US IPO Stocks Jump Over 50% in 2025 as Investor Appetite for Risk Grows

Roaring returns for US IPOs are driving fresh optimism that activity will pick up steam later this year and into 2026, even as worries over geopolitics and President Donald Trump’s tariffs hang over the market.

Led by triple-digit-percent increases for Circle Internet Group Inc. and CoreWeave Inc. — two of the year’s five largest initial public offerings on US exchanges — this year’s class of debutantes are trading up by a weighted average of about 53%, data compiled by Bloomberg show. That’s left investors hungry for more, particularly in a year where the S&P 500 Index has struggled to remain in the black.

“We’ve been positively surprised by the way the market has handled the tariff headlines, and how investors have thought about that potential risk factor,” according to Keith Canton, JPMorgan Chase & Co.’s co-head of Americas equity capital markets.

That resilience could draw out some of the companies that had been planning to go before Trump’s tariffs briefly derailed activity. The US IPO calendar into summer is sparse, but the second half of 2025 has more promise.

A handful of $1 billion-plus IPOs are likely before the end of the year, most of which will come after Labor Day, said Canton.
