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 launch of Claude Fable 5—the first publicly available Mythos-class large language model with safeguards—and the limited-access Claude Mythos 5 reset the frontier benchmark in reasoning, coding, and cybersecurity tasks. Subsequent U.S. government restrictions and a partial July redeployment to trusted partners for defensive cyber use have highlighted ongoing safety and regulatory hurdles that could delay broader follow-on releases. Traders are weighing Anthropic’s rapid iteration pace against competitive pressure from OpenAI, Google DeepMind, and xAI, which are advancing comparable models amid tightening export controls and benchmark scrutiny. Key catalysts ahead include potential announcements tied to developer conferences or earnings updates through September, with market-implied odds reflecting uncertainty over whether Anthropic can clear internal safety reviews and scale the next iteration before the end of the third quarter.
