OpenAI’s GPT-6 Astra, launched September 3, 2026, currently leads the Code Arena WebDev leaderboard with a 1,797 score after community-voted evaluations of agentic frontend coding and multi-step workflows, placing it 35 points ahead of Anthropic’s Claude Fable 5.1. This recent performance edge underpins OpenAI’s 57% market-implied probability while many other labs sit near 50%, reflecting tight competition and trader uncertainty over sustained leadership through October. Anthropic maintains strong historical coding benchmarks and multiple top-tier models, yet trails on the latest WebDev-specific votes. Chinese labs including Alibaba’s Qwen variants and Moonshot’s Kimi series deliver competitive results at lower price points, narrowing gaps with proprietary leaders on agentic tasks. No major releases have shifted the ordering in the past week, though further model updates before resolution could alter the ranking.

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 October 31, 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.
Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score.
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.
