Anthropic's amended prospectus says it has met its safety threshold for AI-accelerated research

Yahoo Finance reports that Anthropic's amended IPO prospectus, filed on Tuesday, November 10, says the company has met a threshold in its Responsible Scaling Policy that it had earlier said it might "imminently" meet. According to the article, the filing says: "We made a determination that we have met this threshold," based on "what we expect from future models and our overall rate of progress, rather than on what we have observed from current models."

According to the article:

• The threshold is reached when AI does enough of Anthropic's research to roughly double the speed at which its models improve. The filing says AI "has already been accelerating our research and development." Crossing it means more safeguards, not a shutdown.
• Anthropic says it is still weighing what crossing the threshold means and will release further reports. It is considering policy changes "to keep humans in control," and does not expect to safely use Claude to design and build successive generations of frontier models fully autonomously without meaningful human supervision.
• The filing warns that as Anthropic uses Claude to speed up its work, its organization "may lose visibility across certain processes" in a way that may become hard for people to understand and control.
• The article notes that METR estimated last week that Anthropic's models have been improving nearly twice as fast since October 2025, and that a separate METR review called Anthropic's August argument that it was still below the threshold "overstated".
• The same filing sets a price range of $70 to $78 per share; trading could start as soon as November 19, according to reports.
