This event tracks projected growth in broadline retail advertising expenditures for a specific month compared to the same month in the previous year. The index value indicates the percentage change, with higher numbers reflecting greater expansion in ad spending. Outcomes depend on whether the reported figure meets or exceeds various predefined thresholds.
All markets in this event resolve based on the Carbon Arc Broadline Retail Ad Spend index for October 2026, measured as a year-over-year comparison. The index compares October 2026 ad spend to October 2025, with 100 representing equal spending. Values above 100 signify growth, while values below 100 indicate decline. Each market has a specific threshold (e.g., above 112, above 129, etc.), and the market resolves to 'Yes' if the finalized index value for October 2026 is above its respective threshold. Determination occurs at 11:59 p.m. ET on the 5th calendar day following the end of October 2026. All markets share identical secondary rules regarding data sourcing, timing, and disclaimers about Kalshi's lack of affiliation with Carbon Arc. The index is a relative measure of ad spend performance, not an absolute dollar value.
Comparing prediction market odds to analyst forecasts reveals how collective intelligence differs from expert opinions. Currently, analysts predict a range of potential outcomes for October’s retail ad spend, with estimates varying based on economic indicators and consumer spending trends. This market allows traders to express their own views, potentially diverging from or aligning with those forecasts. If the market consistently deviates from analyst expectations, it could suggest traders possess unique insights or are reacting to information not yet fully incorporated into traditional analyses. Observing these differences can be valuable for informed decision-making.
On Kalshi, this market is priced using a continuous double auction, meaning traders buy and sell contracts representing different potential outcomes for October’s broadline retail ad spend. The price of each 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. As more traders participate and new information becomes available, the prices adjust dynamically, providing a real-time assessment of expectations. Traders aim to profit by accurately predicting the final outcome and capitalizing on price discrepancies.
This market resolves around Nov 13, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final price will reflect the actual broadline retail ad spend figure for October, as reported by a reputable source. Traders who correctly predicted the outcome will receive a payout based on the final market price and their contract position. This provides a clear and objective determination of the market’s success, based on publicly available data. It’s important to monitor relevant economic indicators leading up to the resolution date.
Several signals or events could significantly move this market before it resolves. Key economic indicators, such as consumer confidence data, retail sales reports, and inflation figures, will all influence trader sentiment. Unexpected changes in these metrics could lead to substantial price adjustments. Additionally, major announcements from key retailers regarding their advertising strategies or earnings reports could also impact the market. Geopolitical events or unforeseen disruptions to supply chains could also play a role, affecting consumer spending and, consequently, retail ad spend. Monitoring these factors is crucial for understanding potential market movements.
