If the Tenant Defaults, Google Takes the Data Centre

Key takeaways

Alphabet disclosed 43.8 billion dollars of maximum potential future payments on credit derivatives that backstop data centre payment obligations as of 30 June, on agreements running up to 15 years. If your compute sits in one of those buildings, your cloud vendor is also your landlord's guarantor.
Add the four disclosed lines and Alphabet is carrying about 95.5 billion dollars of contingent commitment: 43.8 billion in credit derivatives, 7.6 billion in financial guarantees, 24.1 billion of further backstops still being negotiated, and 20.0 billion of milestone-linked capital funding through 2030.
The filing does not name a single counterparty. It says 'certain third parties' and 'a private company'. The identification of Anthropic comes from press reporting, not from the disclosure, so treat the two as separate levels of evidence.
Alphabet classifies these instruments as Level 3, meaning it values them with unobservable inputs including its own assumptions about counterparty risk and credit default rates. There is no market price on this exposure, only a model.
On default, Alphabet says it retains the right to assume the underlying leases for internal use or to sublease them. The company that guarantees the rent ends up holding the building, which is the outcome to plan around if you are a tenant in the same market.

What the filing says, in its own words

Alphabet's quarterly report for the period ended 30 June 2026 contains a sentence worth reading twice. As of that date, the company states, it had provided backstops in the form of financial guarantees and credit derivatives with maximum potential amounts of future payments of 7.6 billion dollars and 43.8 billion dollars respectively. The larger figure is the one attached to data centres: Alphabet has entered into agreements with certain third parties to backstop payment obligations relating to data centres, and it accounts for those agreements as credit derivatives.

The mechanics are set out plainly. The notional amounts represent the maximum potential exposure in the event of specified default scenarios by underlying parties. The agreements carry remaining terms of up to 15 years, and the exposure reduces over time as those parties meet their obligations. Alphabet also discloses an agreement to provide an estimated 24.1 billion dollars of further backstops supporting the build-out of data centre and energy supply infrastructure, subject to finalising terms with data centre providers, plus 20.0 billion dollars of future capital funding commitments to a private company, contingent on operational and financial milestones through 2030.

Four commitments, one counterparty problem

The number nobody printed: add the four disclosed lines together and Alphabet is carrying roughly 95.5 billion dollars of contingent commitment tied to compute and the power that feeds it. That sum is our arithmetic, not the company's, and it deserves a caveat: these are four different instruments with four different triggers.

The 7.6 billion dollars of financial guarantees support counterparty procurement of long-lead-time equipment for future power purchase and energy agreements, on terms running through September 2026, and that is a different risk from a 15-year data centre lease. The 24.1 billion dollars is explicitly not yet finalised. The 20.0 billion dollars is equity funding that only flows if milestones are hit, which makes it a commitment Alphabet mostly wants to pay. Summing them is not the same as claiming Alphabet is 95.5 billion dollars in the hole.

What the sum does show is the shape of the thing. This is not one guarantee on one building. It is a programme, spanning leases, equipment procurement, energy supply and equity, pointed at the same corner of the market. The Financial Times reported on 4 August that the wider structure around Alphabet, Broadcom, Apollo, Blackstone and Morgan Stanley amounts to roughly 200 billion dollars of interconnected contracts, with a special-purpose vehicle having bought about 35 billion dollars of hardware in June. The filing is the part of that picture Alphabet has signed its name to.

The filing discloses the exposure but not the tenant

Read the nouns: across the whole document, the counterparties are 'certain third parties', 'underlying parties', 'a private company'. The word Anthropic does not appear anywhere in the filing. Every public identification of who is being backstopped comes from journalism, principally the Financial Times and the Wall Street Journal, not from the disclosure itself.

That is legal and ordinary, and it is also a practical problem for anyone trying to assess the risk. You can see the size of the exposure and its duration. You cannot see how concentrated it is, because you cannot see how many counterparties the 43.8 billion dollars is spread across. A number spread over ten tenants and the same number resting on one tenant are different facts, and the filing does not let you tell them apart.

Level 3 means Alphabet prices this with its own models

Yes, but: the valuation note matters more than the headline figure. Alphabet classifies these credit and equity derivatives within Level 3 of the fair value hierarchy, the tier reserved for instruments with no observable market price. Its stated valuation methods are probability-weighted expected return models drawing on counterparty risk, credit default rates and risk-free rates.

In plain terms, there is no market quoting a price on this exposure. Alphabet estimates what it is worth using assumptions it selects about how likely its counterparties are to fail. That is standard practice and not evidence of anything improper. It does mean the carrying value moves when management's view of counterparty health moves, and an outside reader has no independent way to test the inputs.

What a buyer should ask at the next renewal

The bottom line: the filing tells you what happens if a backstopped party fails. Alphabet retains the right to assume the underlying leases for internal use or to sublease them to third parties, and under certain conditions it may instead extinguish the obligation by making a termination payment. The vendor guaranteeing the rent can end up holding the building.

For a European buyer of cloud or compute capacity, that changes one question at renewal. You already ask where your data sits and under whose law. Add a second: is the capacity I am buying housed in a facility whose obligations my vendor guarantees, and what happens to my contract if that guarantee is called. Alphabet's total purchase commitments and other contractual obligations stood at 811.0 billion dollars at 30 June, of which 200.7 billion dollars was short-term. The buildout is being paid for with commitments, and commitments have counterparties.

Frequently asked questions

Does the 43.8 billion dollar figure mean Alphabet has lost that money?

No. It is a notional amount representing the maximum potential future payments if specified default scenarios occur. Alphabet states the exposure reduces over time as the underlying parties meet their obligations, and that on a default it retains rights over the underlying leases. It is a ceiling on a contingent liability, not a booked loss.

Why does it matter that the filing does not name the counterparty?

Because concentration is the risk that a single number hides. The same 43.8 billion dollars spread across many tenants behaves very differently from the same amount resting on one. Press reporting identifies Anthropic as the beneficiary of the structure, but that identification sits outside the audited disclosure, so it carries a different weight of evidence.

What does Level 3 classification tell a reader?

That the instruments have no observable market price and are valued using unobservable inputs. Alphabet uses probability-weighted expected return models incorporating counterparty risk, credit default rates and risk-free rates. The valuation therefore reflects management's assumptions about counterparty health, and an outside reader cannot independently verify those inputs from the filing.

A vendor that guarantees its customers' rent has taken a credit position on its own demand. Alphabet has disclosed the size and the term of that position, and left the most useful fact, who is on the other side of it, to the newspapers.
