The FED interest rates are defined in this market by the upper bound of the target federal funds range. The decisions on the target federal fund range are made by the Federal Open Market Committee (FOMC) meetings.
This market will resolve to “Yes” if the there are 8 or more cuts of 25 basis points by the Fed's December meeting (including any cuts made during Dec meeting). Otherwise, this market will resolve to “No.”
For example, if the FED cuts rates by 50 bps after a meeting, it would be considered 2 cuts (of 25 bps each).
Note that cuts between 1-24 bps (inclusive) will also be considered 1 rate cut.
