This event tracks Bitcoin's price performance at a specific future timestamp, using a standardized index to determine the outcome. The resolution hinges on whether the price falls within predefined ranges at the exact moment of evaluation.
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 10, 2026. Each market corresponds to a specific price range, and the official price is determined by averaging 60 BRTI prices collected in the final minute before expiration. The secondary rules emphasize that CF Benchmarks' BRTI is the definitive source, distinguishing it from other price feeds, and clarify the methodology for calculating the final average value used to resolve all markets.
