U.S. IPO Fundraising Hits Record $225B in First Half of 2026, SpaceX Completes Largest IPO

According to Goldman Sachs, U.S. initial public offerings (IPO) raised a record $225 billion in the first half of 2026, surpassing historical highs. Market experts discussed whether the IPO boom signals late-cycle economic indicators and potential market bubble risks.

According to the bank's analysis, current IPO activity meets at least one of four bubble warning signs: aggressive corporate stock issuance. Investors and analysts remain divided on implications; some highlight that recent IPOs underperformed the broader market since 2019, while others note the U.S. stock market, valued at approximately $75 trillion, has sufficient capacity to absorb the new supply. SpaceX completed the largest IPO in history in June; its stock price has since fallen below the offering price. The S&P 500 has gained 9.5% year-to-date.
