Moody's Warns Alphabet's AI Spending Is Starting to Weigh on Its Credit

Moody's Ratings issued a warning on July 24, 2026, that the AI infrastructure spending surge is threatening credit quality at some of the largest technology companies in the world, including Alphabet (NASDAQ:GOOGL).

The note reframes what many investors view as signs of financial success into a balance-sheet story, arguing that the shift from software-driven profits to hardware-heavy capital spending is creating financial risks that even the most cash-rich companies have not faced before. This is what the warning covers, what Alphabet's latest numbers reveal, and why it matters for your portfolio.

Moody's flagged 'unprecedented' spending across six hyperscalers

Moody's warned in a research note that the transition from asset-light to asset-heavy business models requires unprecedented levels of investment and capital raising, threatening credit quality at six companies it tracks, according to CNBC. The six firms are Microsoft, Amazon, Alphabet, Meta, Oracle, and CoreWeave.

The agency noted that these companies previously relied on software, intellectual property, and scalable cloud services that required modest capital investment. Generative AI has reversed that model by demanding vast physical infrastructure, including warehouses packed with expensive and energy-hungry servers.

Combined capex is projected at $785 billion in 2026 alone

Moody's projects that combined capital expenditures across the six hyperscalers will reach $785 billion in 2026 before climbing to approximately $1 trillion in 2027, as reported by CNBC. The scale of spending breaks a decades-long formula in Silicon Valley, where low-cost software replication yielded enormous margins.

To finance the expansion, technology companies are increasingly turning to Wall Street. The shift has produced booming profits for the financial industry, while the tech companies themselves absorb the burden of building a physical infrastructure layer that rivals anything in modern corporate history.

Direct debt across the six companies has reached $460 billion

Direct debt across the six hyperscalers tracked by Moody's has climbed to approximately $460 billion, according to the same CNBC report. Companies are also raising capital through equity markets and off-balance-sheet financing to fund AI expansion.

Alphabet's long-term debt surged from roughly $11 billion to about $77 billion in approximately 15 months, and the company raised about $85 billion through an equity offering in June 2026, as noted in a Seeking Alpha earnings preview. Your exposure to these stocks means you now own companies with very different capital structures than the ones you originally bought.

Alphabet posted its first negative free cash flow quarter since its IPO

Alphabet's Q2 2026 capital expenditures doubled year over year to $44.9 billion, exceeding the $39.1 billion in operating cash flow the company generated, pushing free cash flow to negative $5.9 billion, as reported by Value Add VC. Revenue still grew 24% to $119.8 billion, and Google Cloud surged 82% to $24.8 billion.

The negative free cash flow quarter was the first since Alphabet's 2004 initial public offering. Trailing-twelve-month free cash flow remains positive at roughly $53 billion, but the quarterly trend has shifted sharply as infrastructure spending accelerates beyond what the business generates in cash.

Alphabet raised its 2026 capex guidance to as much as $205 billion

Alphabet increased its full-year 2026 capital expenditure guidance to a range of $195 billion to $205 billion, up from $180 billion to $190 billion provided the prior quarter, according to CNBC. CFO Anat Ashkenazi warned that free cash flow would remain under pressure. Key Q2 figures include the following.

• Revenue of $119.8 billion, up 24% year over year.
• Google Cloud revenue of $24.8 billion, up 82%.
• Cloud backlog of $514 billion.
• Capital expenditures of $44.9 billion, doubled from a year earlier.
• Free cash flow of negative $5.9 billion.

Off-balance-sheet lease commitments have ballooned to $1.2 trillion

Moody's highlighted a rapidly growing source of financial exposure that receives less investor attention, with off-balance-sheet data center lease commitments across the six hyperscalers ballooning to approximately $1.2 trillion, as reported by BigGo Finance.

These commitments represent real financial obligations stretching years into the future. For you as an investor, the total financial exposure of these companies extends well beyond what the headline debt figures suggest.

Moody's still rates Alphabet at Aa2 with strong credit fundamentals

Moody's and S&P still rate Alphabet's debt at Aa2 and AA+ respectively, indicating no immediate credit risk, as noted in Seeking Alpha's earnings preview. Alphabet holds approximately $240 billion in cash and marketable securities, one of the largest corporate cash reserves anywhere.

Moody's emphasized that Microsoft, Alphabet, Amazon, and Meta maintain some of the strongest corporate balance sheets in the world. The warning is not about imminent financial distress but rather about the direction of travel, and whether these companies' credit profiles may gradually weaken under sustained spending pressure.

Bottom line

Moody's warning represents a warning on even the healthiest credits in the corporate world. Alphabet's revenue is growing at 24%, its cloud business is booming at 82%, and it still holds $240 billion in cash.

The Moody's note is worth reading as a reminder that even a $2 trillion company generating $120 billion in quarterly revenue may need to raise debt and sell stock to fund its ambitions. Knowing when to start investing in or around these companies requires understanding that their capital structures are changing fast.
