What Is a Crypto Exchange Market Maker? An Introduction to Liquidity Provision and Bid-Ask Spreads (2026)

Market makers are professional participants who continuously place both buy and sell orders on the order book, providing immediate counterparties for trades. They mainly earn income from the bid-ask spread, do not predict price direction, and instead provide continuous two-sided quotes. On cryptocurrency exchanges, the presence of market makers directly determines order book depth and execution efficiency.

#What Is a Cryptocurrency Exchange Market Maker?

A market maker is a professional trader who acts as both buyer and seller. Unlike ordinary traders, who only trade when prices are favorable, market makers continuously place two-sided orders to provide liquidity to the market. They typically use algorithmic trading systems to adjust quotes within milliseconds in response to market changes.

#How Do Market Makers Differ from Regular Traders?

Regular traders aim to buy low and sell high, waiting for the right price before acting. Market makers place both buy and sell orders at the same time, ready to trade at any moment. Think of them like a market stall owner who posts both a "buying price" and a "selling price" and earns the difference in between. Market makers do not predict direction; they simply provide continuous quotes.

#How Do Market Makers Provide Liquidity?

Market makers quote both a bid and an ask price for the same asset at the same time, ensuring other traders always have a counterparty. Order book depth increases, trades execute faster, and slippage decreases. The thicker the buy and sell side of the order book, the less impact large orders have on price—which is why liquid markets are more attractive to traders. To learn about slippage, see What Is Slippage?. It’s like supermarket shelves that are always stocked, so customers don’t have to wait.

#How Is the Bid-Ask Spread Formed?

The bid price is always lower than the ask price. This difference is the bid-ask spread. The spread is the main source of income for market makers and compensation for the inventory risk and operational costs they bear. The size of the spread is affected by market volatility: the higher the volatility, the wider the spread tends to be; the narrower the spread, the lower the trading cost. Besides volatility, trading volume, inventory levels, and competition also affect the spread. For example, major trading pairs such as BTC/USDT usually have spreads of only a few basis points, while illiquid altcoins may have spreads exceeding 1%. It’s like currency exchange—the buy and sell rates are different.

#Why Are Market Makers Important to Crypto Exchanges?

Market makers improve market efficiency and reduce trading costs. Without market makers, markets can become illiquid, trading becomes difficult, and price discovery becomes more unstable. Exchanges usually offer fee discounts or rebates to market makers to incentivize them to keep providing liquidity. This cooperation benefits all three parties: exchanges, market makers, and regular traders. That is also why many exchanges have dedicated market maker programs.

#What Risks or Common Misconceptions Do Market Makers Have?

Market makers are not guaranteed to profit. Price fluctuations while holding assets lead to inventory risk; trading with better-informed traders leads to adverse selection risk. In extreme market conditions, market makers may face large losses. During sharp market moves, market maker losses can quickly expand, so they need strict risk management mechanisms.

#FAQ

Q: How do market makers differ from regular traders? A: Regular traders wait for the right price before buying or selling; market makers place both buy and sell orders at the same time, always providing opportunities to trade and earning the bid-ask spread.

Q: How do market makers make money? A: Market makers mainly profit from the bid-ask spread. They buy at the lower bid price and sell at the higher ask price, earning the difference in between. Spread income compensates them for the inventory risk and operational costs they bear.

Q: Why does the bid-ask spread exist? A: The bid-ask spread compensates market makers for bearing inventory risk and operational costs. The spread tends to be wider during times of high volatility. Assets with low trading volume and high inventory risk also have wider spreads.

Q: Do market makers always make money? A: No. Market makers are not guaranteed to profit. Inventory risk and adverse selection risk are two major threats. Inventory risk refers to losses from price fluctuations while holding assets; adverse selection risk is losing money by trading with better-informed counterparties. For example, in extreme market conditions, market makers may be forced to close positions at unfavorable prices and suffer large losses.

Q: Are market makers and automated market makers (AMMs) the same thing? A: No. Traditional market makers are professional teams or institutions that place orders manually or algorithmically and profit from the bid-ask spread through two-sided quotes. Automated market makers (AMMs) are smart contracts on decentralized exchanges (DEXs), where liquidity is provided by liquidity pools and prices are determined by mathematical formulas such as constant product. The former is common on centralized exchanges, while the latter is common in DeFi.
