This market will resolve according to the second-highest ranked Company based on the arena.ai Agent Arena Leaderboard when the table under "Agent Arena" filtered for "Labs" is checked on September 30, 2026, 12:00 PM ET. Results from the "Rank" column under the "Agent Arena" Leaderboard tab at https://arena.ai/leaderboard/agent filtered for "Labs" will be used to resolve this market. Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score. AI companies will be ordered primarily by their Lab Rank at the market’s check time. If the results based on the lab ranking are ambiguous or unavailable, the relevant AI companies will be ordered according to their highest-ranking AI model in the leaderboard’s “Models” view. If two or more models are tied on rank, they will be ordered by which model is listed higher on the leaderboard. If a tie still remains, alphabetical order of AI lab/company names as listed in this market group will be used as a final tiebreaker (e.g., “Google” would be ranked ahead of “SpaceXAI”). This market will resolve based on the company that occupies second place under this ranking. The resolution source for this market is the arena.ai Agent Arena Leaderboard. If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and will resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve to "Other".
Trader consensus currently positions Moonshot narrowly ahead of OpenAI for second-best AI agent lab by end of September, with SpaceXAI and Anthropic close behind, as implied probabilities reflect incremental gains in autonomous task execution and multi-step reasoning benchmarks. Recent model updates emphasizing tool use, memory persistence, and real-world interaction have sharpened differentiation among labs, while regulatory scrutiny on AI safety and developer ecosystem momentum continue to influence positioning. Upcoming developer conferences and capability demonstrations in the next six weeks represent key swing factors that could shift sentiment among these closely matched contenders.
