Coinbase to become the first crypto firm to join the S&P 500

Coinbase Global (COIN), a cryptocurrency exchange, will become the first and only crypto firm listed in the Standard & Poor’s 500 (S&P 500) index on May 19th. This milestone marks a significant step for the cryptocurrency industry’s integration into mainstream finance. Coinbase will replace Discover Financial Services (DFS), acquired by Capital One.

The S&P 500, tracking 500 large US publicly traded companies, represents a broad measure of the US stock market, boasting a $49.8 trillion aggregate market cap (March 31st). It’s a market-cap-weighted index, prioritizing larger companies like Microsoft, Apple, and Nvidia. Coinbase, likely among the bottom 400 companies, will hold a weighting between 0.01% and 0.2% of the index.

Coinbase’s inclusion will significantly increase demand for its stock. Index funds and ETFs tracking the S&P 500 must purchase COIN shares to accurately reflect the index’s composition. Following the announcement, COIN shares surged 8.8% in after-hours trading, reaching $225.4, adding to a 4% increase on the day, bringing its market cap to $52.8 billion. Coinbase CFO Alesia Haas hailed the inclusion as a “major milestone,” reflecting the industry’s growth and future direction.

This event places Coinbase alongside Tesla (TSLA) and Block Inc. (SQ), prominent Bitcoin holders already in the S&P 500. While MicroStrategy (MSTR), a Bitcoin-stacking firm, was considered last year, its first-quarter 2025 net loss of $4.2 billion disqualifies it for now. S&P 500 entry requires profitability in the last year and quarter, trading on a major US exchange, generating at least half of revenue domestically, and possessing a market cap exceeding $18 billion. MicroStrategy meets the other criteria. Coinbase’s entry signifies a shift; cryptocurrency, once aiming to disrupt traditional finance, is increasingly integrating into established systems.
