On June 9, 2026, Anthropic released the Mythos-class model Claude Fable 5.
This market will resolve to "Yes" if Anthropic releases the next Mythos-class model and makes it available to the general public by the listed date (ET). Otherwise, this market will resolve to "No."
Any model whose official name includes “Mythos,” or that Anthropic officially describes as a “Mythos-class” model or similar, will qualify for this market’s resolution.
For this market to resolve to "Yes," the qualifying model (as defined above) must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must be clearly defined and publicly announced by Anthropic as being accessible to the general public.
If a qualifying model is made publicly accessible and labeled with the relevant version name within the company’s official website, this will qualify as “publicly announced”. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public under the rules will not qualify.
The primary resolution source for this market will be official information from Anthropic; however, a consensus of credible reporting will also be used.Anthropic’s September 1 announcement of Claude Mythos 5.1, an incremental update to the Mythos-class large language model with targeted gains in cybersecurity and biology benchmarks, is the dominant factor shaping trader consensus on the next release. This follows the June 2026 launch of Claude Mythos 5 (restricted via Project Glasswing) and the more widely available Fable 5 variant, which established the current capability baseline after earlier preview access. Regulatory approvals that restored limited U.S. partner access in July, combined with Anthropic’s roughly 12-week frontier cadence and ongoing emphasis on safety guardrails, underpin strong implied probability for near-term resolution. Key swing factors include potential expansions of trusted-access programs, any redefinition of “general public” availability, or competitive pressure from other labs’ model updates.
