How to Predict a Stock Market Crash

Predicting stock market crashes is notoriously difficult, but prediction markets offer one of the most reliable approaches by aggregating the views of thousands of traders who monitor leading indicators in real time. Rather than relying on a single crash indicator, markets synthesize them all.

Traditional crash indicators include the yield curve, credit spreads, margin debt levels, put/call ratios, insider selling patterns, and valuation extremes. Prediction markets supplement these by adding geopolitical risk, policy uncertainty, and sector-specific stress signals into a single probability estimate.

The best approach is to use prediction market crash probabilities as your base rate and then apply your own analysis on top. If markets say 15% crash probability and you have strong reasons to think it should be higher, that may be a hedging opportunity. The current crash probability data is shown in the markets below.
