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 release of Claude Fable 5—a safeguarded Mythos-class large language model exceeding Opus capabilities—alongside the limited-access Claude Mythos 5 via Project Glasswing has reset the competitive timeline, with traders now focusing on follow-on releases from OpenAI, Google DeepMind, or xAI. The full Mythos tier's cybersecurity and biological risks prompted Anthropic's guardrails and recent government-directed restrictions, creating uncertainty around broader availability and pressuring rivals to demonstrate comparable agentic performance or safety benchmarks. Key near-term catalysts include developer conferences, potential model previews, and Anthropic's IPO preparations, which incentivize capability demonstrations while highlighting how quickly product timelines and regulatory scrutiny can shift outcomes in this high-stakes AI race.
