Anthropic’s recent Claude Opus 5, Fable 5.1, and Mythos 5 releases have driven its 78.8% implied probability as the second-best Code Arena WebDev AI lab by end-September, building on consistent leadership in agentic coding benchmarks such as SWE-bench Verified and BigCodeBench. These models excel at multi-step web development workflows, large-context refactoring, and tool use, outpacing most rivals in developer adoption and real-world task completion. OpenAI’s GPT-6 Astra currently leads the live Code Arena WebDev leaderboard at 1,797 points, narrowing the gap but leaving Anthropic’s broader coding ecosystem as the clear runner-up in trader consensus. Lower-probability labs like Alibaba’s Qwen and Meta face sizable capability gaps on the same frontend and agentic tasks, with no major releases expected before resolution to close the distance.

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.
