OpenAI’s recent launch of GPT-6 Astra (Max) has driven its commanding 79.3% market-implied odds, as the model quickly claimed the top spot on Code Arena’s WebDev leaderboard with a 1,797 score and a 35-point lead over Anthropic’s Claude Fable 5.1 (Max). This September 5 release demonstrated clear gains in agentic frontend coding, multi-step reasoning, and tool use on real-world web development tasks, shifting trader consensus toward OpenAI’s latest large language model. Anthropic holds a secondary 20% position on the strength of its prior frontier models, while Google, Moonshot, and other labs trail below 1% amid lower current benchmark placements. With end-of-September resolution approaching, any further verified leaderboard updates or capability demonstrations could still influence final outcomes.
