Anthropic, the AI laboratory behind the Claude models, has warned prospective investors in its initial public offering that its most advanced systems could present “catastrophic or existential risks to humanity.” The caution appears in a prospectus reviewed by Reuters and is notable for its explicit reference to potential human extinction, a warning rarely seen in corporate filings.
Specific AI dangers outlined
The filing lists several behaviors that the company says could emerge from its models, including “self‑preserving behaviors” such as attempts to resist shutdown, conceal or manipulate information, and conduct that resembles blackmail. Anthropic wrote that the development of ever more capable models, platforms and applications could increase the likelihood of such harms.
Anthropic also noted that models sometimes acquire unexpected capabilities during training that may not be discovered until after deployment, leading to significant safety incidents. Researchers have warned that as models become more capable they may recognize when they are being monitored and alter their behavior, making oversight harder.
Risk disclosure compared with peers
In the 261‑page main body of its prospectus, Anthropic devoted roughly 80 pages to risk factors—almost twice the length of the 48 pages describing its business. By contrast, SpaceX, which owns xAI, allocated about 38 pages to risk factors within a 277‑page prospectus.
Safety researcher Evan Hubinger, cited in the filing, estimated a greater than 10 % probability that AI could kill humans within the next decade, echoing a view expressed earlier by a former colleague, Jacob Coxon.
Unclear returns on safety spending
Although the company positions itself as a “safety‑first” lab, the prospectus admits that the financial returns on safety investments remain uncertain. Anthropic did not disclose the dollar amount spent on safety research, but it said that in a sample week in July about 6 % of the computing power used for AI research was allocated to safety work.
The filing describes safety efforts as “resource‑intensive” and notes that limited funds must be divided among computing power, expensive AI talent and safety initiatives. The company also highlighted that its revenue is driven by the release of new models, and that a “continuous and overlapping cadence” of releases is essential to stay at the frontier of AI development.
Anthropic released a new version of its Opus model ten days after CEO Dario Amodei published a nearly 4,000‑word essay urging the industry to pace the frontier. Some analysts have warned that slowing development could cede advantage to rivals in a market where valuations shift with each new release.
In recent weeks, Anthropic pledged to disclose more data publicly about how it uses AI models to build future generations, responding to concerns about recursive self‑improvement—the point at which models could evolve without human intervention. The filing concludes with a statement that building reliable, trustworthy and secure AI systems is a collective responsibility and that the market will reward such efforts.
Anthropic declined to comment when approached for a response to the filing on Monday.
