- S&P Dow Jones Indices decided on June 4, 2026 to make "no changes" to S&P 500 eligibility criteria, including financial viability screens, the 12-month seasoning period, and the minimum investable weight factor (IWF) of 10% public float.
- SpaceX had sought rule waivers to accommodate a roughly 3% IPO float and its current unprofitability — the company carries a $29 billion debt load tied to AI infrastructure spending — and would have triggered an estimated $14 billion in passive fund buying, per Bloomberg Intelligence.
- OpenAI stood to gain more than $8 billion and Anthropic roughly $4.6 billion from similar passive inflows if the MegaCap rules had been loosened, but the door for their fast-track entry is now closed.
- Nasdaq and FTSE Russell have already moved in the opposite direction: Nasdaq cleared SpaceX for Nasdaq-100 inclusion within 15 trading days (vs. the usual three months), and FTSE Russell will add it to the Russell Top 500 after the fifth trading day post-IPO.
- S&P Dow Jones Indices did carve out a single concession, relaxing IWF rules for lower-profile benchmarks like the S&P Total Market Index and Dow Jones US Total Stock Market Index, which could still let SpaceX in faster through those trackers.
- Morningstar valued SpaceX at $780 billion in the lead-up to its IPO — less than half the $1.75 trillion the company was reportedly targeting — calling it "significantly overvalued," with strengths concentrated in Starlink and rocket launch.
- Roughly $7.5 trillion in passively managed funds track the S&P 500, including offerings from Vanguard and Fidelity, which is why index inclusion decisions are themselves market-moving events.
Why it matters: By refusing to bend its profitability and float rules, S&P Dow Jones Indices denied SpaceX, OpenAI, and Anthropic a combined $26.6 billion in passive fund buying estimated by Bloomberg Intelligence, shielding retirement and index-tracking portfolios from accelerated exposure to unprofitable AI-linked companies — but SpaceX can still ride the Nasdaq-100 and Russell Top 500 fast lanes that competing index providers already opened.
