Polymarket odds that Anthropic will release the next Fable model by October 24 rose to 65%, up 13% over the past 24 hours. According to Odaily, the prediction-market tool said the contract will settle as Yes if Anthropic publicly launches Fable 5.2 or a later version before the deadline, and No otherwise.

The model name or identifier must include Fable and be at least version 5.2, including newer versions such as Fable 6. Public beta access or an open waitlist qualifies, while closed testing and private access do not. The settlement will mainly rely on Anthropic's official announcements and website information, along with consistent reports from credible media.
