Recent model releases have intensified competition for third place on Arena.ai’s Code Arena WebDev lab leaderboard, where Anthropic and OpenAI currently lead and Google sits third. OpenAI’s GPT-6.1 Terra and GPT-6.1 Sol improved cost-efficiency and Terminal-Bench scores, while Moonshot’s Kimi K3.1 Pro and DeepSeek’s V4.1 Flash updates lifted their respective labs through better agentic frontend and full-stack performance at lower prices. Chinese labs such as Alibaba, Tencent, and Xiaomi continue closing gaps via Pareto-frontier gains on cost per task, creating a fluid ranking environment. With roughly a month until resolution, further capability jumps or efficiency breakthroughs from any contender could shift the third spot before November 30.
Rules
This market will resolve according to the third-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 November 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. 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 third 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".
