Ready? Starting this June, we may witness the largest IPO wave in human history.
On May 20, SpaceX publicly filed its S-1 registration statement with the SEC, targeting a Nasdaq listing on June 12. The valuation exceeds $1.8 trillion, with an expected fundraising range of $40–80 billion. On the same day, reports emerged that OpenAI is preparing a confidential S-1 filing, with Goldman Sachs and Morgan Stanley as joint underwriters. The target listing is in September, with the latest funding round valuing the company at $852 billion.
Yesterday, Anthropic officially announced it had submitted its S-1 to the SEC. Just last week, it completed a $65 billion Series H round, rocketing its valuation from $38 billion in 2024 to $965 billion — surpassing OpenAI to become the world’s most valuable private AI company.
Together, these three companies could raise more in IPO proceeds this year than the total raised by all U.S. venture-backed IPOs since 2000. For context, according to Renaissance Capital, the entire U.S. IPO market raised just $28.4 billion in the first five months of this year.
