Anthropic, the AI company behind Claude, has maintained a predictable cadence of model releases over the past years. The question asks whether a new model with the "Mythos" designation—potentially a major architectural advance or enhanced capability version—will be publicly released by April 30, 2026. With only 13 days remaining until the resolution date as of mid-April, the market is pricing this scenario at just 1% probability, reflecting significant skepticism that such a release would occur this month. The low odds suggest traders view either that Anthropic's roadmap doesn't include a Mythos release this month, or that any such release would come under a different name or as a pre-release. Historically, major Claude releases have been announced via Anthropic's official channels, making the market easily resolvable by checking their website, announcements, and product pages. The odds trajectory has likely remained anchored near zero throughout the market's life, as April 30 represents a hard deadline with little time for a surprise announcement. This prediction market captures near-term sentiment on Anthropic's product velocity and the likelihood of a major Claude variant reaching users before month-end.
