This event tracks Bitcoin's price performance at a specific future moment, using a trusted benchmark index to determine the outcome. The resolution depends on where the price falls within predefined ranges at the exact closing time.
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 26, 2026. Each market corresponds to a specific price range, with outcomes determined by whether the average falls within that range. For all markets, the official price is derived from collecting 60 RTI prices during the final minute before expiration, then calculating their average. While public sources like Google or Coinbase may offer reference points, they are not authoritative—the CF Benchmarks BRTI is the sole determinant of resolution for every market in this set.
