# Fed decision in Dec 2026?

DataSnack's model puts this at 81% seven days from now (10 Nov 2026); the market's number (Kalshi) is 85%. It has no graded forecasts yet; the first is graded on 12 Nov 2026.

## DataSnack's read

**A December hike is priced as the Fed's default; oil and CPI are the brakes**

A hike would show the Fed will keep tightening despite equity stress and weaker sentiment. The model's case rests on the Oct-Jan market moving first, putting the chance at 76% in seven days against 88% now.

## The numbers

- The market's number (Kalshi) now: 85% ([the market](https://kalshi.com/markets/kxfeddecision))
- DataSnack's model, seven days from now: 81%
- The market closes: 9 Dec 2026
- How it resolves: If the Federal Reserve does a Hike of 25bps on December 09, 2026, then the market resolves to Yes.
- Record: It has no graded forecasts yet; the first is graded on 12 Nov 2026.
- Replay on the last 30 days: off by 2.7 points against 2.9 points for standing still; closer on 14 of 30 days
- Fitted on 368 days of history

## How the model works

The December hike chance follows the Oct-Jan market's Pause-Hike-Pause path, which prices a December hike and reacts first to Fed signals. Otherwise it stays where it is.

- About 0.238 in log-odds of each one-day move in the Oct-Jan Pause-Hike-Pause market carries into the December hike chance a week later. DataSnack's author expected 0.28 in log-odds; the data say 0.238 in log-odds ± 0.22, fitted on the same days the replay scores. A rough rule.
