One of the most anticipated share market listings in history is about to take place, with Elon Musk's SpaceX preparing to debut on the Nasdaq stock exchange in what could become the largest initial public offering ever conducted.

Reports indicate the company plans to raise approximately US$75 billion at a fixed price of US$135 per share, valuing the business at around US$1.75 trillion.

For years, ordinary investors could only watch from the sidelines as SpaceX remained privately owned. Now, Australians are asking a simple question: how can they become shareholders in the company that launches rockets, deploys satellites and is attempting to make humanity a multi-planetary species?

What is SpaceX?

Founded by Elon Musk in 2002, SpaceX has transformed the global space industry through reusable rocket technology, commercial satellite launches and the rapidly expanding Starlink satellite internet network.

The company operates:

• Falcon 9 reusable rockets
• Falcon Heavy launch systems
• Dragon spacecraft
• Starlink satellite internet
• Starship deep-space development program

SpaceX has become a critical supplier to both commercial customers and government agencies, including NASA and the United States military.

The biggest IPO in history?

According to published reports, SpaceX intends to sell approximately 555 million shares at US$135 each, raising around US$75 billion and valuing the company at roughly US$1.75 trillion. If completed, it would comfortably surpass previous IPO records.

Demand has reportedly been enormous, with some reports suggesting the offering has already attracted multiple times the available demand.

The company is expected to trade under the ticker code SPCX on Nasdaq.

How can Australians invest?

Australians generally cannot purchase shares directly from the company itself unless they receive an allocation through a participating broker.

However, Australian investors may be able to participate through:

• International share trading accounts
• Australian brokers offering US share access
• Global investment platforms
• Wealth management firms with IPO allocations
• US brokerage accounts where legally available

Many Australian investors already access US markets through international trading facilities provided by local brokers.

If investors do not obtain shares during the IPO process, they will generally be able to purchase stock once public trading begins.

What should investors know before buying?

SpaceX may be famous, but fame does not eliminate investment risk.

While revenue continues to grow strongly, reports indicate the company remains unprofitable and is investing heavily in future technologies including Starship and next-generation satellite infrastructure.

Analysts have also questioned whether the proposed valuation leaves enough upside for new investors. Some commentators argue that future growth expectations have already been substantially priced into the offering.

Investors should remember that buying a share in a popular company is not the same as buying a guaranteed investment success.

Why Australians are interested

SpaceX represents something larger than a traditional stock market float.

For many investors, the company sits at the intersection of:

• Space exploration
• Artificial intelligence
• Satellite communications
• Defence technology
• Advanced manufacturing
• Global internet infrastructure

The listing also provides ordinary investors with access to a business that many previously regarded as one of the world's most valuable private companies.

A new era for public investors

For years, the biggest gains from technology companies often occurred before public listings, benefiting founders, venture capital firms and private investors.

The SpaceX IPO changes that equation.

Whether the shares ultimately soar or struggle, Australians will soon have the opportunity to decide for themselves whether Elon Musk's vision of rockets, satellites, space travel and eventually Mars is worth investing in.

The company has already changed the space industry. Within days, investors will discover whether it can also redefine the public share market.
