Recent releases of Anthropic’s Claude Fable 5.1 and OpenAI’s GPT-6 Astra in early September have reshaped Code Arena WebDev standings, with GPT-6 Astra claiming the top spot at 1,797 points and Claude Fable 5.1 trailing by just 35 points on the crowdsourced Elo-style leaderboard. This narrow gap underpins Anthropic’s 62% market-implied odds for second place by end of October, as traders weigh the models’ strong performance on multi-step frontend tasks, long-context codebases, and iterative agentic workflows against rivals like Google, Meta, and Moonshot that trail further behind on the same arena. Ongoing updates to the leaderboard through October, including potential new model drops or benchmark shifts on related evals such as Vibe Code Bench or SWE-bench variants, remain key swing factors given the rapid pace of AI coding releases.

This market will resolve according to the second-highest ranked Company based on the arena.ai Code Arena | WebDev Leaderboard when the table under "Code Arena | WebDev" filtered for "Labs" is checked on October 31, 2026, 12:00 PM ET.
Results from the "Lab Rank" column under the "Code Arena | WebDev" Leaderboard tab at https://arena.ai/leaderboard/code/webdev?rankBy=labs (Overall) filtered for "Labs" 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.
AI companies will be ordered primarily by their Lab Rank at the market’s check time. If the results based on the lab ranking are ambiguous or unavailable, the relevant AI companies will be ordered according to their highest-ranking AI model in the leaderboard’s “Models” view. If two or more models are tied on rank, they will be ordered by which model is listed higher on the leaderboard. If a tie still remains, alphabetical order of AI lab/company names as listed in this market group will be used as a final tiebreaker (e.g., “Google” would be ranked ahead of “SpaceXAI”). This market will resolve based on the company that occupies second place under this ranking.
The resolution source for this market is the arena.ai Code Arena | WebDev Leaderboard. 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.
