Trader sentiment on Anthropic's Claude 5 release hinges on persistent leaks and rapid model iteration, with Sonnet 5 "Fennec" launching in early February 2026, but the full Claude 5 family—including rumored Opus 5 "Mythos"—still unreleased amid safety concerns from a March data exposure. Recent competition from OpenAI's GPT-5.5 rollout has spotlighted Claude's current performance gaps, prompting Anthropic's April 23 admission of issues and fixes in Opus 4.7. No official Claude 5 announcement in the past 30 days; traders eye mid-2026 windows like May-June, watching for developer conference reveals or API previews that could signal public availability and shift large language model leadership.

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.
