Full rules

As written on Polymarket for “Claude 6 released by June 30, 2027?”.

1. §1This market will resolve to "Yes" if Anthropic's Claude 6 model is made available to the general public between market creation and the specified date (ET).
2. §2Otherwise, this market will resolve to "No".
3. §3A qualifying model must have a name or model identifier that includes "Claude" and be designated as version 6 or higher, regardless of capitalization or surrounding prefixes, suffixes, dates, or descriptors.
4. §4Any of Anthropic's general-purpose model families qualifies, including Fable, Opus, Sonnet, Haiku, or a successor general-purpose family, provided the version designation of 6 or higher appears in the name or model identifier.
5. §5For example, Claude Fable 6, Claude Opus 6, Claude Sonnet 6, or a later version such as Claude Fable 6.1 or Claude 7 would qualify, while models that retain a version designation below 6, such as Claude Fable 5.1 or Claude Opus 5, and models that do not carry an explicit version number of 6 or higher in their name or identifier, regardless of how they are described or positioned, will not qualify.
6. §6A Mythos-branded release available only through Anthropic's verification or trusted-access programs, and task-specific products or restricted lines such as Claude Code, Claude Gov, or Claude Security, will not qualify on their own.
7. A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups.
