Description

The Transportation Security Administration (TSA) conducts security screenings at airports across the United States. The average number of passengers screened each day can fluctuate due to travel patterns, holidays, and other factors, making predictions about weekly totals challenging and subject to change based on real-time conditions.

Kalshi

Each market resolves to Yes if the weekly average TSA airport screenings for the week ending August 30, 2026, exceed a specific threshold, ranging from above 1.8 million to above 2.8 million, as reported by the TSA. All markets share identical secondary rules: contracts expire at the sooner of 9:00 AM following data release for August 30, 2026, or one week after August 30, 2026, with a fixed Last Trading Date and Time of 11:59 PM on August 30, 2026.

Frequently asked questions

On Kalshi, the dashboard for the TSA travel volume market tracks real-time odds and price history for whether average weekly Transportation Security Administration passenger screenings will exceed two million during the specified period. It also shows 24-hour volume of $898 to reflect trader interest. This focused view lets participants monitor how market expectations shift ahead of the Aug 31, 2026 settlement date.

On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, traders actively set the price through buying and selling contracts that represent the two possible outcomes. The current implied probability reflects the collective assessment of participants about future TSA screening numbers. As new data emerges — such as weekly passenger surveys or airline capacity reports — the price can shift rapidly, adjusting the market’s expectation of exceeding two million screenings.

This market resolves around Aug 31, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the average number of passengers screened by the TSA from August 24 to August 30, 2026, will be calculated and compared against the two-million threshold. The result is settled based on officially released TSA statistics and widely accepted public datasets.

Several signals could influence this market before Aug 31, 2026. Notable movements may include published TSA passenger statistics from prior weeks, major disruptions or improvements in air travel (such as weather events, labor actions, or policy changes), and revisions to airline flight schedules. Economic indicators affecting disposable income and travel demand — like fuel price shifts or federal travel incentives — may also cause traders to adjust their positions, impacting the market’s implied probability.
