Anthropic’s June 9, 2026 release of the safeguarded Claude Fable 5 for public use alongside restricted Claude Mythos 5 via Project Glasswing reset the release cadence for its top-tier Mythos-class large language models, which top benchmarks in agentic coding, reasoning, and cybersecurity tasks. Traders now price a follow-on model at 74 percent odds by September 9 and 87 percent by month-end, reflecting the lab’s typical 3–5 month frontier cycle amid intensifying competition from OpenAI’s GPT series and Google’s Gemini models. Key drivers include ongoing safety evaluations for high-risk capabilities, compute allocation priorities, and the absence of new official announcements or credible leaks since the summer launch. A new Opus model carries 96 percent odds by year-end, underscoring expectations for continued rapid iteration once safeguards mature.

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 June 9, 2026 release of the safeguarded Claude Fable 5 for public use alongside restricted Claude Mythos 5 via Project Glasswing reset the release cadence for its top-tier Mythos-class large language models, which top benchmarks in agentic coding, reasoning, and cybersecurity tasks.
