Alphabet’s future funding and financial support commitments to entities it does not consolidate were $31.9 billion on 30 September, against $1.1 billion at the end of 2025, according to its third-quarter Form 10-Q. That is 29 times the year-end figure, by our arithmetic.
The filing says the total includes “$20.0 billion of future capital funding commitments with a private company contingent upon the achievement of specified operational and financial milestones through 2030” and $10.0 billion of potential backstops for the Crux AI joint venture.
Short explainer · Alphabet’s 10-Q: $128.2B in Private Stakes, $31.9B in Pledges
Business Pill · FINANCIAL CONDITIONS
A short explainer on financial conditions. It teaches the general idea only and says nothing about Alphabet.
The key insight: Alphabet’s commitments to fund or support entities it does not consolidate rose to $31.9 billion on 30 September from $1.1 billion at year-end, 29 times by our arithmetic, including $20.0 billion of milestone-based funding for an unnamed private company and $10.0 billion of Crux AI backstops.
The note on variable interest entities says these are entities where Alphabet holds an interest but is not the primary beneficiary, so they stay off its consolidated statements. It lists investments in private companies and renewable energy entities, leases and credit derivatives with data center entities, and financial guarantees with energy infrastructure entities.
The derivatives table shows the notional amount of equity derivatives at $21.1 billion on 30 September, against zero at year-end. The 10-Q says those notional amounts “primarily represent an agreement for future capital funding in the form of notes receivable or equity to be funded in multiple tranches contingent upon the achievement of specified operational and financial milestones through 2030”.

From $30 Billion to $20 Billion
Our earlier report on Alphabet’s stake swings noted that the first-quarter 10-Q described a $40.0 billion commitment to a private company in March 2026: $10.0 billion of capital plus $30.0 billion of future funding contingent on milestones. The third-quarter filing gives $20.0 billion for the contingent part, $10.0 billion lower, by our arithmetic. The third-quarter 10-Q does not name the company.
The Crux AI Backstop
The 10-Q says Alphabet agreed with Blackstone in May 2026 to form a joint venture providing data center capacity, operations, networking, hardware and software as one compute-as-a-service offering. Blackstone committed up to $5.0 billion of capital; Alphabet committed backstops of up to $10.0 billion. In the third quarter the venture was named Crux AI and signed a multi-year commercial agreement with Alphabet.
The Wider Off-Book Stack
Separately, the filing lists $75.7 billion of contingent backstop obligations for data centers, of which $48.0 billion is executed with third-party providers, and $22.8 billion of financial guarantees for equipment behind power agreements; we covered those in our report on Alphabet’s data center backstops. Credit derivative notional rose to $48.0 billion from $16.9 billion at year-end.
The 10-Q also gives $130.5 billion of data center and energy leases that “have not yet commenced”, covered in our report on Alphabet’s commitments. On TPU systems sold to customers, it says contracts “may also include options requiring us to repurchase the hardware and embedded software at pre-set prices, over a multi-year term”; we covered the TPU inventory build in our report on Google’s TPU customers.
The Business Lever: Support Promises That Sit Outside the Balance Sheet
As we read the note, Alphabet is promising money to outside entities, a private company on milestones and a data center venture through backstops, in forms that are disclosed in notes rather than recorded as liabilities. The filing says maximum exposure is generally limited to the carrying value plus these future funding and support commitments.
The Structural Read
As we read the note, Alphabet is extending support to outside entities in forms that sit in footnotes rather than on its balance sheet as liabilities.
As we read the third-quarter 10-Q against our earlier reporting, the milestone-contingent part of the private-company commitment is $10.0 billion lower than the $30.0 billion described in March, and the third-quarter filing does not say why.
As we read the Crux AI terms, Blackstone supplies up to $5.0 billion of capital while Alphabet promises up to $10.0 billion of backstops for agreements the venture may sign.

“primarily represent an agreement for future capital funding in the form of notes receivable or equity to be funded in multiple tranches contingent upon the achievement of specified operational and financial milestones through 2030”
Three Implications
FOR ALPHABET’S RISK The 10-Q says maximum exposure to these entities is generally limited to the carrying value plus future funding and financial support commitments.
FOR THE DATA CENTER STACK The filing also lists $75.7 billion of contingent data center backstops and $130.5 billion of leases that have not yet commenced.
FOR WHAT IS STILL UNKNOWN The 10-Q does not name the private company or say which milestones have been met.
The framework argues: “The $1T capex cycle is being underwritten by a $1T concentrated demand commitment from two counterparties whose combined free cash flow is deeply negative.”
As we read it, Alphabet’s milestone funding and backstops are one way a supplier supports that demand off its own balance sheet. The framework predates this filing and does not discuss it.
What Is Not Established
The 10-Q does not name the private company, does not say which milestones have been met or why the contingent amount is $10.0 billion lower than in the first quarter, and does not say whether any Crux AI backstop has been drawn. Whether the TPU repurchase options have been exercised is not stated.
This Week In The AI Supercycle
Execution Fault Lines, Concentrated Demand, and Geopolitical Firewalls
This week’s issue: the AI build is not short of demand for its parts. It is short of cheap money, and its end revenue rests on a narrow base of large, often venture-funded buyers.
Alphabet’s commitments to fund or support entities it does not consolidate reached $31.9 billion on 30 September, 29 times the year-end figure by our arithmetic. The 10-Q puts $20.0 billion of it in milestone-based funding for an unnamed private company through 2030 and $10.0 billion in backstops for Crux AI, its joint venture with Blackstone.
A note on sourcing. All figures are from Alphabet’s Form 10-Q for the quarter ended 30 September 2026, read on 31 October; the first-quarter commitment figure is from our earlier reporting on Alphabet’s first-quarter 10-Q. Figures labelled our arithmetic are our own.
