Description

This event tracks Bitcoin's price performance at a specific future timestamp, using a standardized index to determine the outcome. The resolution depends on whether the price falls within predefined ranges at the exact moment of evaluation.

Kalshi

The event resolves based on the simple average of the sixty seconds of CF Benchmarks' Bitcoin Real-Time Index (BRTI) immediately before 5 PM EDT on September 17, 2026. Each numbered market corresponds to a specific price range, and the market resolves to 'Yes' if the calculated average falls within that range. The official price is derived from averaging 60 BRTI prices collected in the final minute before expiration. All markets share identical secondary rules emphasizing that CF Benchmarks' BRTI is the definitive source, distinguishing it from other price feeds, and detailing the methodology for determining the final value from the collected data points.
