The Fed, venue against venue

Fed decision in Dec 2026

The same meeting priced on two venues. A gap of more than a few points is a disagreement between two sets of traders, or a difference in how each contract resolves; either is worth knowing before quoting one of them.

How to read a price

Each contract pays $1 if the event happens, so its price reads as the market’s probability: 64¢ is 64%. It is what the last traders paid, not a forecast by anyone in particular. Thin books move on small money, and a contract’s resolution rule can differ from the question as you would ask it; open the market before you quote it.

The week’s move is in percentage points against the price about seven days earlier. For a ladder of levels (CPI above 3.5%, above 3.6% …) the page prints the level the market puts at even odds, interpolated between the two rungs either side of 50%.
