Fed Rate Prediction Markets

Three Sources, One View

Federal Reserve rate decisions move trillions of dollars in global markets. Until now, tracking the odds meant checking the CME FedWatch tool — a useful but limited view based on Fed Funds futures. Prediction markets on Kalshi and Polymarket now offer a second and third opinion, often pricing FOMC outcomes differently than CME.

Oddpool is the only platform that compares all three. Our Fed Rate Monitor shows CME FedWatch probabilities alongside Kalshi and Polymarket odds for every upcoming FOMC meeting — so you can see where the bond market, the regulated prediction market, and the crypto prediction market agree or disagree.

How Fed Rate Contracts Work

Each FOMC meeting gets its own set of contracts. A typical meeting might have three contracts: "Fed holds rates," "Fed cuts 25bps," and "Fed cuts 50bps." Prices across the three sum to roughly $1.00, and each price reflects the crowd's implied probability of that outcome. If the "hold" contract trades at $0.65, the market sees a 65% chance the Fed stands pat.

Beyond individual meetings, you can also trade on the total number of rate cuts in a year — contracts like "3 or more cuts in 2026" or "zero cuts in 2026." These longer-horizon contracts carry significant volume and are closely watched by bond traders and macro hedge funds.

Why Prices Differ Across CME, Kalshi, and Polymarket

CME FedWatch probabilities come from institutional bond traders pricing Fed Funds futures. Kalshi odds come from a CFTC-regulated event contract exchange with a mix of retail and institutional participants. Polymarket odds come from crypto-native global traders. Each venue has a different audience, different capital, and different information flow.

When all three agree, the probability is well-established. When they diverge, it signals genuine uncertainty — or a potential arbitrage opportunity. A 5-cent gap between Kalshi and Polymarket on the same FOMC outcome means you can lock in a 5% return by taking opposite sides on each venue.

What Moves Fed Rate Odds

Fed rate probabilities shift in response to economic data releases: CPI (inflation), jobs reports, GDP prints, and Fed governor speeches. A hotter-than-expected CPI print can crash rate-cut odds within minutes. Oddpool tracks these movements across all three sources, and the Whale Tracker flags large trades on FOMC contracts — giving you early signal when institutional money repositions ahead of data releases.

The Fed Rate Monitor also includes economic indicators like CPI trends, unemployment data, and GDP growth alongside the rate probabilities, so you can see the data driving the odds without switching between financial news sites.
