Anthropic’s July 24 release of Claude Opus 5 drives the current market consensus, with its high and max effort configurations holding 91% combined implied probability as the leading AI model on September 7. The model delivers step-change gains in deep reasoning, long-horizon agentic tasks, and test-time compute scaling while matching much of Fable 5’s frontier performance at Opus-tier pricing and efficiency. It became the default on Claude Max plans, supports a 1-million-token context window, and shows state-of-the-art results on coding and enterprise benchmarks. With no comparable releases from OpenAI, Google, or other labs in the past month and the September 7 resolution date approaching, traders see limited near-term upside for older Opus 4.6 variants or competing models to overtake it.

Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off (Adjustments: None) and filtered for "Models" will be used to resolve this market.
Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score.
No new model will be added to this market after market creation. Any model not explicitly listed in this market will be encompassed under the "Other" option.
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 model names as listed in this market group (full string, including suffixes such as “-high” and “-max”) will be used as a final tiebreaker (e.g., if two models remain tied, “claude-opus-5-high” would be ranked ahead of “claude-opus-5-max”). This market will resolve to the model that comes first according to this order.
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".
