How research works41,800,260 people tuned in to watch the inauguration of Ronald Reagan on Tuesday, Jan. 20, 1981, the most viewed in history (see: https://www.nielsen.com/insights/2013/presidential-inauguration-draws-20-6-million-viewers/). This market will resolve to "Yes" if Trump's inauguration has more than 41,800,260 viewers. Otherwise, this market will resolve to "No". The resolution source will be information from Nielsen, specifically their Persons 2+ statistic. If Nielsen does not provide viewership information for Trump's inauguration by January 31, 2025, 11:59 PM ET, another credible source may be chosen.
