Anthropic continues rapid iteration on its Claude 4 series, shipping Opus 4.6, computer use tools, and other enhancements throughout March 2026 amid five reported outages, keeping the Claude 5 launch in trader focus without an official announcement. Leaks of "Claude Mythos"—a purported next-gen model with advanced capabilities—and "Fennec" (Sonnet 5 codename) spotted in Vertex AI, alongside a recent Claude Code source leak, signal internal progress toward lower inference costs and superior agentic AI. Amid competition from OpenAI's GPT advancements, market-implied odds reflect caution on near-term release but anticipate a Q2 debut; watch Anthropic's Science Blog and X for catalysts like beta rollouts or benchmark reveals.

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.
The primary resolution source for this market will be official information from Anthropic, with additional verification from a consensus of credible reporting.
