OpenAI’s GPT-6 Astra launch on September 3 quickly claimed first place on Code Arena’s WebDev leaderboard with 1,797 points by September 5, creating a clear separation that positions Anthropic’s Claude Fable 5.1-max (1,762 points) as the strong consensus favorite for second by month-end. The crowdsourced Elo system, driven by over 650,000 human votes on iterative frontend and agentic coding tasks, rewards Anthropic’s edge in multi-step reasoning and real-world web development workflows. Chinese labs such as Alibaba’s Qwen variants and Moonshot’s Kimi trail further behind despite recent gains that narrowed gaps with open models, while OpenAI’s prior releases and other major labs sit well back on the current rankings, leaving limited room for shifts before the September 30 resolution.

This market will resolve according to the second-highest ranked Company based on the arena.ai Code Arena | WebDev Leaderboard when the table under "Code Arena | WebDev" filtered for "Labs" is checked on September 30, 2026, 12:00 PM ET.
Results from the "Lab Rank" column under the "Code Arena | WebDev" Leaderboard tab at https://arena.ai/leaderboard/code/webdev?rankBy=labs (Overall) filtered for "Labs" will be used to resolve this market.
AI companies will be ordered primarily by their Lab Rank at the market’s check time. If the results based on the lab ranking are ambiguous or unavailable, the relevant AI companies will be ordered according to their highest-ranking AI model in the leaderboard’s “Models” view. 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 AI lab/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 second place under this ranking.
