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”).
