Fixed Product Market Maker
Every CalledIt prediction market operates using a smart contract–based pricing mechanism called a Fixed Product Market Maker (FPMM). This system is responsible for setting and updating share prices in real time, based entirely on market activity.
Unlike traditional betting platforms, CalledIt does not rely on peer-to-peer matching or centralized odds-setting. Instead, the FPMM provides continuous liquidity, allowing shares to be bought or sold at any time prior to market lock, regardless of whether another participant is on the other side of the trade.
