About this market

Final prediction market prices for "Number of TSA passengers March 23 - March 29?". 18.5-19m last traded at 0.1%. Next is 19-19.5m at 0.1%. $21K has traded across 2 outcomes on Polymarket. The market closed on Mar 29, 2026.

This market will resolve to the total number of TSA passengers reported between March 23, 2026 and March 29, 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 March 23, 2026 to March 29, 2026 by April 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.

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.
