The wording that changes how or when the contract settles — which data source and which print, the exact metric, rounding, date boundaries, void conditions.
Bitcoin rangeThe contract resolves YES if the simple average of the 60 one-second BRTI prints in the minute ending at the settlement time falls strictly within the named price range (inclusive of both endpoints) on the named settlement date.4 traps
- Specific data source: CF Benchmarks BRTI only — Settlement uses CF Benchmarks' Bitcoin Real-Time Index exclusively — no other Bitcoin price feed (spot exchange prices, CME fixes, etc.) is a valid substitute, even if they diverge.
- 60-second simple average, not spot price — The resolving price is the arithmetic mean of 60 individual second-level BRTI prints before the settlement time, so a single spot price at the settlement moment is irrelevant and can differ materially from the average.
- Upper bound is 64249.99 — hitting exactly 64250 resolves NO — The range is stated as 64000–64249.99, so a averaged price of 64250.00 or higher falls outside the range and resolves NO, making the precise decimal ceiling critical.
- Inclusive lower bound: exactly at threshold resolves YES — The lower bound of the range is inclusive (64000), so a trader must know the comparison is ≥ the floor and ≤ the ceiling to correctly assess edge-case scenarios near either boundary.

What does the KXBTC ticker mean?
KXBTC is Kalshi's series ticker for Bitcoin range. Individual contracts append the event and the strike — so one series carries many contracts, all settling under the same rule. This page covers the rule; the board above lists the contracts open right now.
Do you have a record trading Bitcoin range?
Not yet. We track KXBTC settlement rules, but no position on this series has been graded, so there is no record to show. We would rather say that than show a zeroed scorecard.
