Anthropic leads market-implied odds for second place on the Code Arena WebDev leaderboard at end-September because its Claude Fable 5.1, released September 1, sits just behind OpenAI’s newly launched GPT-6 Astra on the community-voted Elo-style ranking for front-end coding tasks. Traders view Anthropic’s consistent strength on agentic benchmarks like SWE-Bench Pro and Terminal-Bench, combined with its Claude Code tooling updates, as likely to hold the #2 spot through the short remaining window. OpenAI’s 17% odds reflect its current #1 position after the September 3 Astra debut, while lower probabilities for Alibaba’s Qwen, Moonshot’s Kimi, and other labs stem from larger gaps on the same Pareto frontier and fewer recent coding-specific gains. With resolution imminent, any additional model drops before September 30 represent the main swing factor.

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 September 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.
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.
