These markets track potential growth in U.S. based consumer credit and debit card spending for a specific month in 2026, compared to the same month in the previous year. The outcomes depend on whether reported spending exceeds various growth thresholds.
All markets share a common framework: they resolve based on the first value reported by Carbon Arc for the BP Monthly Credit Card Spend index for September 2026. The index reflects year-over-year changes in U.S. credit and debit card transactions, with 100 representing equal spending to the prior year, values above 100 indicating growth, and values below 100 indicating decline. Each market has a specific threshold; if the reported index exceeds that threshold, the market resolves to Yes, otherwise No. Post-settlement corrections or revisions to the reported data do not alter the outcome. The underlying data comes from Carbon Arc's aggregated transaction panel, updated daily, and Kalshi disclaims any affiliation with Carbon Arc.
This market resolves around Oct 14, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final determination will hinge on officially released data, ensuring an objective and transparent resolution process that matches the market’s underlying event specifications.
Key signals that could shift this market include major economic announcements, changes in oil prices, shifts in consumer confidence surveys, and any unexpected disruptions to BP’s credit card processing network. Additionally, broader macroeconomic trends or policy changes affecting consumer spending may also influence trader sentiment and price movements leading up to resolution.
