Kalshi's First Research Report Released: How Collective Intelligence Outperforms Wall Street Think Tanks in Predicting CPI

Kalshi Research's inaugural report demonstrates that prediction markets consistently outperform Wall Street consensus forecasts in predicting the U.S. year-over-year CPI inflation rate. The study, covering over 25 monthly CPI releases from February 2023 to mid-2025, shows Kalshi’s market-implied forecasts had a 40.1% lower mean absolute error (MAE) than consensus predictions across all environments. The advantage was most pronounced during economic "shocks." For large surprises (over 0.2 percentage points), Kalshi's forecasts were 50% more accurate a week before the data release, improving to 60% more accurate the day before. For medium surprises (0.1-0.2 percentage points), the advantage was similarly 50%, rising to 56.2% closer to the release. Crucially, a divergence of over 0.1 percentage points between the market forecast and consensus served as a strong signal, with an 81.2% probability that a shock would occur. When the two forecasts disagreed, the market prediction was more accurate 75% of the time. The report attributes this "Shock Alpha" to three factors: the "wisdom of crowds" aggregating diverse information, superior incentive structures that reward accuracy over conformity, and more efficient information synthesis, even with the same public data. This suggests prediction markets provide a valuable, differentiated signal for investors and policymakers, especially during periods of high uncertainty.
