This event tracks Bitcoin's price performance at a specific future moment, using a standardized benchmark to determine the outcome. It tests whether the cryptocurrency's value falls within any of several defined ranges at the exact time specified.
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 July 29, 2026. Each market corresponds to a specific price range, and the official price is determined by averaging 60 BRTI readings collected in the final minute before expiration. Only one market will resolve as 'Yes' — the one whose range contains the calculated average price — while all others resolve as 'No.' The secondary rules clarify that CF Benchmarks' BRTI is the definitive source, distinguishing it from other price feeds, and emphasize the methodology for determining the final value from the collected data points.
