Fed rate cut odds look different after September's hike. Here's how to read a Fed decision market and check the number across platforms before you rely on it.

TL;DR
Searching for fed rate cut odds and expecting a simple yes or no? The number depends on which meeting you mean, and the question has flipped since the summer. The Federal Reserve raised its target range by a quarter point on September 16, 2026, to 3 3/4 to 4 percent. A cut at the next meeting would be a reversal, so prediction markets price it as one outcome next to hold and hike.
This guide shows how to read that split, where the live prediction market data comes from, and what to check before you trust it.
They measure how likely the committee is to reverse course, and that is a harder call than continuing a trend. The FOMC decides at every meeting, so a cut is always possible. After a hike, though, it takes new data to move the cut outcome off the bottom of the board.
The October meeting is the cleanest read. On the October 27 to 28 decision, the market currently prices a hold at 93.8% and a cut at 0.6%.
Those two numbers update on their own. Read them together, because a falling hold price only means something if you can see which outcome picked up the difference.
The December meeting works differently. It comes with a Summary of Economic Projections, so the December contract has a scheduled catalyst the October one lacks. Right now the December cut outcome sits at 25.1%.
Each outcome trades between $0 and $1, and the price is the market's implied probability. A $0.70 hold means the market gives a hold a 70% chance. Nobody polled anyone. Traders with money on the line set the price.
Because one meeting can only end one way, the cut, hold and hike prices should add up to about 100%. When they total noticeably more, you are looking at the same gap explained in our guide to prediction market overround.
Two details matter more than the headline number. First, what counts as a cut: the size of the move and the date the decision is announced both decide how a contract resolves, so read the rules before you rely on a price.
Second, how much trading sits behind it. A price with deep volume and a one-cent spread is a consensus. A price with thin volume is closer to a few opinions, and liquidity differs a lot between platforms.
Polymarket rate cuts markets show the same meeting through a different crowd. Polymarket runs its own order book and its own trader base, so its price for a cut can sit a few points away from the same outcome elsewhere.
That gap is normal. It does not mean one platform is wrong. Each venue has its own traders and liquidity, and its own rules for how a contract settles. That is the subject of our piece on why odds disagree across platforms.
Kalshi lists its own Fed decision contracts as a CFTC-regulated exchange, and its price can differ from Polymarket's for the same reasons.
Opinion focuses on macro contracts, so its board is worth checking for the same meeting. Limitless and Predict.Fun round out the five platforms PredictionHero tracks.
Which Fed contracts each one lists changes over time, so look at every board directly. PredictionHero normalizes prediction market data from the markets it covers onto one screen, which makes the spread between platforms easy to see without opening five tabs.
They are two separate reads on the same question. Tools such as CME FedWatch derive their probabilities from fed funds futures prices. Prediction markets get theirs from contracts that traders buy and sell directly.
Futures are an institutional hedging market. Prediction market contracts are simpler, sized for individuals, and tied to a single clear outcome.
When the two disagree, find out why before you decide either one is wrong. A gap can come from a different resolution definition or from a price that has not caught up to news yet.
Run through five checks, in this order.
What moves these prices most is data. Inflation prints are the clearest example, and the way CPI contracts price a release is worth reading next to any Fed odds you track.
They change throughout the day, so use the live prediction market data in this article rather than a number copied from another page. After the September hike, a cut sits as one outcome next to hold and hike, and the live prices show exactly how the market weighs them right now.
Yes. The FOMC votes at every meeting, so a reversal is always procedurally possible. A cut after a hike usually needs a clear change in inflation or growth data. Prediction markets price how likely that change is, meeting by meeting, rather than assuming any path.
The Federal Reserve's 2026 calendar lists October 27 to 28 and December 8 to 9. Only the December meeting is paired with a Summary of Economic Projections. Check the Fed's own calendar before you rely on a date, since schedules can change.
No single platform wins on every count. Polymarket, Kalshi, Limitless, Predict.Fun and Opinion each run their own order book and trader base. Compare volume and spread on each board, read each platform's resolution rules, and treat agreement across platforms as a stronger signal than any one price.
No. CME FedWatch derives its probabilities from fed funds futures prices. Prediction market odds come from contracts that traders buy and sell directly. They often point the same way, but they are separate measurements, and a gap between them is worth investigating.
