Resolution criteria

This market resolves to YES if Anthropic officially releases a new model in the "Haiku" tier during the month of October 2026 (between October 1, 2026, and October 31, 2026, at 11:59 PM UTC). Otherwise, this market resolves to NO.

To qualify for a YES resolution, the model must meet the following conditions:

• It must be officially announced by Anthropic or listed as a generally available or publicly accessible to claude.ai, Claude Code, or API users.

• It must explicitly feature "Haiku" in its official name (e.g., Claude Haiku 5.5).

• Leaks, internal developer tests, or restricted Early Access Previews do not qualify unless the model is officially and publicly launched or made available to claude.ai, Claude Code, or API users within the timeframe.

The primary sources of truth for this market will be the Anthropic News Blog, the model menu on claude.ai, the model menu in Claude Code, and the models listing on OpenRouter for the API.
