BTC price on Sep 22, 2026 at 5pm EDT?

All markets share a common resolution methodology centered on the Bitcoin Real-Time Index (BRTI) published by CF Benchmarks. For each market, the resolution hinges on whether the simple average of the sixty seconds of BRTI price data immediately preceding 5 PM EDT on September 22, 2026, exceeds a specified threshold. The thresholds vary incrementally across markets, each defining a unique price boundary. At the expiration moment, exactly 60 price readings from the BRTI are gathered within the final minute before 5 PM EDT; the average of these readings constitutes the official price used to evaluate all thresholds. This approach ensures consistency across all markets by relying solely on the CF Benchmarks index, distinguishing it from consumer-facing sources like Google or Coinbase, which may report differing values due to varying data aggregation methodologies or update frequencies. The use of a tightly bounded, high-frequency sample window minimizes volatility effects and provides a precise, reproducible benchmark for settlement.
