PolymarketRules
This market will resolve to "Yes" if the standard output token price of Anthropic's latest Claude Opus model is equal to or beyond (above for ↑ High Prices, below for ↓ Low Prices) the price specified in the title, in USD per million tokens, at any point between market creation and December 31, 2026, 11:59 PM ET.
- Otherwise, this market will resolve to "No".
- Anthropic's latest Claude Opus model means the model with the highest version number among models by Anthropic explicitly named Opus, such as Claude Opus 5 or Claude Opus 5.5, that have a standard output token price listed on Anthropic's official API pricing page.
- If more than one such model shares the highest version number, the most recently released of them applies.
- Only models that are publicly accessible, including via open beta or open rolling waitlist signups, will be considered; models available only through a closed beta or any form of private or limited access will not qualify.
- The relevant price is the “Base tokens” output price on Anthropic’s official API pricing page for default global inference, at the rate applicable to requests that do not trigger a long-context surcharge.
