Claude Opus 5's July 24 release and subsequent benchmark dominance drive the market's leading claude-opus-5-max odds at 64.5%. The model tops Artificial Analysis Intelligence and Agentic indices while claiming Arena coding crowns in web development and agent tasks, reflecting strong trader consensus on its reasoning and long-horizon capabilities relative to prior Opus variants. Qwen3.8-Max's August 3 launch with 2.4 trillion parameters and competitive coding scores supports its 48.5% position as the freshest challenger, though it trails Anthropic models on key leaderboards. Older Claude variants like opus-4-6-thinking remain in contention amid ongoing evaluation of feature thresholds for the August 24 resolution.

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.
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 “-thinking”) will be used as a final tiebreaker (e.g., if two models remain tied, “claude-opus-4-6” would be ranked ahead of “claude-opus-4-6-thinking”). 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".
