These markets track projected year-over-year changes in spending on Southwest Airlines through credit and debit cards in September 2026. The outcomes depend on whether reported spending growth exceeds specific thresholds, with higher thresholds representing larger increases compared to the same month in the prior year.
All markets share a common framework: they resolve based on the first year-over-year change index reported by Carbon Arc for September 2026 Southwest Airlines credit card spend. The index compares spending to the same month in the prior year, with values above 100 indicating growth. Each market has a distinct threshold (e.g., 102, 106, 108, etc.), and the market resolves to Yes only if the reported index exceeds that specific threshold. Once the initial value is reported and the market is settled, any subsequent corrections or revisions do not alter the outcome. The index is derived from Carbon Arc’s aggregated U.S. credit and debit card transaction panel, updated daily. Kalshi explicitly disclaims any affiliation with Southwest Airlines or Carbon Arc, and all trademarks remain the property of their respective owners.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, traders determine prices through continuous bidding and asking, with the current top outcome reflecting the most likely scenario as assessed by participants. The implied probability offers a snapshot of collective expectations, adjusted for recent news, financial performance updates, and broader economic signals influencing consumer credit spending patterns.
This market resolves around Oct 14, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final determination will rely on officially released financial data and widely accepted sources that detail Southwest Airlines' credit card spend for the September period.
Several signals could shift this market before it settles, including major economic announcements, changes in consumer confidence, Southwest Airlines earnings releases, and any significant promotional campaigns or partnerships involving their credit card program. Unexpected macroeconomic developments or sector-wide trends in travel and spending may also cause rapid repricing as traders adjust their positions.
