Polymarket’s probability that GPT Astra 6.1 or higher will be released before November 15 rose to 44%, up 12% over 24 hours; the probability of a release before November 30 climbed to 65%, up 4%. According to Odaily, the markets will resolve to “Yes” if OpenAI makes a GPT model publicly available by the specified date with version 6.1 or higher and “Astra” in its name or model identifier. Closed tests and placeholder names appearing only on OpenAI’s website do not qualify, and settlement will be based primarily on official OpenAI information.
