This market will resolve according to the second-highest ranked Company based on the arena.ai Text Arena (Overall) (Style Control On) when the table under the "Leaderboard" tab filtered for "Labs" is checked on September 30, 2026, 12:00 PM ET. Results from the "Lab Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall?rankBy=labs with style control on (Adjustments: Style Control) and filtered for "Labs" will be used to resolve this market. 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 their Arena score, including any underlying, unrounded, granular values reflected in the data below 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., if the two models are tied by exact arena score, “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 Text Arena (Overall). 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".
Meta leads trader consensus for the #2 spot on the arena.ai Text Arena leaderboard with Style Control On by September 30, 2026, amid a tight race with Google, unnamed labs, and others clustered near 50% implied probability. Recent early-September releases—OpenAI’s GPT-6 Astra, Anthropic’s Claude Fable 5.1 and Mythos 5.1, Meta’s Muse Spark 1.3, and Google’s Gemini 3.8 Flash—have intensified competition on coding, agentic tasks, and benchmark gains, keeping the field fluid behind the presumed leader. Meta’s open-weight iteration pace and developer ecosystem support its edge, while Google benefits from platform integration and scale; rapid model fatigue and shifting arena scores underscore how small benchmark edges or adoption shifts could still reorder the ranking before resolution.
