Why Is Space Exploration Technologies Corp. (SPCX) Stock Down -10.21% Today?

Key Takeaways

• SPCX shares tumbled 10.21% to $112.54, wiping out all of the prior session's 9.43% rally and then some.
• The selloff was driven by SpaceX's first-ever quarterly earnings report, which revealed AI-related capital expenditures of $18.4 billion — far above the roughly $13.2 billion analysts had forecast.
• Revenue surged 92% year-over-year to $7.81 billion and the net loss narrowed sharply, but investors focused squarely on the spending trajectory.
• The lockup expiration on August 6, which will release a large tranche of insider shares, added a secondary layer of selling pressure.
• Broader tech sentiment around AI infrastructure spending has soured in recent weeks, amplifying the negative reaction.
• Traders are now watching whether the stock can hold above its IPO price of $135 — a level already breached — and how the lockup unlock will affect liquidity.

Opening Summary

Space Exploration Technologies Corp. — better known as SpaceX — saw its stock SPCX plunge 10.21% on Wednesday, dropping to $112.54 from a prior close of $125.33. The selloff came after the company reported its first quarterly results as a public entity. Despite posting revenue of $7.81 billion that handily beat the $6.93 billion consensus and narrowing its net loss to $541 million from $1 billion a year ago, investors zeroed in on one number: $18.4 billion in capital expenditures for the quarter, with $15.8 billion directed at AI infrastructure alone. The market's verdict was swift and unforgiving, reversing a 9.43% regular-session gain from Tuesday and sending shares deep into negative territory.

Earnings Beat Overshadowed by AI Spending Surge

SpaceX's Q2 2026 report was, by most conventional measures, a strong debut. Revenue grew 92% year-over-year to $7.81 billion. The net loss narrowed to $541 million, or $0.09 per share, significantly better than the $0.26 loss analysts had projected. Adjusted EBITDA nearly tripled to $3.5 billion. All three business segments — Space, Connectivity, and AI — posted revenue above consensus estimates.

Yet none of that mattered once investors digested the capital expenditure line. The company spent $18.37 billion in Q2, more than double the prior quarter and roughly $5 billion above the Street's expectation of $13.22 billion. Of that, $15.83 billion flowed into AI compute infrastructure — a figure that dwarfed the $7.7 billion spent in Q1 and the $749 million spent a year earlier. For context, that single-quarter AI spend exceeded what most large-cap tech firms allocate to AI over an entire year.

CFO Bret Johnsen indicated on the earnings call that capex for the next two quarters would remain at similar levels. With total AI capex for the first half of 2026 already reaching $23.55 billion — versus just $3.32 billion in the same period last year — the spending trajectory has alarmed investors still waiting for AI investments across the tech sector to generate clear returns.

Lockup Expiration Adds Supply Overhang

Compounding the earnings-driven selloff is a major structural event: SpaceX's insider lockup period begins to partially expire on August 6, just two trading days after the earnings release. The unlock could release a significant volume of shares held by pre-IPO investors and employees — estimated at roughly three times the current public float — into the market. With the stock already trading well below its $135 IPO price and down roughly 50% from its post-IPO peak near $225, the prospect of additional selling pressure has unsettled an already fragile shareholder base. A larger tranche of roughly 900 million shares becomes eligible for sale after Q3 results later this year, representing a block larger than the entire IPO issuance.

AI Ambitions Meet Market Skepticism

The earnings report also highlighted Elon Musk's aggressive vision for SpaceX's AI business, which includes the xAI integration, the Grok chatbot, the X platform, and an expanding network of terrestrial and orbital data centers. Musk announced an exclusive chip-supply partnership with NVDA, declaring that SpaceX would build future AI services entirely on Nvidia's Vera Rubin GPU architecture. The Starmind AI-1 payload, co-designed with Nvidia, aims to put "datacenter-class compute" into orbit.

Musk projected that SpaceX could reach a $100 billion annualized revenue run rate by December 2026 and pulled forward the $1 trillion revenue target to 2030. But with the AI segment still posting a $1.26 billion operating loss — even as revenue surged 247% to $2.56 billion — the market is increasingly demanding proof that these colossal investments will pay off. JPMorgan analyst Doug Anmuth noted that capex of nearly $200 billion annually in both 2027 and 2028 could further pressure free cash flow, echoing a trend seen across major hyperscalers.

Market Context and Trading Activity

The decline in SPCX fits a broader pattern of investor fatigue with AI-related capital spending. In recent weeks, heavy AI expenditure from META, GOOGL, MSFT, and AMZN has triggered similar post-earnings selloffs. Tuesday saw a broad market rally that lifted SPCX more than 9% during the regular session, but those gains evaporated entirely after the earnings release. Wednesday's trading reflected a market reassessing the risk-reward profile of one of the most expensive and ambitious companies ever to go public. With a market capitalization still around $1.5 trillion, SpaceX remains valued like a mature tech giant despite generating only a fraction of the revenue and no net profit.

What Comes Next for SPCX

The immediate focus for SPCX traders is the August 6 lockup expiration and how much selling pressure materializes from insiders. Beyond that, the company's Starlink business — the only profitable segment, with $1.66 billion in operating income — remains the financial backbone while the AI and Space divisions burn cash. Upcoming Starship test flights, including a potential first-ever tower catch of the upper stage on Flight 14, could provide positive catalysts. However, the third-quarter earnings report later this year, which triggers an even larger share unlock, looms as the next major risk event. Musk's ambitious targets — $100 billion ARR by year-end, $1 trillion in revenue by 2030 — will face continuous scrutiny as quarterly results either validate or undermine the extraordinary valuation.
