View full official resolution rules
Resolves yes if any model is released to the public by Anthropic with "Mythos" in the name by 11:59 pm ET June 30th, 2026. It resolves no otherwise. A model is considered publicly released if it is released via the API, on the web app, in Claude code, or in any other place that can be reached by the general public. The model does not need to be released to all tiers of Claude subscribers. I may trade on this market. Update 2026-06-08 (PST) (AI summary of creator comment): A yes resolution will also occur if a publicly released model's system card indicates it is a Mythos class model or that it shares underlying weights with Mythos, even if the literal model name does not include "Mythos".
