US IPO Performance Lags S&P 500 in 2025 as Crypto, AI Deals Sink

US initial public offerings delivered underwhelming results in 2025 as equity-market volatility and increasing scrutiny around themes such as crypto and artificial intelligence hit some of the year’s most high-profile listings.

Shares of companies that debuted in 2025, excluding closed-end funds and blank-check vehicles, climbed 13.9% on a weighted average basis, under-performing the S&P 500 Index’s 16% gain.

“2025 was a distinctly mixed year for IPOs. The market reopened, but it did so selectively,” said Mike Bellin, PwC’s US IPO leader. Investors prioritized quality over momentum, and the bar for going public — especially for earlier-stage tech and consumer companies — rose meaningfully, he said.

Deals Under $1 Billion

Medium-sized offerings delivered relatively weaker performance than larger ones, with shares of US deals between $500 million and $1 billion increasing a weighted average of just 5.6%, versus 20% for $1 billion-plus transactions, the data show.

Data center campus developer Fermi Inc. tapped into enthusiasm over artificial intelligence to raise $785 million in a listing, even without any revenue or confirmed tenants. Its shares were already well below the IPO price when the company announced Dec. 12 that its first investment-grade tenant had canceled the deal. The stock is now down 58% from the IPO.

Navan Inc. sank 35% since the AI corporate-travel and expense platform and some of its backers raised $923 million in its October debut, as prospective investors questioned the unprofitable firm’s near-term margin profile. Despite almost universally bullish analyst coverage, which cited the company’s AI-driven tools and long-term growth potential, its shares have yet to close above the IPO price.
