This is a market on whether more than 2.4 million people will travel through a TSA checkpoint on any single day between April 26, 2022 and May 24, 2022 (inclusive). 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 2,400,000 for any day between April 26, 2022 and May 24, 2022 (inclusive). This market will resolve to “No” otherwise. This market will resolve as soon as throughput data becomes available for the date of May 24, 2022, or on any date before that if the target number is reached. If the target number has not been reached and if data is not available for any of the days from April 26, 2022, to May 24, 2022, by June 3, 2022, the market will resolve to 50-50. Any revisions published to data for dates April 26, 2022, and onward prior to the release of data for May 24, 2022, will be considered.
Questions
What does the consensus price mean?
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
How is the payout worked out?
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Why do the venues show different prices?
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Is a price gap an arbitrage?
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
How fresh are these prices?
Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
