**Anthropic leads trader consensus at 78.8% implied probability for second place on the Code Arena WebDev leaderboard by September 30 because its Claude Fable 5.1 model sits just 35 points behind OpenAI’s newly launched GPT-6 Astra, which took the top spot at 1,797 after its September 3 release.** The crowdsourced Elo-style arena evaluates agentic frontend coding workflows with multi-step reasoning and tool use across more than 650,000 votes. Anthropic’s strong showing in iterative web development tasks has held the second slot amid rapid leaderboard shifts, including earlier gains by Alibaba’s Qwen and Moonshot’s Kimi models. With resolution less than three weeks away, further model updates or sustained voting patterns could narrow or widen the gap before the final lab ranking is locked.

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.
