Claude 5 (Anthropic) release date

Question

Minor changes to the name, such as 'Claude 5 Sonnet' or 'Claude 5 Opus', or other names for a model generally expected to be called Claude 5, will count for the purpose of this market.

The model must be accessible without individual vetting or invitation — free or paid, via API or product. Open, non-selective waitlists count. Closed betas, invite-only access, researcher programs, A/B tests, and anonymous benchmark appearances do not. Country-level bans do not prevent resolution.
