SpaceX’s Post-IPO Frenzy Reshapes the Market

SpaceX’s astonishing first days as a public company have already evolved into something larger than a successful stock market debut. What began last week as one of the biggest initial public offerings in years is now reshaping the upper ranks of the market, feeding a speculative frenzy in derivatives and exchange-traded products, and giving Elon Musk a powerful new currency for dealmaking.

On Monday and Tuesday, shares of the space and artificial intelligence company continued their rapid ascent after Friday’s debut, at one point lifting SpaceX past Amazon in market value and placing it among the world’s most valuable companies. The stock later gave back some gains, but the move was enough to underscore how quickly investors have embraced a company that sits at the intersection of two of the market’s most magnetic themes: generative A.I. and Musk.

The surge has come with a new strategic turn. SpaceX said on June 16 that it would acquire Cursor, the fast-growing A.I. coding startup also known as Anysphere, in an all-stock transaction valued at $60 billion. The deal, expected to close in the third quarter, would give SpaceX and its affiliated A.I. ambitions a stronger foothold in one of the most competitive corners of the software industry, where OpenAI and Anthropic already offer popular coding assistants.

A soaring valuation becomes a tool

The speed of SpaceX’s rise has been remarkable even by recent market standards. The company priced its IPO on June 11 at $135 a share and began trading the following day. After underwriters exercised their full option, SpaceX said the offering raised roughly $85.7 billion in gross proceeds, making it one of the largest listings ever.

In just days, that valuation ballooned further in the public market, briefly nearing or exceeding $2.7 trillion in some trading. The rally has allowed SpaceX to do something only a handful of companies can: use a richly valued stock as acquisition currency almost immediately after listing.

Cursor was not an unexpected target. In April, SpaceX had disclosed that it held an option either to acquire the company later in 2026 for $60 billion or to pay $10 billion tied to their partnership. By exercising that path now, SpaceX is moving quickly to capitalize on public investors’ enthusiasm and to deepen its push into A.I. software.

The rationale is straightforward. Coding assistants have emerged as one of the clearest commercial uses of generative A.I., and developer tools have become a battleground for the industry’s biggest players. Cursor built a strong following by offering programmers software that can generate, edit and explain code, and its appeal has rested in part on being relatively flexible in the models it uses. Whether that flexibility survives under SpaceX ownership is now one of the central questions hanging over the deal.

From landmark IPO to market spectacle

What makes SpaceX’s post-IPO run especially striking is not only the size of the move, but the machinery now building around it.

Listed options on SpaceX have begun trading, creating a new arena for bullish and bearish bets. Strategists have described the contracts as exceptionally expensive, a sign both of intense demand and of expectations for large price swings. Some traders have warned that the options market, rather than simply reflecting volatility, may be helping intensify it.

At the same time, leveraged exchange-traded funds tied to SpaceX have launched, offering investors magnified exposure to daily moves in the stock. That matters because these products, along with options activity, can force market makers and fund managers to buy or sell shares as prices move, amplifying rallies and reversals alike. Anticipation of eventual inclusion in major benchmark indexes has added another layer of technical demand.

Those dynamics have turned SpaceX into something resembling a meme stock for the mega-cap era: a company with a compelling narrative and real business scale, but also one whose short-term price action may be increasingly shaped by market structure. Analysts and investors are struggling to determine how much of the climb reflects confidence in future revenue and how much is a product of hedging flows, retail enthusiasm and momentum trading.

Even skeptics have found the trade difficult to approach. Michael Burry, the investor famous for betting against the U.S. housing bubble before the 2008 financial crisis, said he had been tempted to wager against SpaceX but backed away because the options were too expensive.

The people behind the company

The rally has also renewed attention on the leadership structure beneath Musk’s outsized public profile. Much of Wall Street’s fascination centers on Musk himself, who said over the weekend that SpaceX “might be able to reach approximately” $1 trillion in revenue in 2030, a projection that would place it in rarefied corporate territory.

But inside the company, Gwynne Shotwell, SpaceX’s president and chief operating officer, has long been regarded as a stabilizing force and a key architect of its growth. Current and former associates have credited her with translating Musk’s ambitions into operational discipline, helping build the business into a company broad enough to command both aerospace prestige and A.I. investor enthusiasm.

That success, however, has not quieted governance concerns. Public filings cited by Reuters showed that Musk retains about 85.1 percent of SpaceX’s voting power, a level of control that some large pension officials have criticized as unusually favorable to management. For many investors, the structure is a familiar trade-off in Musk-led companies: access to an audacious growth story, paired with limited influence over how it is run.

Risks beyond the stock chart

The company’s soaring valuation is arriving as legal and political questions remain in the background. The Justice Department recently asked a federal court in Mississippi to dismiss an NAACP-backed lawsuit over air pollution tied to xAI data-center operations now owned by SpaceX. The case is separate from the company’s stock market performance, but it highlights the broader scrutiny facing Musk’s constellation of businesses as they expand in energy-intensive areas such as A.I. infrastructure.

The Cursor acquisition brings its own uncertainties. SpaceX is paying a premium price for a fast-growing company in an unforgiving sector, and investors will be watching whether it can integrate a beloved developer product without diluting the independence that helped make it valuable. They will also want evidence that the purchase does more than add a fashionable asset — that it materially improves SpaceX’s position against better-established A.I. rivals.

For now, though, the market is focused less on integration risk than on possibility. In less than a week, SpaceX has moved from being a long-awaited listing to one of the market’s central obsessions — a company whose shares are climbing on ambition, scarcity and momentum, and whose swollen valuation is already beginning to change what it can buy, build and promise.
