Description

This event tracks Bitcoin's price performance at a specific future moment, using a standardized benchmark to determine the outcome. The resolution depends on whether the price falls within predefined ranges at the exact closing time, providing a clear, time-bound test of market expectations.

Kalshi

All markets resolve based on the simple average of the sixty seconds of CF Benchmarks' Bitcoin Real-Time Index (BRTI) immediately before 5 PM EDT on September 20, 2026. Each market corresponds to a specific price range, and the official price is determined by averaging the BRTI values collected in the final minute before expiration. The average must fall within the stated range for that market to resolve as 'Yes'; if it falls outside all defined ranges, all markets resolve as 'No'. The use of CF Benchmarks' BRTI ensures consistency, as general price sources like Google or Coinbase may differ from the official data used for resolution.
