Description

This set of markets will determine whether Bitcoin's price reaches various specific thresholds by a fixed date and time. Each threshold represents a different price level that Bitcoin must exceed for the corresponding market to settle as 'Yes'. The outcomes are based on a standardized, averaged price index measured at a precise moment.

Kalshi

All markets share a common resolution mechanism based on the simple average of the sixty seconds of CF Benchmarks' Bitcoin Real-Time Index (BRTI) immediately before 5 PM EDT on October 18, 2026. For any given market, if this average exceeds the specified threshold (e.g., $71,499.99, $72,000.00, etc.), the market resolves to 'Yes'; otherwise, it resolves to 'No'. The BRTI is the sole source for price determination, and the official value is derived from averaging 60 RTI prices collected in the final minute before expiration. All secondary rules consistently emphasize that while public sources like Google or Coinbase may offer reference points, they are not authoritative for these markets—only the CF Benchmarks BRTI average is binding for resolution.
