OpenAI’s early-September launch of GPT-6 Astra locked in the Code Arena WebDev top spot with a 35-point lead, while Anthropic’s Claude Fable 5.1 and Opus 5 models hold a clear second. Trader consensus for third place remains fragmented around 50% implied odds across multiple labs because Chinese models from Alibaba (Qwen variants) and Moonshot (Kimi K3) sit just 100–130 points behind on the lab-aggregated leaderboard, with strong showings in agentic, multi-step frontend and full-stack tasks. Z.ai, DeepSeek, Meta, and Google trail closely enough that any near-term model update or arena vote surge could reorder the middle pack before November resolution. Poolside, Mistral, and smaller labs trade at lower odds due to larger gaps in demonstrated web-dev agent performance and recent release cadence.

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".
