Market capitalization, or market cap for short, is just a way to figure out how much a company is worth in the stock market. It’s the total value of all a company’s shares that are currently out there. Investors often use market cap to compare the size of different companies.
This number isn’t fixed—it changes all the time depending on what investors think the company is worth. Financial experts often study things like sales and revenue to decide if a company’s market cap makes sense, or if it’s being valued too high or too low.
💡 How Do You Calculate Market Cap?
It’s actually pretty simple:
Market Cap = Current Share Price × Total Number of Shares Outstanding
For example, if a company has 20 million shares and each one sells for $100, its market cap would be $2 billion.
But let’s say another company’s stock costs $1,000, but it only has 10,000 shares available. Its market cap would be just $10 million. So price alone doesn’t tell the full story—market cap gives you a clearer picture of a company’s overall value.

📊 What Market Cap Tells You About a Company’s Size
Market cap is also a way to group companies by size:
- Large-Cap: These companies are worth $10 billion or more. They’re usually big, well-known brands like Apple, Microsoft, or Google’s parent company Alphabet. They tend to grow steadily and often pay dividends.
- Mid-Cap: Valued between $2 billion and $10 billion, these companies are in the growth phase. They’re more established than small businesses but still have room to expand. They carry a bit more risk than large-cap companies.
- Small-Cap: These are worth between $250 million and $2 billion. They’re often newer or niche companies. They can grow fast—but they’re also riskier and more likely to have big price swings.
- Micro-Cap: Companies worth less than $250 million fall into this category. They’re very small and come with higher risk.
🪙 Market Cap and Cryptocurrencies
When it comes to cryptocurrencies like Bitcoin, the market cap is calculated a little differently. That’s because new coins can be added over time.
So analysts often look at both:
- Market Cap = Current Price × Number of Coins in Circulation
- Diluted Market Cap = Current Price × Total Number of Coins That Could Ever Exist
For example:
If Bitcoin is trading at $24,000 and 19.8 million coins have already been mined:
- Market Cap = $24,000 × 19.8 million = $475.2 billion
- Diluted Market Cap = $24,000 × 21 million (max supply) = $504 billion
This helps give a better picture of what could happen if all coins or tokens are released in the future.

🚫 Common Myths About Market Cap
A lot of people think market cap tells you exactly what a company is worth—but that’s not quite true.
It only reflects what investors are willing to pay for the stock right now. Sometimes stocks are overpriced, and other times they’re a bargain. That’s why it’s important to also look at the company’s financials, not just the market cap.
Also, market cap doesn’t tell you how much it would cost to buy the whole company. For that, analysts use something called enterprise value, which includes things like debt and cash on hand.
