**Anthropic holds a strong position for second place on the Code Arena WebDev leaderboard** due to its Claude Fable 5.1 Max model sitting at 1,762 points, just 35 behind OpenAI’s newly launched GPT-6 Astra Max at 1,797. The crowdsourced Elo-style ranking, driven by over 650,000 community votes on real-world frontend coding and agentic workflows, rewards consistent multi-step reasoning and tool use where Anthropic’s recent Opus 5 and Fable 5 series have excelled. OpenAI’s rapid ascent after the September 3 release created the current gap, but Anthropic’s depth across multiple high-performing models and sustained preference votes keep it favored at 74% implied probability for second-best lab by month-end. Other labs like Alibaba’s Qwen trail further behind with fewer votes and wider confidence intervals, while the short remaining window limits major shifts absent new releases.

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. If it becomes permanently unavailable, this market will resolve to "Other".
