**Claude Opus 5's July 24 release and immediate leaderboard dominance drive the market's heavy weighting toward its high and max effort variants.** Released as a cost-efficient step up from Opus 4.8 that approaches Fable 5 frontier performance on agentic coding, reasoning, and professional tasks, the model quickly topped Artificial Analysis Intelligence and Agentic indices while claiming top Arena coding boards. Traders see the high-effort (56.5% implied probability) and max-effort (34.0%) configurations as the strongest contenders for the September 7 snapshot, reflecting the model's adaptive thinking defaults, full effort ladder, and benchmark edge over recent rivals like Grok 4.6. With no major competing releases in the past month and resolution criteria tied to established leaderboards, the narrow "other" share signals sustained Anthropic momentum into early September.

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".
