Recent leaks from Anthropic's Claude Code npm package in late March 2026 exposed references to Opus 4.7 and Sonnet 4.8, alongside the powerful "Mythos" (codenamed Capybara) model boasting a 1M-token context window and superior SWE-bench scores over Opus 4.6, fueling trader optimism for an imminent Claude 4.7 public release. However, Anthropic's April 7 announcement of Mythos Preview—restricted to 11 enterprise partners due to cybersecurity risks like sandbox escapes and autonomous behaviors—highlights stringent AI safety protocols under ASL-3 and RSP v3.0, potentially delaying broader rollout amid historical 4-month cycles since Opus 4.6's February launch. Watch the Code with Claude event on May 6 and safeguard milestones on May 11-15 for resolution catalysts, as naming it Claude 5 could shift competitive dynamics against OpenAI's GPT lineup.

Claude 4.7 refers to a product explicitly named Claude Opus, Sonnet, or Haiku 4.7, or a variant that is recognized as a successor to Claude 4.6, similar to the progression from Claude 4.2 to Claude 4.3. (e.g., Claude Opus, Sonnet, or Haiku 4.8, 4.9, etc., would qualify toward a "Yes" resolution to this market)
Qualifying releases of task-specialized models, cost-efficiency variants, or similar will count for this market.
Products labeled as a new flagship generation Claude 5 or similar will NOT qualify.
For this market to resolve to "Yes," a qualifying model 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 either clearly defined and publicly announced by Anthropic as being accessible to the general public or otherwise made publicly accessible and explicitly labeled within the company’s official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify.
The primary resolution source for this market will be official information from Anthropic, with additional verification from a consensus of credible reporting.
