Market-Poll Convergence Velocity

Overview

This pillar measures the time it takes for prediction market prices to reflect new political polling data. It's valuable for identifying trading opportunities before the market fully absorbs new information.

What It Does

It continuously monitors major polling aggregators and the corresponding odds on political prediction markets. When a new poll is released, the pillar calculates the time lag until market prices stabilize. It also analyzes the magnitude of the price shift relative to the poll's sample size and historical accuracy.

Why It Matters

This analysis reveals the market's efficiency in processing new information. A slow convergence time suggests a window to trade on new data before it is fully priced in, while a rapid overreaction might signal a chance to fade the initial move.

How It Works

First, the system ingests new poll data from key aggregators, noting the exact publication timestamp. It simultaneously tracks real-time odds for the relevant political market. The pillar then calculates the time delta between the poll's release and the point where market odds reach a new, stable equilibrium, flagging any significant delays or overreactions.

Methodology

The core metric is Convergence Time (CT), calculated as T_stable minus T_poll, where T_poll is the poll's release timestamp and T_stable is when market price volatility drops below a 5% threshold for 15 consecutive minutes. Reaction Magnitude (RM) is calculated as the absolute change in price divided by the poll's reported shift in support. Polls are weighted by their pollster's historical accuracy rating.

Edge & Advantage

It provides a quantifiable measure of market inefficiency, allowing traders to systematically capitalize on the lag between information release and price discovery.
