Can prediction markets be good for society?
Summary
Finn Brunton discusses his Harper’s Magazine piece on prediction markets, contrasting Robin Hanson’s utopian vision of collective wisdom with Timothy May’s crypto-anarchist goal of destroying institutional trust. Brunton argues that current platforms like Polymarket function as glorified gambling dens that enable dangerous manipulation, such as threats against journalists to rig geopolitical outcomes. He proposes banning anonymous bets to curb insider trading and restore the markets’ potential as a tool for aggregating expert insight and guiding societal decision-making.
