This market will resolve according to the company that owns the model that has the highest rank based on the arena.ai Code Arena | WebDev Leaderboard when the table under "Code Arena | WebDev" filtered for "Models" is checked on October 31, 2026, 12:00 PM ET. Results from the "Rank" column under the "Code Arena | WebDev" Leaderboard tab at https://arena.ai/leaderboard/code/webdev (Overall) filtered for "Models" 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. Models will be ordered primarily by their leaderboard rank at the market’s check time. 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 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 first 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".Intense competition among AI labs drives closely matched trader sentiment in this Code Arena WebDev market, where live crowdsourced voting on agentic frontend and fullstack coding tasks determines the leader by end-October. Recent expansions of the benchmark to include multi-file reasoning, tool use, databases, and fullstack workflows have elevated models from Anthropic, Google, OpenAI, and Chinese labs like Moonshot (Kimi), ByteDance, and DeepSeek, with frequent leaderboard shifts from new releases and high-volume votes exceeding 570,000. Key differentiators include demonstrated capabilities in complex web app generation, context handling up to 1M tokens, and cost-efficient performance, while uncertainty persists around upcoming model updates or capability jumps that could reorder rankings before resolution.
