This market will resolve according to the calendar date (ET) on which Anthropic's next Mythos-class model is made available to the general public. 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. A qualifying model 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 either be clearly defined and publicly announced by Anthropic as accessible to the general public, or otherwise be made publicly accessible and explicitly labeled on the company's official website. 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 will not qualify. The primary resolution source for this market will be official information from Anthropic, with additional verification from a consensus of credible reporting.Anthropic’s next Mythos-class model faces a fragmented release window because the lab continues to prioritize additional safety classifiers and U.S. government approvals after the June 9 launch of Claude Mythos 5 and the safer Fable 5 variant. Recent limited expansions, including August integration of Mythos 5 into Claude Security tools for partner code scanning, signal accelerating internal readiness without full public clearance. Traders weigh this against competitive pressure from OpenAI’s restricted GPT-5.6 cybersecurity models and Chinese labs nearing similar agentic and cyber capabilities, which could force faster timelines. The near-even odds on early-to-mid September dates reflect uncertainty over final validation milestones rather than doubt about an imminent release, with historical three-to-five-month cadence from prior frontier launches providing the main anchor.
