OpenAI's GPT-6 Astra release in early September secured the top spot on the Code Arena WebDev leaderboard with a 1,797 score, outpacing Anthropic's Claude Fable 5.1 by 35 points on agentic coding tasks that test multi-step reasoning, tool use, and iterative front-end web development. This performance shift from prior Anthropic dominance explains the 68% market-implied odds for OpenAI versus 31% for Anthropic, as community votes reflect real gains in large language model capabilities for practical web tasks. With resolution imminent at month's end, limited time remains for new model launches or benchmark updates to alter the current trader consensus on frontier AI coding performance.

This market will resolve according to the company that owns the model that has the highest rank based on the arena.ai Code Arena | WebDev Leaderboard when the table under "Code Arena | WebDev" filtered for "Models" is checked on September 30, 2026, 12:00 PM ET.
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".OpenAI's GPT-6 Astra release in early September secured the top spot on the Code Arena WebDev leaderboard with a 1,797 score, outpacing Anthropic's Claude Fable 5.1 by 35 points on agentic coding tasks that test multi-step reasoning, tool use, and iterative front-end web development. This performance shift from prior Anthropic dominance explains the 68% market-implied odds for OpenAI versus 31% for Anthropic, as community votes reflect real gains in large language model capabilities for practical web tasks. With resolution imminent at month's end, limited time remains for new model launches or benchmark updates to alter the current trader consensus on frontier AI coding performance.
