If any of the listed are confirmed to be Satoshi Nakamoto by the close date, their market will resolve YES. Otherwise they will resolve NO. There can be more than 1 resolved YES if Satoshi is proven to be multiple people. This will resolve based on either reporting from a reputable source (major news organization) and preferably the Satoshi Nakamoto Wikipedia page would also be updated.

If I'm missing anyone, feel free to comment and I will add them.
