OpenAI holds the top position on the Code Arena WebDev leaderboard with its GPT-6 Astra model at 1800 points, ahead of Anthropic’s Claude Fable 5.1 Max at 1758, driving the 67.9% market-implied probability for OpenAI versus 31.5% for Anthropic. The edge stems from GPT-6 Astra’s recent release and stronger performance across agentic front-end coding tasks that reward multi-step reasoning and tool use. Anthropic’s early-September Fable 5.1 update briefly narrowed the gap but has not overtaken the new OpenAI leader. With no major model launches scheduled before month-end and only minor leaderboard fluctuations expected from additional votes, trader consensus favors OpenAI maintaining the lead through the final days of September. Lower-probability outcomes reflect the wide performance margin separating the two frontrunners from other labs.

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 holds the top position on the Code Arena WebDev leaderboard with its GPT-6 Astra model at 1800 points, ahead of Anthropic’s Claude Fable 5.1 Max at 1758, driving the 67.9% market-implied probability for OpenAI versus 31.5% for Anthropic.
