PwC: SpaceX Leads US IPO Boom, First-Half Fundraising Exceeds $114 Billion
According to PwC data, traditional US IPO market raised approximately $114.1 billion in the first half of 2026, more than seven times the amount in the same period last year, marking the strongest level since 2021. SpaceX contributed a significant share with its historic $75 billion IPO, the largest ever, but its stock price fell 33% after listing, drawing attention. Besides SpaceX, AI-related companies such as Cerebras Systems also performed strongly, with SPAC issuance accelerating in tandem. Looking ahead to the second half of the year, potential listings by OpenAI and Anthropic could spark another surge.
A recent analysis by PwC shows that in the first half of 2026, U.S. companies raised approximately$114.1 billionthrough traditional initial public offerings (IPOs), a more than sevenfold increase year-over-year, marking the highest level of IPO market activity since 2021.
According to PwC data, as of June 30, a total of65traditional IPOs were completed, nearly double the34in the first half of 2025. Traditional IPOs exclude special purpose acquisition company (SPAC) offerings. This surge was partly driven by SpaceX's record-breaking public listing, which accounted for a significant share of total proceeds.
"The window is fully open, and companies that are prepared for it are being rewarded," said Mike Bellin, PwC's U.S. IPO leader, in an interview. Despite companies still facing a volatile business environment, the IPO market is rebounding strongly.
Macro backdrop: Economic optimism dips slightly, inflation concerns resurface
A recent report from Duke University's Fuqua School of Business and the Federal Reserve Banks of Richmond and Atlanta shows that due to energy price shocks bringing inflation back to the top of financial executives' concerns, CFO optimism about the U.S. economy declined slightly in the second quarter. Financial executives' expectations for real GDP growth over the next four quarters were2.1%revised down to1.8%. However, CFOs are more optimistic about their own companies; since the last survey, financial leaders have raised their 2026 unit cost and price growth forecasts by1.1 percentage points。
PwC stated that the macroeconomic backdrop is "supportive, despite some notable challenges." The report said: "We continue to believe the IPO market is open for companies with the right scale, durable growth, a credible path to profitability, and the operational maturity of a public company from day one. Even so, current conditions suggest the window can open and close quickly. Companies that are well-prepared, flexible, and disciplined on valuation will be in the best position to execute."
Second-quarter momentum continues, marking a 'true inflection point'
PwC noted that unlike previous recovery cycles where strong starts often stalled, second-quarter IPO activity "built significantly on the first quarter." Bellin called the first half a "true inflection point" for the IPO market, driven by economic resilience, strong investor interest in high-growth story companies, and a backlog of issuers delayed by the U.S. Securities and Exchange Commission's (SEC) 43-day shutdown in late 2025.
"When you see companies with strong KPIs, strong revenue growth, a clear business story, durable recurring revenue, profitability or a credible path to it, and public-company readiness—they have indeed been waiting for the right time," Bellin said.
SpaceX's IPO in particular is seen as a "defining event," highlighting deep investor demand for "scaled, category-defining growth companies" and continued interest in AI infrastructure.
SpaceX listing details and subsequent volatility
SpaceX completed the largest IPO in history onJune 12, raising$75 billionby selling over500 million sharesat an offering price of$135 per share, closing its first day around$161. According to CNBC reports at the time, its stock rose significantly above the offering price. However, according to a Reuters article on Thursday, the stock has fallen33%since its record close, an ominous signal for the business. A Reuters analysis of 50 high-profile U.S. IPOs since 2010 found that companies whose stocks fell below their offering price within two months of listing tended to perform worse afterward than those that did not, though most still posted gains.
Beyond SpaceX, market recovery is broad-based
PwC said that excluding SpaceX, first-half 2026 IPO proceeds were still nearly three times those of the same period last year, indicating the recovery is not driven solely by a single star listing. Other large second-quarter IPOs included AI computing infrastructure company Cerebras Systems, which priced more than 50% above its initial filing range.
SPAC issuance also accelerated in the first half. As of June 30, a total of118SPAC IPOs raised approximately$21 billion, compared with66。
AI-driven 'two-speed market,' strong second-half outlook
The analysis points to AI as a major driver of investor interest. Bellin said companies with credible AI narratives—whether AI-focused or those using AI to strengthen their competitive position—are attracting more investor attention, while those unable to clearly explain AI's impact on their growth strategy face tougher scrutiny. "The AI dynamic is creating a true two-speed market," he said, adding that companies need to back their AI stories with credible metrics and KPIs.
Looking ahead, PwC expects continued strong issuance across sectors in the second half of 2026. The pipeline includes AI market leaders OpenAI and Anthropic, both of which have confidentially filed for IPOs. The report said: "If market conditions remain supportive, these deals could rank among the largest tech IPOs in history and account for a significant share of second-half 2026 issuance."
