SynopsisSpaceX will not get a quick entry into the S&P 500 index. S&P Dow Jones Indices will maintain its eligibility rules. This decision affects the planned initial public offerings of AI companies Anthropic and OpenAI. Companies must now wait 12 months after going public. SpaceX also needs to become profitable to be considered.SpaceX has been denied a fast track into the S&P 500 when the rocket and satellite company goes public, in a ruling that cuts off quick access to one of the biggest pools of Wall Street money.S&P Dow Jones Indices said Thursday it would maintain eligibility requirements for its benchmark following months of consultation with participants - closing the door on fast-track entry for Elon Musk's company.The decision will also affect the expected IPOs of AI giants Anthropic and OpenAI.The S&P 500 is a list of the 500 most important publicly traded companies in America - including Apple, Microsoft and Nvidia.Millions of everyday investors, pension funds and retirement accounts put their money into funds that automatically buy every stock on that list - mounting to trillions of dollars in so-called "passive funds."Getting added to the S&P 500 means a flood of automatic buying that can push a company's stock price significantly higher.The organization announced it will keep a rule requiring newly public companies to wait 12 months before they can be considered for inclusion -- and will not make exceptions based on a company's size.The rule - called a "seasoning period" - exists to make sure a company has been publicly traded long enough for investors to get a reliable sense of what it's actually worth, rather than buying in a frenzy on day one.In another setback for SpaceX, according to current rules, the company will stay off the list until it turns a profit, regardless of how long it has been trading.According to its IPO filing, SpaceX posted a net loss of $4.94 billion in 2025. It also posted a loss in the first quarter of this year.But in one boost for SpaceX, passive funds tracking the Nasdaq 100 - a rival index -- will be compelled to buy SpaceX shares sooner.Nasdaq recently introduced a fast-entry mechanism that allows new listings with large enough market values to join the index just 15 trading days after an IPO. ...moreElevate your knowledge and leadership skills at a cost cheaper than your daily tea.Subscribe Now
