SpaceX held $89.9 billion in cash and securities on September 30. Less than a month later, it committed to rent its next batch of chips rather than buy them.

The deal totals about $40 billion over roughly five years. On the same date, SpaceX reported $38.0 billion of debt. The filing is short. What it leaves out matters more than what it says.

What did SpaceX actually sign?

SpaceX signed a binding commitment letter on October 24. It promises to sign a lease later. SpaceX has not signed the lease itself.

According to its October 26 filing with the SEC, an Apollo Global Management entity will buy graphics processing unit pods and related equipment. It will then lease them to SpaceX for data centers that SpaceX picks. The equipment arrives in batches. Each batch gets its own schedule of about five to five and a quarter years.

The filing expects the lease to close before year end and the schedules to start in the first half of 2027. It also warns the deal "may not close on the anticipated terms or timeline, or at all."

Is this debt or a lease?

On paper, it is a lease. Early reports described bank loans and bonds, and the filing uses neither word.

On October 6, Reuters reported that SpaceX was in talks to raise $40 billion for Nvidia chips. One source said the plan was about $10 billion in bank loans and $30 billion in investment-grade debt, with Apollo expected to lead. The filing never mentions loans, bonds or the chip maker. It describes the purchase only as graphics processing unit pods and related equipment.

Both accounts can be true. A lessor may borrow money to buy the equipment it leases, and the filing does not say how Apollo's entity pays for the chips. TechCrunch quotes SpaceX's chief financial officer, Bret Johnsen, saying the lease "diversifies our funding sources."

The funding need is real. In the first nine months of 2026, SpaceX spent $48.1 billion on property and equipment, according to its quarterly report. Its operations produced $13.1 billion over the same period. Outside money covered the gap. Third-quarter spending alone reached $19.6 billion, up from $6.9 billion a year earlier. At that pace, the lease's $40 billion in principal equals about two quarters of spending.

Does a lease put the chip risk on Apollo?

Not necessarily. The filing's own rent formula points the other way: SpaceX repays the full cost of the equipment plus interest.

Each quarter, rent equals one-twentieth of the financed cost, plus a fixed rate on what is still owed. Twenty quarters of one-twentieth add up to the whole price. The schedules run about 20 to 21 quarters.

Here is a simple example. Say one batch of chips costs $1 billion. SpaceX would owe $50 million of that cost each quarter, plus interest on whatever remains. After five years, it would have paid back the full $1 billion. The numbers are illustrations. The filing gives no price for any batch.

My read: Apollo's entity holds the title, but SpaceX pays back what the entity spends. "Finance lease" is an accounting label that generally signals the tenant carries most of the cost of owning the asset. SpaceX already reports finance leases. The liability was $983 million on September 30. This plan is about 40 times larger.

That is a reading of the formula, not a statement from the filing. Whether SpaceX can buy or keep the chips at the end is exactly what the filing does not say.
