Contract resolution rules

AI-assisted explanation

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.

Original resolution rules
This market will resolve to "Yes" if the next Anthropic Claude Haiku model (4.6+) added to the Arena.AI Leaderboard (https://arena.ai/leaderboard/text/overall-no-style-control) has at least the specified score at 12:00 PM ET on the calendar date following the date on which it first appears on the leaderboard. Otherwise, this market will resolve to "No". A qualifying model must have a name or model identifier that includes "Haiku" and be designated as version 4.6 or higher, regardless of capitalization or surrounding prefixes, suffixes, dates, or descriptors. For example, a version 4.6 or higher named in the same manner as Claude Haiku 4.5 would qualify, including a new whole-number generation such as Claude Haiku 5, while models whose name does not include "Haiku" or which retain a version designation below 4.6, such as Claude Haiku 4.5, including any rollout, promotion, or snapshot of it, will not qualify. Results from the "Score" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off will be used to resolve this market. This market will resolve solely based on the specified score in the Score column of the leaderboard, regardless of any underlying granular or unrounded data presented elsewhere. A model marked "AutoEval" will not be considered added to the leaderboard. Only scores displayed without the "AutoEval" label will be considered. If multiple models are added to the leaderboard on the same calendar date (ET), the highest-scoring model will be used for resolution. Models added to the leaderboard on the calendar date following the initial qualifying model's first appearance will not be considered. If a model is first added to the Arena.AI Leaderboard but is subsequently removed and not re-added, such that it is not displayed on the leaderboard at 12:00 PM ET on the calendar date following its first appearance, its appearance will not qualify as added to the Arena.AI Leaderboard. A qualifying model must be newly added to the Arena.AI Leaderboard. Whether the model was previously released, publicly accessible, in beta, or otherwise available before appearing on the leaderboard is irrelevant for this market. The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://arena.ai/leaderboard/text/overall-no-style-control. If this resolution source is unavailable at 12:00 PM ET on the calendar date following the date on which the qualifying model first appears on the leaderboard, this market will resolve based on the first subsequent instance at which such a score becomes available on the leaderboard. If it remains unavailable through the end of the seventh day after the qualifying model first appears on the leaderboard or if no qualifying model release occurs by June 30, 2027, 11:59 PM ET, this market will resolve to "No".
