**Recent releases have reshaped the Code Arena WebDev leaderboard, creating a tight contest for third place among AI labs by end of October.** OpenAI’s GPT-6 Astra launched in early September and quickly claimed the top spot with roughly 1,797 points, narrowly ahead of Anthropic’s Claude Fable 5.1 at around 1,762, while Alibaba’s Qwen3.8-max variants and Moonshot’s Kimi K3 series sit just behind in the 1,675–1,702 range alongside strong showings from Meta’s Muse Spark models. This positions OpenAI and Anthropic as the clear frontrunners for first and second, leaving Chinese labs such as Alibaba and Moonshot, plus Meta and Z.ai, as the main contenders for third based on current community-voted Elo scores that emphasize agentic, multi-step web development tasks. Traders appear to view further rapid gains by these efficient, competitively priced models as plausible before the October cutoff, reflected in the closely matched market-implied odds and elevated “Other” probability amid ongoing model updates and potential leaderboard volatility.

This market will resolve according to the third-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 third 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".**Recent releases have reshaped the Code Arena WebDev leaderboard, creating a tight contest for third place among AI labs by end of October.** OpenAI’s GPT-6 Astra launched in early September and quickly claimed the top spot with roughly 1,797 points, narrowly ahead of Anthropic’s Claude Fable 5.1 at around 1,762, while Alibaba’s Qwen3.8-max variants and Moonshot’s Kimi K3 series sit just behind in the 1,675–1,702 range alongside strong showings from Meta’s Muse Spark models.
