Will SpaceX join the S&P 500?

Updated from live prices and SEC filings

Not before June 2027. The S&P 500 requires 12 months of trading after an IPO, and SpaceX listed on 12 June 2026. It must also show positive GAAP earnings in its latest quarter and over its last four quarters combined, and S&P decided in June 2026 not to fast-track very large IPOs.

The short answer

SpaceX is not in the S&P 500 and cannot join before June 2027. The index only considers companies that have traded for at least 12 months after their IPO, and SpaceX started trading on Nasdaq on 12 June 2026. Even then, it has to pass the index's profitability and float tests, and the final decision rests with S&P's Index Committee.

SpaceX is already in the Nasdaq-100, which it joined in July 2026 under a fast-entry rule Nasdaq added in May 2026.

The S&P 500 rules, and where SpaceX stands

RuleRequirementSpaceX
Trading historyAt least 12 months on an eligible exchange after the IPOListed 12 June 2026, so eligible from June 2027
Market valueUS$22.7 billion or more (the level set in July 2025; S&P reviews it regularly)About $2 trillion, far above it (live SPCX price)
ProfitabilityPositive GAAP net income in the latest quarter and over the last four quarters combinedNet income of $4.40B in Q3 2026, its first profit as a listed company, but a net loss of $413M over the first nine months of 2026
FloatInvestable weight factor of at least 0.1, roughly 10% of shares freely tradableThe IPO sold 555.6 million shares, about 4% of roughly 13.6 billion shares; more become tradable as lock-ups end
SelectionAt the Index Committee's discretion, even when every rule is metNot yet considered

Profitability is the open question

Q3 2026 was SpaceX's first profitable quarter as a listed company: net income of $4.40B on revenue of $14.58B. About $1.61B of that came from below the operating line (other income, net interest income and a tax benefit), and management said fourth-quarter gross margins should normalise after one-time benefits in Q3.

For a review in mid-2027, the four quarters that count would most likely run from Q2 2026 to Q1 2027. The two reported so far add up to a profit of about $3.86B: a net loss of $541M in Q2 2026, from SpaceX's 10-Q, and net income of $4.40B in Q3. SpaceX would then need Q1 2027 itself to be profitable and the four-quarter total to stay positive.

S&P decided not to change the rules

S&P Dow Jones Indices consulted in 2026 on whether to change how very large new listings enter its US indices. On 4 June 2026 it announced no changes to the S&P 500 methodology, so there is no fast-entry route for mega-cap IPOs.

The Nasdaq-100 took the opposite approach. Since May 2026, a new listing whose full market value would rank in the index's top 40 can skip the usual three-month wait, which is how SpaceX joined it within weeks of its IPO.

What inclusion would mean

When a company joins the S&P 500, funds that track the index have to buy its shares in proportion to its float-adjusted market value. That buying is why index additions are closely watched. For SpaceX, the float adjustment matters: only freely tradable shares count, so the weight would be well below its full market value while Elon Musk and other insiders hold most of the stock.

Until then, the main dates for SPCX holders are the remaining lock-up releases: see the SpaceX lockup calendar.

Questions and answers

Is SpaceX in the S&P 500?

No. SpaceX is not in the S&P 500. It is in the Nasdaq-100, which it joined in July 2026.

When could SpaceX be added to the S&P 500?

June 2027 at the earliest, once it has traded for 12 months, and only if it also passes the profitability and float tests and the Index Committee selects it.

Why didn't SpaceX join the S&P 500 straight away?

The S&P 500 has no fast-entry rule for new listings. S&P consulted on adding one and announced on 4 June 2026 that it would not change the S&P 500 methodology.

Is SpaceX profitable?

It made net income of $4.40B in Q3 2026, its first profit as a listed company, but a net loss of $413M over the first nine months of 2026.
