Screened using the explicit question date; payout timing still follows the rules.
Contract resolution rules
Market resolves Yes if the next Claude Haiku model (4.6+) newly added to the Arena.AI Leaderboard scores at least 1420 at 12:00 PM ET the day after first appearance; otherwise No. No qualifying model by June 30, 2027, 11:59 PM ET also resolves No.
Conditions for a winning outcome
Yes if: (1) a model with name/identifier including 'Haiku' and version 4.6 or higher (e.g., Claude Haiku 5) is newly added to the Arena.AI Leaderboard at https://arena.ai/leaderboard/text/overall-no-style-control; (2) it is not marked 'AutoEval'; (3) its Score column value under 'Text Arena | Overall' tab (style control off) is at least 1420 at 12:00 PM ET on the calendar date following its first appearance; (4) if multiple models are added on the same calendar date (ET), the highest-scoring model is used; (5) if the leaderboard is unavailable at that time, resolution uses the first subsequent available score, up to 7 days after first appearance.
Exclusions and exceptions
No if: (1) no qualifying model appears by June 30, 2027, 11:59 PM ET; (2) the qualifying model's score at the specified time is below 1420; (3) the model is marked 'AutoEval'; (4) the model's name does not include 'Haiku' or its version is below 4.6 (including Claude Haiku 4.5 or any snapshot/rollout of it); (5) the model is first added but then removed and not re-added by 12:00 PM ET the next calendar day; (6) models added to the leaderboard on the calendar date following the initial qualifying model's first appearance will not be considered; (7) the leaderboard remains unavailable through the end of the seventh day after the qualifying model first appears.
Timing & resolution
The score is measured at 12:00 PM ET on the calendar date following the date the qualifying model first appears on the leaderboard. If the leaderboard is unavailable then, resolution uses the first subsequent available score, up to 7 days after first appearance. If no qualifying model appears by June 30, 2027, 11:59 PM ET, the market resolves No.
Ambiguities in the rules
No concrete ambiguity identified. The rules specify the resolution source, score column, style control off, exclusion of AutoEval, treatment of multiple same-day additions, exclusion of models added on the day after the qualifying model's first appearance, removal/re-addition condition, and the deadline for no qualifying model.
