Polymarket Puts Fable 5.2 or Later Release Odds at 70% by Oct. 17

The probability of Anthropic making Fable 5.2 or a later model publicly available by Oct. 17 rose to 70%, a 36% increase over 24 hours, under the market’s settlement rules.

The deadline is measured in Eastern time. To qualify, a model’s name or identifier must include “Fable” and its version must be 5.2 or higher, including later versions such as Fable 6.

A public beta or a waitlist open to the public counts as public availability. Closed testing and private access do not qualify. Settlement is based primarily on Anthropic’s official announcements and website, with credible media coverage as supporting evidence.
