Every FOMC decision reprices bonds, equities, real estate, and currencies. Prediction markets give you a real-time, money-weighted probability for each possible outcome. Not a survey. Not a model. Actual money on the line. Here is how to read it.
In prediction markets, the price of an FOMC contract directly represents the market-implied probability of a specific rate decision. A contract at $0.65 = 65% probability. Kalshi lists binary yes/no contracts for each FOMC meeting priced $0.01 to $0.99. Polymarket groups Fed decisions as multi-outcome events.
As of March 12, 2026, both platforms price the March 18 FOMC hold near 100%. Markets price exactly one rate cut in 2026 as the most likely outcome. Framework: above 80% is strongly priced in, 50-80% is the actionable signal zone, below 30% watch for rapid moves. April 10 CPI is the next repricing catalyst.
Two platforms matter.
Kalshi lists contracts for every upcoming FOMC meeting. Each contract is binary: yes or no on a specific outcome. "Will the Fed cut rates by 25bps or more in June 2026?" Prices range from $0.01 to $0.99. That price is the probability. A contract at 72c means the market puts a 72% chance on that outcome.
Polymarket groups Fed decisions as multi-outcome events. You see rate cut, rate hike, and pause probabilities side by side. Prices are order-book based, updating continuously. The interface shows you the full distribution of expected outcomes for each meeting.
Both are useful. The best signal comes from watching both. When they agree, the probability is high-confidence. When they diverge, something interesting is happening in the liquidity or trader composition.
A contract priced at $0.72 means the market believes there is a 72% chance that outcome happens. Here is the framework for interpreting every price level.
The price IS the probability. A contract at 42c means the market puts a 42% chance on that outcome. No conversion needed. No model required. The number is the signal.
Four things reprice the Fed distribution.
Economic data releases. A hot CPI print can shift rate cut odds by 10 to 15 points in minutes. Jobs, GDP, PCE. All move the needle. The February 2026 CPI print on March 11 confirmed the hold probability near 100%. Prediction markets had that priced weeks ahead.
Fed speeches and minutes. Markets parse every word. Hawkish language pushes cut odds down. Dovish pushes them up. The reaction is instant on both Kalshi and Polymarket.
Global events. A banking crisis, geopolitical shock, or commodity spike changes the Fed's calculus fast. Prediction markets reprice before the headlines catch up. The Iran oil shock in late February moved recession odds 9 points in 48 hours, and rate cut expectations shifted with it.
Feedback loops. Bond yields, Fed funds futures, and prediction markets all influence each other. Watch for divergences between prediction market pricing and CME FedWatch. That is where the edge lives.
Compare across platforms. If Kalshi shows 65% for a rate cut and Polymarket shows 72%, that gap might signal different trader populations or liquidity conditions. The average is usually your best estimate.
Watch the 24-hour delta. A 5-point shift in a single day is significant. New information entered the market. If you are not tracking overnight moves, you are showing up late.
Do not ignore tail risk. A 10% chance of a surprise rate hike is still 1-in-10. That is enough to consider tail-risk hedges, especially in options.
Time your reads. Prediction markets are most informative right before and right after major data releases. Check odds the morning of a CPI print, then again 30 minutes after. The delta tells you how the market interpreted the data, often differently than the headline.
The March 18 FOMC hold is near 100%. Core CPI at 2.5%, shelter still the largest monthly driver, food at 3.1% YoY. The committee has no opening to cut. Markets priced this weeks ago.
The more useful question is what comes after. Prediction markets currently price exactly one rate cut in 2026 as the most likely full-year outcome. But that distribution will reprice as the April 10 CPI print comes into view. That will be the first data to capture the Iran oil shock in the energy basket.
This is the setup to watch. The distribution the market builds between now and April 10 is the trade.
