Public Betting Percentage Fade

Overview

A contrarian pillar that identifies overvalued favorites in MLB games. It systematically bets against teams that the general public is overwhelmingly backing, particularly on the Run Line.

What It Does

This pillar analyzes public betting percentage data across major sportsbooks to pinpoint lopsided markets. It flags MLB games where more than 75% of bets are on one side of the Run Line. The core assumption is that such heavy public backing inflates the line, creating hidden value on the less popular, underdog side.

Why It Matters

The general public often positions on popular teams and narratives, not statistical value. This pillar exploits that tendency by capitalizing on the artificially good odds exchanges offer on the other side to balance their financial risk.

How It Works

First, the pillar aggregates public bet counts and money percentages for all MLB Run Line markets. It then identifies games where the bet percentage on one team exceeds a 75% threshold. Finally, it analyzes line movement to confirm the shift is due to public volume, signaling a prime opportunity to 'fade the public'.

Methodology

The primary metric is the 'Public Consensus Score', calculated as the average bet percentage on a team's Run Line from three major data providers. A score over 75% triggers an alert. The system also watches for 'Reverse Line Movement', where the betting line moves contrary to the public money, which can indicate sharp bettors are on the other side.

Edge & Advantage

This gives an edge by systematically finding and betting on numbers with positive expected value (+EV) that are created by casual bettor bias.
