The prediction market will settle according to the rate change following the Federal Reserve's September 2026 FOMC meeting. FOMC, the Federal Open Market Committee, sets U.S. monetary policy. Under the settlement rules, rate changes outside the listed choices are rounded up to the nearest 25 basis points; a 12.5-basis-point cut or hike, for example, is counted as 25 basis points. If no relevant statement has been issued by the end of the meeting, the market settles on rates remaining unchanged. The next FOMC meeting is scheduled for Sept. 15-16, 2026.
