Description

This set of markets will resolve based on the Bitcoin price at a specific future timestamp, using a standardized benchmark for price verification. Each market has a different price threshold that must be met or exceeded for resolution.

Kalshi

All markets resolve based on the simple average of the sixty seconds of CF Benchmarks' Bitcoin Real-Time Index (BRTI) immediately before 5 PM EDT on September 20, 2026. For any market to resolve as 'Yes,' this average must exceed the specific threshold defined in that market's primary rule (e.g., $71,000.01 or above for the first market, $71,250.01 or above for the second, etc.). The official price is determined by collecting 60 BRTI prices during the final minute before expiration and averaging them. Note that cryptocurrency price data can vary across sources; the BRTI is the definitive reference for all resolution purposes, not consumer-facing platforms like Google or Coinbase.
