SpaceX Went Public and Is Spending Billions on AI — Here's the Simple Version
SpaceX's spending on its artificial intelligence unit, called xAI, reached $15.8 billion in the second quarter of 2026. That's up from $7.7 billion the previous 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 xAI's Grok service as "the AI layer" for SpaceX (SpaceX IR.
Capital expenditures, or capex, is the money a company spends on big-ticket items like buildings, equipment, and computer systems. SpaceX's capex on AI jumped 20 times in one year. That puts the company's spending in the same ballpark as the biggest tech companies in the world, like Amazon and Google. The jump from $7.7 billion to $15.8 billion in a single quarter, if kept up for a full year, would mean over $60 billion in annual spending. Goldman Sachs projected in June 2026 that SpaceX's AI revenue will grow from $3.2 billion in 2025 to $322 billion in 2030, about a 100-fold increase (Motley Fool.
SpaceX held its first public stock offering on June 12, 2026, at a value of about $1.77 trillion. By August 4, 2026, the stock had dropped 16% below its $150 opening price, following what Reuters called a meteoric IPO pop — a sharp early rise that then faded (Reuters). Reuters described the company as a "satellites-to-chatbots" business valued at about $1.7 trillion.
The sell-off got worse on August 5 when SpaceX unlocked $101 billion in shares (Bloomberg). When a company goes public, early investors and insiders are usually locked up — they cannot sell their shares for a set period. When that period ends, those shares become available to trade, which can push the price down. At a $1.7 trillion value, $101 billion in newly available shares equals about 6% of the company. That is a lot of new stock hitting the market at once for a share price that had already fallen.
By August 7, 2026, SpaceX shares had bounced back 23%, approaching the $135 IPO price after a $327 billion rally (Bloomberg). The recovery brought the stock near the lower end of its IPO range, though the reporting does not confirm whether shares actually closed at $135.
The broader context here is the gap between what SpaceX is spending and what it is earning. Goldman's $322 billion 2030 revenue estimate, if taken at face value, means the AI division alone would bring in more money than most companies in the S&P 500 are worth today. Whether that projection comes from detailed analysis or simply projecting early growth rates forward is not clear from the available sources. What is known: the spending is real and growing fast, the revenue is $3.2 billion today, and the difference is being funded at a $1.7 trillion valuation right after a public debut that has already tested investors' resolve.
The stock's wild ride after the IPO — down 16%, then up 23% — shows what happens when a large company with many insider shareholders enters the public market. The $101 billion share unlock caused the drop. The $327 billion recovery suggests buyers stepped in near the IPO price. Whether they keep buying depends on how investors judge the spending against actual revenue growth in future quarterly reports.
One key difference: SpaceX's rocket launch and satellite businesses make money from signed contracts with known economics. The xAI unit's Grok service is described internally as "the AI layer" for the whole company, suggesting it is woven into SpaceX's products rather than standing alone as a chatbot. The $15.8 billion quarterly spending figure shows that whatever that integration looks like, the company is paying top-tier prices to build it. Whether Goldman's 100-fold revenue prediction proves right or not won't be clear for years. For now, the market is valuing a company whose AI spending doubled in a quarter and whose stock has already gone from IPO pop, to drop, to partial recovery in under two months.
