SpaceX's AI Capex Surge Dents Growth Enthusiasm, Stock Slides Despite 92% Revenue Jump

SpaceX's Q2 Revenue Soars but AI Spending Overshadows Results

SpaceX, now a publicly traded company, more than doubled its year-on-year revenue in the second quarter, reporting $7.81 billion—a 92% surge that beat forecasts. Net losses shrank to $541 million from over $1 billion a year earlier, while adjusted EBITDA jumped 191% to $3.5 billion. Yet the numbers failed to satisfy investors.

The culprit was a staggering capital expenditure of $18.4 billion for the quarter, nearly $16 billion of which went to AI computing infrastructure, far exceeding the $13.2 billion analysts expected and the $10.1 billion spent in Q1. This spending spree follows SpaceX’s February absorption of xAI, Elon Musk’s AI startup, and has pushed the company into the kind of AI arms race that markets have recently punished. As a result, after a 9% regular-session gain, SpaceX shares fell more than 8% in early Nasdaq trading, hovering around $115—almost 50% below their all-time high of $225 and well below the $135 IPO price.

During the earnings call, Musk unveiled an accelerated revenue target of $1 trillion by 2030, a year earlier than pre-IPO guidance, and floated a possible 2029 threshold. CFO Bret Johnsen said annualized revenue run rate would hit $100 billion by year-end, partly thanks to the $60 billion acquisition of Cursor, SpaceX’s largest deal ever. Starlink revenue reached $4.29 billion with an operating profit of $1.65 billion, and its subscriber base doubled to 12 million. AI segment revenue soared 247% to $2.6 billion, driven by cloud hosting agreements with Google and Anthropic. Rocket revenue edged up 28% to $962 million, while Musk predicted Starship launches could happen at least once a day “probably within a year.”

Why the Market Punished SpaceX's AI-Heavy Capex

The AI Spending Dilemma for SpaceX vs Big Tech

SpaceX’s blowout capex dwarfs even the most aggressive Big Tech AI budgets relative to revenue. While Alphabet and Meta can fund their AI investments with cash from mature advertising and cloud businesses, SpaceX’s cash outflow is more than double its income. The market’s harsh reaction echoes the selloffs that hit Alphabet and Tesla on heavy AI spending. Yet SpaceX’s situation is starker: it is spending like a startup, but its $7.8 billion in quarterly revenue does not yet cover the bill, raising questions about future dilution or debt. Musk is betting that the massive compute capacity—up to 1.4 gigawatts from 400 megawatts a year ago—will pay off through cloud deals and the Grok subscription model, but near-term cash flow is clearly strained.

Starlink’s Growth and Musk’s Grand Promises

Starlink added 1.7 million customers in the quarter and signed major airline deals with American, Southwest, and others, but the division’s operating profit of $1.65 billion is a fraction of the $18.4 billion spent group-wide. Musk’s forecast that Starlink will provide most of the world’s internet connectivity in less than a decade and that its upcoming mobile service will poach subscribers from AT&T, Verizon, and T-Mobile is an extraordinary claim. For that to materialize, the service must overcome significant regulatory and infrastructure hurdles, and investors will watch closely whether subscriber additions can generate the cash needed to sustain the AI investment without crippling the balance sheet.

Upcoming Lock-Up Expiry Adds to Volatility

Compounding the stock pressure, 911 million previously restricted shares become eligible for sale tomorrow, lifting the free float to 12% of the company. Such a large potential sell-off right after a disappointing earnings reaction adds short-term uncertainty. If insiders or early backers choose to offload shares, the stock could test new lows, further distancing Musk from the billionaire club he briefly touched when SpaceX’s valuation soared.

What SpaceX's Outsize Spending Means for Investors and Rivals

• For existing shareholders: Brace for potential dilution and stock price swings as 911 million shares unlock; consider how much of your conviction rests on Musk’s $1 trillion 2030 target versus the company’s current negative cash flow.
• For telecom investors: Starlink’s mobile service, slated for late 2027, is a direct threat to AT&T, Verizon, and T-Mobile. Monitor subscriber migration patterns and any regulatory pushback that could delay or limit the satellite offering.
• For cloud and AI rivals: SpaceX’s $6.7 billion in new cloud service agreements for the second half and the Cursor acquisition signal deepening competition in hosted AI. The exclusive NVIDIA chip commitment may pressure smaller competitors on supply; watch for margin impacts across the sector.
• For potential SpaceX customers: If you depend on compute or bandwidth for AI workloads, SpaceX’s rapid capacity expansion could offer an alternative to hyperscalers, but pricing sustainability is uncertain given the company’s aggressive spending.
