How Markets Work

Prediction Markets

Prediction markets allow you to trade on the outcome of future events. Prices reflect the collective wisdom of participants.

Outcome Shares

Each market outcome is represented by ARC-200 tokens. If your outcome wins, each share is worth 1 unit of collateral.

Market Resolution

Markets are resolved by designated resolvers based on objective criteria. Disputes can be raised during the dispute window.

Pricing Engines

LMSR (Logarithmic Market Scoring Rule)

Provides consistent liquidity and smooth price discovery. Better for markets with uncertain outcomes.

CPMM (Constant Product Market Maker)

Simple x*y=k formula familiar from AMMs. More predictable slippage but can have liquidity gaps.

Choosing an Engine: LMSR is recommended for most markets. CPMM works well for binary markets with high confidence in outcomes.

Implied Probability

1%
Trading Fee

0.3%
Slippage

Price impact from your trade size

Price Calculation

Outcome share prices represent implied probabilities. A 72% price means the market estimates a 72% chance of that outcome occurring.

Profit & Loss

If you buy YES shares at 72¢ and the outcome is YES, you earn 28¢ per share (100¢ - 72¢). If NO wins, you lose your 72¢ investment.

Liquidity Provision

Earn fees by providing market liquidity

How It Works

Liquidity providers deposit collateral to enable trading. In return, they earn a share of trading fees proportional to their contribution.

Risks & Rewards

LPs earn fees but face impermanent loss risk if market probabilities shift significantly. Consider market volatility before providing liquidity.

Adding/Removing Liquidity

Add liquidity pro-rata to current market probabilities. Remove anytime, receiving your proportional share of remaining liquidity.
