Big Tech's capex spending looks different this year as Meta and Tesla save for later

When will investors see returns on all that AI spending? That's the nagging question facing tech companies quarter after quarter. The AI build-out sounds nice, but shareholders are craving returns on those investments.

The easiest way to improve margins, as any corporate consultant knows, is to watch spending. And in high-rate environments, spending less and showing financial discipline is rewarded even more.

Meta ( META ), Tesla ( TSLA ), and SpaceX ( SPCX ) did that for their near-term outlooks, which undershot expectations. That looks different, and welcome.

But it was short-lived: The costs were just moved to a different spot on the timeline.

Longer-term, off-balance-sheet spending plans of $825 billion for Meta and a $100 billion chip plant estimate for Tesla upended all the goodwill on Thursday — sending markets into a tizzy.

A gauge of Meta's credit risk surged to a new record and its bonds sank, Bloomberg reported, after the company said it would spend about $825 billion in the future on computing power, AI infrastructure, and other commitments.

Meanwhile, Elon Musk said the chip plant Tesla is building with SpaceX will need tens of billions of dollars in equipment through early 2028 and likely more than $100 billion over the long term.

Scaling robots and robotaxis, reusable rockets, and putting data centers in space are things that these companies do not currently do. So it should come as no surprise that it's going to be expensive. After all, that brief list probably has some of the most expensive-sounding things a person could conceive.

The bigger truth of these expenses, however, is that they're not yet on balance sheets and represent hopes for massive growth. In other words, hyper-bullish ambition.

Even as these companies showed some pleasingly responsible capex numbers on their latest earnings, Zuckerberg and Musk still need to sell their visions above all else.

All this stands in stark contrast to Apple ( AAPL ) and its tremendous rise this year . The company is sitting on its cash pile and watching its peers pour hundreds of billions of dollars into AI tech, proving the point in reverse. In the absence of meaningful AI profits and plenty of AI volatility, a stable hardware business has become Wall Street's favorite tech hedge.

Wall Street is fickle. And there's a fine line, apparently, between tech companies spending too much or too little on their AI dreams. Sometimes, pulling back on AI investment isn't received as more disciplined corporate finance, but as taking your foot off the gas pedal.
