OpenAI's GPT-6 Astra Max currently leads the Code Arena WebDev leaderboard with the highest arena scores around 1800 as of mid-September 2026, reflecting strong performance in agentic coding workflows, multi-step reasoning, and image-to-code tasks that define the benchmark. This positions the company as the market favorite at 75% implied probability. Anthropic's Claude Fable 5.1 Max sits close behind at roughly 1758 points after a brief early-September surge to the top spot, sustaining its 25% odds. Other labs including Moonshot's Kimi K3, Alibaba's Qwen variants, and Meta trail further back on the Pareto frontier despite prior leads, as recent model updates and voting volume have not shifted the consensus. With resolution just weeks away, traders are weighing OpenAI's sustained edge against potential late releases or leaderboard volatility in frontend web development benchmarks.

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 currently leads the Code Arena WebDev leaderboard with the highest arena scores around 1800 as of mid-September 2026, reflecting strong performance in agentic coding workflows, multi-step reasoning, and image-to-code tasks that define the benchmark.
