Anthropic has not officially released Claude 5 or any variant as of early April 2026, despite persistent leaks since February spotlighting Sonnet 5 "Fennec" in Google Vertex AI logs and Opus 5 "Mythos" internals suggesting imminent general availability with lower inference costs and enhanced benchmarks. The firm prioritizes incremental Claude 4 updates, including Opus 4.6's sabotage risk assessments approaching AI Safety Level 4 for autonomous R&D, amid fierce competition from OpenAI's GPT advancements and Google's Gemini iterations. Trader sentiment hinges on Anthropic's historical mid-year model cadences, with potential catalysts like earnings previews or developer previews poised to shift implied probabilities for a phased rollout starting with cost-efficient Sonnet upgrades.

For this market to resolve to "Yes," Claude 5 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 clearly defined and publicly announced by Anthropic as being accessible to the general public.
Claude 5 refers to a product explicitly named Claude 5 (e.g. Claude 5.0 would count), or one that is recognized as a successor to Claude 4, similar to the progression from Claude 2 to Claude 3. Products labeled as Claude 4.5 or similar will not count for this market's resolution.
