• Will the next Grok model (4.7+) debut at a score of at least 1490 by June 30, 2027? — resolved “No” on 26 Sept 2026. The market resolves to Yes if a new Grok model version 4.7 or higher appears on the Arena.AI leaderboard with a score of at least 1490 at 12:00 PM ET the day after its first listing. The outcome depends solely on the specific score shown in the Text Arena Overall column, excluding any models labeled AutoEval.
• Will SpaceXAI have the best AI model at the end of September 2026? — resolved “No” on 1 Oct 2026. The market resolves by checking the arena.ai Text Arena leaderboard on September 30, 2026, at 12:00 PM ET. The outcome depends on which company owns the model ranked highest in the 'Text Arena | Overall' section with style control off. Readers often mistake the resolution source, assuming it relies on general industry reputation or other benchmarks instead of this specific website's data.
