SpaceX Stock Down Double Digits Following First Public Earnings

SpaceX’s debut as a public company delivered a resounding revenue beat and sharply narrower losses, yet the stock is down 11.7% in pre-market trading as markets questioned whether the results justify the aerospace giant’s trillion-dollar-plus valuation amid massive ongoing cash burn.

The SpaceX stock price (NASDAQ:SPCX) has fallen 11.7% to $11.62 in pre-market trading, after rallying 9.43% on Tuesday heading into the earnings release, setting up what a classic “buy the rumour, sell the news” dynamic. The sharp reversal comes despite what would normally be considered exceptional results for a newly public technology company, suggesting markets had priced in near-perfection ahead of the print.

The Print

SpaceX reported second-quarter revenue of $7.8 billion, up 92% year-over-year and comfortably ahead of the $6.93 billion consensus estimate, representing a 13% beat. The company posted an adjusted loss per share of $0.09, significantly narrower than the expected $0.26 loss, while adjusted EBITDA surged 191% to $3.5 billion versus estimates of $2.03 billion, a 72% beat on the profitability metric.

Net income came in at a loss of $541 million, well ahead of the anticipated $1.94 billion loss, demonstrating rapid operational leverage as the company scales its three core business segments: launch services, Starlink connectivity, and artificial intelligence infrastructure.

The connectivity division, anchored by the Starlink satellite internet service, generated $4.3 billion in revenue, up 66% year-over-year, as subscriber counts doubled to 12 million users globally. However, average revenue per user fell 22% to approximately $66 per month, reflecting the company’s aggressive international expansion into lower-priced markets and the introduction of more affordable service tiers.

SpaceX’s nascent AI segment posted the fastest growth, with revenue surging 247% to $2.6 billion as the company ramped compute capacity for its xAI subsidiary and related ventures. Management disclosed that the company invested approximately $15.8 billion in AI infrastructure during the quarter alone, more than tripling compute capacity to roughly 1.4 gigawatts.

The Cash Flow Challenge

While the headline numbers impressed, a deeper dive into SpaceX’s cash dynamics reveals why markets reacted negatively. According to detailed breakdowns circulating in investor communities, the company generated approximately $3.5 billion in operating cash flow during the first half of 2026 but deployed roughly $28.5 billion in capital expenditures over the same period, resulting in negative free cash flow of approximately $25 billion on an annualized basis.

The massive capital intensity stems primarily from three sources: ongoing Starlink satellite deployment and ground infrastructure, the Starship development programme, and the rapid build-out of AI training and inference capacity. For a company still posting net losses and now subject to quarterly public-market scrutiny, that level of cash consumption has proven difficult for markets to digest at current valuation levels.

The Starlink ARPU decline, while partially explained by geographic mix, has emerged as a particular concern. If the company cannot maintain pricing power as it scales, or if competitive pressure from emerging low-Earth-orbit constellations intensifies, the unit economics that underpin most bullish valuation models could deteriorate significantly. Some analysts had modelled Starlink ARPU stabilising or even rising as the service matured; instead, it fell more than 20% year-over-year.

The AI Wild Card

SpaceX’s aggressive push into artificial intelligence represents both the company’s greatest opportunity and its largest question mark. The $2.6 billion in quarterly AI revenue sounds impressive in isolation, but it remains unclear how much of that figure represents sustainable, high-margin business versus lower-margin infrastructure sales or intra-company transfers related to xAI and other Musk ventures.

More concerning for near-term sentiment, the AI segment appears to be the primary driver of capital intensity, with the company pouring billions into compute infrastructure at a time when broader technology markets are beginning to question the return on investment for massive AI spending. While Musk has publicly framed the AI investment as accelerating SpaceX’s path toward potential trillion-dollar annual revenue by 2030, that timeline requires near-flawless execution and assumes AI monetisation at scale, neither of which is guaranteed.

Technical Pressures and Lock-Up Concerns

Beyond fundamentals, technical factors are exacerbating Monday’s decline. A significant share lock-up expiration is scheduled for later this week, potentially releasing a wave of insider and early investor selling. Markets typically front-run such events, with traders choosing to de-risk ahead of anticipated supply rather than waiting for forced repricing when restrictions lift.

Additionally, SpaceX has attracted enormous interest from retail investors and levered products, including multiple 2x and 3x single-stock ETFs that have proliferated since the IPO. These vehicles tend to amplify volatility in both directions, and when momentum reverses, mechanical rebalancing can create self-reinforcing selling pressure independent of fundamental views.

The combination of crowded positioning, leverage, and an imminent lock-up expiration creates a perfect storm for near-term volatility, even if long-term investors remain convinced of SpaceX’s potential.

What Next For SPCX?

SpaceX’s first earnings report as a public company delivered strong operational results that would satisfy most investors under normal circumstances. Revenue growth of 92%, EBITDA expansion of 191%, and a net loss significantly narrower than expected all point to a company scaling rapidly and improving its cost structure.

Yet the market’s harsh reaction underscores a fundamental truth: at a $1.7 trillion valuation, “good” is not good enough. Markets had priced in not merely growth, but a swift path to profitability and cash generation that would justify the premium multiple. Instead, they received confirmation that SpaceX remains in heavy investment mode, with tens of billions in annual capital expenditure and an AI strategy that, while promising, is largely unproven from a profitability standpoint.

The Starlink ARPU decline, while explainable, introduces uncertainty into what has been the most reliable pillar of the bull case. If connectivity margins compress as the company chases volume in lower-priced international markets, the business may evolve into more of a utility than the high-margin platform some had envisioned.
