Description

This market will resolve to the total number of TSA passengers reported between May 11, 2026 and May 17, 2026 (inclusive). The total number of TSA passengers will be calculated by summing all of the TSA daily checkpoint throughputs reported for this date range (e.g. if there were a daily TSA checkpoint throughput of 2 million reported on December 1 and a daily TSA checkpoint throughput of 3 million reported on December 2, the total number of TSA passengers for December 1-2 would be 5 million). If the reported total number of TSA passengers falls exactly between two brackets, then this market will resolve to the higher range bracket. This market will resolve as soon as throughput data becomes available for all dates within the listed range. Any revisions published to data for dates December 8, 2025 and onward prior to the release of data for all dates within the listed range will be considered. If data is not available for any of the dates from May 11, 2026 to May 17, 2026 by June 30, 2026, this market will resolve to "Other". The resolution source for this market will be the daily checkpoint throughputs as measured by the US Transportation Security Administration (TSA), https://www.tsa.gov/travel/passenger-volumes. Should this URL change or move locations, a new URL on the tsa.gov domain will remain valid to resolve this market.
