The total crypto market cap stood near $2.3 trillion in July 2026, down 47% from the October 2025 all-time high of approximately $4.27 trillion. How Crypto Market Cap is CalculatedThe formula is straightforward: current price multiplied by circulating supply equals market capitalization. A Layer 1 blockchain with $10 billion in market cap and $5 billion in TVL differs from a meme token with $10 billion in market cap and zero TVL. How is the crypto market cap different from the stock market cap? The formula is identical, but crypto market caps use circulating token supply while stock market caps use outstanding shares, and crypto trades around the clock.
