OpenAI’s GPT-6 Astra (Max) took the top spot on the Code Arena WebDev leaderboard in early September 2026 with a score of roughly 1797–1800, establishing a 35-plus point lead over Anthropic’s Claude Fable 5.1 (Max) at around 1762. The model’s strong results across agentic front-end tasks, including multi-step HTML/React workflows, data/analytics, and consumer-product categories, reflect recent gains in tool use and iterative coding that traders see as decisive for the end-of-September snapshot. Anthropic remains the only realistic challenger at 20.5% implied probability due to its consistent second-place standing and prior frontier coding performance, while Google, Moonshot, Meta, and other labs trail further behind on the same benchmark. With resolution less than two weeks away and no major competing releases confirmed before month-end, trader consensus has consolidated around OpenAI’s current leaderboard position as the primary driver of the 78% market-implied odds.

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 (Max) took the top spot on the Code Arena WebDev leaderboard in early September 2026 with a score of roughly 1797–1800, establishing a 35-plus point lead over Anthropic’s Claude Fable 5.1 (Max) at around 1762.
