What Does 'Round-Number Bias' Mean?

[ SLANG ][ PREDICTION MARKETS ][ DEGEN FINANCE ]

FORCE: Degen EconomyUNIVERSE: Prediction-Market TradingCLUSTER: Trading Strategy

A systematic pricing distortion in prediction markets where contracts clustered around round-number thresholds (like exactly 50% or a milestone figure) trade less efficiently than non-round values, exploitable by traders who account for it.

REAL-WORLD EXAMPLE

"There's a real round-number bias around the fifty-cent mark, contracts just don't price efficiently right there."

LORE & ORIGIN

Discussed in prediction-market quant communities as a documented behavioral pricing quirk, where traders anchor psychologically to round numbers in ways that create measurable inefficiencies.
