A betting structure where all wagers pool together and payouts are split proportionally among winners after the event resolves. Parimutuel markets bootstrap liquidity without market makers, making them useful for niche or long-tail prediction markets, but face challenges around locked positions, timing, and real-time price readability.

Mauboussin and Callahan review the wisdom of crowds across prediction markets, sports betting markets, parimutuel betting markets, and the stock market, covering each market's history, accuracy, information aggregation mechanism, and failure modes. The key distinction: the three betting markets are zero-sum before costs, while the stock market has positive expected returns over time. Uses the framework to explain why markets efficiently capture known information and where diversity breakdowns create opportunities for excess returns.
Schema Research breaks down the five mechanisms powering every prediction market: LMSR, central limit order books, AMMs, bonding curves, and parimutuel pools. It explains the math behind each, their trade-offs, and how the strongest modern designs combine several mechanisms across different stages of a market's lifecycle.
Launch post for sdk.markets, a toolkit for creating parimutuel prediction markets on arbitrary questions, built on Base. Argues CLOB infrastructure does not fit thin community markets and that parimutuel pools are simpler and fairer when there is no natural counterparty. Details design choices that address parimutuel's classic 'wait and see' sniping problem (short answer windows, snapshot locking, DPM-style pricing) and three resolution modes: single admin, multi-admin consensus, and an AI oracle that resolves from arbitrary URLs.
Traces the parimutuel betting model from its 1867 origins in French horse racing to modern prediction markets. Argues that parimutuel pools solve the cold start problem by bootstrapping liquidity without market makers, but identifies three friction points that need upgrading: locked positions, timing constraints, and price readability.
