S&P 500 rejected SpaceX's request for accelerated index entry, denying rule changes that would have also benefited unprofitable AI firms.

S&P Dow Jones Indices declined to modify eligibility criteria for SpaceX's IPO, refusing to shorten the seasoning period from 12 to 6 months, waive the 10 percent public float requirement, or waive profitability standards. SpaceX planned to offer only 3 percent of IPO shares publicly and carries $29 billion in debt from AI infrastructure spending. According to Bloomberg Intelligence, S&P 500 entry would have triggered $14 billion in passive fund buying for SpaceX, plus $8 billion for OpenAI and $4.6 billion for Anthropic. The Nasdaq and FTSE Russell made their own accommodations, allowing faster entry into their indexes. Morningstar valued SpaceX at $780 billion, roughly half its $1.75 trillion IPO target, primarily based on Starlink and rocket launch businesses.

What HN community is saying

Commenters broadly approved the decision, viewing it as protecting retirement accounts and preventing wealth transfer to wealthy shareholders. A technical correction noted pension funds typically do not automatically follow the S&P 500, unlike 401(k)s and IRAs. Disagreement emerged on equal-weight indexing alternatives: one commenter advocated switching to reduce tech concentration, while another warned equal-weight funds incur constant rebalancing drag and trading costs that often underperform market-weighted approaches.
