Contract resolution rules
AI-assisted explanation
Predicts whether Kimi K3.1 Pro (or its Highspeed variant) debuts in the top 20 of the Arena.AI Text Overall leaderboard (style control off, no filters) by June 30, 2027.
Conditions for a winning outcome
A Kimi K3.1 Pro entry (including Highspeed variant, or names containing Kimi and K3.1, with optional prefixes/suffixes/labels) is displayed with a rank and no AutoEval label on the Text Arena Overall leaderboard (style control off, Models view, no filters). Its first appearance date (ET) is the date it first shows a rank. At 12:00 PM ET on the calendar date following that first appearance, its displayed rank in the Rank column is within the top 20. If the model is not displayed at that check time, that appearance does not qualify; any subsequent display starts a new first appearance. If multiple qualifying models appear the same ET date, the highest-ranking one governs. Models added on the calendar date following the initial qualifying model's first appearance are not considered. The entry must be newly added to the leaderboard.
Exclusions and exceptions
Any Kimi model not matching K3.1 Pro (e.g., Kimi K3 Max, K2.8 Preview, or later versions), entries marked AutoEval, entries without a displayed rank, models not displayed at 12:00 PM ET on the calendar date following first appearance (unless subsequently reappearing, which starts a new first appearance), models appearing on dates after June 30, 2027 11:59 PM ET, models not in the top 20 at the check time, or cases where no qualifying model appears by the deadline.
Timing & resolution
June 30, 2027, 11:59 PM ET. If a qualifying model first appears before this date, the check occurs at 12:00 PM ET on the calendar date following its first appearance. If the leaderboard is unavailable at that check time, the first subsequent available instance is used; if unavailable through 7 days after first appearance or no qualifying model is added by the deadline, resolves No.
Ambiguities in the rules
The top-20 threshold is clearly stated in the question. The model release date of October 23, 2026 is used solely for identification of the qualifying model and is not otherwise relevant to resolution.

Original resolution rules
This market will resolve to "Yes" if the next Moonshot AI Kimi K3.1 Pro model added to the Arena.AI Leaderboard (https://arena.ai/leaderboard/text/overall-no-style-control) holds a rank within the specified top ranks when the table under the "Leaderboard" tab is checked 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 be Moonshot AI's Kimi K3.1 Pro (released October 23, 2026), including its Highspeed variant, listed under a name or model identifier that includes "Kimi" and "K3.1", regardless of capitalization, hyphenation, spacing, or surrounding prefixes, suffixes, or reasoning or effort labels. For example, Kimi K3.1 Pro, Kimi K3.1 Pro Highspeed, or kimi-k3.1-pro, including with a label such as "(Max)" or "(High)", would qualify, while other models, such as Kimi K3 (Max), Kimi K2.8 Preview, or any later Kimi version, will not qualify.
Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off (Adjustments: None), in the "Models" view, and with no other filters applied will be used to resolve this market. A model debuts within the specified top ranks if its displayed rank at the check time is equal to or better than the specified rank (for example, a displayed rank of 4 is within the top 5 and the top 10). This market will resolve solely based on the specified rank in the Rank column of the leaderboard, regardless of the model's score, rank spread or confidence intervals, ranks shown under other adjustments, filters, or categories, or any underlying granular or unrounded data presented elsewhere.
A model marked "AutoEval" will not be considered added to the leaderboard. A model is considered to first appear on the leaderboard on the first calendar date (ET) on which it is displayed with a rank and without the "AutoEval" label; only such ranks will be considered. An entry listed under a preliminary, code, or placeholder name is considered newly added on the first date it is displayed under a name satisfying the model specification clause above; a renamed entry's first appearance under a qualifying name counts as its addition to the leaderboard. Each separately listed entry, including reasoning or thinking-level variants of the same model, is a distinct model for the purposes of this market, and the first qualifying entry added governs resolution.
If multiple qualifying models are added to the leaderboard on the same calendar date (ET), the highest-ranking 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 qualifying model is not displayed on the leaderboard at 12:00 PM ET on the calendar date following its first appearance, that appearance will not qualify; if the model is subsequently displayed again, the date on which it reappears will be treated as a new first appearance.
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 Arena.AI Leaderboard found at https://arena.ai/leaderboard/text/overall-no-style-control. If the leaderboard's URL, tab names, or control labels change, the equivalent default Text Overall view with style control disabled and no filters applied on arena.ai constitutes the same resolution source; such changes do not make the source unavailable. 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 the model's rank 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 is added to the leaderboard by June 30, 2027, 11:59 PM ET, this market will resolve to "No".
