Anthropic leads trader sentiment for second place on the Code Arena WebDev leaderboard by end of September because its Claude Fable 5.1 Max model holds a clear 35–40 point edge over rivals in the crowdsourced Elo rankings, which evaluate agentic, multi-step frontend and full-stack coding tasks. OpenAI’s GPT-6 Astra claimed the top spot after its early-September launch, but Anthropic’s lab depth—bolstered by strong Opus 5 variants—keeps it well ahead of the next tier. Recent Qwen3.8 and Kimi K3 updates from Alibaba and Moonshot narrowed gaps on cost-performance frontiers yet remain 100+ points behind, while other labs show minimal movement. With resolution imminent and no major new releases confirmed, the 73.7% implied probability reflects Anthropic’s durable positioning in real-world web development benchmarks.

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.
