OpenAI’s September 5 release of GPT-6 Astra (Max) has driven the 78% market-implied probability that it will lead Code Arena’s WebDev leaderboard at month-end. The model quickly posted a 1,797 score, establishing a 35-point gap over the nearest Anthropic entry and topping categories such as data analytics and consumer-product builds. Trader consensus reflects this demonstrated agentic performance in multi-step frontend workflows, while Anthropic’s 21% odds capture its still-competitive Claude variants. No subsequent model launches have narrowed the margin in the past two weeks, though any late-September update from either lab could alter final rankings before resolution.

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".
