This market will resolve to "Yes" if the next model released by xAI has at least the specified score on the Arena.AI Leaderboard (arena.ai/leaderboard/text) when the table under the "Leaderboard" tab is checked on the date after the day of the release, 12:00 PM ET. Otherwise, this market will resolve to "No". Results from the "Score" column under the "Text Arena | Overall" Leaderboard tab at https://lmarena.ai/leaderboard/text with style control off will be used to resolve this market. If no qualifying score for the specified model is available on the Arena.AI Leaderboard at 12:00 PM ET following the date of the release, this market will resolve based on the first subsequent instance at which such a score becomes available on the leaderboard. If no qualifying score becomes available by the end of the seventh day following the day of the model’s release, or if no qualifying model release occurs by December 31, 2026, 11:59 PM ET, this market will resolve to "No". If multiple models are released on the same calendar date or if multiple variants of the specified model appear on the Arena.AI Leaderboard at the relevant check time (e.g., base, “Thinking,” or “Instant”), the highest-scoring variant will be used for resolution. A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must be either clearly defined and publicly announced as being accessible to the general public or otherwise made publicly accessible and explicitly labeled within the company’s official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify. The resolution source for this market is the Chatbot Arena LLM Leaderboard found at arena.ai/leaderboard/text. If this resolution source is unavailable at 12:00 PM ET following the date of the release, 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 a qualifying release, it will resolve to "No".xAI's accelerated training cadence at the Colossus supercluster drives trader optimism for its next large language model beyond Grok 4.3 to deliver a strong debut on the Arena.ai Text Leaderboard, where Elo scores gauge real-world user preferences. Elon Musk revealed on April 18 that a 1 trillion-parameter base model finished initial training days later, heralding major gains in coding, long-context handling, and skills, with improved bases rolling out biweekly from the SpaceXAI factory. Recent multimodal advances, including Grok Voice Think Fast 1.0 topping the Tau Voice Bench on April 23 and voice cloning API launch on May 1, underscore xAI's momentum amid fierce rivalry from OpenAI's GPT series and Anthropic's Claude. Watch for imminent model release announcements, as debut Elo will hinge on blind user battles against entrenched leaders like prior Grok 4.1's 1483 peak.
