What Is Arbitrage? Profiting from Price Differences Across Markets

What Is Arbitrage?

Arbitrage is a trading strategy that involves buying an asset at a lower price in one market and selling it at a higher price in another, aiming to profit from price differences.

It relies on market inefficiencies rather than price direction.


Why Arbitrage Exists

Arbitrage exists because:

  • Markets are fragmented
  • Prices update at different speeds
  • Liquidity varies across platforms
  • Supply and demand differ

Arbitrage helps align prices across markets.


How Arbitrage Works

  1. Price difference is identified
  2. Asset is bought in cheaper market
  3. Asset is transferred or swapped
  4. Asset is sold in higher-priced market
  5. Profit remains after fees

Speed and execution are critical.
