SpaceX's AI Spending Doubled in a Quarter — Here's What That Means for the Stock

SpaceX's capital spending tied to its xAI unit, which runs the Grok AI service, hit $15.8 billion in the second quarter of 2026, up from $7.7 billion in the first quarter and $749 million a year earlier, according to figures reported August 5, 2026 (Yahoo Finance). The company's own investor-relations Q&A page describes Grok as "the AI layer" for SpaceX (SpaceX IR.

Capital expenditures — the money a company spends on physical assets like data centers, chips, and infrastructure — are climbing at a pace that puts SpaceX in the same league as the largest tech companies building AI at scale. A 20-fold year-over-year increase in quarterly AI spending, from $749 million to $15.8 billion, matches the kind of commitments typically seen from hyperscalers like Amazon, Google, and Microsoft. The jump from $7.7 billion to $15.8 billion in a single quarter implies an annualized pace above $60 billion if maintained. Goldman Sachs projected in June 2026 that SpaceX's AI division revenue will grow from $3.2 billion in 2025 to $322 billion in 2030, roughly a 100-fold increase (Motley Fool).

SpaceX held its initial public offering on June 12, 2026, at a valuation of approximately $1.77 trillion. By August 4, 2026, shares had fallen 16% below their $150 initial opening price, following what Reuters described as a meteoric IPO pop (Reuters). Reuters characterized the company at that point as a "satellites-to-chatbots" concern valued at roughly $1.7 trillion.

The sell-off intensified on August 5 when SpaceX unlocked $101 billion in shares, adding downward pressure on a stock already trading below its IPO price (Bloomberg). Share unlocks happen when lockup periods expire, releasing insider and early-investor holdings into the market. At a $1.7 trillion valuation, $101 billion in newly unlocked equity equals about 6% of the company's market capitalization — a meaningful wave of supply for a stock that had already given up its post-IPO gains.

By August 7, 2026, SpaceX shares had rallied 23% and were approaching their $135 IPO price after staging a $327 billion recovery (Bloomberg). The rebound brought the stock back near the lower end of its IPO reference range, though the reporting does not confirm whether shares reclaimed $135 on a closing basis.

The broader context here is the tension between SpaceX's capital intensity and the revenue projections underpinning its AI valuation. Goldman's $322 billion 2030 revenue estimate, if taken at face value, implies the AI division alone would generate more revenue than the current market capitalization of most S&P 500 companies. Whether that projection comes from detailed unit economics or extrapolated adoption curves is not disclosed in the available sourcing. What is known: the capex is real and accelerating, the revenue is at $3.2 billion today, and the gap between the two is being financed at a $1.7 trillion valuation shortly after a public debut that has already tested investor conviction.

The share-price swings in the weeks after the IPO — a 16% decline followed by a 23% rebound — reflect the mechanics of absorbing a large, multi-business company with significant insider share overhang into the public market. The $101 billion unlock was the primary driver of the drawdown; the $327 billion recovery suggests buyers stepped in near the IPO price. Whether that support holds depends on how investors weigh the spending trajectory against actual revenue growth in xAI's future quarterly disclosures.

One distinction worth tracking: SpaceX's launch and satellite businesses generate tangible, contract-backed revenue with established economics. The xAI unit's Grok service is described internally as "the AI layer" for the broader enterprise, suggesting integration across SpaceX's product stack rather than a standalone chatbot. The $15.8 billion quarterly capex figure indicates that whatever that integration looks like, the company is spending at hyperscaler scale to build it. Whether Goldman's 100-fold revenue projection proves directionally correct or another sell-side extrapolation won't be answerable for years. In the interim, the market is pricing a company whose AI spending doubled in a quarter and whose shares have already completed a full round-trip from IPO pop to drawdown to partial recovery in under two months.
