With the Federal Reserve's next Federal Open Market Committee (FOMC) meeting scheduled for September 17, traders across futures and prediction markets are overwhelmingly betting on a quarter-point rate cut. Data from the CME FedWatch tool indicates an 89% probability of a 25 basis point reduction to 4.00%-4.25%, while the chance of a larger 50 basis point cut stands at 11%. This near-consensus is echoed by blockchain-based prediction market Polymarket and the CFTC-regulated platform Kalshi, marking a rare alignment across different market instruments.
CME FedWatch: Futures Pricing Signals Clear Path
The CME FedWatch tool computes expectations by analyzing federal funds futures contracts. As of September 6, it assigns an 89% likelihood to a 25bps cut at the upcoming meeting. CME Group operates the world's largest derivatives exchange, and its FedWatch data is widely cited by analysts and media as a benchmark for interest rate expectations. The remaining 11% probability reflects bets on a more aggressive 50bps move, though no scenario of a rate hold or hike registers above zero in the futures market.
Polymarket and Kalshi: Prediction Markets Reinforce Consensus
Polymarket, a decentralized prediction platform, shows 86% of traders betting on a 25bps cut, 11% on a 50bps reduction, and 3% expecting no change. Odds of a rate hike are negligible at less than 1%. The platform, which currently operates internationally, recently announced plans to expand into the U.S. market. Meanwhile, Kalshi — a regulated U.S.-based prediction market — reports an 87% probability for a quarter-point cut, with 11% favoring a larger move and 4% predicting no adjustment. Kalshi's contracts are approved by the Commodity Futures Trading Commission (CFTC), lending additional credibility to its data.
Market Implications and Potential Surprises
The convergence of futures and prediction market data underscores the market's strong belief that the Fed will initiate an easing cycle at this meeting. The consensus is fueled by recent signs of cooling inflation and a softening labor market, as well as Chair Jerome Powell's dovish remarks at Jackson Hole. However, a slim minority of traders still price in a 50bps cut, suggesting that a surprise move could trigger significant market volatility. If the Fed delivers only 25bps but signals a slower pace of future cuts, long-duration assets and cryptocurrencies could face headwinds. Conversely, a larger-than-expected cut would likely boost risk assets across the board.
Overall, the alignment between traditional futures markets and emerging prediction markets provides a unique data point for investors. As the FOMC decision approaches, all eyes will be on the September 17 announcement and Powell's subsequent press conference for clues on the trajectory of monetary policy.
