**Moonshot and Alibaba currently lead trader sentiment for second place on the arena.ai Code Arena WebDev leaderboard by end-October, with implied probabilities of 23% and 21.5% respectively, reflecting their models' strong recent performance just behind Anthropic's top-ranked claude-opus-5-max.** Recent leaderboard snapshots (as of late August 2026) show Moonshot’s Kimi K3 Max at ~1674 and Alibaba’s Qwen3.8 Max at ~1669—narrowly trailing the leader while outperforming OpenAI, Google, and others in agentic web development tasks. These scores come from crowdsourced human votes on real fullstack workflows involving multi-step reasoning, tool use, databases, authentication, and deployments in the evolving Code Arena environment. Competitive dynamics center on rapid iteration by Chinese labs (Moonshot and Alibaba) delivering cost-effective gains in coding benchmarks, versus established players’ ongoing releases. Google’s Gemini 3.7 Flash, for example, climbed sharply after its mid-August update. The close 45–55% range between the top two contenders underscores uncertainty from frequent model drops, vote accumulation, and category-specific strengths in frontend/backend integration. Traders view upcoming releases and sustained leaderboard momentum through October as the key swing factors in this tight race.

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 October 31, 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.
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.
