Prediction Market vs. Scientific Consensus Spread
Quantifying the gap between expert and market opinion.
Overview
This pillar measures the difference between established scientific consensus and the implied probabilities of prediction markets. It's a powerful tool for identifying potentially mispriced markets in science and technology.
What It Does
It systematically tracks expert forecasts from sources like scientific journals or platforms like Metaculus and compares them to real-money prediction market odds. The pillar calculates the 'spread' or divergence between these two sources. This analysis reveals whether the market is pricing in information that experts might be overlooking or if the market is simply wrong.
Why It Matters
A significant spread can signal a major arbitrage opportunity or reveal hidden information driving market sentiment. It helps you decide whether to position with the experts or with the crowd, providing a clear, data-driven edge in complex technical markets.
How It Works
First, the pillar establishes a baseline probability from a scientific consensus source for a specific event. Next, it pulls the current implied probability from a relevant prediction market. It then calculates the percentage point difference between the two values to create the spread. This spread is tracked over time to identify trends and potential trading signals.
Methodology
The core calculation is the Consensus Spread Percentage (CSP): CSP = (P_market - P_consensus) * 100. P_market is the implied probability from the prediction market (e.g., the price of a 'Yes' share). P_consensus is the aggregated probability from expert sources, such as the community median on Metaculus or a weighted average from recent scientific publications. The analysis is event-based, focusing on the 1-6 months leading up to a key scientific milestone.
Edge & Advantage
This pillar provides a clear signal when the wisdom of the crowd deviates from expert opinion, highlighting markets where emotional bias or niche information may be creating a price dislocation.
Key Indicators
-
Consensus-Market Spread
highThe percentage point difference between the prediction market's implied probability and the scientific consensus.
-
Spread Velocity
mediumThe rate at which the spread is widening or narrowing, indicating shifting momentum.
-
Consensus Stability
mediumMeasures the volatility of the expert consensus over time. A stable consensus with a volatile market is a strong signal.
