Anthropic’s recent Claude Fable 5.1 and Opus 5 releases have driven its 63.5% market-implied probability by topping composite leaderboards on Artificial Analysis, LMArena Elo, and BenchAlign for intelligence, coding, reasoning, and agentic tasks as of early September 2026. These models outperform OpenAI’s GPT-6 Astra and GPT-5.6 Sol on key evaluations while delivering strong price-performance trade-offs, reinforcing trader consensus around Anthropic’s edge in frontier capabilities. OpenAI’s parallel Astra launch narrowed some gaps in specific workflows but has not displaced Anthropic’s lead. With only months remaining until year-end, the market reflects expectations that Anthropic’s iteration pace and benchmark momentum will hold against faster-following rivals like Google and xAI.

Results from the "Rank" section on the Leaderboard tab of https://lmarena.ai/leaderboard/text with the style control off will be used to resolve this market.
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 their Arena score, including any underlying, unrounded, granular values reflected in the data below the leaderboard. If a tie remains, alphabetical order of company names as listed in this market group will be used as a final tiebreaker (e.g., if the two models are tied by exact arena score, “Google” would be ranked ahead of “xAI”). This market will resolve based on the company that occupies first place under this ranking system.
