Anthropic's rapid cadence with the Claude 4 family, including Opus 4.7 in April 2026 and multiple Sonnet updates, signals strong internal momentum that traders see driving a potential Claude 5 release in the Q2-Q3 window. Leaks around a powerful unreleased model codenamed Mythos and Sonnet 5 "Fennec" point to advances in reasoning, agentic capabilities, and context windows that could outpace prior versions while competing directly with GPT-5 and Gemini 3. No official confirmation exists yet, leaving room for timeline slips common in frontier large language model development, though upcoming developer conferences and benchmark releases could clarify progress and shift market-implied odds on exact timing.

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.
