Wall Street bankers are entering the remainder of 2026 with notable optimism after an unprecedented wave of share offerings in the first half of the year. According to Bloomberg’s compilation, the value of U.S. initial public offerings (IPOs) and secondary share sales reached $251 billion through June 26, excluding hedge funds and other investment vehicles.
Major transactions and the role of AI
A standout deal was SpaceX’s $86.2 billion market debut, the largest IPO on record. Separately, Alphabet — the parent company of Google — completed an $85 billion capital raise that, while not a public listing, is among the largest transactions tied to the sector. Goldman Sachs analysts say issuance volumes were growing rapidly even without these outsized deals, and they point to optimism around artificial intelligence as the primary driver.
AI infrastructure — meaning data centers and related development — requires substantial capital, and sustained share prices combined with strong investor demand have supported large fundraising transactions.
Market size and bankers’ expectations
Bloomberg’s figures show eleven individual transactions exceeded $1 billion so far this year. JPMorgan analysts expect another dozen or so similarly sized deals in the second half of the year. Attention is also turning to private equity-backed companies, which had been somewhat sidelined among the largest public listings but are now being considered for market entry.
Notable potential transactions include Anthropic’s possible mega-deal that could be scheduled for October. Csquare, a data-center specialist backed by Brookfield, is reported to be preparing to launch an official sales process in the coming days. Other prospective candidates include Inspire Brands, owned by Roark, and Jersey Mike’s, supported by Blackstone.
Performance and risks
The weighted average return of U.S. companies that went public this year is approaching 16 percent, nearly double the performance of the S&P 500 year-to-date. However, not all activity is strictly AI-related: chipmaker Cerebras completed a $6.38 billion offering in May, though its shares have since drifted back toward the offering price.
Morgan Stanley projects a very busy third quarter, while market volatility could rise in the fourth quarter due to the November midterm elections, meaning many deals are likely to concentrate in the summer months.
