Anthropic holds a clear lead in trader sentiment for second place on the Code Arena WebDev leaderboard by end of October, driven by Claude models' consistent strength in frontend and UI-focused coding tasks on the crowdsourced arena. Recent independent benchmarks such as SWE-bench Verified and Vibe Code Bench show Anthropic variants outperforming rivals in agentic web development workflows, even as OpenAI's GPT-6 Astra claimed the top spot in early September. Lower odds for OpenAI, Moonshot, and others reflect narrower edges in human preference votes and higher uncertainty around rapid model iterations. Key catalysts ahead include any late-October releases or leaderboard updates that could shift relative rankings before resolution.

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.
Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score.
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. If it becomes permanently unavailable, this market will resolve to "Other".
