Anthropic's April 7 announcement of Claude Mythos Preview—their most capable frontier model to date, available only as a gated research preview for defensive cybersecurity—marks the latest step in rapid 2026 iteration following Opus 4.6 and Sonnet 4.6 launches in February. March leaks revealed Mythos (potentially Claude 5) as a step-change in coding, reasoning, and agentic capabilities, with significant cybersecurity risks prompting restricted access and no public rollout yet. This fuels trader consensus on imminent public release amid intensifying competition from OpenAI's GPT-5 rumors and xAI's Grok advances. Watch for full API availability or developer conference reveals, as model naming and deployment criteria will dictate resolution.

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.
