Anthropic holds an 78.8% implied probability as the second-best Code Arena WebDev AI lab by end-September 2026 because its Claude Opus 5 and Fable 5.1 models maintain top-tier performance on agentic frontend coding tasks, sitting just behind OpenAI’s newly launched GPT-6 Astra (1,797 points) on the Arena.ai leaderboard. Recent community-voted Elo results show Anthropic models excelling in multi-step web development workflows, multi-file reasoning, and tool use, outpacing most rivals even as OpenAI claimed the lead on September 3. Alibaba’s Qwen3.8-Max-0902 briefly led earlier in the month but trails in sustained category strength, while OpenAI’s 13.1% chance for second reflects its current #1 position. No major model releases are scheduled before month-end, leaving these relative standings as the dominant driver of trader consensus.

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.
