What is Optimism Tax?

Analysis of 72 million prediction market trades ($18B volume) reveals takers (impulsive buyers) lose 1.12% on average, while makers (patient sellers) gain 1.12%. People systematically overpay for 'YES' outcomes: at 1-cent prices, YES contracts return -41% while NO contracts return +23% - a 64 percentage point gap for equivalent odds.

Practical Application

For VCs: LPs who chase hot sectors (AI, crypto, climate) during boom cycles exhibit taker behavior and pay the Optimism Tax. Top GPs act as makers - deploying patient capital, setting terms, and profiting from emotional market cycles. Don't invest in the YES case. Structure around the NO case.
