These markets track whether Affirm's credit card spending in October 2026 will exceed specific thresholds relative to the same month in the prior year. The thresholds represent year-over-year growth levels, with higher thresholds indicating greater increases in spending compared to the previous year.
All markets share identical secondary rules and data sources. Finalized Carbon Arc values will be recorded at 11:59 p.m. ET on the 4th calendar day after October 2026 ends. The index measures year-over-year change in Affirm Credit Card Spend using Carbon Arc's aggregated U.S. credit and debit card transaction panel, with 100 representing equal spending to the prior year, values above 100 indicating growth, and values below 100 indicating decline. The panel updates daily with new transaction data matched to the same period of the prior year. Kalshi explicitly states it is not affiliated with Affirm, and all trademarks remain property of their respective owners.
Comparing prediction market probabilities to those from traditional analyst forecasts can reveal interesting insights. Generally, prediction markets often incorporate a wider range of information and perspectives than typical analyst reports, potentially leading to more accurate predictions. If analysts predict a specific range for Affirm credit card spending, this market allows you to see how that compares to the collective wisdom of traders. Discrepancies may arise due to differing assumptions, biases, or access to unique data points. It’s important to consider both sources of information when forming your own assessment.
On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts representing different spending outcomes for Affirm credit cards in October 2026. The price of a contract reflects the market’s assessment of the probability of that outcome occurring. As more traders participate, the price converges towards what the market believes is the fair value. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price movements are driven by supply and demand, with buyers pushing prices up and sellers pushing them down. This dynamic pricing mechanism allows for a fluid and efficient expression of market sentiment.
This market resolves around Nov 12, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution will be based on the total US dollar amount of purchases made on Affirm credit cards during the month of October 2026. The specific data source used for verification will be a publicly available and authoritative financial reporting source. Traders will be able to view the resolution data and confirm the outcome on Kalshi following the resolution date. The final price will reflect the actual spending amount.
Several factors could influence the price of this market leading up to Nov 12, 2026. Major economic indicators, such as consumer confidence, inflation rates, and unemployment figures, could all play a role. Changes in Affirm’s business strategy, marketing campaigns, or partnerships could also impact spending. Unexpected events, like a significant shift in consumer spending habits or a major disruption to the retail sector, could also cause price fluctuations. Any news related to the overall health of the credit card industry or the competitive landscape could also move this market.
