Cryptocurrency markets move fast—prices shift in seconds, new tokens emerge daily, and investor sentiment can flip overnight. In this dynamic environment, reliable, real-time data is essential. That’s where CoinMarketCap (CMC) comes in. As one of the most trusted and widely used cryptocurrency tracking platforms, CoinMarketCap provides users with comprehensive market insights, price data, exchange rankings, and benchmark indices that help investors make informed decisions.
Whether you're a seasoned trader or just starting your crypto journey, understanding how CoinMarketCap works—and why it matters—is key to navigating the digital asset landscape.
Origins of CoinMarketCap
Founded in 2013 by software developer Brandon Chez from his apartment in Queens, New York, CoinMarketCap began as a simple side project aimed at bringing transparency to the chaotic early days of cryptocurrency pricing. At the time, there was no centralized source for tracking crypto values across exchanges. Chez built the site to fill that gap, aggregating price data and calculating market capitalizations for digital assets.
For years, he ran the platform solo. It wasn’t until 2017 that he assembled a core team to manage operations as traffic surged alongside the growing popularity of Bitcoin and altcoins. By 2018, CoinMarketCap had become one of the most visited websites in the world within the crypto space, drawing attention not only from traders but also from major financial publications like The Wall Street Journal.

Core Features and Services
Real-Time Price Tracking
At its heart, CoinMarketCap is a price aggregation platform. It collects data from hundreds of cryptocurrency exchanges globally to provide accurate, up-to-the-minute pricing for thousands of digital assets. This includes:
- Live prices for over 8,000 cryptocurrencies
- Market capitalization calculations
- Trading volume across multiple exchanges
- Supply metrics (circulating, total, and max supply)
This data allows users to compare prices across platforms and identify potential arbitrage opportunities—or discrepancies that could signal manipulation.
Exchange Rankings
CoinMarketCap categorizes exchanges into three main types:
- Spot Exchanges – Platforms where users trade cryptocurrencies directly.
- Derivatives Exchanges – Sites offering futures, options, and other leveraged products.
- Decentralized Exchanges (DEXs) – Non-custodial platforms built on blockchain protocols.
Each exchange is ranked based on verified trading volume, liquidity, and user trust scores—helping traders evaluate platform reliability.
Benchmark Indices
In March 2019, CoinMarketCap launched two major financial indices in partnership with German index provider Solactive AG:
- CMC Crypto 200 Index (CMC200): A market-cap-weighted index tracking the performance of the top 200 cryptocurrencies, representing over 90% of the global crypto market.
- CMC Crypto 200 ex BTC Index (CMC200EX): The same index excluding Bitcoin, allowing investors to assess the broader altcoin market independently.
These indices are available on major financial terminals like Nasdaq, Bloomberg, and Refinitiv, integrating crypto into traditional finance ecosystems.
Impactful Decisions and Market Influence
CoinMarketCap doesn’t just report data—it shapes markets. One notable example occurred on January 8, 2018, when CMC removed several South Korean exchanges from its pricing algorithm due to significant price disparities between Korean and global markets—a phenomenon known as the “Kimchi Premium.”
While intended to improve data accuracy, this change caused a sharp drop in XRP’s market value and triggered broader sell-offs. The incident highlighted CMC’s outsized influence on market sentiment and underscored the importance of transparent methodology in data aggregation.
Acquisition by Binance
In April 2020, global crypto giant Binance acquired CoinMarketCap under undisclosed terms. Reports suggested the deal was valued around $400 million, though this has never been officially confirmed.
Despite the acquisition, CoinMarketCap continues to operate independently, maintaining editorial and operational autonomy. This separation helps preserve its reputation as a neutral data provider—even as concerns about centralization in the crypto ecosystem persist.
API Access and Industry Integration
CoinMarketCap offers a robust public API, first launched in 2016, which enables developers, analysts, and financial platforms to access real-time and historical crypto data. In 2021, it became an official API partner of Coinbase, further cementing its role as a foundational data layer for the industry.
However, data accuracy isn’t always flawless. In late 2021, both Coinbase and Crypto.com temporarily stopped using CMC’s data after glitches led to incorrect price displays—reminding users that even top-tier platforms must constantly refine their systems.
Why CoinMarketCap Matters
With over 350 million monthly page views and more than 445,000 daily active users, CoinMarketCap remains a go-to resource for millions worldwide. Its blend of accessibility, depth, and authority makes it indispensable for:
- Retail investors tracking portfolio performance
- Institutional analysts benchmarking market trends
- Developers building blockchain applications
- Media outlets reporting on crypto news
👉 Access powerful tools to analyze market trends before making your next move.
