What's Going on with SpaceX Stock?

Space Exploration Technologies (NASDAQ: SPCX) stock has been on a wild ride.

After debuting at $135 a share, it surged to roughly $225 before falling to around $105. It has since recovered to about $140 (as of this writing). That's a remarkable swing for a company whose long-term story hasn't changed dramatically in just a few weeks. So, what's going on?

Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »

I think three things explain most of the volatility: Expectations have gotten ahead of reality, SpaceX's enormous spending has raised new questions, and investors are increasingly focused on Starship.

The first problem was simply how quickly enthusiasm built around the stock . SpaceX went public with enormous investor interest. That's hardly surprising. Few companies have a combination of technological ambition, growth, and Elon Musk's track record.

But excitement can become dangerous when it gets embedded in the share price. SpaceX quickly climbed from its $135 IPO price to roughly $225. To put that into perspective, the market capitalization at the peak was close to $3 trillion, making it one of the five largest companies on the planet.

At that level, investors weren't merely betting that SpaceX would execute well. They were betting it would execute exceptionally well. That's an important distinction. When a stock is priced for near-perfect execution, even excellent results can disappoint if they aren't quite good enough.

And SpaceX's first earnings report provided a perfect example. Revenue jumped 92% year over year to approximately $7.8 billion. That's fantastic. Still, it didn't stop the stock from correcting by more than 50% from its peak at one point.

But investors also discovered just how much money SpaceX is spending to build its future, which brings us to the second issue.

SpaceX is spending billions to build the future

SpaceX spent approximately $18.4 billion on capital expenditures during the second quarter. Put that number in perspective. The company generated $7.8 billion of revenue while spending more than twice that amount on capital investment. The vast majority went toward AI infrastructure, accounting for $15.8 billion. That's an enormous bet. But it isn't necessarily a bad one.

SpaceX's AI-related revenue surged 247% year over year to approximately $2.6 billion. The company also turned the AI segment's adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) positive during the quarter. In other words, SpaceX isn't simply spending billions on an idea with no customers. It's building infrastructure for a rapidly growing business.
