Description

This set of markets focuses on predicting the volume of travelers passing through Transportation Security Administration (TSA) checkpoints during a specific week. Each market corresponds to a different threshold of average daily screenings, allowing participants to assess varying levels of traffic intensity. The outcomes are determined by official TSA data released after the week in question.

Kalshi

All markets resolve based on the weekly average number of TSA airport screenings reported for the week ending October 18, 2026. Each market has a specific threshold; if the reported average exceeds the threshold, that market resolves to 'Yes.' Contracts for all markets expire at the earlier of 9:00 AM following the data release for October 18, 2026, or one week after October 18, 2026. The last trading date and time for all markets is consistently 11:59 PM on October 18, 2026. The resolution hinges solely on the TSA's official weekly average screening count for the specified period.

Frequently asked questions

On Kalshi, the dashboard for the TSA check-in market tracks the current odds, price history, and 24-hour trading volume. Currently, the total volume for this market is $12,678, with $5,784 traded in the last 24 hours. Traders on Kalshi are expressing their beliefs about the average number of TSA check-ins between October 12th and 18th, 2026, through these prices. The dashboard provides a visual representation of how these probabilities have shifted over time, allowing you to analyze market sentiment and potential trading opportunities related to this specific event.

Comparing prediction market odds to analyst forecasts reveals how collective intelligence stacks up against expert opinion. For this market, it’s important to consider that analysts’ predictions about future TSA check-in numbers are often based on economic models and historical trends. However, this market incorporates a wider range of information and real-time adjustments based on evolving circumstances. Discrepancies between the two could indicate that traders perceive factors not fully accounted for in traditional forecasts, or simply reflect differing levels of confidence in the underlying assumptions regarding travel volume and security procedures.

On Kalshi, this market is priced through a continuous double auction, where traders buy and sell contracts representing different possible outcomes. 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. Prices adjust dynamically based on supply and demand; increased buying pressure drives prices up, indicating higher perceived probability, while increased selling pressure drives prices down. This creates a real-time assessment of expectations for the average TSA check-ins during the specified period, offering a forward-looking indicator beyond simple polling data.

This market resolves around Oct 19, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution will be based on the official average daily passenger throughput numbers reported by the Transportation Security Administration (TSA) for the period of October 12th to October 18th, 2026. These figures will be sourced from publicly available TSA data and verified against credible public sources to ensure accuracy. The market will settle to the closest whole number representing the average daily check-ins during that timeframe.

Several signals or events could significantly move this market before its resolution. Major economic shifts, such as a recession or substantial changes in fuel prices, could impact travel demand and therefore TSA check-in numbers. Geopolitical events, including terrorist attacks or significant international conflicts, could lead to increased security measures and altered travel patterns. Furthermore, changes in government travel policies, large-scale public health concerns, or even major disruptions to airline operations (like widespread strikes or natural disasters) could all influence market prices. Any news impacting consumer confidence or travel-related industries will likely be reflected in trading activity.
