For years, the S&P 500 has been the most important benchmark for mainstream U.S. investing. But in a move that is turning heads on Wall Street and beyond, the index now includes Coinbase Global, Inc. (COIN) as its first crypto-native member.
If you invest in an S&P 500 index fund, you now have a stake in the world of digital assets, whether you planned to or not. Our analysis below helps you understand what this means for your portfolio.
Key Takeaways
- Coinbase, the largest U.S. crypto exchange, is the first crypto-native company to join the S&P 500.
- The move signals growing mainstream acceptance of crypto but also introduces new volatility and regulatory risks to the index.
- Coinbase represents a very small percentage (about 0.11%) of the S&P 500’s total value.
Crypto’s Big Leap Into the Mainstream
Cryptocurrencies and their exchanges have long been viewed as speculative outliers. That changed in May 2025, when Coinbase officially joined the S&P 500, replacing Discover Financial Services, which merged with Capital One Financial Corporation (COF).
The move marks the first time a company rooted in blockchain finance sits alongside giants like Apple Inc. (AAPL) and JPMorgan Chase & Co. (JPM). “Coinbase joining the S&P 500 means crypto’s here to stay,” said Coinbase CEO Brian Armstrong.
How Coinbase’s Inclusion Changes the Game
Coinbase’s inclusion in the index caused shares to jump and could lead to billions in buying from both passive and active funds, based on some estimates.4 That will bolster its liquidity and help stabilize its share price over time, while also serving as a vote of confidence for the crypto industry.
