Resolution rules
This market will resolve to "Yes" if the next OpenAI GPT Luna model 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 "GPT" and "Luna" and be designated as version 5.7 or higher, regardless of capitalization or surrounding prefixes, suffixes, dates, or descriptors. For example, a version 5.7 or higher named in the same manner as GPT-5.6 Luna would qualify, including a new whole-number generation such as GPT-6 Luna or an Astra-branded release meeting these criteria, while models whose name does not include "Luna" or which retain a version designation below 5.7, such as GPT-5.6 Luna, GPT-5.6 Sol, GPT-5.6 Terra, or GPT-6 Astra (released September 4, 2026), will not qualify. Fine-tunes, modes, or restricted-access variants of an existing version, such as GPT-5.6-Cyber or GPT-5.6 Sol Ultrafast, 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…
