Anthropic's Claude models, including Opus 5 and Fable 5.1 variants, have driven the 81.5% implied probability for second-best Code Arena WebDev AI lab by consistently leading or near-leading recent coding benchmarks such as SWE-bench Pro, CursorBench, BigCodeBench, and SWE-Rebench as of September 18, 2026. These results reflect strong agentic performance on multi-file, iterative web development tasks that align closely with Code Arena's evaluation of fullstack capabilities like database integration and real-time deployment. OpenAI trails at 16.7% amid competitive but lower scores on the same leaderboards, while other labs remain under 3% due to limited recent gains in verified software engineering metrics. With resolution approaching in under two weeks, any new model releases or benchmark updates could still influence final trader consensus.

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 September 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.
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.
