OpenAI's GPT-6 Astra Max currently tops the Code Arena WebDev leaderboard with the highest scores around 1800, driving its 66% implied probability for best model by end-September. Released September 3, the model pulled ahead of Anthropic's Claude Fable 5.1 (1758) on agentic web development tasks involving multi-step reasoning and tool use, widening the gap over competitors like Alibaba's Qwen and Moonshot's Kimi variants. Anthropic holds a 31% chance after Fable 5.1's prior lead and strong coding benchmarks, though traders note limited time for a counter-release before month-end. Lower odds for Google, Meta, and others reflect their trailing positions amid rapid proprietary frontier advances in web coding performance.

Results from the "Rank" column under the "Code Arena | WebDev" Leaderboard tab at https://arena.ai/leaderboard/code/webdev (Overall) filtered for "Models" will be used to resolve this market.
Models will be ordered primarily by their leaderboard rank at the market’s check time. 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 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 first 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".
