Anthropic’s recent Claude Fable 5.1 and Opus 5 releases have driven its 69.3% implied probability for second place on the Code Arena WebDev leaderboard, as these models post top or near-top Elo scores in human-voted frontend and fullstack tasks, outpacing most rivals on benchmarks like SWE-bench Verified and Terminal-Bench. OpenAI’s GPT-6 Astra launch in early September narrowed the gap but left traders assigning it just 27.3%, reflecting persistent edges for Anthropic in UI polish, agentic workflows, and consistent arena voting margins. Lower-priced Chinese models and others sit near 50% or below due to limited verified WebDev Arena data and narrower leads in real-world coding evals. With resolution tied to end-September leaderboard standings, any late model update or voting surge could shift the crowded field.

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.
