What is Market Maker?
Crypto Glossary Definition
An individual or company that quotes a buy and a sell price, hoping to make a profit on the bid–ask spread. Also known as a liquidity provider.
Why Market Maker Matters
A market maker continuously places both buy and sell orders to keep an exchange's order book liquid, profiting from the small spread between them. Healthy market-maker activity is part of why major coins have tight bid-ask spreads while obscure micro-caps often don't.
Market Maker in Practice
An exchange wants to list a newly launched token but knows that without existing trading activity, the order book will be empty and unusable — anyone trying to buy would face a massive spread between the lowest ask and highest bid. To solve this, the project partners with a professional market-making firm, which agrees to continuously place both buy and sell orders around the token's fair value, say $1.00, perhaps bidding at $0.995 and offering at $1.005. As regular traders start buying and selling, the market maker's orders are what they actually trade against, and the firm profits from the small half-cent spread captured on each round trip, multiplied across thousands of trades a day. If the price starts trending up, the market maker continuously adjusts both quotes upward to stay near the new fair value, always ready to buy or sell without taking a large directional bet of its own. This constant two-sided quoting is what keeps the token's spread tight and lets ordinary users trade without moving the price wildly on every order. Without this activity, the same token might trade with a 5% spread between bid and ask, making it expensive and impractical for anyone to buy in and later exit a position without a substantial loss just from the spread itself.
