Will more than 2.5 million people travel through a TSA checkpoint on any day on or before December 31?

This is a market on whether more than 2.5 million people will travel through a TSA checkpoint on any single day on or after August 13, 2021 and on or before December 31, 2021. The resolution source for this market will be the daily checkpoint throughput as measured by the US Transportation Security Administration (TSA), https://www.tsa.gov/coronavirus/passenger-throughput. Should this URL change or move locations, the MIC will use its best judgement to pick a new URL on the tsa.gov domain. This market will resolve to “Yes” if the TSA reports a daily checkpoint throughput of more than 2.5 million for any day on or after August 13, 2021 and on or before December 31, 2021. This market will resolve to “No” otherwise. This market will resolve as soon as throughput data becomes available for the date of December 31, 2021 or on any date before that if the target is reached. If the target has not been reached and if data is not available for any of the days from August 13, 2021 to December 31, 2021 by January 7, 2022 the market will resolve to 50-50. Any revisions published to data for dates August 13, 2021 and onward prior to the release of data for December 31, 2021 will be considered. In the event of ambiguity in terms of the market outcome, the market will be resolved in good faith at the sole discretion of the Markets Integrity Committee (MIC).

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders at your target price. All positions are settled in USDC when the market resolves.

Resolution

Markets resolve through UMA's Optimistic Oracle. After the market closes, a proposer submits a resolution, followed by a 2-hour dispute window. If no dispute is raised, the resolution is accepted. Disputed markets go to UMA token holder vote.
