Fed Decision in December?

Polymarket’s December Fed decision market asks how much the upper bound of the target federal funds range will change at the Federal Reserve’s December 2026 meeting. A 25-basis-point increase leads the available outcomes. That pricing reflects traders’ expectations; the policy decision remains unresolved.

What the market measures

The contract compares the target range’s upper bound after the December meeting with its level before that meeting. It measures the size and direction of that change, rather than the absolute rate level or the tone of the Fed’s accompanying commentary.

The five outcomes are a decrease of at least 50 basis points, a 25-basis-point decrease, no change, a 25-basis-point increase and an increase of at least 50 basis points. A basis point is one hundredth of a percentage point, so a 25-basis-point move equals 0.25 percentage points.

How to read the leading outcome

At review, the source displayed approximately 87% for a 25-basis-point increase and 7% for no change. Both decrease outcomes were below 1%, while an increase of at least 50 basis points was around 5%. These are a time-specific view of market pricing and can change before settlement.

The distribution favors a modest increase over either holding rates steady or making a larger move. It does not establish why traders hold that view, nor does it confirm that policymakers have decided to raise rates. A high implied probability still leaves room for another outcome.

Resolution rules and timing

The source rules identify the FOMC statement following the December 8–9, 2026 meeting as the resolution source. The market may resolve as soon as that statement supplies the relevant information. The Federal Reserve’s published target-range data also provides a reference for the rate level and change.

If the change does not match the displayed increments, the rules round it up to the nearest 25 basis points and assign the relevant bracket. The source gives a 12.5-basis-point cut or increase as an example that counts as a 25-basis-point move.

If no statement is released by the end date of the next scheduled meeting, the contract resolves to the no-change bracket. This fallback is distinct from an ordinary decision to leave the target range unchanged.

What would change the assessment

The decisive evidence is the official change to the target range’s upper bound. Economic releases and Fed communications may influence expectations before the meeting, but they do not settle this contract by themselves. Readers should distinguish a change in market prices from an announced policy action and consult the latest odds alongside the complete source rules.
