On June 12, SpaceX is expected to list on Nasdaq under the ticker SPCX. If the target valuation holds, it will be the largest IPO in history — somewhere between $1.75 trillion and $2 trillion for a combined entity that now includes SpaceX, xAI (Musk’s AI company), and X (formerly Twitter).

We’re not financial analysts. We’re not here to tell you whether SpaceX is worth $2 trillion, or whether you should try to buy shares. What we do think is worth your attention is the mechanism by which this IPO connects to your superannuation — whether you have any interest in SpaceX or not.

The index inclusion question

When a company enters a major stock index — the Nasdaq 100, the S&P 500 — every fund that tracks that index must buy shares proportionally. That’s how passive investing works: the fund mirrors the index, no discretion applied.

Until recently, new listings had to “season” before index inclusion. Facebook took seven months after its IPO before entering the Nasdaq 100. Airbnb took roughly a year. Tesla took three years before S&P 500 inclusion.

In March 2026 — effective 1 May 2026 — Nasdaq changed its rules. Any newly listed company whose market cap ranks in the top 40 of the Nasdaq 100 (approximately a $100B threshold) is now eligible for “fast entry” after just 15 trading days. No seasoning period. No minimum float required.

Reuters reported that rapid index inclusion was a stated condition of SpaceX choosing Nasdaq over NYSE. Both exchanges competed for the listing. Nasdaq changed its methodology. SpaceX chose Nasdaq. Under the new rules, SpaceX is expected to enter the Nasdaq 100 on approximately July 6 — 15 trading days after listing.

Separately, S&P Dow Jones Indices ran a public consultation on reducing its own 12-month seasoning period to 6 months and potentially waiving its four-quarter GAAP profitability requirement for large companies. The consultation window closed on 28 May 2026. SpaceX posted a $4.94 billion net loss in 2025 — it would currently fail the profitability test.

These are the questions worth sitting with: Is it appropriate for index methodology — the rules that govern what retirement savers are forced to own — to be changed in ways that appear responsive to a specific listing? And who is accountable when it goes wrong?

The Nasdaq conflict worth understanding

Nasdaq occupies an unusual position. It operates as both a for-profit stock exchange (which profits from listing fees and trading volume) and an index provider (which controls which stocks enter the Nasdaq 100, driving billions in passive fund flows).

When Nasdaq changes its index rules in a way that benefits a company that chose to list on Nasdaq over a competitor exchange, those two roles are in direct tension. EU financial regulation requires operational separation between benchmark administration and other business activities that may create conflicts. US regulation does not impose the same requirement.

CalPERS, the New York State Common Retirement Fund, and the NYC Comptroller — representing over $1 trillion in combined pension assets — sent a joint letter to SpaceX describing its governance structure as “the most management-friendly in the history of the U.S. public markets.” Musk holds 43% of SpaceX equity but controls 85% of voting rights through a dual-class share structure. He cannot be removed as CEO without his own consent.

These are real institutions raising real questions. We’re surfacing them here because they’re worth knowing.

What this means for Australian investors

The Australian angle is specific. CommSec has been named as the lead Australian retail broker for the SpaceX IPO and is reportedly targeting up to $1 billion from Australian retail investors. Macquarie Capital — one of 23 underwriters — is separately targeting Australian superannuation funds.

But the more structural exposure doesn’t require any decision on your part:

  • NDQ (BetaShares Nasdaq 100 ETF, ASX-listed) will gain SpaceX exposure approximately 15 trading days post-IPO — the earliest exposure for any ASX-listed fund.
  • VTS (Vanguard US Total Market ETF) will include SpaceX following Russell 1000/3000 inclusion.
  • IVV (iShares S&P 500 ETF) and V500 (Vanguard’s S&P 500 ETF, launched March 2026) will include SpaceX if and when S&P 500 inclusion proceeds — currently Q4 2026 or Q1 2027 under the proposed rule changes.
  • Superannuation funds with international index exposure — including AustralianSuper, which has over $240 billion invested internationally — will accumulate SpaceX exposure automatically through those indices.

You don’t need to make a choice. The index will make it for you.

The questions we’d want answered

We’re not qualified to tell you what SpaceX is worth, and this isn’t financial advice. But here are the questions we’d want answered before we felt comfortable with any of this:

On the IPO mechanics: Of SpaceX’s $75–$80 billion raise, approximately $62.8 billion (78%) has reportedly been pre-pledged to debt repayment and existing investor payouts. How much of this capital raise actually funds future growth versus allowing early investors to exit at a 94x trailing revenue multiple?

On index rule changes: Should index methodology — the rules that determine what passive retirement savings must buy — be subject to independent regulatory oversight rather than self-regulation by for-profit entities with commercial relationships to the companies being included?

On governance: Is it reasonable to ask retirement savers to become involuntary shareholders in a company where they have, effectively, no voice — where voting control is permanently concentrated in a single individual who cannot be removed, who simultaneously runs five other companies, and who holds a government advisory role with direct relevance to the company’s federal contracts?

On the Tesla precedent: Tesla entered the S&P 500 in December 2020 with forced buying estimated at $51–$85 billion. In the month before inclusion, Tesla’s stock rose over 70% as traders front-ran the forced purchases. Then it fell 7.86% in the two days after formal inclusion. Retirement savers who bought through index funds in the run-up overpaid relative to what they’d have paid under the old rules. We’re not saying the same will happen here. We’re noting the dynamic is real and worth understanding.

These are open questions. We don’t think you should necessarily avoid SpaceX exposure, or demand your super fund divest, or do anything specific. We do think that when the rules governing passive investing are rewritten in ways that affect every person who has retirement savings in an index fund, it’s worth being aware the rewrite happened.

Whether the answers are satisfactory is something you’ll need to decide for yourself.
