How does market making work? Market making works by continuously placing both buy (bid) and sell (ask) orders in a financial market to provide liquidity. Market makers profit from the difference between these prices (the spread) while managing risk through high-frequency adjustments, inventory control, and advanced trading strategies—making them essential to smooth and efficient markets.

What is Market Making?

Before diving deeper into how does market making work, let’s simplify the concept.

Market making is a trading activity where firms or individuals continuously quote both buying and selling prices for an asset.

👉 Their job is simple:

• Always be ready to buy
• Always be ready to sell

This ensures there’s always liquidity in the market.

How Does Market Maker Work in Real Markets?

Understanding how does market maker work requires looking at the mechanics.

Basic Process:

1. Market maker sets a bid price (buy price)
2. Sets an ask price (sell price)
3. Traders interact with these prices
4. Market maker earns the spread

Simple Market Maker Example

Let’s take a quick market maker example:

• Bid price: ₹100
• Ask price: ₹101

👉 If a trader sells at ₹100 and another buys at ₹101:

Profit = ₹1 per share

This small margin, when repeated thousands of times, becomes highly profitable.
