Description

This event tracks the Transportation Security Administration's weekly average airport security check-ins during a specific week in 2026. It provides a way to assess public interest in air travel patterns by comparing actual check-in numbers against various thresholds.

Kalshi

All markets resolve based on whether the Transportation Security Administration reports a weekly average of airport screenings exceeding specified thresholds for the week ending September 20, 2026. Each market corresponds to a different threshold value, ranging from above 1.8 million to above 2.8 million screenings. Contracts expire at the earlier of 9:00 AM following data release for September 20, 2026, or one week after that date, with a consistent Last Trading Date and Time fixed at 11:59 PM on September 20, 2026. Resolution depends solely on the official TSA-reported average for the defined week, with all markets sharing identical expiration mechanics but differing only in their threshold requirements.

Frequently asked questions

On Kalshi, the dashboard for the TSA check-in market tracks the current price, price history, and 24-hour trading volume. Currently, volume is $2,056 and total volume traded to date is $10,111. The top outcome on Kalshi is whether more than 2750000 people will be screened by the TSA on average this week, though the chance percentage is not currently available. This allows traders to see how confidence in different outcomes is shifting in real-time, providing a dynamic view of expectations for airport security throughput.

Comparing prediction market odds to analyst forecasts for average weekly TSA check-ins reveals how collective intelligence stacks up against expert opinion. While analysts often provide point estimates or ranges, this market allows for a probabilistic view, reflecting the uncertainty surrounding future travel patterns. If analysts predict a specific number of travelers, we can see if the market price suggests a higher or lower probability of that outcome occurring. Discrepancies between the two can highlight areas where the market perceives risks or opportunities not fully captured by traditional analysis.

On Kalshi, this market is priced through a continuous double auction, where traders buy and sell contracts representing different outcomes. The price of a contract reflects the market’s implied probability of that outcome occurring. As more traders participate, the price converges towards a consensus view. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price movements are driven by supply and demand, influenced by news events, travel trends, and overall economic conditions. Traders are constantly adjusting their positions based on new information, leading to a dynamic and informative price discovery process.

This market resolves around Sep 21, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final average number of passengers screened by the TSA between September 14th and 20th, 2026, will be used to determine the winning outcome. This data will be sourced from official TSA reports and other publicly available sources. The resolution process ensures transparency and accuracy in determining the result of this market, providing a clear and verifiable outcome for all participants.

Several signals or events could significantly move this market. Major economic shifts, such as a recession or a surge in consumer spending, could impact travel demand. Unexpected events like severe weather patterns, geopolitical instability, or public health concerns could also disrupt air travel and affect TSA screening numbers. Additionally, changes in TSA staffing levels or security protocols could influence throughput. Any news related to airline capacity, travel restrictions, or major events attracting large crowds could also cause fluctuations in this market’s price.
