How this settles
Resolves YES if the simple 60-second average of CF Benchmarks' Bitcoin Real-Time Index (BRTI) immediately before the contract's designated settlement time (8 AM or 5 PM EDT on the settlement date) is strictly above the threshold.
- BRTI 60-second average, not spot price — Settlement uses the simple average of the 60 individual one-second BRTI prints in the minute before the cut-off, so a brief spike or dip to the threshold level in spot price does not determine resolution — the averaged value does.
- Strictly above threshold, not equal — The rule resolves YES only if the average is above the threshold (e.g. above 64,299.99 or 72,749.99), meaning a final averaged value exactly equal to the threshold resolves NO.
- CF Benchmarks BRTI is the sole data source — Other Bitcoin price feeds (Coinbase, Binance, CME reference rate, etc.) are irrelevant — only CF Benchmarks' official BRTI publication governs, so discrepancies between venues don't matter unless BRTI itself reflects them.
- Two separate variants with different times and thresholds — The 8 AM EDT and 5 PM EDT variants carry different strike thresholds; a trader must confirm which variant their contract references, as holding the wrong one means exposure to a completely different settlement window and price level.
These are the rules for the whole series — every contract in it settles the same way. Full KXBTCD settlement rules →
