2. §2Otherwise, this market will resolve to "No".
3. §3Any Anthropic Claude model newly added to the Humanity’s Last Exam results and labeled as "Opus" may qualify (e.g., claude-opus-5.1, claude-opus-5.5-thinking, claude-opus-6-preview, or similar).
4. §4Claude models labeled only as Sonnet, Haiku, Fable, Mythos, or another non-Opus variant will not qualify.
