## What Is Prediction Market Consensus?

Prediction market consensus is the aggregated probability of an
event occurring, calculated by combining prices across multiple
regulated prediction markets. Consensus is more accurate than any
single market because it pools information from all participants
across all venues and removes platform-specific biases.

Meridian Edge computes consensus by:
1. Collecting prices from 25+ regulated prediction markets
2. Removing the vig (devigging YES/NO so they sum to 100%)
3. Volume-weighting each source's contribution
