Anthropic holds a commanding lead in the second-place outcome at 63.8% implied probability, driven by its Claude Fable 5.1 and Opus 5 models maintaining consistent second-place Elo scores on the arena.ai Code Arena WebDev leaderboard behind OpenAI’s newly launched GPT-6 Astra. The September 3 release of GPT-6 Astra, which quickly established an 1,800-point lead, has clarified the top spot and left Anthropic’s frontier models as the primary challenger in agentic frontend coding tasks involving multi-step reasoning and tool use. With resolution imminent at month-end and limited new model drops reported in the past week, trader consensus reflects Anthropic’s demonstrated strength in real-world web development benchmarks while acknowledging the narrow gap that any surprise update could still close.

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.
