An unprecedented IPO wave is materializing as three AI giants—OpenAI, Anthropic, and SpaceX—prepare to enter public markets with combined valuations targeting trillions of dollars. On May 22, reports indicated OpenAI is ready to submit its IPO application secretly, potentially listing by September with a target valuation exceeding $1 trillion and plans to raise approximately $60 billion. This figure would more than double the $25.6 billion record set by Saudi Aramco in 2019.

Concurrently, competitor Anthropic is advancing its own listing strategy, projecting revenue to double quarter-over-quarter to $10.9 billion in the second quarter, which could mark its first quarterly operating profit. Deutsche Bank analysis suggests these listings will become a primary macroeconomic variable influencing the direction of risk assets this year.

Despite competing in the same sector, the financial profiles of these entities diverge sharply, presenting a complex dilemma for public market investors. OpenAI reported $5.7 billion in revenue for the first quarter but posted an adjusted operating margin of -122%, indicating a loss of $1.22 for every $1 generated. Projections suggest it will not achieve positive cash flow until 2029 or 2030 at the earliest. In stark contrast, Anthropic generated $4.8 billion in revenue during the same period and is forecast to reach $10.9 billion in the second quarter with an estimated operating profit of $559 million. Data compiled by Woofun AI highlights that while OpenAI burns capital, Anthropic has already demonstrated a path to profitability, challenging the traditional narrative that AI dominance requires prolonged losses.

The sheer scale of these offerings dwarfs historical benchmarks. Deutsche Bank notes that even after inflation adjustments, these IPOs will easily surpass the largest in history. If OpenAI hits its $1 trillion target, it would rank as the 14th largest company globally by market value, trailing only Berkshire Hathaway and surpassing Eli Lilly. While Berkshire Hathaway reported $370 billion in revenue and $67 billion in net profit last year, and Eli Lilly posted $65 billion in sales with $21 billion in profits, OpenAI remains unprofitable with roughly $30 billion in annual revenue and a workforce of only a few thousand. Woofun AI observes that the U.S. stock market, currently valued at approximately $70 trillion, possesses five times the capacity it held at the peak of the Internet bubble, suggesting a robust ability to absorb these new listings compared to the late 1990s.

However, the liquidity impact of a single $60 billion IPO is profound, approaching the total volume raised by all U.S. IPOs in 1999 and 2000 combined. The simultaneous entry of SpaceX, OpenAI, and Anthropic, coupled with NASDAQ's new fast inclusion rules, is creating a siphoning effect on passive capital flows. JPMorgan estimates that if SpaceX reaches a $2 trillion valuation with 50% of shares tradable, passive funds will be compelled to sell approximately $95 billion worth of existing positions in major tech stocks like NVIDIA, Apple, and Microsoft to accommodate the new entries. Todd Sohn of Strategas warns that the extreme imbalance between the typical 5% initial tradable float and trillions in ETF assets will create chaotic index inclusion processes, forcing passive investors to buy at inflated prices.

The upcoming listings serve as a referendum on the broader investment logic of artificial intelligence. OpenAI is projected to generate $13.1 billion in revenue in 2025 but incur a net loss of $14 billion in 2026, alongside a commitment to invest $1.4 trillion in infrastructure by 2033. If S&P Global, FTSE Russell, and NASDAQ adopt fast inclusion protocols, approximately $24 billion to $48 billion in passive funds may be forced to purchase these stocks immediately post-listing. Woofun AI analysis suggests that regardless of active management, ordinary investor portfolios holding index funds will be inadvertently reshaped by these regulatory shifts and massive fund reallocations.

For active investors, the release of S-1 documents will force a binary choice between trusting a profitable model or backing a giant requiring billions more to explore profitability. Anthropic's success stems from explosive demand for corporate programming tools, with 85% of revenue derived from enterprise clients, driving gross margins from 38% to over 70%. CEO Dario Amodei noted that revenue growth has become difficult to manage. Conversely, OpenAI relies on consumer subscriptions for 85% of its revenue, with 55 million paid users amidst 900 million weekly active users, creating high operational costs. Sam Altman aims to pivot toward corporate clients and monetize advertising, projecting $102 billion in ad revenue by 2030, though this timeline is critical given the company's cash burn.

Ultimately, this wave of IPOs functions as a risk transfer mechanism, shifting initial investment exposure from early institutional backers to retail investors and pension funds. Joachim Klement of Panmure Liberum argues that these companies are accelerating listings to capitalize on high sentiment before the hype subsides, allowing early investors to exit while new entrants face the eventual return to financial reality. Citing Alan Greenspan's 1996 warning on irrational exuberance, Klement predicts the AI hype may persist through 2026, but the impossible math of current valuations will likely revert to reality by 2027 or 2028, marking a potential end to the current frenzy.
