S&P Bars $1.8 Trillion SpaceX IPO from Quick Entry, Keeps 12-Month Rule
NDAQ•S&P Dow Jones Indices will keep its 12-month seasoning period and current profitability and public-float rules for S&P 500 eligibility, blocking potential IPOs such as SpaceX, valued at $1.8 trillion, from fast entry. Nasdaq cut its Nasdaq 100 wait to 15 trading days and FTSE Russell to five days.
1. S&P Maintains Existing Requirements
S&P Dow Jones Indices has opted to retain its 12-month seasoning period and existing profitability and public-float criteria for S&P 500 eligibility, declining proposals to accelerate entry for mega-cap IPOs.
2. Rival Indexes Shorten Waiting Period
Nasdaq recently reduced its Nasdaq 100 inclusion wait to 15 trading days from three months, while FTSE Russell now admits new listings after just five trading days.
3. Delayed Passive Fund Flows
Fast inclusion would have driven roughly $14 billion in passive buying into SpaceX, about $8 billion into OpenAI and $4.6 billion into Anthropic PBC; the decision defers those inflows.
4. Implications for SpaceX IPO
SpaceX’s forthcoming IPO, with a projected $1.8 trillion valuation, must now trade for at least one year and meet public-float and profitability standards before any S&P 500 entry.
