This market will resolve to "Yes" if Anthropic's next Claude Sonnet model is made available to the general public by the specified date (ET). Otherwise, this market will resolve to "No." Claude Sonnet refers to a model by Anthropic explicitly named Sonnet. Qualifying models include Claude Sonnet 5.1, Claude Sonnet 5.5, Sonnet 6, or any other Sonnet variants. Models under any other name, such as Opus, Haiku, Fable, or Mythos, will not qualify, unless the model is explicitly and officially named Sonnet by Anthropic. 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 be either clearly defined and publicly announced by Anthropic as being accessible to the general public or otherwise made publicly accessible and explicitly labeled within 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 release cadence for Claude Sonnet models, with Sonnet 5 launched June 30, 2026, as the most agentic mid-tier large language model yet, drives current trader sentiment around the next version. Sonnet 5 emphasizes autonomous tool use, planning, and coding performance close to Opus 4.8 at lower cost, following Sonnet 4.6 in February and Sonnet 4.5 in September 2025. This roughly four-month cycle, combined with competitive pressure from OpenAI and Google on agentic benchmarks and pricing, shapes expectations for the subsequent release. Key catalysts include potential announcements tied to developer conferences, API updates, or responses to rival model launches, though no firm timelines have been confirmed.
