SpaceX AI spending unnerves Wall Street despite promising quick payoff

SpaceX shares fell after the company reported high capital expenditures driven by a massive investment in AI infrastructure. Despite executive claims of a quick return on investment through compute capacity sales, investors remain skeptical of the spending levels.
Why it matters
The market's reaction underscores the high-stakes nature of the current AI arms race and the pressure on tech companies to prove the profitability of their infrastructure spending.
After SpaceX spent way more on its AI buildout than analysts expected, executives tried to convince investors on Tuesday that it's all worthwhile, claiming that the company is making its money back within a year.
The message didn't resonate, as SpaceX shares sank following the company's first earnings report since its IPO in June. While revenue in the second quarter sailed past estimates, jumping 92% from a year prior, capital expenditures soared over sixfold to $18.4 billion, more than double total sales for the quarter.
Well over 80% of SpaceX's capex went towards artificial intelligence, where the company is way behind OpenAI, Anthropic and Google when it comes to models and services, and where it's now trying to compete against cloud giants Microsoft , Amazon and Google by selling compute capacity.
