Alphabet's $811 Billion AI Bet: Inside the Hidden Obligations Reshaping Big Tech's Balance Sheets

Key findings from Alphabet's Q2 2026 filing and capital-structure moves

The $811 billion in purchase commitments

• These are contracted future spending obligations under supply agreements — not debt on the balance sheet . Bloomberg reports they represent purchases Alphabet has already committed to making, largely tied to AI compute and data center infrastructure .
• The $500 billion quarter-over-quarter increase is the largest single-quarter jump on record for Alphabet, signaling an accelerated AI infrastructure buildout .
• Roughly $200.7 billion of the total were short-term, Alphabet disclosed in its filing .
• Separately, Alphabet also reported $108.2 billion in remaining performance obligations (revenue backlog), primarily for Google Cloud customer contracts .

Capital-structure changes to fund AI infrastructure

• In June 2026, Alphabet announced an ~$85 billion equity raise — its first stock issuance since 2005 — combining a $10 billion private placement to Berkshire Hathaway, a ~$30 billion underwritten public offering, and a $40 billion at-the-market program . The underwritten portion was oversubscribed and ultimately priced at ~$35 billion .
• Alphabet's balance sheet has also been transformed on the debt side: total debt rose from ~$12 billion (essentially unleveraged) to over $100–$102 billion across six currencies in about 18 months . This includes a 100-year Sterling note maturing in 2126 .
• CFO Anat Ashkenazi confirmed the company is funding the AI buildout through a mix of operating cash flow, new debt, and the equity raise .
• Alphabet also raised its 2026 capex guidance to $195–$205 billion , and had already guided 2025 capex to approximately $85 billion . In 2022, capex was roughly $31 billion — meaning 2026 spending is expected to be about six times larger .

Broader industry pattern of off-balance-sheet financing

Alphabet's $811 billion is not an isolated figure — it is part of a much larger industry-wide trend:

• $1.65 trillion in combined future lease and purchase obligations across the top five hyperscalers (Alphabet, Microsoft, Amazon, Meta, Oracle), according to a Nikkei analysis of SEC filings as of July 2026 .
• $662 billion in future data center lease commitments not yet begun — sitting entirely off balance sheets — identified by Moody's Ratings for the same five companies in February 2026 . Moody's also found total undiscounted future lease commitments reached $969 billion across these firms as of end of 2025 .
• $120 billion in AI data center spending already shifted off balance sheets via special-purpose vehicles and joint ventures, per a Financial Times analysis .
• A common structure involves joint ventures and SPVs that acquire or develop data center assets, keeping the debt off the hyperscalers' own balance sheets while private credit firms (e.g., Blue Owl, Apollo) and infrastructure funds provide the capital . An IESE Business School analysis noted roughly in identifiable off-balance-sheet financing among hyperscalers as of mid-2026, with Meta's $27 billion joint venture with Blue Owl for its Hyperion data center campus in Louisiana as a prominent example .
• The Bank for International Settlements (BIS) confirmed that alongside traditional bonds, hyperscalers are increasingly relying on off-balance-sheet arrangements in partnership with private credit firms to finance data center expansions .

The scale of borrowing is also unprecedented: global tech companies issued a record $428.3 billion in bonds through early December 2025 , and the top five hyperscalers alone issued about $121 billion in new debt via bonds in 2025, up from $40 billion in 2020 . Morgan Stanley estimates that tech firms and others may need as much as $800 billion from private credit in asset-backed deals by 2028 .

Alphabet's $811 billion in purchase commitments is thus the single largest disclosed off-balance-sheet obligation among the hyperscalers, but the broader industry total — across both leases and supply contracts — is estimated at $1.65 trillion by Nikkei and at least $662 billion in future lease commitments alone by Moody's. These structures insulate Big Tech's on-balance-sheet credit profiles but concentrate risk among private credit lenders and expose investors to a wave of obligations that most do not fully account for .
