This event tracks the Transportation Security Administration's weekly average airport screenings during a specific week in 2026. Participants can assess whether security checks will surpass various thresholds, reflecting expectations about travel demand and operational capacity.
All markets resolve based on whether the weekly average TSA airport screenings for the week ending October 25, 2026, exceed specified thresholds, ranging from 1.8 million to 2.8 million. Each market has a unique threshold, and if the actual average surpasses that threshold, the market resolves to Yes; otherwise, it resolves to No. Contracts expire at the earlier of 9:00 AM following the data release for the week of October 25, 2026, or one week after October 25, 2026. The last trading date and time for all markets is consistently 11:59 PM on October 25, 2026, ensuring all participants have a defined window to trade based on anticipated screening volumes before the official data is released.
Comparing prediction market odds to analyst forecasts reveals how collective intelligence stacks up against expert opinions. For this market, the question is whether more than 2250000 people will be screened by the TSA on average during the specified week. While traditional forecasts rely on models and assumptions, this market aggregates the insights of numerous traders, potentially offering a more dynamic and accurate prediction. Discrepancies between the market price and analyst expectations can highlight areas of disagreement or overlooked factors influencing travel volume, such as economic conditions or major events.
On Kalshi, this market is priced through a continuous double auction, where traders buy and sell contracts representing their beliefs about the future outcome. The price of a contract reflects the probability of that outcome occurring, as determined by supply and demand. Traders who believe the average TSA check-ins will exceed a certain level will buy contracts, driving up the price, while those who believe it will fall below will sell. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market’s price movements are a real-time reflection of evolving expectations, influenced by news, data releases, and overall market sentiment.
This market resolves around Oct 26, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final average number of people screened by the TSA from October 19 to 25, 2026, as reported by the TSA itself, will determine the outcome. This data will be sourced from official TSA publications and will be used to determine whether the market resolves in favor of the 'yes' or 'no' outcome—that is, whether more than 2250000 people were screened on average during that week.
Several signals and events could significantly move this market before its resolution. Major economic indicators, such as changes in GDP growth or consumer confidence, could influence travel demand and therefore TSA check-in numbers. Unexpected events like natural disasters, geopolitical instability, or significant public health concerns could also disrupt travel patterns. Furthermore, policy changes related to travel restrictions or security protocols could have a direct impact. Any news regarding airline capacity, fuel prices, or major sporting/entertainment events scheduled during that week could also shift trader sentiment and affect the price of this market.
