Kalshi
This set of markets tracks the performance of sporting goods advertising expenditures for a specific month and year, comparing them against the same period in the previous year. The index value indicates growth or decline relative to the prior year, with higher values signifying increased spending. Each market corresponds to a different threshold, allowing participants to assess the likelihood of ad spend exceeding various levels.
All markets in this event are determined by the Carbon Arc Sporting Goods Ad Spend index for September 2026, reported on a year-over-year basis where 100 represents equal spending to the same month last year. Each market resolves to 'Yes' if the reported index value exceeds a specific threshold (ranging from 60 to 84). The determination for all markets is based solely on the first value reported by Carbon Arc, with any subsequent corrections or revisions disregarded for settlement purposes. The index measures growth (values above 100) or decline (values below 100) relative to the prior year, and Kalshi explicitly disclaims any affiliation with Carbon Arc or ownership of related trademarks and branding.
Currently, the prediction market offers a different perspective than traditional analyst forecasts for sporting goods ad spend. While analysts often provide point estimates or ranges, this market allows for a probabilistic view, showing the collective wisdom of traders. Discrepancies may arise due to differing methodologies, access to information, or biases inherent in each approach. It’s important to consider that prediction market prices reflect real money at stake, potentially making them a more accurate signal of expected outcomes than forecasts based solely on expert opinion.
On Kalshi, this market is priced through a continuous double auction, where traders buy and sell contracts representing their beliefs about the final sporting goods ad spend amount. The price of a contract reflects the probability of that outcome occurring. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders set the odds based on their own research, information, and risk tolerance, creating a dynamic and evolving price discovery process. As new information becomes available, the price will adjust to reflect the changing consensus of market participants, offering a real-time assessment of expectations.
Several signals or events could significantly move this market before Oct 13, 2026. Major economic indicators, such as consumer confidence reports or retail sales data, could influence expectations about spending. Announcements from key sporting goods retailers regarding their marketing plans or financial performance would also be impactful. Unexpected events like major sporting events being canceled or postponed, or shifts in consumer preferences towards specific sporting goods categories, could also cause the market to react. Any news that alters the outlook for the overall economy or the sporting goods industry has the potential to shift trader sentiment and prices.
