OpenAI’s GPT-6 Astra release on September 3 has driven its 76.1% market-implied odds by demonstrating strong gains in software engineering, agentic coding workflows, and enterprise adoption on benchmarks like Terminal-Bench and SWE-bench variants. Traders view the model’s large context window and tool-use performance as likely to secure the top Code Arena WebDev spot by month-end, outpacing Anthropic’s Claude Fable 5.1 (23.5%), which posted competitive but narrower leads on recent arena updates. Other labs remain near zero because their latest releases, such as Google’s Gemini 3.7 Flash or various open-weight entries, have not matched the frontier closed models on the specific WebDev agentic tasks tracked by the arena. With resolution days away, any final leaderboard shifts or undisclosed capability updates could still alter the outcome.

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".
