The postponement of two initial public offerings—Bamboo Insurance Services and Holtec Nuclear—within less than a week points to a deterioration in the U.S. IPO market, despite record highs in U.S. stock indices. Freedom analyst Vladimir Chernov expects that in the coming months, low- and mid-quality offerings will be postponed, and new issuers will have to lower their business valuations.
Bamboo and Holtec postponed their stock market debut
Bamboo Insurance Services operates in the U.S. homeowners insurance market. The company planned to sell 35 million shares at $18–20 per share and raise up to $700 million at a valuation of up to $3.24 billion. The offering was to consist solely of shares from CVC Capital Partners and White Mountains. However, the company postponed its market debut, citing market conditions. prnewswire.com
A few days earlier, Holtec Nuclear, a manufacturer of nuclear power equipment and a developer of small modular reactors, withdrew from its IPO. The company had hoped to raise about $900 million. Previously, Freedom explained the reasons behind Holtec’s decision.
September turned out to be weaker than expected for the U.S. IPO market. Activity was affected by rising oil prices, persistent inflation, and a Federal Reserve rate hike, which increased the cost of capital. Due to volatility, investors became more demanding about new issuers’ valuations, and companies preferred to postpone offerings. After Labor Day, when the number of IPOs typically rises, only three companies went public. In total, out of more than 20 issuers that filed since early July and worked with at least one major Wall Street bank, nine completed an offering .
September also came in weaker than expected for the U.S. offering market. After Labor Day, when activity usually increases, only three companies went public. Of more than 20 issuers that filed since early July and worked with at least one major Wall Street bank, nine completed an offering.
Index records do not guarantee IPO success
The postponements occurred against the backdrop of strong performance in the U.S. market. At the close on September 21, the Nasdaq Composite rose 2.26% to a record 27,122.09 points, while the S&P 500 gained 1.49% to 7,764.7 points, stopping about 0.4% short of its all-time high. However, Chernov emphasizes that a rally in already-traded stocks does not mean equally favorable conditions for new issuers.
Investors have become more demanding with respect to companies’ financial metrics, growth prospects, and stated business valuations. Issuers with high debt loads, unstable revenue, or distant timelines to profitability risk facing weak demand.
Competition for capital is being intensified by the largest offerings. In 2026, companies raised $161.4 billion in the U.S. IPO market—the highest amount since 2021. However, a significant share of that total was driven by large deals, including the offerings of SpaceX and SK Hynix.
Rate hike increased the cost of capital
Additional pressure on the market came from the Federal Reserve’s September rate increase to 3.75–4%. More expensive borrowing increases companies’ debt-servicing costs and at the same time reduces the current valuation of their future cash flows.
The prospect of another rate hike before year-end may keep investors cautious. Particularly vulnerable are companies that will need additional funds after going public to finance major projects.
According to Chernov, conditions in the U.S. IPO market will remain unfavorable in the coming months. The most resilient and fast-growing companies will be able to find demand, while the rest will have to lower the offering price or postpone their market debut.
The IPO market is becoming more selective
Back in the summer, Freedom analysts noted that the U.S. IPO market was gradually recovering, and that investors were most interested in companies in artificial intelligence, digital infrastructure, energy, and high technology.
However, the Fed rate and rising requirements for new issuers changed the picture. Against this backdrop, Freedom spoke about the U.S. market shifting to targeted investments: investors began to assess companies’ financial performance more carefully and were less willing to buy shares solely on expectations of rapid growth.
The first notable signal was the decision by Holtec Nuclear, which was preparing to raise up to $825 million in an IPO, but then suspended the offering. Freedom linked this decision to growing investor caution toward capital-intensive energy projects.
The postponement of Bamboo Insurance Services’ IPO showed that the difficulties are no longer affecting only companies tied to energy and artificial intelligence. If high rates persist, the pressure may spread to other industries as well.
