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.

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.
