Market Maker
A trader who provides liquidity by simultaneously buying and selling assets, profiting from the bid-ask spread while stabilizing market prices.
Market makers profit by buying low and selling high simultaneously. On Uniswap, market maker deposits 50 ETH and 100,000 USDC. When someone buys ETH at $2,010, market maker buys at $2,000, sells at $2,010, pockets $10. Market makers capture bid-ask spread. Earn from spread repeatedly—thousands of trades daily. Market makers provide crucial liquidity enabling others to trade. Competitive market making drives tight spreads. Sophisticated market makers use algorithms, data, and capital to maximize profits. Market makers are core infrastructure of modern markets.
Market Making Economics
How profits work:
Bid-Ask Spread: Difference between buy price (bid) and sell price (ask).
Example: ETH trading at $2,000 bid (buy at $2,000), $2,010 ask (sell at $2,010).
Spread: $10 per trade × 100 trades/day = $1,000 daily profit from spread.
Volume: More volume = more spread collection. High-volume market makers earn significant revenue.
Holding Risk: If price moves >spread while holding, loses money. Market making has risk.
Market making profits from spread capture.
Market Maker Strategies
Different approaches:
Passive Liquidity Provision: Provide liquidity, accept whatever trades come. Lower profit but simpler.
Active Quoting: Quote aggressive prices to attract trades. Higher profit but more capital.
Algorithmic MM: Use algorithms adjusting prices based on market conditions. Most sophisticated.
Statistical Arbitrage: Identify mispricings, provide liquidity exploiting them. High skill.
Order Flow: Try to identify and profit from order flow patterns. Most advanced.
Different strategies have different risk/reward profiles.
Liquidity Pools as Market Makers
DeFi market making:
AMM Pools: Uniswap, Balancer pools are market makers. Capture trading fees.
LP Returns: LPs earn from trading volume. ETH/USDC pool with $100M trading daily @ 0.3% fees = $300k daily revenue split among LPs.
Impermanent Loss: LPs suffer IL when prices move dramatically. IL can exceed fee revenue.
Capital Efficiency: Modern pools use concentrated liquidity (Uniswap V3) improving capital efficiency.
DeFi market making is accessible to anyone with capital.
Professional Market Making
Institutional approaches:
Trading Firms: Firms with billions in capital running market making operations.
Prime Brokerage: Access to leverage, financing, and sophisticated tools.
High Frequency: Exploit microsecond advantages through speed and algorithms.
Statistical: Use statistical methods identifying profitable opportunities.
Proprietary: Firms develop proprietary algorithms giving edge.
Professional market making is sophisticated industry.
Market Making Risks
Potential downsides:
Inventory Risk: Holding assets exposes to price movements.
Model Risk: Market making algorithms might malfunction.
Liquidity Risk: Can't exit position fast enough, forced to realize loss.

Regulatory: Market making subject to regulatory scrutiny.
Market making is risky despite seeming simple.
