Anthropic leads the WebDev Arena leaderboard with Claude Opus 5.5 (Max) at the top around 1810 Elo and multiple variants like Claude Sonnet 5.5 filling top spots, reflecting strong community preference in blind votes on front-end web app generation tasks. This stems from the September 2026 release of the Claude 5.5 family, which delivers frontier agentic coding performance—such as 66.4% on Terminal-Bench 4.0—at lower cost than prior Opus models while maintaining 1M context and excelling in multi-step reasoning and tool use for HTML/React workflows. OpenAI’s GPT-6 Astra and GPT-6.1 Sol trail closely in overall and full-stack categories but trail Anthropic’s edge in the primary front-end evaluations driving the market. With resolution weeks away and no major competing releases reported in early November, trader consensus aligns with the current Pareto frontier and vote volume exceeding 950,000.
Regler
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 November 30, 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".
