Trader consensus on the Polymarket reflects a tight race between Claude Opus 5 configurations, with claude-opus-5-high holding a slim 41.5% implied probability edge over claude-opus-5-max at 32.5%. This positioning stems from Anthropic’s July 2026 Opus 5 launch, which introduced adjustable effort settings allowing optimization between intelligence and token efficiency on benchmarks like Frontier-Bench and ARC-AGI 3. The high and max variants compete on demonstrated gains in agentic coding and knowledge work versus higher costs at peak settings, while recent August leaderboards confirm Opus 5’s frontier positioning overall. Key upcoming catalysts include any new capability demonstrations before the September 7 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.
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".
