This market will resolve according to the length of the longest filmed handshake between Donald Trump and Zohran Mamdani on Friday, November 21, 2025, ET. Any handshake recorded during that date ET will qualify.

If a handshake is photographed but not captured on video, this market will resolve to "Photographed only".

If no handshake occurs on November 21, 2025, ET this market will resolve to “No Handshake.”

Duration will be measured from the exact moment their hands make initial physical contact until the exact moment either breaks contact.

If the measured duration falls exactly on the boundary between two duration brackets, this market will resolve to the higher bracket.

Qualifying Requirements:
The handshake must be voluntary, intentional, and in person.
Direct hand-to-hand contact is required (gloves or mittens permitted).
The handshake must be clearly visible on video from start to finish.

Non-qualifying examples:
Fist bumps, hugs, waves, or other non-handshake greetings.
Any handshake too unclear to measure.

The primary resolution source will be publicly available video footage or photographs from credible media outlets or official recordings.
