Wall Street IPO momentum is starting to fade

Wall Street IPO pipeline starts to lose momentum

The U.S. IPO market has cooled noticeably after a strong start to the year. Several companies, including EG Group, Holtec, Oura and SB Energy, have delayed or paused listing plans, while the expected debuts of Anthropic and OpenAI have also been pushed back. That has disrupted expectations that the autumn would become one of the most active periods for new listings.

According to the Financial Times, the headline numbers for 2026 mask a weaker underlying picture. Total IPO proceeds have reached roughly $147.5 billion, but a significant share has come from a handful of the largest deals. More than 40% of newly listed companies are trading below their offer price, while excluding the biggest transactions, average IPO returns are around -4% compared with roughly +12% for the S&P 500.

Investors push back against aggressive valuations

Pricing is becoming the central issue. Companies are still trying to come to market at valuations shaped during a period of cheaper capital and much stronger risk appetite, while investors are now demanding a larger discount.

Smart-ring maker Oura is a good example. The company postponed its IPO despite strong investor interest. The deal had been expected to involve the sale of 50 million shares at $40–44 each, implying a valuation of around $13.5 billion at the midpoint of the range. Roughly three quarters of the shares on offer were also set to come from existing shareholders, adding further scrutiny around the transaction’s pricing.

A similar pattern is emerging even among companies that are still growing quickly. High interest rates, rising bond yields and a more cautious stance toward richly valued AI assets are pushing investors to focus not only on revenue growth, but also on profitability, cash flow and the amount of capital required to fund further expansion.

AI listings become a test for the broader market

The biggest test for the IPO market may come from future listings by major AI companies. Anthropic and OpenAI remain among the most closely watched potential debuts, but the scale of spending on computing infrastructure and their expected valuations is raising a broader question over how much investors are willing to pay for future growth.

Traders Union previously noted that Oura delayed its Nasdaq IPO amid market volatility despite strong demand, while a potential Anthropic listing remains one of the clearest tests of investor appetite for highly valued technology companies.

That does not mean the IPO window has fully closed. Instead, the market is moving back toward stricter pricing discipline. Companies with strong financials can still attract capital, but stretched valuations and weak post-IPO performance are now much more likely to push investors away from a deal.
