Anthropic's Claude Fable 5.1 and related Opus variants drive the 87.9% implied probability through consistently high coding scores on LiveBench's contamination-resistant tasks, including code generation and completion, where recent evaluations place them ahead of competitors. OpenAI models such as o3-mini and GPT-5 series trail at 9.7% amid slightly lower category-specific results, while other providers remain near zero due to limited demonstrated parity. With the September 30 resolution imminent and LiveBench refreshing questions periodically, traders are weighting Anthropic's edge in verified coding benchmarks and recent model iterations over potential last-minute shifts. This reflects aggregated real-money sentiment on current frontier large language model capabilities rather than guarantees.

Results from the “Coding” column of the leaderboard at https://livebench.ai/#/?cats=Coding, with the latest available LiveBench release selected and the category set to “Coding,” will be used to resolve this market.
Models will be ranked according to the specified score, with higher scores ranked ahead of lower scores. If two or more models have exactly the same score as displayed on the leaderboard, the model with the lower listed "cost per successful task" will be ranked ahead. 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., if the two models are tied by exact score and cost per successful task, “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 LiveBench 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. If it becomes permanently unavailable, this market will resolve to “Other.”
