Everything You Need to Know About the SpaceX Trading Debut

Elon Musk’s SpaceX is set to make its stock-market debut Friday in the largest IPO ever—and perhaps the most closely watched. The company sold an outsized portion of the offering to individuals. Its performance on Friday will be a crucial gauge of investor appetite for mega-offerings from OpenAI and Anthropic expected later this year.

The rocket maker, which derives most of its revenue from its satellite internet unit and has a nascent artificial-intelligence business, will trade under the ticker “SPCX.” It sold 555.6 million shares at $135 each, raising about $75 billion in a deal that valued the company at roughly $1.77 trillion.

When will shares open for trading?

SpaceX executives are set to ring the Nasdaq’s opening bell in New York, but shares in buzzy initial public offerings don’t tend to start trading until later in the day.

Bankers leading an IPO typically want to match buyers and sellers for about 10% of the shares sold before opening trading to lessen volatility. For SpaceX, that would be about 55 million shares, or roughly $7.5 billion worth.

Because pre-IPO investors are restricted from selling shares for a while, it can take time to find willing sellers among those who bought shares in a high-demand IPO.

Shares of Alibaba , the largest U.S. IPO until SpaceX, opened for trading a little before noon in its 2014 offering. Last year, one of the highest-profile offerings was that of software maker Figma , whose shares started trading just before 2 p.m.

It is possible that SpaceX’s bankers will decide to start trading without matching the typical portion of orders to ensure the shares have several hours of trading on their first day, people familiar with the matter say.

How volatile will the stock be?

Bankers and traders expect SpaceX’s share price could be volatile in initial trading, thanks in part to the large portion of its shares expected to be held by individual investors. Some who anticipate individuals will rush into the shares worry they could just as easily get spooked and rush out.

Any sharp movement in stock price could trigger so-called circuit breakers that could pause trading. For most newly listed companies, a 10% swing in either direction prompts a five-minute pause. Companies that had their shares halted include Figma and Cerebras Systems , the chip company whose shares soared in its May debut.

These forced timeouts applied to single stocks came after the so-called flash crash in 2010, when the Dow Jones Industrial Average fell 700 points in eight minutes before recouping much of the loss.

What is all the talk about the ‘green-shoe’ option?

If the stock starts trading erratically, bankers have a secret weapon to attempt to calm things down.

Underwriters typically sell more shares to investors than an IPO’s total offer size, colloquially called the green shoe. In SpaceX’s case, they sold about 15% more shares than the stated offering size.

Because this means they technically allocated more than the offering amount, the so-called stabilisation agent, in this case, Morgan Stanley , needs to buy back the excess number of shares to deliver them. If the stock starts to fall, the bank will buy the shares in the open market, which helps buoy the stock price. If the stock isn’t faltering, the stabilisation agent can buy the additional shares they need to deliver to investors directly from the company.

The term “green shoe” comes from the first company to employ a version of this method years ago, a shoemaker that was a predecessor to Stride Rite. When Meta Platforms , then known as Facebook, went public in 2012, its shares started dropping and its bankers stepped in to buy more shares.

How will Elon Musk’s take-it-or-leave-it pricing fare?

Like all things Musk, SpaceX’s IPO bucked the norms. Instead of approaching prospective investors with a possible price range for shares ahead of the IPO and incorporating their feedback, the company set an exact share price from the beginning: $135.

The idea was to limit drama for what is already the biggest IPO of all time. It did, however, remove what many see as an important step along the way: price discovery. The success of this approach will partly be judged by how SpaceX’s shares trade Friday. If the stock surges, critics will say SpaceX left money on the table by not pricing shares higher. If the stock falls or trades flat, there will likely be critiques that SpaceX and its advisers overestimated demand.

Will the machinery hold up—and what will be the wider market impact?

The sheer size of SpaceX’s IPO will test the trading infrastructure at Nasdaq and could have ripple effects in the broader market.

Nasdaq has practiced with mock openings to make sure its trading platform is prepared. When Facebook went public, some investors who tried to change or cancel orders ahead of trading didn’t get confirmations because of a technology malfunction. The confusion contributed to Facebook shares dropping on the first day of trading. They didn’t return back above their IPO price for more than a year.

Meanwhile, some market watchers expect added activity Friday in stocks that individual investors might sell to buy SpaceX shares, such as those of technology companies and Musk’s electric-car maker Tesla . Such sales already appeared to be under way earlier in the week, when individual investors dumped single-stock holdings on a net basis for two days in a row, according to Vanda Research. (To be sure, those sales came on days that were poor showings for tech stocks broadly.)

It will take several days for SpaceX shares to show up in any major index funds , so the offering’s wider impact on the market could play out over the next several weeks or longer.

When markets become volatile, many property investors make the same mistake: they allow emotion to drive decisions that should be guided by strategy.

According to Melbourne buyers’ advocate and Mecca Property Group founder, Abdullah Nouh, periods of uncertainty often reveal the difference between investors who build long-term wealth and those who become distracted by short-term market noise.

In an environment where news travels faster than ever before, sentiment can shift rapidly. A single interest rate decision, inflation update or alarming headline can trigger uncertainty among buyers and investors, even when the underlying fundamentals remain largely unchanged.

Nouh argues that market panic is rarely driven by hard data alone.

Instead, uncertainty creates a psychological response that can lead buyers to delay decisions, investors to hesitate, and vendors to become unrealistic or desperate.

The danger, he says, is that these reactions are often expensive.

A buyer who pauses because the market feels uncertain may find themselves paying more for less months later after conditions improve. Waiting for perfect clarity can be a costly strategy because markets rarely provide it.

The distinction between reacting and making a considered decision becomes even more important during periods of volatility, when the pressure to respond quickly is at its greatest.

OPPORTUNITY OFTEN HIDES IN UNCERTAINTY

While many investors see volatility as a threat, Nouh believes it can also create opportunities.

In strong rising markets, momentum often carries deals forward, and confidence becomes self-reinforcing. In more challenging conditions, however, the quality of an asset becomes far more important.

Properties that are well located, appropriately priced and supported by strong fundamentals tend to hold their value. Assets buoyed largely by market sentiment often struggle when conditions soften.

Periods of uncertainty can also create opportunities for buyers willing to remain disciplined.

Motivated sellers may emerge, competition can ease, and negotiation becomes easier. These opportunities are not always obvious, but they can provide significant advantages for investors who remain focused on long-term objectives rather than short-term headlines.

LOOKING BEYOND THE HEADLINES

A key theme in Nouh’s analysis is the need to separate market sentiment from market reality.

While investor confidence may fluctuate, many of the structural forces supporting Australian property remain in place.

Rental markets remain tight across most major cities, vacancy rates are low, and population growth continues to place pressure on housing supply.

These factors have not disappeared because of a shift in market mood.

What has changed is affordability.

Higher interest rates have increased borrowing costs and put pressure on the cash flow of investors carrying debt. While this represents a genuine challenge, Nouh argues it should not be confused with evidence that the broader property market is fundamentally broken.

Understanding that distinction is critical for investors seeking to make rational decisions.

STICKING TO THE PLAN

Ultimately, Nouh believes investors should revisit the goals that informed their strategy before market sentiment changed.

If an investment strategy was sound before a negative headline appeared, it may remain sound afterwards.

For many investors, periods of volatility simply expose weaknesses that already existed in their approach.

The investors who build wealth across multiple property cycles are rarely those who perfectly time the market. Instead, they are the ones who maintain a clear strategy and continue executing it while others become distracted by short-term uncertainty.

Markets will continue to fluctuate, sentiment will rise and fall, and economic conditions will change.

But for investors focused on long-term wealth creation, the greatest risk may not be volatility itself. It may be allowing fear to override a well-considered plan.

As Nouh argues, the current uncertainty is not necessarily something to fear. In many cases, it is simply something to understand.
