Anthropic released Claude Sonnet 5 on June 30, 2026, as its most agentic mid-tier model yet, delivering near-Opus performance in coding, tool use, reasoning, and autonomous agent tasks at Sonnet pricing with a 1M-token context window. This followed Sonnet 4.6 by roughly four months and positioned the model as the default across free and paid Claude plans, with introductory API rates that later became standard. Traders are watching Anthropic’s historical cadence, competitive pressure from OpenAI and Google model launches, and any signals around the next Sonnet iteration amid ongoing Opus 5 refinements and platform updates. No official timeline has been announced, leaving resolution dependent on development milestones and market positioning.

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 released Claude Sonnet 5 on June 30, 2026, as its most agentic mid-tier model yet, delivering near-Opus performance in coding, tool use, reasoning, and autonomous agent tasks at Sonnet pricing with a 1M-token context window.
