BTC price on Aug 27, 2026 at 5pm EDT?

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 August 27, 2026. For any given market to resolve to 'Yes,' this average must exceed the specific threshold defined in that market's primary rule at the exact expiration time. Each threshold is sequentially higher, creating a tiered structure where exceeding any lower threshold automatically satisfies all markets with lower or equal thresholds. The official price is determined by averaging 60 RTI price readings collected during the final minute before expiration, ensuring precision and consistency across all markets. Secondary rules uniformly clarify that while public sources like Google or Coinbase may offer reference points, the definitive price comes exclusively from CF Benchmarks' BRTI, eliminating discrepancies from using alternate data providers.
