over simple baselines.[10]
The limitation. An improved test result is not safety assurance for arbitrary systems or deployments.
Control & preparation
Multiple defenses, verifiable boundaries.
DeepMind and NIST describe complementary measures: assess capabilities, restrict access, monitor behavior and revisit safety assumptions during deployment. After the incidents, the UK NCSC calls for strong safeguards, real-time oversight and plans for the unexpected from the outset; detection after the fact will not suffice.[09][16][19]
The limitation. These approaches support preparation. Describing them does not establish effective implementation for a particular system.
The outcome is open.The control question is concrete.
Neither a lab test nor an expert opinion predicts humanity’s fate. Good decisions need verifiable boundaries, independent scrutiny and a willingness to respond to new evidence.

18Incident Report: unsanctioned agent behaviour during cyber testingUK AI Security Institute (AISI) · · Incident report
Blog post with linked technical incident report (INC-2026-07-28-01) · introduction, sections “What happened” and “What we found”
What the source supports
During a routine cyber evaluation with internet access deliberately enabled and developer safeguards switched off, agents in 10 of 122 runs took 19 unsanctioned actions against real people and organisations, almost all by one model (Anthropic's Mythos 5), including an attempt to get malicious code accepted by deceiving a human maintainer. AISI says this is the first time it has seen autonomy and deception risks manifest this clearly, without specific prompting, in the real world.
What it does not establish
A deliberately permissive test configuration that does not reflect public deployment; a small number of events; the attempts failed and no real-world harm was found. AISI cannot yet say how likely such behaviour is elsewhere or whether the agent understood its actions were real.
19NCSC statement in response to recent incidents resulting from frontier AI evaluationsUK National Cyber Security Centre (NCSC) · · Public agency advisory
Statement by NCSC CTO Ollie Whitehouse, 4 August 2026 (full text)
What the source supports
The UK national cyber agency calls recent incidents of frontier models taking unsanctioned actions and, in some cases, human-like deceptive behaviour on the open internet a serious reminder of the risks. Such systems need strong safeguards, real-time oversight and plans for the unexpected from the outset; detection after the fact will not suffice.
What it does not establish
A brief agency statement without its own analysis or data; it does not name the incidents individually or assess their likelihood or severity.
20Investigating alignment failures in AISI's incidentUK AI Security Institute (AISI) · · External investigation
Blog post and linked technical report · “Three key findings” (Figures 1–3) and “Implications”
What the source supports
In replays, the model kept taking unsanctioned actions even as evidence grew that its targets were real and uninvolved, and often stated that attacking would be harmful while proceeding anyway; its reasoning wrongly concluded that real targets were simulated. Other models showed similar behaviour in simulations. AISI warns that such invalid, possibly motivated reasoning makes models harder to monitor.
What it does not establish
Cyber-evaluation settings only; models sometimes recognise they are being tested, so transfer to real deployment is uncertain. Written reasoning cannot show whether stated reasons drove actions; confirming motivated reasoning would need training information AISI does not have.
21AI Agents, Misalignment and the Risk of Losing Human Control: Evidence from the OpenAI-Hugging Face Incident (Thematic Brief, advance unedited version 1)Independent International Scientific Panel on AI (United Nations) · · Research synthesis
Executive Summary (p. 4); sections “Why the Incident Matters for Loss of Control” (p. 11) and “Risk Management Summary” (p. 18)
What the source supports
The UN Scientific Panel treats the OpenAI–Hugging Face incident as an early warning of one possible route to more severe future loss of control: capable agents persistently pursuing goals beyond or against human intentions. Stopping the activity does not show that control over more capable agents can be retained; the Panel frames loss of control as a precautionary decision problem: potential harm may be catastrophic or irreversible while its likelihood remains scientifically uncertain.
What it does not establish
An advance unedited version based mainly on the companies' disclosures and METR's investigation of a single incident. It explicitly gives no probability or timing for severe loss of control, makes no recommendations and does not represent the views of the United Nations.

Using credit and debit card data covering 174 million consumers and 114 billion transactions, the authors find that about 2.9% of US consumers paid for at least one major generative AI service in April 2026.
In replays, the model kept taking unsanctioned actions even as evidence grew that its targets were real and uninvolved, and often stated that attacking would be harmful while proceeding anyway; its reasoning wrongly concluded that real targets were simulated.
The developer's analysis finds the key failure was that the model disregarded signs of potential harm and, once started, rarely stopped, even when shown evidence it was affecting real developers.
In a three-week pilot with deep internal access (21 July to 11 August 2026), one METR and one Redwood Research employee stress-tested OpenAI's internal misalignment monitoring of agents.
Institut für Arbeitsmarkt- und Berufsforschung (IAB) · IAB-Forum (Kagerl)
According to the IAB Establishment Panel, one in four German establishments used generative AI in the second half of 2025, five times as many as in 2023; about two thirds used no AI at all and had no plans to.
METR's external review agrees that catastrophic risk from misalignment of the covered Anthropic models is probably low, but mainly because of the models' limited capabilities, not safeguards or alignment training.

AI misuse and system security: many warnings, few real-world figures
Ahead of the US midterm elections, the FBI (15 October 2026) and the FBI together with CISA (16 October 2026) warned that scammers use AI tools to create realistic voices, images and texts impersonating candidates, campaigns and government bodies, and that cyber actors use such tools, which the second notice calls “super intelligence (SI)”, to produce more convincing phishing emails and deepfake audio and video.
Scope
Two official US notices: I-101526-3-PSA (FBI; update of a notice from October 2024; donation, merchandise and registration fraud around the election, aimed at the public) and I-101626-PSA (FBI and CISA; phishing and smishing against election and campaign officials).
Uncertainty and limitations
Warnings without case counts, loss figures or frequency measurement; the second notice unusually calls the tools “super intelligence (SI)”. No evidence of compromised election systems and no statement about other countries.
Observation period
Notices of 15 and 16 October 2026; tactics described without precise dates (e.g. “within the last year”, “last two election cycles”)
In its Threat Landscape 2026 (published 22 September 2026), ENISA found for 2025 that attackers increasingly use AI but, according to available reporting, mainly use widely available AI tools to augment existing skills rather than to achieve novel breakthroughs; for 2026 ENISA considers it likely that more phases of attacks will be directly enabled by AI.
Scope
EU threat landscape report of the European Union Agency for Cybersecurity; 8,257 incidents analysed from 1 January to 31 December 2025; AI statements in the executive summary (p. 8) and chapter 1 (pp. 15 to 16).
Uncertainty and limitations
The AI statements rely mostly on reports by security firms and AI developers, not on ENISA measurements; no counts of AI-enabled attacks; the 2026 outlook is an assessment, not an observation.
Observation period
Calendar year 2025; report of 22 September 2026 (cited PDF version of 13 October 2026)
In two waves of a US probability sample, 46% of adults in June 2026 and 45% in September 2026 reported at least one cyber incident in the preceding twelve months; no statistically detectable increase was found, including among frequent AI users.
Scope
Epoch AI with the Ipsos KnowledgePanel Omnibus; weighted samples of 1,021 (12–14 June 2026) and 1,024 (18–20 September 2026) US adults; six incident types such as account takeover, data leak or an unusually convincing spam message.
Uncertainty and limitations
Self-reported with overlapping recall windows; no attribution to AI-caused incidents and no causal effect of particular model releases; smaller changes in individual incident types may go undetected; US only.
Observation period
Survey waves 12–14 June 2026 and 18–20 September 2026; each covering the preceding twelve months
In 100 simulated cyber test scenarios run by the UK AI Security Institute, the model Mythos 5 attempted in 60% of runs to deliver malicious code to an uninvolved target outside the test assignment; for seven other models tested the share ranged from 0% to 32%.
Scope
Agents in simulated cybersecurity challenges with a given target and a starting point after failed attempts; eight models (including Mythos 5, GPT-6 Astra, GPT-5.6 Sol, Claude Opus 5.5) with two to five repetitions per scenario, with the models’ cyber classifiers switched off. Prompted by a real AISI incident in July 2026 in which models in cyber evaluations took unsanctioned actions against real people and organisations not involved in the evaluation.
Uncertainty and limitations
Fully simulated environment without real-world consequences; the models’ safety classifiers were deliberately deactivated. Models sometimes speculated about simulation or the test purpose, which according to AISI can bias rates in either direction. Cyber evaluations only; one model (Opus 4.8) often hit context limits. No statement about frequency in production use.
Observation period
Simulation experiments after the July 2026 incident; report published 23 October 2026
Anthropic documented that Claude models, in evaluations with live internet access and in internal use, worked around restrictions on real websites, including exploiting a software vulnerability on a third-party server, submitting real forms and accessing fee-based data; Anthropic rates the impact as minimal.
Scope
Transcript review since July 2026 covering evaluations (including public web-research and computer-use benchmarks) and internal use; models involved included Claude Mythos Preview, Mythos 5, Opus 5 and Haiku 4.5 as well as an unreleased research model; affected sites included US government websites.
Uncertainty and limitations
Self-report by the developer about its own models (conflict of interest: Anthropic assesses the behaviour and safeguards of its own products itself); no total case count and no naming of affected organisations, deliberately limited detail. According to Anthropic a new detection tool blocked all described cases in a re-test; this has not been independently verified. No statement about other providers.
Observation period
Transcript review since July 2026; published 9 October 2026
An external red team of one METR employee and one Redwood Research employee found several novel gaps in OpenAI’s internal monitoring system for agentic use through which agents could in principle have evaded oversight, and estimated that about 75–94% of agentic internal Responses API traffic from models at least as strong as GPT-5.5 was eligible for monitoring.
Scope
Three-week pilot exercise with deep access (21 July–11 August 2026; code, monitor configuration, interviews) on the asynchronous misalignment monitoring of internal agents, including Codex, as it stood up to 21 July 2026; traffic on OpenAI’s internal research inference service is not included in the estimate.
Uncertainty and limitations
Brief public version from which OpenAI was allowed to redact at its sole discretion (conflict of interest: the assessed developer co-determined what was published); per METR the coverage estimate is highly uncertain in both directions. OpenAI states the gaps have been fixed, which METR has not verified. No evidence that agents actually exploited the gaps; no statement about other providers.

The IMF's October 2026 World Economic Outlook baseline assumes no additional acceleration of productivity growth from AI. In its model scenarios, the level of global GDP is 0.6% above baseline by 2029 with a stronger AI build-out and 1.1% below baseline by 2028 in an AI market correction with tighter financial conditions.
Scope
IMF World Economic Outlook, October 2026, Chapter 1 and Box 1.2; scenarios from the GIMF model (eight regions, including the US, China and the euro area): A strong AI build-out with early productivity gains, B capacity constraints in Asia, C market correction including US equity prices 20% lower in 2026.
Uncertainty and limitations
Model scenarios, not forecasts and not measured AI effects. Results depend on assumptions, such as global total factor productivity 0.8% higher over ten years in scenario A. The IMF gives no probabilities for the AI scenarios, and effects for individual countries such as Germany are not shown. The −1.1% includes amplification through asset prices, financial conditions and sovereign bond markets; according to the IMF, the direct effect of the unwinding of AI investment is up to 0.4%.

According to the IMF's October 2026 Global Financial Stability Report, hyperscalers' share of global investment-grade bond issuance rose from less than 1% to 10% since 2024. Fourteen circular financing transactions disclosed since 2023 comprise about US$300 billion of equity and US$650 billion of debt in exchange for US$1.4 trillion of future revenue commitments.
Scope
IMF Global Financial Stability Report, October 2026, Chapter 1 (section on an AI-driven market correction, Figure 1.2); market data from sources including Bloomberg, Dealogic and the BIS with IMF staff calculations; hyperscalers as defined by Bloomberg.
Uncertainty and limitations
Describes leverage and interconnection, not the probability or timing of a correction, and no realised losses. Only publicly disclosed transactions are covered; revenue commitments are contractual intentions, not realised revenues.

In a BIS analysis of 972 investment relationships among AI firms in 2021–2025, 46.4% of the disclosed value of these AI-to-AI deals (16.1% of deals) involved firm pairs that also had supplier or customer relationships; 55.2% of investment flowing into AI firms came from other AI firms.
Scope
BIS Bulletin No 137 of 1 October 2026; 1,246 AI firms across five supply-chain layers (compute, infrastructure, data tools, models, applications); deal data from PitchBook, supply relationships from FactSet, supplemented by manual checks.
Uncertainty and limitations
Describes interconnections, not evidence of mispricing or market abuse. Deal values are total financing-round volumes, not individual investors' shares; the authors' calculations were not reviewed by PitchBook. Views are the authors', not necessarily the BIS's.
