Resolution criteria

This market resolves to YES if, at any point from August 16, 2026, through January 01, 2027 (00:00 CET), an open-weights model holds the #1 position (highest score) on the Artificial Analysis Intelligence Index (or the main LLM Leaderboard sorted by "Intelligence Index"). Otherwise, this market resolves to NO.

Note that a model has to be open weights while holding the #1 position, if a model is proprietary on initial release only releasing weights after it's no longer occupying the #1 position it does not count

Ties: If multiple models are tied for the #1 spot (same numerical index score), and at least one of the tied models is open weights, the market resolves to YES.
