Coinbase Global, Inc. is an American cryptocurrency exchange platform founded in 2012 by Brian Armstrong and Fred Ehrsam. It is the largest cryptocurrency exchange in the United States and the world's largest Bitcoin custodian, serving over 108 million customers. The company became the first major cryptocurrency exchange to go public in the United States when it listed on NASDAQ via direct listing in April 2021, and in May 2025 became the first cryptocurrency-native company admitted to the S&P 500 index.
History and Founding
Brian Armstrong, a former Airbnb software engineer, founded Coinbase in June 2012 after becoming captivated by the Bitcoin whitepaper. He enrolled in the Y Combinator startup incubator program, receiving $150,000 in initial funding. Fred Ehrsam, a former Goldman Sachs trader, joined as co-founder after encountering Armstrong's posts on Reddit about building a simple, compliant Bitcoin exchange.
Coinbase launched its core service -- buying and selling bitcoin through bank transfers -- in October 2012. The platform's emphasis on regulatory compliance and user-friendliness distinguished it from existing exchanges, which at the time were largely unregulated and technically intimidating for mainstream users. The company grew rapidly during Bitcoin's 2013 price surge and raised a $25 million Series B round from Andreessen Horowitz that year, one of the largest venture capital investments in a Bitcoin company to date.
Growth and Public Listing
Coinbase expanded from a simple Bitcoin brokerage into a full-featured exchange platform, eventually supporting hundreds of cryptocurrency assets. The company raised over $500 million in venture capital across multiple funding rounds prior to going public.
On April 14, 2021, Coinbase went public on the NASDAQ Global Select Market via a direct listing under the ticker symbol COIN. The stock opened at $381 per share, giving the company a fully diluted valuation exceeding $100 billion -- making it the largest direct listing in history at the time and a landmark moment for the cryptocurrency industry. The listing was widely interpreted as a validation of the broader digital asset ecosystem by traditional financial markets.
In May 2025, Coinbase joined the S&P 500 index, becoming the first pure cryptocurrency company to be included in the benchmark that tracks the 500 largest publicly traded U.S. companies.
Bitcoin and Institutional Custody
Coinbase has played a foundational role in bridging Bitcoin with traditional finance through its institutional custody services. Coinbase Custody Trust Company, a qualified custodian regulated by the New York State Department of Financial Services, provides secure storage for institutional investors, funds, and corporations.
When the U.S. Securities and Exchange Commission approved spot Bitcoin ETFs in January 2024, Coinbase became the primary custodian for the majority of these products, including BlackRock's iShares Bitcoin Trust (IBIT), the largest spot Bitcoin ETF by assets under management. By mid-2025, Coinbase held over $245 billion in assets under custody and was estimated to secure more than 12% of all bitcoin in existence, making it the single largest custodian of bitcoin globally.
Regulatory Battles
Coinbase has been at the center of the U.S. cryptocurrency regulatory debate. In June 2023, the SEC filed suit against Coinbase, alleging it operated as an unregistered securities exchange, broker, and clearing agency. Coinbase vigorously contested the charges, arguing that existing securities regulations were not designed for digital assets and that the SEC had failed to provide clear rules for the industry. In February 2025, under the new presidential administration, the SEC dropped the case with prejudice, preventing re-filing of the charges -- a turning point in U.S. cryptocurrency regulation.
Throughout the regulatory battle, Coinbase positioned itself as an advocate for clearer crypto legislation, lobbying Congress and launching the "Stand with Crypto" political advocacy campaign.
Significance
Coinbase has served as the primary on-ramp to Bitcoin and cryptocurrency for millions of Americans and has been instrumental in bringing institutional capital into the Bitcoin ecosystem. Its role as custodian for the spot Bitcoin ETFs places it at the infrastructure layer of traditional finance's engagement with Bitcoin. The company's S&P 500 inclusion marked a symbolic milestone: a cryptocurrency-native company being treated as a core component of the American economy.
