This set of markets will determine whether Bitcoin's price exceeds various thresholds at a specific future moment. The outcomes are based on a standardized price index measured at a precise time, offering a clear benchmark for evaluating Bitcoin's performance against different price points.
All markets share a unified resolution mechanism centered 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 has a distinct price threshold, specified as "$X or above," and resolves to "Yes" if the calculated average exceeds the respective threshold by at least 0.01. The official price is derived from averaging 60 BRTI readings captured in the final minute before expiration, ensuring consistency across all markets. Secondary rules emphasize that while public sources like Google or Coinbase may offer reference points, the BRTI serves as the definitive data source for resolution.
