Will more than 2.5 million people travel through a TSA checkpoint on any day on or before May 1, 2022?

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 February 19, 2022, and on or before May 1, 2022. 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 a new URL on the tsa.gov domain will remain valid to resolve this market. This market will resolve to “Yes” if the TSA reports a daily checkpoint throughput of more than 2,500,000 for any day on or after February 19, 2022, and on or before May 1, 2022. This market will resolve to “No” otherwise. This market will resolve as soon as throughput data becomes available for the date of May 1, 2022, 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 February 19, 2022, to May 1, 2022, by May 10, 2022, the market will resolve to 50-50. Any revisions published to data for dates February 19, 2022 and onward prior to the release of data for May 1, 2022, will be considered.

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.
