Description

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

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 28, 2026. Each market corresponds to a specific price range, with outcomes determined by whether the calculated average falls within that range. The official price is derived from averaging 60 BRTI readings collected during the final minute before expiration. Participants should note that prices displayed on consumer platforms like Google or Coinbase may differ from the official CF Benchmarks source used for resolution.
