Market Cap: What It Actually Measures
What You'll Learn
- How market capitalization is actually calculated
- Why price alone doesn't tell you an asset's overall size
- A common mistake in comparing two assets by price alone
The Big Idea
Welcome to Fundamental & Market Analysis. Let me start by teaching you market capitalization, almost always shortened to market cap. It is an asset's price multiplied by its circulating supply — a measure of an asset's total size, not just how expensive one unit of it happens to be.
Let's Break It Down
The formula is simple: price per unit, multiplied by the number of units in circulation. Two assets can have very different individual prices while having a similar overall market cap, or the same price while having wildly different market caps, depending entirely on how many units of each actually exist.
This matters because price alone is a misleading way to judge an asset's overall size. Imagine an asset priced at $1, with 10 billion units in circulation. Its market cap is $10 billion. Now imagine an asset priced at $100, with only 10 million units in circulation. Its market cap is $1 billion. The second one is actually far smaller overall, despite its much higher individual unit price.
Market cap is generally used as a rough proxy for an asset's overall size and significance relative to others, similar to how it is used for comparing companies by size. As later lessons in this module will show you, it is a starting point for context, not a complete picture on its own.
Real Example
Imagine comparing two lemonade stands by the price of a single cup, without asking how many cups each one has sold overall. That would be misleading. One might charge $1 a cup but have served ten thousand customers, while the other charges $5 a cup but has only served a hundred. Market cap is the equivalent of looking at total business size, not just the price of one unit.
Why It Matters
Market cap is one of the most frequently cited numbers in crypto, and I want you to understand that it is price times supply, not price alone. This prevents a very common, very basic misunderstanding when comparing two different assets.
Common Mistake
Please do not assume a lower unit price means an asset is "cheaper" or has more room to grow than a higher-priced one. Unit price alone says nothing about an asset's overall size. Only market cap, which accounts for supply as well, gives that comparison any real meaning.

How is market capitalization calculated?
Key Takeaways
- Market cap equals price per unit multiplied by circulating supply.
- Unit price alone doesn't indicate an asset's overall size — two assets can have very different prices but similar market caps, or vice versa.
- Market cap is a useful starting point for comparing overall size, but not a complete picture on its own.
