What Most People Get Wrong About Prediction Markets

Jeff Park rebuts Axios/MorePerfectUS coverage framing prediction markets as gambling/social ill. Thesis: 'investing vs gambling' is defined by +EV of the player, not the game. PMs are stochastic with a deterministic component — like poker, +EV for high-agency players. Two distinctive features: Precise (cleanest basis risk to truth) and finite Expiry. Professional market makers won't provide liquidity on info-asymmetric markets, so insider-trading fears are overblown. Media hostility to PMs is institutional self-preservation, not principled critique — because PMs threaten the bid-ask spread on consensus.
