What Just Changed: SpaceX Is Going Public

For years, "CommSec SpaceX" was a search that led to disappointment — SpaceX was a private company, retail investors could not buy shares, end of story.

That changed in 2026. SpaceX confidentially filed with the SEC in April and published its full S-1 prospectus on 20 May 2026. The company is targeting a Nasdaq IPO under the ticker SPCX, with pricing on 11 June and first-day trading on 12 June 2026. At the offered price of US$135 per share across roughly 556 million shares, this would raise ~US$75 billion and value SpaceX at approximately US$1.75 trillion — the largest IPO in stock market history if completed at that figure.

SpaceX also filed a separate Australian prospectus, specifically to allow Australian retail investors to participate through approved domestic brokers.

How We Verified This Information

The facts above come from the S-1 filed with the SEC on 20 May 2026 (available at sec.gov), SpaceX's Australian prospectus filings on asic.gov.au, CommSec's IPO Centre page updated in early June 2026, and reporting from the Australian Financial Review, CNBC, and Reuters. Financial figures (valuation, share price, timing) are sourced from the S-1 and supplementary Australian prospectus. This article was last updated 9 June 2026 — verify current status at commsec.com.au before acting.

Before the IPO: The SpaceX Access Problem

Until the S-1 filing, the honest answer was no — not directly. SpaceX was a privately held company controlled by Elon Musk. It had no ASX listing, no NYSE/Nasdaq ticker, and no public market for retail shares. CommSec, like every other retail broker, could not offer something that did not trade publicly.

This is worth stating plainly because many articles have circulated claiming you could "invest in SpaceX" via various workarounds. Some of those routes carried real exposure to SpaceX indirectly (detailed below), but none gave you actual SpaceX shares through a standard CommSec account.

The IPO Window: CommSec as Lead Retail Broker

CommSec has been designated as the lead Australian retail broker for the SpaceX IPO offer. This means CommSec's IPO Centre was the primary channel through which Australian retail investors could apply for shares at the IPO price (US$135).

Key details for the retail window:

• Application deadline: 5pm AEST, 10 June 2026 (CommSec warned it may close applications earlier)
• Minimum investment: subject to CommSec's IPO terms — check your International Shares Account for the exact minimum lot size
• You need an active CommSec International Shares Account with funded International Wallet before applying
• Settlement and pricing confirmed via a supplementary Australian prospectus expected on 11 June

If you are reading this after 10 June 2026, the IPO application window is closed. Move to the open-market section below.

Step-by-Step: How to Buy SPCX via CommSec International

During the IPO (application window, closed after 10 June)

1. Log in to CommSec > Trade > IPOs > IPO Offers
2. Locate the SpaceX (SPCX) retail offer
3. Review the Australian supplementary prospectus
4. Enter your application amount in AUD (funds converted at spot rate)
5. Confirm — you may receive a partial allotment or none at all

After listing (12 June onwards — open market)

1. Log in to CommSec
2. Go to International Shares (not the standard ASX view)
3. Search SPCX on Nasdaq
4. Enter a limit order (recommended over market order for a high-volume debut)
5. Ensure your International Wallet has sufficient USD or AUD to cover settlement

Note on the W-8BEN form: CommSec requires all international shares account holders to complete a W-8BEN form. This reduces US withholding tax on dividends from 30% to 15% under the Australia-US double tax treaty. SpaceX currently pays no dividend (it is reinvesting all capital), so this is less immediately relevant, but it is still required account setup.

---

After the IPO: Buying SPCX on the Open Market

Once SPCX begins trading on Nasdaq on 12 June (or thereafter), the process is identical to buying any US-listed stock on CommSec International. You search the ticker, review the live price, and place an order.

CommSec International trades settle in USD and typically take T+1 (next business day) to complete. Your International Wallet needs to hold USD or you can fund it with an AUD-to-USD conversion.

Other brokers also offer Nasdaq access: Stake, Interactive Brokers (IBKR), moomoo Australia, and Tiger Brokers. IBKR tends to have the lowest commission ($0.005/share on US stocks), which matters for large purchases. For a detailed comparison of CommSec International versus IBKR for Australian investors, see our Interactive Brokers Hong Kong review which covers the same fee structures.

Indirect Routes: DXYZ and Other Proxies

Before the IPO, the main way to get indirect SpaceX exposure through a publicly traded instrument was:

Destiny Tech100 (DXYZ, NYSE) A closed-end fund that holds stakes in up to 100 private tech companies. SpaceX was its largest holding at roughly 16% of the portfolio. Because DXYZ trades on the NYSE, CommSec International customers could buy it like any US stock. The thesis: if SpaceX's private valuation rises or it eventually goes public, DXYZ's NAV should reflect that.

Alphabet / GOOGL Google invested in SpaceX in 2015 as part of a ~US$1 billion round. That stake is a small fraction of Alphabet's overall business. Buying GOOGL gives you fractional, diluted SpaceX exposure — but calling it a "SpaceX proxy" is a stretch.

Scottish Mortgage Investment Trust (SMT, LSE) Baillie Gifford's SMT has held private tech companies including SpaceX at various points. Not accessible via CommSec International (which covers NYSE/Nasdaq, not LSE) without using a separate broker.

---

The DXYZ Premium Problem

DXYZ was a popular SpaceX proxy trade precisely because SpaceX was private and DXYZ was the easiest way to get listed-market exposure. That trade had a structural problem from the start: DXYZ has consistently traded at a premium to its net asset value (NAV).

At its peak, DXYZ traded at multiples above NAV. As of early 2026, the fund's NAV was reported at around US$19.97/share while the stock traded in the US$29–30 range — roughly a 50% premium. That means you were paying 50 cents extra for every dollar of underlying assets, including the SpaceX stake.

Now that SpaceX itself is listing publicly, the case for holding DXYZ as a SpaceX proxy weakens considerably. Investors who wanted SpaceX exposure will increasingly hold SPCX directly rather than pay a closed-end fund premium. Whether DXYZ's NAV premium compresses significantly post-SPCX listing is a real risk worth pricing in before buying.

Australian Tax Angle: W-8BEN, CGT, and USD Conversion

A few practical tax notes for Australians buying SPCX:

W-8BEN: Required by CommSec International. Without it, US withholding tax on any future SpaceX dividends would be 30%. With it, reduced to 15% under the Australia-US DTA. SpaceX pays no dividend currently, but file the form regardless — it is standard for all US holdings.

Capital Gains Tax: If you buy SPCX and sell at a profit, the gain is assessable income in Australia. Hold for more than 12 months and you qualify for the 50% CGT discount — only half the capital gain is added to your taxable income. This applies whether you bought at IPO or on-market.

USD conversion: CommSec International holds USD in your International Wallet. When you sell SPCX and repatriate to AUD, the exchange rate at that time affects your AUD return. A rising AUD against USD reduces your returns when converting back. This is a separate exposure from the stock price itself.

US estate tax: US-listed assets above roughly US$60,000 are subject to US estate tax at rates up to 40% for non-US citizens. This is a real risk for larger positions — consult a tax adviser if your SPCX holding plus other US-listed assets approach that threshold.

For a fuller treatment of these tax layers, see our ASX ETF vs US ETF tax guide.

Risks You Should Understand

SpaceX's own Australian prospectus describes the shares as "highly speculative." That is not boilerplate. A few specific risks worth naming:

Valuation risk at US$1.75 trillion. SpaceX is profitable primarily through Starlink (satellite internet), which recorded roughly US$1.19 billion profit on roughly 10.3 million subscribers. The rest of the business — rockets, Starship — runs at a loss. A US$1.75 trillion valuation prices in decades of future growth. If Starlink growth slows or competition intensifies, the valuation has a long way to fall.

Musk concentration risk. Elon Musk retains voting control of SpaceX post-IPO. He simultaneously runs Tesla, X (formerly Twitter), xAI, and Neuralink. His attention and any controversy around his other ventures affects SpaceX's stock directly.

Lock-up expiry. Large insiders will face lock-up periods before they can sell. When those expire (typically 90–180 days post-IPO), additional supply hits the market and can push the price down.

IPO allotment uncertainty. For the CommSec IPO window, retail applicants may receive less than they applied for — or nothing — because global institutional demand will absorb most of the offer.

FAQ

Can I buy SpaceX shares on CommSec?

Yes — from 12 June 2026, SPCX trades on Nasdaq and CommSec International gives you access to Nasdaq. You can buy SPCX like any other US stock through CommSec's International Shares platform.

Is SpaceX listed on the ASX?

No. SpaceX is listing on Nasdaq (SPCX). It is not and has no plans to list on the Australian Securities Exchange.

What is DXYZ and should I use it to invest in SpaceX?

Destiny Tech100 (DXYZ) is a NYSE-listed closed-end fund that held SpaceX as its largest holding at ~16% of its portfolio. Now that SpaceX is listing directly as SPCX, DXYZ's role as a SpaceX proxy is less compelling — and it trades at a premium to NAV, meaning you pay more than the underlying assets are worth.

Can I use CommSec Pocket to invest in SpaceX?

Not directly. CommSec Pocket invests in ASX-listed ETFs covering themes like technology, sustainability, and global markets. None of those ETFs currently hold SpaceX as a meaningful position. For direct SpaceX exposure you need CommSec International.

Do I need a W-8BEN form to buy SPCX on CommSec?

Yes. CommSec International requires a W-8BEN on file for all US holdings. It reduces withholding tax on future dividends from 30% to 15%. SpaceX currently pays no dividends, but the form is still required as part of account setup.

What happens if SpaceX's IPO is delayed or cancelled?

IPO timelines can shift due to market conditions or regulatory issues. If the listing is delayed past 12 June, CommSec will notify applicants. Application funds are not drawn until allotment is confirmed.

Is the SpaceX IPO available to all Australian residents?

CommSec International is available to Australian residents who are not US persons. You need an active CommSec Share Trading Account, an International Shares Account, and funded International Wallet. CommSec may place restrictions based on citizenship or tax residency requirements from its international custodian.

The Bottom Line

The "CommSec SpaceX" question has a different answer in June 2026 than it did for the past decade. SpaceX is going public. Australian investors can participate through CommSec International — either via the IPO application window (now closed as of 10 June) or by buying SPCX on the open market from 12 June onwards.

The mechanics are straightforward: CommSec International account, funded International Wallet, search SPCX on Nasdaq, place an order. The harder question is whether the price is right. A US$1.75 trillion valuation prices in Starlink's continued growth, Starship's eventual commercial success, and Elon Musk's sustained focus on the business. None of those are guaranteed.

For investors who missed the IPO application or want to study the price action before committing, buying SPCX post-listing via CommSec International remains an option. For those who prefer indirect exposure with some diversification, DXYZ still holds SpaceX — just with a NAV premium overhead that is worth understanding before you pay it.
