The market tracks Walmart's credit card spending trends for September 2026, comparing it against various thresholds to gauge consumer behavior and financial performance relative to the previous year.
All markets resolve based on the Carbon Arc Walmart Credit Card Spend index for September 2026, with outcomes determined by whether the reported value exceeds specific thresholds (94, 96, 98, 100, 101, 102, 104, 106, or 109). The index reflects year-over-year changes in spending, where 100 indicates no change from the prior year, values above 100 show growth, and values below indicate decline. The determining value is the first report by Carbon Arc, and any subsequent corrections or revisions do not affect the resolution. The index is derived from aggregated U.S. credit and debit card transaction data matched to the same period of the previous year, updated daily.
Compared to traditional analyst forecasts, this market’s odds reflect a collective trader assessment of Walmart credit card spend expectations. While analysts may issue detailed reports based on historical data and economic indicators, the prediction market incorporates real-time sentiment and can react quickly to new information, sometimes showing divergence from consensus estimates.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, traders determine the price through continuous bidding and order matching. The current implied probability reflects the collective view of participants about the likely outcome range for Walmart credit card spend in September. This dynamic pricing adjusts throughout the trading period based on new economic data, retail performance news, and overall market conditions.
This market resolves around Oct 14, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final settlement will reflect officially reported figures for Walmart’s credit card spend during September, providing a clear and objective basis for resolving all positions.
Key signals that could shift this market include major economic announcements, changes in consumer confidence, quarterly retail sales reports, and any significant developments in Walmart’s financial performance or credit card program. Additionally, broader macroeconomic trends or policy changes affecting consumer spending may also influence trader expectations and move the odds before resolution.
