SpaceX Forecasts $35–$40 Billion in Fourth-Quarter Capital Spending

SpaceX forecast $35 billion to $40 billion in fourth-quarter 2026 capital expenditures, nearly double its $19.6 billion outlay in the third quarter, as it expands AI computing infrastructure. The investment could accelerate revenue growth, but returns depend on bringing new capacity online and monetizing it.

Why does the spending matter to investors?

SpaceX reported $7.6 billion in third-quarter AI revenue, exceeding Starlink's $5.2 billion. More computing capacity could support further growth, but the investment requires substantial upfront capital and successful deployment.

Can SpaceX recover its AI infrastructure investment quickly?

CFO Bret Johnsen said new computing deployments were generating payback in less than a year at current pricing. This is management's estimate, not a guarantee that every investment will achieve that return.

Could the spending pressure SpaceX's profitability?

Yes, if costs rise faster than revenue or new infrastructure takes longer to monetize than expected. SpaceX reported $4.4 billion in third-quarter net income, but its CFO expected fourth-quarter gross margins to be more consistent with the second quarter because some third-quarter customer-mix benefits were one-time effects.

What should investors watch next?

Investors should watch whether the new computing capacity comes online as planned, whether AI customers convert demand into revenue, and whether returns justify the higher capital spending. SpaceX also forecast fourth-quarter 2026 capital expenditures of $35 billion to $40 billion, making execution and cash generation important indicators.
