Bitcoin price on Sep 25, 2026?

How this settles

Resolves YES if the simple 60-second average of CF Benchmarks' Bitcoin Real-Time Index (BRTI) immediately before the settlement window (either 8 AM or 5 PM EDT on the settlement date) is strictly above the threshold.

• Strict 'above' — hitting threshold exactly resolves NO — The rules require the average to be above X.99 (e.g. above 77699.99 / 86249.99), so a BRTI average landing exactly on the threshold value fails the condition and resolves NO.
• CF Benchmarks BRTI is the sole data source — Only CF Benchmarks' BRTI is used — no other Bitcoin price feed or exchange price counts, so discrepancies between BRTI and other indices are irrelevant to settlement.
• 60-second average, not a spot print — Settlement uses the simple average of the 60 individual one-second BRTI values immediately before the cut-off, not any single spot price, so a momentary spike or dip through the threshold does not determine the outcome.
• Two separate variants with different times and thresholds — The 8 AM EDT variant and the 5 PM EDT variant carry different thresholds; traders must confirm which variant their specific contract references, as holding the wrong one exposes them to a completely different strike and settlement window.

These are the rules for the whole series — every contract in it settles the same way. Full KXBTCD settlement rules →
