Anthropic's most recent Haiku release, Claude Haiku 4.5, launched on October 15, 2025, delivering near-Sonnet 4 coding and agentic performance at lower cost and higher speed for latency-sensitive uses. Since then, the company has advanced its larger models through multiple iterations, including Sonnet 5 in June 2026, Opus 5 in July, and Fable 5.1 plus Mythos 5.1 in early September, widening the capability gap and leaving Haiku 4.5 as the sole lagging tier. No official announcements, system cards, or credible leaks point to an imminent Haiku 4.6 or 5 successor, though retirement notices for the current model reference a floor no sooner than October 2026. Trader sentiment reflects uncertainty around Anthropic's internal priorities and typical small-model refresh cycles amid competitive pressure from other labs on efficient large language models.

This market will resolve to "Yes" if Anthropic's next Claude Haiku model is made available to the general public by the specified date (ET). Otherwise, this market will resolve to "No."
Claude Haiku refers to a model by Anthropic explicitly named Haiku. Qualifying models include Claude Haiku 4.6, Claude Haiku 5.0, Haiku 5, or any other Haiku variants. Models under any other name, such as Sonnet, Opus, Fable, or Mythos, will not qualify, unless the model is explicitly and officially named Haiku 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 most recent Haiku release, Claude Haiku 4.5, launched on October 15, 2025, delivering near-Sonnet 4 coding and agentic performance at lower cost and higher speed for latency-sensitive uses.
