The Secured Overnight Financing Rate (SOFR) is a key benchmark interest rate used in the U.S. financial markets, reflecting the average overnight repurchase agreement rate secured by U.S. Treasury securities. Predicting SOFR for a specific future date involves analyzing economic indicators, monetary policy decisions, and market expectations. These markets allow participants to bet on whether the rate will fall within certain precise thresholds, offering a granular view of future interest rate expectations.
The event resolves based on the initially reported Secured Overnight Financing Rate (SOFR) for October 19, 2026, as published in the “Secured Overnight Financing Rate Data” table under the column labeled “Rate (%)”. All markets share this same underlying data source and rule that later revisions to the reported SOFR will not affect the outcome. Each market has a specific resolution condition: one market resolves if the rate is at most 3.85%, six markets resolve if the rate matches exactly 3.86%, 3.87%, 3.88%, 3.89%, 3.90%, or 3.91%, and the final market resolves if the rate is at least 3.91%. The exact value of the SOFR on that date determines which market settles as the winner, with only one market resolving to “Yes” based on the precise figure reported.
Currently, it's difficult to directly compare the odds in this market to specific analyst forecasts for the SOFR rate in October 2026. However, prediction markets often aggregate a diverse range of perspectives and can reflect real-time adjustments to expectations based on incoming economic data. If analysts generally anticipate a stable interest rate environment, we might see higher probabilities assigned to outcomes near the current SOFR level. Conversely, if forecasts suggest significant shifts, this market will likely reflect increased probabilities for higher or lower rates. It’s a dynamic comparison.
On Kalshi, this market is priced using a continuous double auction, meaning traders can buy and sell contracts representing different SOFR rate outcomes at any time. The prices reflect the collective assessment of market participants regarding the likelihood of each outcome. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate and new information becomes available, the prices will adjust to reflect the evolving consensus. The market depth shows the volume of contracts available at various price points, providing insight into the level of conviction behind different predictions.
This market resolves around Oct 27, 2026, with the outcome confirmed once the actual SOFR rate for October 19, 2026 is verifiable from credible public reporting. The market will pay out to the contracts corresponding to the actual SOFR rate published by the Federal Reserve Bank of New York. The exact payout value will depend on the price of the winning contract at the time of resolution. Traders should monitor official announcements from the Federal Reserve for the definitive SOFR rate.
Several key economic signals and events could significantly impact this market. Changes in inflation data, particularly the Consumer Price Index (CPI) and the Personal Consumption Expenditures (PCE) price index, will be closely watched. Federal Reserve policy announcements, including any indications of future interest rate adjustments, will also be major drivers. Unexpected economic shocks, such as geopolitical events or significant shifts in employment figures, could also cause substantial movements in the probabilities reflected in this market. Overall economic growth and any changes in the Federal Reserve's outlook will be crucial.
