The Total Addressable Market Trap

Market size tells you how much money exists in a category. It does not tell you how much of it is still available to you.

Open a research tool and the biggest number on the screen is the size of the market. It is also the number least likely to describe anything you can win.

This episode works through why a large category is usually a crowded one, the difference between the whole market and the share a seller can realistically take and then hold, why the biggest categories so often carry the thinnest margins, and why a small market defended properly tends to compound faster than a large one entered badly.

The distinction

The Total Addressable Market tells you how much money exists. It does not tell you how much of it is still available. Those are two different numbers, and only one of them is yours to go and win.
