This event tracks Bitcoin's price performance at a specific future timestamp, dividing possible outcomes into narrow numerical ranges for analysis. The resolution depends solely on the cryptocurrency's value at precisely 5 PM EDT on September 13, 2026, measured by a designated benchmark index.
All markets resolve based on the simple average of the sixty seconds of CF Benchmarks' Bitcoin Real-Time Index (BRTI) immediately preceding 5 PM EDT on September 13, 2026. Each market corresponds to a specific price range, with outcomes determined by where this average falls: below $67,250, between $67,250 and $86,749.99, or above $86,749.99. The official price is calculated from 60 BRTI readings collected during the final minute before expiration, emphasizing that CF Benchmarks' index—not public exchanges like Google or Coinbase—defines the resolving value. All secondary notes consistently reinforce this data source and methodology across every market.
