Traders and LPs add their funds in settlement currency (USDC). The smart contracts exchanges the collateral at the index prices (no slippage) into STUSD, so that traders earn the STUSD yield (see https://www.angle.money/stusd) on their margin, and LPs earn STUSD yield on top of the pool yield.

Prediction Markets

What do the prices mean? Prices reflect odds of 50% Yes and 50% No. When it ends, the correct outcome will be $1 and incorrect $0.

Margin is dependent on current price. Initial max leverage from 2 (at P() = 0.5) to 5 (at P(X) close to 1). P stands for probability. X is a random variable standing for the different outcomes, e.g. X stands for the "Yes" outcome of a particular bet.

Initial Margin and Maintenance Margin Formula is listed in contract specifications below as a function of current market prices.
