Anthropic's pattern of staggered releases drives current trader focus on the next Claude Haiku, as the latest version (Haiku 4.5) launched in October 2025 while Sonnet 5, Opus 5, and Fable 5 arrived in mid-2026. The company typically positions Haiku as the fastest, lowest-cost tier with near-frontier capabilities, often updating it after major Sonnet or Opus iterations to balance performance, speed, and pricing. No official timeline or announcement exists yet for a Haiku 5 refresh, though Anthropic has signaled ongoing work on smaller models to support agentic workflows and cost-efficient scaling. Traders watch for developer conferences, API updates, or competitive moves from rivals like OpenAI and Google that could accelerate an announcement before year-end.

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.
