The same S-1/A added a new paragraph in the risk factors section: Anthropic is increasingly using AI to accelerate its own research and development, which may cause model capabilities to advance faster than safety, alignment, and security measures can keep up; the company has previously failed to promptly detect significant acceleration in R&D and may do so again in the future, discovering it only after the fact. The prospectus states that, based on internal estimates and expectations for future models (rather than existing models), the company "may be about to" reach the definition of "significant accelerated progress attributable to AI" in its Responsible Scaling Policy (RSP); currently, no existing model has been determined to have crossed this threshold, and relevant data is still being evaluated. The company also stated that it is considering revising the RSP to require human review and approval for certain decisions in the R&D process.

Reasoning
- "AI helping to build stronger AI" (often referred to by the media as recursive self-improvement, or RSI) has long been considered one of the highest-risk capability thresholds; this time, a frontier lab acknowledged in a legally binding securities filing, rather than in a blog post or interview, that it may be approaching this point.
- The prospectus also explicitly states: the company expects that even when technically feasible, it will not be able to safely allow Claude to fully autonomously design and train the next generation of frontier models without meaningful human oversight and understanding; it also mentioned delaying the pre-training of a new frontier base model by more than a month to strengthen security measures preventing weight leakage.
- For those focused on AI regulation, this provides a specific, trackable commitment: Anthropic states it will publish follow-up reports in accordance with the RSP.
Usage
- The original text can be found in the "Risk Factors" section of Anthropic's S-1/A on EDGAR (search for "dramatically accelerated progress attributable to AI"); for follow-up reports, monitor Anthropic's RSP page.
Risks
- The prospectus is a risk disclosure, using the wording "may," not announcing that it has already been achieved; TechCrunch also notes that prospectuses serve a marketing function as well.
- The prospectus does not specify how soon "about to" refers to or how the threshold is measured; one must wait for the reports Anthropic publishes in accordance with the RSP.
