Resolves YES if Bitcoin undergoes a hard fork for any reason before 2027.

The chain with altered consensus must be generally accepted to be "Bitcoin" (see critera below). The old chain either becomes worthless or continues to exist under a different name.

If the fork is considered contentious, then this market will not resolve to YES until at least 95% of daily trading volume for the ticker BTC or XBT on exchanges that were established at least a year prior to the fork date are for the chain with altered consensus. If this fact is established within 90 days after the closing date of this market, but the hard fork occurred before 2027, the market will resolve to YES.
