OpenAI’s GPT-6 Astra launch on September 3 quickly claimed the top Code Arena WebDev score at 1,797, shifting trader focus to which lab will hold second place by end of October. Anthropic’s Claude Fable 5.1 and Opus variants currently sit at 1,762 and nearby, while Alibaba’s Qwen3.8-max-0902, Moonshot’s Kimi K3, and Tencent models cluster within 100–150 points on the crowdsourced Elo leaderboard for agentic frontend tasks. Chinese labs continue narrowing the proprietary gap through rapid iteration and lower-cost releases, and Meta’s Muse Spark and SpaceXAI’s Grok-4.6 remain within striking distance. With only weeks until resolution, any new model drops, benchmark updates, or sustained voting surges on Arena.ai could reorder the middle of the pack before the cutoff.

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".
