If the price of BTC after issuance and through 11:59 PM ET on Aug 31, 2026 is ever below $60000.00, then the market resolves to Yes. At each minute throughout the market duration, a settlement value is calculated using every minute-by-minute CF BRTI price for BTC. For each of these individual minute-by-minute checks, the top 20% and bottom 20% of the cumulative dataset are removed before calculating the average of the remaining values. If the trimmed mean associated with any single minute during the period is below the threshold, the market resolves to Yes. This methodology reduces the impact of extreme price spikes or drops. The measurement period runs from when the market is issued until the specified end time. If CF Benchmarks data is unavailable or incomplete at the expiration time, affected strikes resolve to No. For cryptocurrencies with multiple versions, the Exchange will specify which version or ticker is being tracked.

    Bitcoin above $42.5K through August stays near full pricing Kalshi ladder
    • The prediction market ladder shows only 1% probability that BTC trimmed mean falls below $42,500 by August 31, a near-certain floor at current levels.
    • The $115 million Coldcard hack and 28,000 BTC returning to exchanges are bearish supply-side signals, yet the ladder's floor pricing is not reflecting acute downside risk.
    • The upper-bound ladder (CM-EVT-91N8R2ZK22) shows only 28% probability BTC trades above $67,500 by month-end, capping the range implied by the two ladders at roughly $42,500-$67,500.
    • Bitcoin spot price cited in Story 31 at $64,127 sits near the upper end of that range, consistent with the 28% probability of a breakout above $67,500.
