Mechanism · SP
Sportsbooks
Sportsbook mechanics · peer-to-pool, positional AMM, or CLOB · applied specifically to sports outcomes. Distinct audience cluster.
Also known as: Onchain sportsbooks · Decentralized sports betting · Peer-to-pool sportsbooks
In plain terms
A regular sportsbook but with onchain settlement and pooled LPs instead of a centralized bookmaker.
How it works
Sportsbook odds (moneyline, spread, totals, parlays) settled onchain. Liquidity from peer-to-pool LPs (Azuro), positional AMM (Overtime), or onchain CLOB (Monaco, SX). Oracle from Chainlink Sports or designated resolution authorities.
How to identify it
Sports-only inventory; sportsbook-style odds (decimal/moneyline) not $0–$1 shares; peer-to-pool LP economics or positional AMM.
Common confusion
Sometimes shelved as 'prediction markets' because outcomes are predictions · but the mechanism and economics are sportsbook, not PM.
