SpaceX priced its IPO at $135 per share. The stock opened at $150 on the Nasdaq under the ticker SPCX and closed near $161 after reaching an intraday high above $176. The offering sold roughly 556 million shares and raised about $75 billion, the largest IPO on record. At the close of its first session, the company’s market capitalization was above $2.1 trillion, which placed it among the most valuable U.S. companies.

The debut ended above both the offer price and the opening print, but below the session’s peak. The company that listed is Space Exploration Technologies, Elon Musk’s space exploration, connectivity and artificial intelligence business. Members of the SpaceX team rang the Nasdaq opening bell, with Musk speaking from Texas and President Gwynne Shotwell in New York City. The company marked the first trade with a post on X, which it owns: “Liftoff! First $SPCX trade complete.”

IPO price, opening price and closing price

Three different prices described SpaceX on its first day, and they reached different buyers.

The IPO price of $135 is what investors allocated shares in the offering paid. Those allocations run through the underwriting banks before the stock trades. The $135 figure was the expected price, and the deal priced there. Multiplying the offer price by the shares sold gives the size of the raise: about 556 million shares times $135 comes to roughly $75 billion. At the offer price, the implied valuation of the whole company was near $1.8 trillion.

The opening price of $150 was the first trade on the exchange. It is the price set by the opening auction once buy and sell orders were matched, and it is the earliest price most individual investors could reach through an ordinary brokerage account. The gap between the offer and the open was $15, about 11% above the IPO price. Investors who received allocations had that gain before the first trade printed. Investors who bought at the open started at $150.

The closing price near $161 was the last regular-session trade. That is roughly 19% above the IPO price and about 7% above the opening price. The intraday high above $176 was more than 30% over the offer price, so the stock gave back a meaningful part of its gains before the close. Measured from the high, the pullback was at least 8%.

At the peak, SpaceX’s market value was above $2.3 trillion. By the close it was above $2.1 trillion. Both figures exceeded the roughly $1.8 trillion implied at pricing, which shows how much value the open market added on top of what IPO buyers paid.

How the market cap figure works

Market capitalization equals share price multiplied by total shares outstanding. It is not shares sold in the IPO times price. The 556 million shares in the offering were a small slice of the company. Most of SpaceX’s stock stayed with existing holders such as employees, Musk and venture investors.

For a rough sense of scale, the closing figures can be run backward. A market value of about $2.1 trillion at a price near $161 implies on the order of 13 billion shares outstanding. That is an approximation built from rounded numbers, not a reported share count. On that rough assumption, a hypothetical price of $225 per share would correspond to a market cap around $2.9 trillion. The company’s filings are the source for the exact count, and dilution from options or new issuance can change it over time.

Why trading started late in the morning

The Nasdaq opening bell rang at the usual time, but SPCX did not trade until late morning. Large IPOs often open hours after the regular session begins, and that schedule follows from how exchange listings are priced.

On the Nasdaq, a stabilization agent sets the opening price working with the exchange’s execution team. The agent is typically one of the banks that underwrote the IPO. Order data is tracked in real time, and the exchange’s agent tests possible price points, simulating hypothetical trades to see how each would affect the market. This process is known as price discovery. The goal is an opening price at which buy and sell interest can be matched without a disorderly first trade.

Scott Bacigalupo, Nasdaq’s Senior Vice President of Capital Formation, has said that many factors go into the timing, but a primary one is how many shares will be available at the open. The larger the offering, the more complex the process and the longer it usually takes to begin trading. SpaceX sold more than half a billion shares, which made it an unusually heavy order book to clear. Investors who placed orders before the open were waiting on that auction, not on a technical delay.

The late start also matters when reading first-day volume and retail data. SPCX traded for only part of the session, while every other stock on the exchange had the full day.

Retail investors bought early and kept buying

Retail demand showed up quickly once the stock opened. Vanda Research data showed individual investors bought more than $18 million of SpaceX in the first 20 minutes of trading. That made SPCX the second most popular stock among retail traders for the day, behind only Nvidia, even though other stocks had been trading since the opening bell.

Vanda also noted that retail buying was accelerating early on: net purchases in the second 10-minute window were larger than in the first. At that pace, the firm said, SpaceX was on track not only to top the day’s most-bought list but to set records against other major IPOs of recent years.

That is a measure of net retail buying on one day. It shows strong individual-investor interest at the open. It does not show who held the stock at the end of the session or how long those buyers intended to keep it.

Where SpaceX ranked among the largest companies

SpaceX became one of the world’s most valuable public companies the moment it began trading. Shortly after noon Eastern time, its market value stood at about $2.2 trillion. At that point only five companies were larger: Nvidia (about $5 trillion), Alphabet ($4.4 trillion), Apple ($4.3 trillion), Microsoft ($2.9 trillion) and Amazon ($2.5 trillion). Those were the valuations on debut day, and all of them move with their share prices.

That ranking put SpaceX ahead of some members of the Magnificent 7 group of large tech stocks. It also put the company well above Musk’s other public company. Tesla’s market cap was around $1.5 trillion that day. With both companies public, Musk became a paper trillionaire.

The interest came from the company’s mix of businesses. SpaceX combines rocket launch, satellite connectivity and an artificial intelligence operation, and it has stated ambitions to build orbital data centers and to colonize Mars. Investors had been eager for direct exposure to that space and AI crossover, which until the IPO was available mainly to private funds and insiders.

What analysts and prediction markets expected

Expectations going into the debut were wide. On prediction markets, some bettors forecast a market cap at or above $3 trillion. Some early analyst calculations put the company’s worth below $2 trillion. That was under where the stock actually traded on day one.

Oppenheimer started coverage the day before trading with an “outperform” rating and a $190 price target. The target sat above the first-day high, so even at its peak the stock was trading below that firm’s estimate of where it could go.

Prediction markets also adjusted as the session unfolded. On Polymarket, the implied odds that SpaceX would close with a market cap above $2.2 trillion fell from 65% in the morning to 41% by the afternoon. The odds of a close above $2.4 trillion dropped from 49% to 9%. The close above $2.1 trillion landed below both thresholds. Those odds are the platform’s own pricing of bets, not forecasts from analysts. The shift tracked the stock’s move off its highs.

During the afternoon, with shares above $164, more than 20% over the IPO price, and the market cap approaching $2.2 trillion, board member Antonio Gracias said he planned to hold his stake “for as long as I can.” His firm, Valor Equity Partners, owns 7% of the company. He described SpaceX as “building the future” and said it would accrete value over a long period.

Space stocks and funds fell while SpaceX rose

The rest of the space sector did not share in the debut. In the morning, before SPCX opened, several publicly traded space companies sold off after climbing in the weeks leading up to the IPO. Virgin Galactic Holdings and Voyager Technologies were down by double digits. Rocket Lab and Planet Labs each slipped about 8%.

Space-focused funds held up somewhat better but still ticked lower. That group included Global X Space Tech, Procure Space, VanEck Space and ARK Space & Defense Innovation. Two funds moved the other way: Baron Partners and Baron First Principles, both from Baron Capital, held SpaceX shares before the IPO and were gaining.

One reading of that split is that smaller space names had served as stand-ins for SpaceX while it was private, and some of that premium came out once the real thing was available. A related narrative held that some investors were selling large tech and chip stocks to raise cash for SPCX. Both are interpretations of the day’s price action, not measured flows.

Tesla and the merger question

Tesla was roughly flat during SpaceX’s first session. The S&P 500 edged higher, and the Roundhill Magnificent 7 ETF, a fund tracking the group of big tech stocks, fell 0.6%. For the broader S&P 500, a single debut, however large, was one factor among many that day.

The listing revived talk of combining Musk’s two public companies. Wedbush analyst Dan Ives wrote days before the debut that he sees more than an 80% chance SpaceX and Tesla merge into one company in 2027. In his view, the groundwork for running the two as one organization is already in place. That is one analyst’s forecast. Neither company has announced a deal, and a merger of two companies of this size would require board approval, shareholder votes and regulatory review.

The case for waiting before buying

Not every market voice thought day one was the time to buy. Jay Woods, chief strategist at Freedom Capital Markets, said high-profile IPOs have often surged at first and then given back part of those gains. He expected the same pattern for SpaceX. In his view, better entry points could come later. He said he would wait a few weeks or even a few months, and ideally through at least one earnings cycle, before building a larger position.

Louis Navellier, founder of Navellier & Associates, said the market was in a “FOMO” phase, short for fear of missing out, driven by the SpaceX IPO. He also pointed to a common post-IPO pressure: lockup expirations. Insiders and pre-IPO investors are usually barred from selling for a set period after a listing. When those lockups end, more shares can reach the market, and insider selling can weigh on the price. Navellier said the typical IPO stalls within a few months as that happens.

His own approach is to skip IPOs entirely for about a year. That gives him four quarters of financial results and enough trading history to calculate measures such as alpha and standard deviation before deciding whether a stock fits his criteria. A new listing has no price history to measure volatility against. The first quarterly reports are also the first public look at results under public-company reporting rules. For SpaceX, that milestone arrives with its first report; SpaceX’s first earnings report and call covers how that went.

Navellier was also upbeat on the bigger picture. He said an IPO boom is good for investor confidence and could lift the broader market. He expected the investor rush to continue, and he said he thought an eventual Anthropic IPO could be even more successful than SpaceX’s.

Why the debut mattered beyond SpaceX

Some investors saw the first day as a test for the whole IPO market. Ben Narasin, founder and general partner at Tenacity Venture Capital, called a strong SpaceX debut “absolutely critical.” He warned that a weak one could stall other listings and put a “true chill” on the market.

He gave reasons a first-day pop was plausible. SpaceX could be added quickly to major stock indexes, which would force index funds to buy shares. Musk also has a large retail following, which Narasin called the “fanboy/fangirl effect,” along with backers such as Ron Baron, whose firm holds large stakes in both SpaceX and Tesla. But Narasin said there would be sellers too. He compared the setup to Facebook’s IPO in May 2012. That company, now Meta Platforms, stumbled in its debut. On that basis Narasin put the odds of a strong SpaceX opening at about a coin flip. As it turned out, the stock opened above its offer price and held most of that gain into the close.

Mark Klein of SuRo Capital called SpaceX the “bellwether” for a wave of large listings. AI developers Anthropic and OpenAI have both filed regulatory paperwork that moves them closer to going public. Klein described the IPO pipeline as a parade turning into a stampede, after flickers of activity the year before that never became a broad wave.

He also raised a capital-competition point. So much money is flowing toward a handful of giant deals, and toward large public companies raising funds of their own, such as Alphabet raising billions for its AI efforts. As a result, some major private companies may hold off and watch. Klein said that would not keep smaller IPOs off the calendar. But some of the larger offerings could slip from the second half of 2026 into 2027.

What SpaceX does

SpaceX describes itself as a space exploration, connectivity and artificial intelligence company. Its best-known operations are rocket launches and the Starlink satellite internet network. It also owns X, the social platform it used to announce its first trade, and it has an AI business. The company has said it aims to build data centers in orbit and to send people to Mars.

Each of those lines has different economics and timelines. Launch and connectivity generate revenue today. Orbital data centers and Mars colonization are long-range goals. Much of the gap between the roughly $1.8 trillion valuation at pricing and early analyst estimates below $2 trillion, on one side, and prediction-market bets on $3 trillion, on the other, comes down to how much value investors assign to those long-range ambitions versus the businesses already earning money.

Three questions the listing raises

The size of the deal put three broader questions in front of investors.

The first is whether SpaceX is good for the market as a whole. An IPO this large pulls capital in from other holdings, and the record raise means a lot of money moved into one stock at once. Navellier’s view was that an IPO boom lifts confidence across the market. Klein’s was that it could crowd out other large offerings.

The second is what happens to indexes. A company valued above $2 trillion becomes one of the largest weights in any market-cap-weighted index that adds it. Index funds must then buy shares to match. Narasin pointed to that buying as one source of support. For investors in broad index funds, the question is how much SpaceX exposure they end up with whether or not they ever buy SPCX directly. Follow-up coverage of SPCX’s next milestones tracks how that played out.

The third is what SpaceX means for individual portfolios. Investors who already own Tesla, large tech stocks or space funds may find that adding SPCX increases concentration in the same theme, the same founder or the same AI trade. The first session also showed how far apart prices can be within one day for a new listing. Buyers at the open, at the high and at the close paid prices more than $26 apart.

Reading the first day in context

A first trading session establishes a starting point, not a trend. On SpaceX’s first day, the offering priced as expected at $135. The open at $150 delivered an immediate gain to allocated investors. Retail buyers came in heavily. The stock ran above $176 before settling near $161, with a market value above $2.1 trillion.

The questions experts raised that day stay open after it. Lockups will expire. Quarterly results will show how the businesses perform. Index inclusion will bring new demand, and the IPO pipeline behind SpaceX will show whether the debut opened the door for other large listings or drew capital away from them.
