Market Maker
A market maker is a trader or firm that continuously quotes both a buy price and a sell price for an asset, so other people can trade at any time. By doing this it provides liquidity to the market.
What a market maker actually does
On an exchange, every trade needs two sides. If you want to sell a coin right now, someone must be willing to buy it right now. A market maker solves this by keeping standing orders on both sides of the order book: a bid (the price it will pay) and an ask (the price it will sell at).
The gap between those two prices is the spread. The market maker aims to buy at the bid and sell at the ask many times a day, earning small amounts on each round trip rather than betting on where the price goes.
An example
Say a market maker quotes a token at 9.98 to buy and 10.02 to sell. One trader sells 1,000 tokens to it at 9.98, and a few minutes later another trader buys 1,000 tokens from it at 10.02. If the price stayed put, the market maker earned about 40 dollars, minus fees. If the price dropped to 9.50 before it could sell, it would lose money on the tokens it was holding. Managing that inventory risk is the core of the job.
Who the market makers are in crypto
On centralized exchanges, market makers are usually specialised trading firms running automated software. Exchanges often reward them with lower or even negative maker fees, because resting orders make the book deeper. Token projects also sign deals with market-making firms to keep their coin tradable after a listing.
In decentralized finance, much of this role is played by automated market makers (AMMs): smart contracts that price trades with a formula, funded by ordinary users who deposit tokens into liquidity pools.
Why it matters and what can go wrong
Good market making means tighter spreads, less slippage and fairer prices for everyone. When market makers pull back, often during sudden crashes, spreads widen and order books thin out, so the same order moves the price much further.
Market makers can also be part of the problem. Some arrangements between small token projects and market-making firms have been linked to wash trading, meaning fake volume, or to large sell-offs right after launch. A busy-looking market is not proof of real demand.

Frequently asked questions
Do market makers manipulate prices?
Honest market making does not; it earns the spread by being available to trade. Manipulation such as spoofing or wash trading is a separate practice, and it is illegal in regulated markets.
How do market makers make money?
Mainly from the bid-ask spread and from exchange fee rebates, repeated over a very large number of trades. They lose money when prices move sharply against the inventory they hold.
Is an automated market maker the same thing?
It fills the same role, but instead of a firm quoting prices, a smart contract sets the price from the ratio of tokens in a pool. Anyone can supply the pool's liquidity.
