Claude Opus 5's July 24 release drives the current market tilt, with its variants leading due to strong benchmark results on agentic coding, reasoning, and tasks like Frontier-Bench and SWE-bench, where it approaches or matches the more expensive Claude Fable 5 at half the cost. Traders favor the high and max effort settings for their test-time compute scaling and proactive verification capabilities, which have positioned Opus 5 as the practical frontier choice in recent WebDev Arena and coding leaderboards. No major competing releases have shifted sentiment since mid-August, leaving limited room for "other" outcomes or older Opus 4.6 variants unless new model announcements emerge before September 7.

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".
