Description

This event tracks Costco's customer traffic performance for October 2026 using a specialized index that compares foot traffic to the same month in the previous year. The index accounts for variables like weather and holidays to ensure an accurate year-over-year comparison. Higher values indicate increased traffic compared to the prior year.

Kalshi

All markets in this event resolve based on the Carbon Arc Costco Foot Traffic index for October 2026, with each market setting a different threshold for a 'Yes' outcome. The index measures year-over-year foot traffic changes, where 100 represents equal traffic to the same month last year, with values above 100 indicating growth and below 100 indicating decline. Determination for all markets occurs on the finalized Carbon Arc value recorded at 11:59 p.m. ET on the 7th calendar day after October 2026 ends. The index is derived from mobile location data across over 200 million devices, matched to the same calendar days as the prior year and normalized for seasonality, weather, and holidays. Daily updates occur as new data becomes available, ensuring the final value reflects the most current and accurate measurement of Costco's foot traffic performance for the specified month.

Currently, it's difficult to directly compare prediction market odds to traditional analyst forecasts for Costco foot traffic. While analysts often provide projections for sales and revenue, they rarely offer specific predictions about monthly foot traffic numbers. This market offers a unique, forward-looking perspective based on the collective wisdom of traders, potentially reflecting factors not fully captured in standard financial models. It will be interesting to see if the outcome of this market aligns with or diverges from future analyst reports on Costco's performance.

On Kalshi, this market is priced using a continuous double auction, meaning buyers and sellers set the prices for contracts. The price represents the probability that the event will occur—in this case, that October 2026 foot traffic will exceed a certain level. As more traders buy contracts, the price increases, indicating a higher perceived probability. Conversely, selling pressure lowers the price. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders are attempting to assess the likely impact of economic conditions, seasonal trends, and Costco’s business strategies on foot traffic.

This market resolves around Nov 15, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution will depend on publicly available data regarding Costco’s foot traffic for the month of October 2026. The specific threshold for determining whether foot traffic is considered ‘above’ or ‘below’ the predicted level is defined within the market contract on Kalshi. Traders will be able to see the final outcome and whether their predictions were accurate following the resolution date.

Several factors could influence the price of this market over the next two years. Major economic indicators, such as consumer confidence levels and inflation rates, will likely play a role. Changes in gas prices could also impact shopping habits and foot traffic. Additionally, any significant news regarding Costco’s expansion plans, promotional activities, or competitive landscape could move this market. Unexpected events, like shifts in consumer spending due to broader economic shocks, could also cause volatility in the prices for this market.
