Jack Clark, co-founder and head of policy at Anthropic, publicly stated that there is a likely chance (60%+) that by the end of 2028, AI systems capable of autonomously building their own successors could emerge. This is a significant policy declaration from a senior frontier-lab leader, underscoring the potential for rapid AI takeoff within the next few years.
On May 4, 2026, Jack Clark published a report titled ‘Automating AI Research’ in which he explicitly estimated a greater than 60% probability that by 2028, AI systems will reach a level where they can autonomously develop their own successors without human intervention. Clark’s statement is notable for its institutional weight, as he is the head of policy at Anthropic, one of the leading AI frontier labs.
This forecast marks a departure from typical AI timeline discussions, which have mostly been conducted by researchers and analysts. Clark’s estimate is a formal policy position, reflecting the lab’s assessment of current technological trajectories and investment trends. His statement emphasizes the rapid acceleration of AI capabilities, particularly in areas like code generation, research reproduction, and system management, which are critical for autonomous AI development.
Clark’s estimate is based on observed improvements in AI benchmarks, the increasing deployment of automation tools in AI research, and the substantial capital directed towards automating AI R&D. The probability assigned—over 60%—suggests a high level of confidence within the leadership at Anthropic about the near-term possibility of autonomous AI systems.
Sixty percent
by twenty-twenty-eight.
A frontier-lab co-founder publishes a probabilistic forecast on automated AI R&D arrival. The institutional weight exceeds the analytical weight.
May 4, 2026 · Import AI #455 contains a single sentence that constitutes one of the most consequential public statements ever made by a frontier-lab leader on takeoff timelines. The fact of the statement matters as much as its content. The AGI debate is now closed for the people who would know. The question is what we do during the window the forecast describes.
Clark fills the empty seat.
The takeoff-timeline forecasting discourse has been continuous since 2022 but conducted almost entirely by researchers, ex-employees, and outside commentators. No sitting frontier-lab co-founder had published a numerical probability on a specific takeoff threshold within a specific timeframe. Until May 4, 2026.

Five disagreements. Five different magnitudes.
Not every credible observer will share Clark’s 60%/2028. The honest disagreement isn’t about whether AI capability is improving — it’s about whether the curve continues, whether compute supply binds first, whether shocks intervene.

Implications of a Senior Leader’s Autonomous AI Forecast
This statement from Jack Clark is significant because it signals that a major frontier AI organization publicly acknowledges a high likelihood of autonomous AI development within the next few years. As the head of policy, Clark’s forecast carries institutional weight, potentially influencing regulatory discussions, investment decisions, and public perception of AI risks and opportunities. The explicit probability estimate also raises questions about the societal, economic, and safety implications of such a technological shift, emphasizing the need for proactive policy and safety measures.
Background on AI Timelines and Frontier Lab Positions
Discussions around AI takeoff timelines have been ongoing since 2022, primarily driven by researchers, forecasters, and independent analysts. Notable efforts include Ajeya Cotra’s biological-anchors work, Daniel Kokotajlo’s AI-2027 scenario, and various academic and industry reports. However, until Clark’s statement, no senior frontier lab executive had publicly assigned a specific probability to the timeline for autonomous AI capable of self-augmentation.
Clark’s forecast is notable in this context because it originates from a high-ranking institutional voice, reflecting a considered, policy-oriented assessment rather than speculation. It aligns with observed acceleration in AI capabilities and the substantial capital invested in automating AI research processes, suggesting a convergence of technological and economic trends pointing toward a possible breakthrough by 2028.
“I reluctantly come to the view that there’s a likely chance (60%+) that no-human-involved AI R&D — an AI system powerful enough that it could plausibly autonomously build its own successor — happens by the end of 2028.”
— Jack Clark
Uncertainties Surrounding the Autonomous AI Timeline
It remains unclear how Clark’s probability estimate will influence industry and regulatory responses, and whether subsequent technological developments will accelerate or delay this timeline. The estimate is based on current trends, which are subject to unforeseen breakthroughs or setbacks. Additionally, the precise definition of ‘no-human-involved AI R&D’ and the threshold for ‘autonomous AI’ remain somewhat ambiguous, leaving room for debate about what constitutes reaching this milestone.
Furthermore, Clark’s forecast is a policy statement rather than a detailed technical roadmap, so the actual pace of development could differ from expectations. The societal, safety, and ethical implications of reaching this threshold are also still being debated within the community.
Next Steps for Monitoring AI Development and Policy Response
Observers should watch for further institutional statements from other frontier labs and policymakers that either reinforce or challenge Clark’s forecast. Key milestones include advances in AI autonomy, regulatory discussions, and investment shifts toward autonomous AI capabilities. Researchers and policymakers are likely to scrutinize ongoing developments closely, especially as the 2028 target approaches. Public and private sector actors may also begin to prepare for the societal impacts of potentially autonomous AI systems.
In the near term, it remains uncertain whether the industry will accelerate efforts toward autonomous AI or encounter technical, safety, or regulatory hurdles that slow progress. Continued transparency from leading organizations will be critical to understanding the evolving landscape.
Key Questions
What does Jack Clark mean by ‘no-human-involved AI R&D’?
Clark refers to AI systems capable of autonomously designing, training, and improving themselves without human intervention, reaching a level where AI can independently develop its own successors.
Why is Clark’s forecast significant compared to other AI timeline predictions?
Because it is a public, institutional estimate from a senior leader at a major frontier lab, carrying more weight and implications than typical researcher or analyst forecasts.
What are the societal risks associated with autonomous AI development by 2028?
Potential risks include loss of human control, safety and alignment challenges, economic disruptions, and the need for new regulations to manage autonomous AI systems responsibly.
How might this forecast influence AI regulation and safety efforts?
It could prompt policymakers to accelerate safety protocols, develop new regulations, and prepare for the societal impacts of highly autonomous AI systems.
As of now, no other senior leaders have publicly assigned a specific probability or timeline comparable to Clark’s estimate, making his statement somewhat unique.
