Recent OpenAI GPT-6 Astra release has locked in the Code Arena WebDev top spot with a 1,797 Elo score, creating a tight race for second place among labs like Anthropic, Moonshot, Alibaba, and others. Trader consensus at 50% across outcomes reflects ongoing volatility in agentic coding benchmarks, where multi-step reasoning, tool use, and fullstack performance shift quickly with model updates. Anthropic’s Claude Fable 5.1 trails by just 35 points on crowdsourced votes, while cost-efficient options from Moonshot and Chinese labs challenge on Pareto frontiers. Key catalysts through November include potential new releases, expanded fullstack evaluations, and further category-specific voting that could reorder the leaderboard.

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 November 30, 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.
