Settles YES when
Each contract resolves on the simple average of the 60 one-second prints of CF Benchmarks' Bitcoin Real-Time Index (BRTI) in the minute before the top of the hour: YES if that average is above, below, or inside the contract's price range (depending on the variant). A new event settles every hour, around the clock, and the contract text names the hour.
4 resolution traps in the KXBTC rules
The wording that changes how or when the contract settles β which data source and which print, the exact metric, rounding, date boundaries, void conditions.
Bitcoin rangeEach contract resolves on the simple average of the 60 one-second prints of CF Benchmarks' Bitcoin Real-Time Index (BRTI) in the minute before the top of the hour: YES if that average is above, below, or inside the contract's price range (depending on the variant). A new event settles every hour, around the clock, and the contract text names the hour.4 traps
- BRTI 60-second simple average, not spot price β Resolution uses the arithmetic mean of exactly 60 one-second BRTI values ending at the top of the settlement hour β a single instantaneous Bitcoin price at that moment is irrelevant and could differ materially from the average.
- Strict boundary comparisons β endpoints matter β Variant 1 requires strictly above the threshold (so hitting it exactly resolves NO), Variant 2 requires strictly below its threshold (same risk), and Variant 3 uses an inclusive range up to x.99 β a trader must check whether the averaged value clears the boundary strictly or lands exactly on it.
- Every hour is its own event β check the hour and the timezone β Events settle hourly and the contract text names the hour in Eastern time; any clock or feed displaying UTC or another timezone could cause a trader to misidentify the relevant 60-second window.
- CF Benchmarks BRTI is the sole data source β Only CF Benchmarks' official BRTI publication governs resolution β prices from other exchanges, aggregators, or index providers (e.g., CME CF Bitcoin Reference Rate) are irrelevant even if they show different values at the same moment.

Frequently Asked Questions
How does Kalshi settle Bitcoin range markets?
Each contract resolves on the simple average of the 60 one-second prints of CF Benchmarks' Bitcoin Real-Time Index (BRTI) in the minute before the top of the hour: YES if that average is above, below, or inside the contract's price range (depending on the variant). A new event settles every hour, around the clock, and the contract text names the hour. That criterion is the whole contract β the headline question is a summary of it, not the rule itself.
What can go wrong when a Bitcoin range contract resolves?
We flag 4 traps in these rules. The first: BRTI 60-second simple average, not spot price β Resolution uses the arithmetic mean of exactly 60 one-second BRTI values ending at the top of the settlement hour β a single instantaneous Bitcoin price at that moment is irrelevant and could differ materially from the average.
What does the KXBTC ticker mean?
KXBTC is Kalshi's series ticker for Bitcoin range. Individual contracts append the event and the strike β 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.
This is our reading of Kalshiβs published resolution rules, not a substitute for them β read the contract before taking a position. Prediction markets carry risk; contracts can settle at $0. Informational only, not financial advice.
