The outcome is decided by the US dollar price of Bitcoin in the CF Benchmarks Bitcoin Real-Time Index, published by CF Benchmarks. For each minute, all index values in that minute are collected, the highest 20% and lowest 20% are removed, and the remaining 60% are averaged to give a trimmed-mean price. A qualifying crossing happens when that trimmed-mean price moves from one side of the value specified in the market question to the other: for exceed, from at or below it to strictly above it, and for fall below, from at or above it to strictly below it. Where the market question says again, only the first qualifying crossing after listing counts. The outcome is Yes on the first qualifying crossing before January 2028, and it can resolve early at that point; otherwise it is No, determined at 11:59 PM CT on the last day before January 2028 begins, and if the index data is delayed, resolution waits until it is published.
