Claude Mythos released on…?

This market will resolve according to the date (ET) on which Anthropic makes "Claude Mythos" available to the general public. Any model whose official name includes “Mythos” (e.g., Claude Mythos 1, Claude Mythos 5, Claude Mythos X) or that Anthropic officially describes as a “Mythos-class” model or similar, will qualify towards this market’s resolution. Products labeled as Claude Haiku, Sonnet, and Opus 4.7/5.0 or similar will not count for this market's resolution unless named Mythos or officially identified by Anthropic as a “Mythos-class” model. 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.
