Anthropic holds a dominant 77.8% implied probability as the second-best Code Arena WebDev AI lab by end of September, reflecting its Claude Fable 5.1 and Opus 5 models' consistent second-place ranking behind OpenAI's newly launched GPT-6 Astra on the crowdsourced Elo-style leaderboard. The September 3 release of Astra quickly claimed the top spot with 1,797 points, but Anthropic's agentic coding strengths in multi-step frontend workflows, tool use, and iterative development have kept its models within striking distance at 1,762. Other labs trail significantly, with Alibaba, Moonshot, and Meta models clustered lower amid fewer recent capability jumps. Traders appear to view Anthropic's established edge in complex web dev tasks as stable through month-end absent major new 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 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.
