These markets track the volume of passengers processed through U.S. Transportation Security Administration checkpoints on a specific future date. The outcomes depend on comparing the officially reported passenger count against various thresholds. Each market has a different threshold that determines whether it resolves as 'Yes' or 'No'.
All markets resolve based on the first published nationwide TSA passenger screening count for October 17, 2026, as reported on the TSA’s Passenger Volumes page. The exact count is used without rounding, and only the initial published figure counts—later corrections or revisions are disregarded. If the publication of the data is delayed, resolution is postponed until the data becomes available, subject to the contract’s expiration and any contingency rules. Each individual market has a unique threshold (ranging from 1,800,000 to 3,200,000 passengers); if the published count meets or exceeds that threshold, the market resolves to 'Yes,' otherwise it resolves to 'No.'
Currently, it's difficult to directly compare the predictions embedded in this market to traditional analyst forecasts, as those forecasts are not yet widely available for a date as far in the future as October 17, 2026. However, as the event approaches, it will be valuable to assess whether the collective wisdom of traders on Kalshi aligns with or diverges from expert predictions regarding travel volume. The question is whether the market will accurately anticipate changes in passenger numbers based on economic conditions, seasonal trends, and unforeseen events.
On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts that pay out $1 if the actual number of passengers screened falls within a specific range, and $0 otherwise. The price of a contract reflects the market’s probability assessment of that outcome occurring. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Prices fluctuate based on supply and demand, driven by new information and traders’ evolving beliefs about future passenger volumes. This dynamic pricing mechanism allows the market to aggregate information efficiently and provide a real-time forecast.
This market resolves around Oct 25, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final number of passengers screened by the TSA on October 17, 2026, as officially reported by the TSA itself, will determine the winning contracts. The resolution process will verify the official TSA data to ensure accuracy and transparency. Traders will then receive payouts based on whether their contracts correspond to the actual passenger screening count.
Several factors could significantly influence this market. Major economic shifts, such as a recession or a surge in economic growth, would likely impact travel demand and therefore passenger screening numbers. Geopolitical events, including international conflicts or travel restrictions, could also have a substantial effect. Unexpected events like a pandemic resurgence or major airline disruptions could also move the market. Finally, changes in TSA policies or security protocols could influence screening efficiency and overall passenger flow, impacting the predictions reflected in this market.
