SpaceX (SpaceX (SPCX)) is building one of the biggest AI infrastructure businesses on the planet. But its latest earnings reveal a wrinkle: a huge chunk of that growth is tied to just a couple of customers.
The company's second-quarter filing shows that one customer brought in 18.3% of total revenue across all three operating segments. A second customer, meanwhile, accounted for 19.5% of revenue in the AI segment alone. Combined, those two unnamed clients represent the equivalent of 37.8% of SpaceX's quarterly revenue.
That's a lot of eggs in two baskets. And while SpaceX didn't name either customer, the filing notes that the AI customer was below the 10% reporting threshold a year earlier. In other words, this relationship has become a much bigger deal over the past twelve months.
SpaceX's AI Revenue Relies on a Handful of Customers
These disclosures highlight both the strength and the concentration of SpaceX's AI momentum. Landing multi-billion-dollar cloud agreements has supercharged growth, but it also means a relatively small number of customers now drive a meaningful share of revenue.
Earlier this week, SpaceX revealed it had signed $14.1 billion in contracted cloud services agreements, including a previously undisclosed $6.7 billion contract with a single customer. That reinforces how a handful of large AI clients are shaping the company's near-term financial picture.
For investors, this is a double-edged sword. The growth is impressive, but concentration risk is real. If one of these big customers pulls back or renegotiates, the impact on SpaceX's revenue could be significant. It's a story worth watching as the company continues to scale its AI ambitions.
