OpenAI’s GPT-6 Astra, released September 3, 2026, quickly claimed the top spot on the Code Arena WebDev leaderboard with scores near 1,800 points, outpacing Anthropic’s Claude Fable 5.1 by roughly 35 points on crowdsourced Elo-style rankings of agentic frontend tasks. This rapid ascent after launch underpins the 72% market-implied probability for OpenAI, reflecting trader confidence in its sustained edge through October. Anthropic holds 22% odds on the strength of its recent Fable 5.1 and Opus 5 releases, while lower-priced challengers like Alibaba’s Qwen series, Meta’s Muse Spark, and Z.ai’s GLM models trail but demonstrate competitive Pareto efficiency. Key catalysts ahead include any October model updates or leaderboard shifts before resolution.

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.
