Crypto and Blockchain Stocks: 9 Biggest Companies
From Bitcoin miners to exchange giants and infrastructure builders, these companies are the ones to watch in crypto, digital assets and blockchain in 2026.
The list below breaks down each business model, the key developments shaping it this year and why they matter for investors following the sector.
US crypto and blockchain stocks
Below are five of the largest US crypto and blockchain technology stocks by market cap on the NASDAQ and NYSE for investors to consider. Market cap figures were current as of June 29, 2026.
Market cap: US$46.44 billion
Block is a fintech company whose core products are Square and Cash App, with BTC treated as a product layer across payments, self-custody and merchant tools.
In 2026, Block began a large restructuring effort to make the business leaner while continuing to expand BTC payments and conversion features for sellers. The company said it would cut more than 40 percent of its workforce, take roughly US$450 million to US$500 million in charges, and reorganize around smaller teams focused on Square, Cash App and the BTC ecosystem.
Market cap: US$32.48 billion
Strategy, formerly MicroStrategy, is a BTC treasury company that uses equity and other capital-market tools to buy and hold BTC rather than building a broad operating crypto business.
Strategy often functions as a sentiment proxy for Bitcoin, because its stock and news flow are tightly tied to BTC price, and its buying pace is watched as a signal of institutional conviction.
In June 2026, the company disclosed its first standalone Bitcoin sale in years, offloading 32 BTC for about US$2.5 million at an average price of US$77,135. The company said the proceeds were intended to help fund preferred-stock distributions.
Later on, Strategy announced a new Digital Credit Capital Framework, authorizing up to US$2 billion in buybacks and up to US$1.25 billion in BTC sales. At the same time, the company raised the dividend on its STRC preferred shares to 12 percent and said its USD reserve stood at about US$2.55 billion.
3. Coinbase Global (NASDAQ:COIN)
Market cap: US$1.26 billion
Coinbase is the biggest US crypto exchange, with revenue from trading, stablecoins, staking and its Base network. In recent years, the company has been pushing deeper into payments and on chain infrastructure in an effort to own the infrastructure layer for crypto, effectively becoming an “everything exchange.”
The company is also able to operate in the EU’s 27 member states, which enacted its Markets in Crypto-Assets Regulation (MiCA) law on July 1, as Coinbase secured a MiCA license in Luxembourg.
