How Real GDP (Advance) Moves Fed Rate Prediction Markets
Advance estimate of real Gross Domestic Product growth, quarterly annualized.
GDP contraction is the textbook recession signal. Two consecutive negative prints trigger maximum dovish pressure on the Fed. Strong GDP reduces the urgency to cut.
The Bayesian Sensitivity Model
The model calibrates a sensitivity coefficient for each indicator: how many percentage points the odds at the next FOMC meeting shift toward a hike or a cut per standard deviation of surprise. For GDP, the preliminary coefficient is ±+/- 2–5pp on next-meeting odds. This means ifGDP comes in 1 standard deviation above consensus (hawkish surprise), the model shifts the odds toward a hike by approximately +/- 2–5pp on next-meeting odds.
These coefficients are preliminary until calibrated from at least 20 historical observations of Kalshi price reactions to each release. The calibration uses a regression of (surprise_zscore × sensitivity_coefficient) against observed Kalshi probability changes, cross-validated against CME FedWatch data going back to 2015.
