Anthropic holds the strongest market-implied position for second place on the Code Arena WebDev leaderboard by end of September because OpenAI’s GPT-6 Astra launched September 3 and immediately claimed first with a 1,797 score, 35 points ahead of Anthropic’s Claude Fable 5.1 at 1,762. Traders view Anthropic’s consistent strength in agentic frontend workflows, multi-step reasoning, and tool use as likely to keep its lab in the runner-up spot amid limited near-term releases from competitors. Chinese labs such as Alibaba’s Qwen3.8 and Moonshot’s Kimi K3 posted earlier gains but now trail further back, while Meta’s recent Muse Spark 1.3 Max improved cost-performance on the Pareto frontier without displacing the top two. With roughly three weeks remaining and no confirmed major model drops expected before month-end, the current gap and historical coding benchmark patterns underpin the 78.9% implied probability for Anthropic.

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.
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".Anthropic holds the strongest market-implied position for second place on the Code Arena WebDev leaderboard by end of September because OpenAI’s GPT-6 Astra launched September 3 and immediately claimed first with a 1,797 score, 35 points ahead of Anthropic’s Claude Fable 5.1 at 1,762.
