Description

This event tracks Bitcoin's price performance at a specific future moment, using a standardized benchmark index to determine the outcome. The resolution depends on where the price falls within predefined ranges at the exact closing time, reflecting potential market trends without referencing specific counts of outcomes.

Kalshi

The event resolves 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. Each market corresponds to a specific price range, and the official price is determined by averaging the BRTI prices collected in the final minute before expiration. The average must fall within the defined range for that market to resolve as 'Yes'; otherwise, it resolves as 'No.' All markets share the same data source and methodology, ensuring consistency across outcomes. The secondary rules emphasize that while public sources like Google or Coinbase may offer guidance, the resolution strictly follows the CF Benchmarks' BRTI data.
