Anthropic dominates trader sentiment at 88.5% implied probability because its Claude Mythos 5, Fable 5, and Opus 5 models currently lead independent leaderboards and the Chatbot Arena (style control on) in key areas such as reasoning, agentic coding, and overall intelligence scores as of late August 2026. Recent releases and sustained benchmark leadership have reinforced this edge ahead of the September 30 resolution, with Anthropic holding multiple top-10 spots across verified evaluations while competitors trail. Google, OpenAI, and others sit at single-digit or 50% odds due to narrower gaps on arena metrics and fewer recent capability jumps that would alter the ranking before month-end. The market aggregates skin-in-the-game views of these near-term dynamics rather than longer-term speculation.

This market will resolve according to the company which owns the model which has the highest arena rank based on the arena.ai Text Arena (Overall) (Style Control On) when the table under the "Leaderboard" tab is checked on September 30, 2026, 12:00 PM ET.
Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall with style control on (Adjustments: Style Control) and filtered for "Models" will be used to resolve this market.
Models will be ordered primarily by their leaderboard rank at the market’s check time. 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 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 first 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.
