OpenAI, Anthropic, SpaceX IPO Crunch

OpenAI just told CNBC it plans to set aside part of its eventual initial public offering for ordinary investors, not just giant funds and hedge funds. Sarah Friar, OpenAI’s chief financial officer, said the company wants retail buyers in the deal as it prepares for a United States listing. (cnbc.com) That is unusual because the hottest stock offerings usually go first to institutions that can place huge orders in a few phone calls. OpenAI is making the opposite pitch: if millions of people use ChatGPT, some of them should be able to buy the stock at the offering price too. (cnbc.com) Reuters reported this listing could come as soon as the second half of 2026, and bankers are already treating it like one of the biggest United States technology offerings in years. Reuters also said OpenAI could seek a valuation of up to $1 trillion, which would put it in the same size class that forces index providers, exchanges, and regulators to plan ahead. (reuters.com) The squeeze comes from timing. TradingKey and other market watchers now place OpenAI, Anthropic, and SpaceX in the same 2026 window, with SpaceX discussed for midyear, Anthropic for October, and OpenAI for late 2026. (tradingkey.com) When three giant private companies try to list close together, they all chase the same pool of money. Mutual funds, pension funds, and sovereign wealth funds may want all three, but each fund has position limits, cash limits, and risk committees that slow how much it can buy at once. (pitchbook.com) That can hurt smaller companies that planned to go public in the same season. PitchBook warned that mega-offerings can absorb attention, analyst coverage, and institutional demand, leaving later listings to fight for the scraps after the biggest names have already eaten. (pitchbook.com) The pressure does not stop at the stock market door. Yahoo Finance, citing Crunchbase data, said global startups pulled in about $300 billion across roughly 6,000 deals in the first quarter of 2026, with artificial intelligence driving much of that surge, so a few giant exits could pull even more capital toward the biggest winners and away from smaller private companies still trying to raise late-stage rounds. (finance.yahoo.com) OpenAI’s retail plan also lands as Wall Street is debating whether market plumbing built for normal listings can handle trillion-dollar newcomers. Bloomberg reported in March that major index companies were considering rule changes to deal with offerings from companies like SpaceX, OpenAI, and Anthropic, because benchmark funds may need a cleaner way to absorb stocks that arrive at enormous size. (bloomberg.com) So the story is not just that OpenAI wants everyday investors in its deal. It is that one company’s listing plan is colliding with two other mega-offerings at the same moment, and Wall Street is now trying to figure out whether 2026 will reopen the initial public offering market or jam it.
