I'll measure the time from the first touch of their hands to the moment they release. If they shake hands multiple times, only the duration of the first handshake will count. Whether they touch each other's shoulders or their bodies do something else doesn't matter.

If the timing is difficult for me to judge precisely and falls between two options, I will resolve 50% chance to each option. [I will not bet on this market.]

This market will be considered N/A if the debate doedn't take place in June or if they do not shake hands during CNN's official live coverage. I will follow @Joshua 's market and definition of a handshake, and will resolve this question as N/A if @Joshua's market resolves to NO.

This market is intended to be about the scheduled CNN debate on June 27th, but would also include if that debate were rescheduled or cancelled or cancelled and replaced with another debate, so long as it happens in June 2024.

This market will be scheduled to close just before the debate, and will resolve the day after.
