OpenAI’s GPT-6 Astra recently claimed the top spot on Code Arena’s WebDev leaderboard with 1797 points, ahead of Anthropic’s Claude Fable 5.1 Max and Opus 5 Max, shifting trader focus to which lab will finish second by end of September. Anthropic’s strong implied probability reflects its models’ consistent edge in agentic, multi-file web development tasks, including database integration, authentication, and iterative fullstack workflows that mirror real SWE-bench performance. Ongoing human preference votes continue to favor Claude variants for reliability in complex frontend-backend scenarios, while lower-priced challengers from Alibaba, Moonshot, and others trail on the aggregated leaderboard. With resolution tied directly to arena.ai rankings and rapid model iteration possible, fresh releases or vote surges remain key swing factors for the final ordering.

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.
