**Anthropic holds the strongest position for second place on the Code Arena WebDev leaderboard by end of October.** OpenAI’s GPT-6 Astra, released September 3, leads with 1,797 points on the crowdsourced Elo system evaluating agentic frontend and full-stack web development tasks, while Anthropic’s Claude Fable 5.1 sits just 35 points behind at 1,764. Anthropic’s depth across Fable 5.1 and Opus 5 variants supports its 63% market-implied odds, as the lab’s consistent multi-step reasoning and tool-use performance has kept it competitive despite OpenAI’s recent edge. Chinese labs like Alibaba’s Qwen and Moonshot’s Kimi trail further back in the 1,670–1,685 range, with limited near-term catalysts expected to close the gap before resolution. The short seven-week window favors the current top-two proprietary models remaining stable.

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 October 31, 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.
Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score.
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".**Anthropic holds the strongest position for second place on the Code Arena WebDev leaderboard by end of October.** OpenAI’s GPT-6 Astra, released September 3, leads with 1,797 points on the crowdsourced Elo system evaluating agentic frontend and full-stack web development tasks, while Anthropic’s Claude Fable 5.1 sits just 35 points behind at 1,764.
