Description

The Transportation Security Administration (TSA) screens millions of passengers each week at airports across the United States. Tracking the average number of passengers screened over a specific week provides insight into travel trends and security operations during that period.

Kalshi

Each market resolves to Yes if the weekly average TSA airport screenings for the week ending October 11, 2026, exceed a specific threshold, ranging from above 1.8 million to above 2.8 million, as reported by the TSA. All contracts expire at the sooner of 9:00 AM following the data release for October 11, 2026, or one week after that date, with a fixed Last Trading Date and Time of 11:59 PM on October 11, 2026.

Frequently asked questions

On Kalshi, the dashboard for the TSA check-in volume market tracks the current odds of various outcomes related to the average number of people screened by the Transportation Security Administration between October 5th and 11th, 2026. You’ll find the implied probabilities, a price history chart showing how the market has traded, and the 24-hour trading volume, which is currently $1,384. The total volume traded to date is $11,811, indicating the level of interest in this particular forecast. This allows traders to assess sentiment and potential movements in the market.

Currently, the prevailing sentiment in this market suggests a different outlook than some traditional analyst forecasts. While many analysts predict continued growth in air travel, this market reflects a more nuanced view, factoring in potential disruptions or unexpected events. It's important to note that analyst forecasts are often based on models and assumptions that may not fully capture real-world complexities. This market, driven by the collective wisdom of traders, provides a dynamic and potentially more accurate assessment of the likely TSA check-in volume during the specified week. The market’s price action will reveal if it continues to diverge from, or converge with, those external predictions.

On Kalshi, this market is priced through a continuous double auction, meaning traders buy and sell contracts representing their belief about the outcome. The price of a contract reflects the probability of that outcome occurring, as perceived by the market participants. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate and new information becomes available, the prices adjust accordingly, creating a dynamic and real-time forecast. The current price indicates the market’s collective expectation for the average daily TSA check-in numbers during the specified period, offering a unique perspective compared to static forecasts.

This market resolves around Oct 12, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final average number of people screened by the TSA between October 5th and 11th, 2026, as reported by the TSA itself, will determine the winning outcome. The resolution will be based on publicly available data, ensuring transparency and objectivity. Traders will be able to see the final result and how it aligns with their predictions, providing valuable insights into the accuracy of the market’s forecast.

Several factors could significantly impact this market before it resolves. Major economic shifts, such as a recession or a surge in fuel prices, could affect travel demand and, consequently, TSA check-in numbers. Unexpected events like severe weather patterns, geopolitical instability, or public health concerns could also disrupt air travel and move the market. Additionally, changes in TSA policies or security protocols could influence screening times and volumes. Any news related to airline capacity, travel restrictions, or consumer confidence could also play a role in shaping the market’s price action.
