Kalshi
This event tracks the Transportation Security Administration's weekly average airport screenings during a specific week in 2026. It provides a way to assess potential trends in air travel demand by comparing actual screening numbers against various thresholds.
All markets resolve based on whether the Transportation Security Administration reports a weekly average of airport screenings above specified thresholds for the week ending September 27, 2026. Each market has a different threshold, ranging from 1.8 million to 2.8 million screenings. Contracts expire at the earlier of 9:00 AM following data release for that week or one week after September 27, 2026, with a consistent Last Trading Date and Time of 11:59 PM on September 27, 2026. Resolution depends solely on the official TSA-reported average for the specified period.
Comparing prediction market odds to analyst forecasts reveals how collective intelligence differs from expert opinions. For this market, it’s important to consider whether analysts’ predictions align with the current price action on Kalshi. If the market price suggests a significantly different outcome than what analysts are projecting, it could indicate that traders have access to information or insights that haven’t yet been incorporated into traditional forecasts. Discrepancies can arise from differing methodologies or a broader range of factors considered by market participants.
On Kalshi, this market is priced through a continuous double auction, where traders buy and sell contracts representing their beliefs about the average number of TSA check-ins during the specified week. The price of a contract reflects the probability of that outcome occurring. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders are incentivized to provide accurate predictions, as profitable trades are made when their forecasts align with the eventual outcome. The market dynamically adjusts as new information becomes available and traders update their expectations, creating a forward-looking assessment of the event.
This market resolves around Sep 28, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final average number of TSA security check-ins from September 21st to 27th, 2026, as reported by the Transportation Security Administration (TSA), will determine the outcome. The market will settle based on this official data, representing the actual average daily passenger volume during that period. Traders holding contracts corresponding to the closest predicted average will receive a payout.
Several signals or events could significantly move this market before it resolves. Major shifts in travel patterns, such as large-scale events, economic recessions, or changes in travel restrictions, would likely impact predicted check-in numbers. Unexpected news regarding airline capacity, airport staffing, or security protocols could also influence trading activity. Furthermore, any significant developments related to public health concerns or geopolitical events that affect travel demand could cause the price to fluctuate. Monitoring these factors will be key to understanding the dynamics of this market.
