Frequently asked questions

Currently, the volume is $2,965 and the total volume traded to date is $7,243. You can see how the implied probability of different check-in volume ranges changes over time, reflecting the collective predictions of traders. The dashboard provides a real-time view of market sentiment regarding passenger throughput at TSA checkpoints between September 28th and October 4th, 2026, offering insights into potential travel trends.

Comparing prediction market odds to analyst forecasts reveals how collective intelligence stacks up against expert opinion. While traditional forecasts rely on models and assumptions, this market aggregates the insights of numerous traders, potentially incorporating a wider range of information. If analysts predict a specific range of TSA check-ins, it's valuable to see whether this market assigns a higher or lower probability to that same outcome. Discrepancies can highlight areas where the market perceives information differently than experts, or where traders anticipate unforeseen events impacting travel volume.

On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts representing different possible ranges of average daily TSA check-in numbers between September 28th and October 4th, 2026. The price of each contract reflects the market's current expectation of that outcome occurring. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate, the prices adjust to reflect the collective wisdom of the crowd, creating a dynamic and informative prediction. The market's depth and volume indicate the level of confidence traders have in various scenarios.

This market resolves around Oct 5, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final average daily TSA checkpoint numbers for the period of September 28th to October 4th, 2026, as officially reported by the Transportation Security Administration (TSA), will determine the winning contract. The market will settle based on the official average, providing a clear and objective determination of the outcome. Traders will then receive payouts based on their positions and the final result.

Several signals or events could significantly move this market before Oct 5, 2026. Major economic indicators, such as changes in GDP growth or consumer confidence, could influence travel demand. Unexpected events like geopolitical instability, natural disasters, or public health concerns could also disrupt travel patterns. Furthermore, airline pricing strategies, major sporting events, or large conventions scheduled during that period could all impact TSA check-in volumes. Any news or data suggesting a shift in travel trends is likely to be reflected in the prices within this market.
