Simple Definition

When a firm fills your order from its own inventory instead of sending it to an exchange.

Why It Matters

Internalization means a wholesaler takes the other side of your trade directly, filling it from its own book rather than matching you on a public exchange. It can be fast and often comes with a bit of price improvement, which is part of why it's common for retail orders. The flip side is that the order never reaches a public venue, so it doesn't add to visible market activity - one reason critics scrutinize how much retail volume is internalized.

Key Points

  • The firm fills your order from its own inventory
  • Common for retail orders, often with price improvement
  • The trade never reaches a public exchange
