Polymarket odds that Anthropic's next Claude Opus model will be released before September 27 rose to 90%, up 13% over the past 24 hours. According to ChainCatcher, the probability of a release before September 30 increased to 94%, up 7% in 24 hours.
Under the market's settlement rules, the prediction resolves to Yes if Anthropic makes the next Claude Opus model publicly available by the specified date in U.S. Eastern Time. The model must be explicitly named Opus by Anthropic and opened to public access, including open testing or a public waitlist rollout; closed testing or private access does not qualify.
