Coinbase shares soared more than 20% on Tuesday and headed for their sharpest rally since the day after President Donald Trump’s election victory following the crypto exchange’s inclusion in the S&P 500.

S&P Global said in a release late Monday that Coinbase is replacing Discover Financial Services, which is in the process of being acquired by Capital One Financial. The change will take effect before trading on Monday.

Stocks added to the S&P 500 often rise in value because funds that track the benchmark will add it to their portfolios. For Coinbase, it’s the latest sharp move in what’s been a volatile few months since Trump was elected to return to the White House.

Coinbase shares rocketed 31% on Nov. 6, the day after the election, on optimism that the incoming administration would adopt more crypto-friendly policies following a challenging and litigious four years during President Joe Biden’s term in office.

The company and CEO Brian Armstrong were key financial supporters in the 2024 campaign, backing pro-crypto candidates up and down the ticket. Coinbase was one of the top corporate donors, giving more than $75 million to a PAC called Fairshake and its affiliates. Armstrong personally contributed more than $1.3 million to a mix of candidates.

While the start of the Trump term has been mostly favorable to the crypto industry, through deregulation and an executive order to establish a strategic bitcoin reserve, legislation has thus far stalled. That’s due in part to concerns surrounding Trump’s personal efforts to profit from crypto through a meme coin and other family initiatives.

Coinbase has been on a roller coaster as well, plummeting 26% in February and 20% in March as Trump’s tariff announcements roiled markets and pushed investors out of risk. With Tuesday’s rally, the stock is now up about 2% for the year.

Since going public through a direct listing in 2021, Coinbase has become a bigger part of the U.S. financial system, with bitcoin soaring in value and large institutions gaining regulatory approval to create spot bitcoin exchange-traded funds.

Bitcoin spiked last week, topping $100,000 and nearing its record price reached in January. The crypto currency surpassed $104,000 on Tuesday.

To join the S&P 500, a company must have reported a profit in its latest quarter and have cumulative profit over the four most recent quarters.

Coinbase last week reported net income of $65.6 million, or 24 cents a share, down from $1.18 billion, or $4.40 a share a year earlier, after accounting for the fair value of its crypto investments. Revenue rose 24% to $2.03 billion from $1.64 billion a year ago.

The company last week also announced plans to buy Dubai-based Deribit, a major crypto derivatives exchange for $2.9 billion. The deal, which is the largest in the crypto industry to date, will help Coinbase broaden its footprint outside the U.S.
