Alphabet's $25 billion bond sale lifts 10-year yield to 4.65%

Alphabet's $25 billion bond issuance is testing investor appetite for AI-fueled debt as its capex surge triggers the first negative free cash flow quarter since its IPO.

Ten-year Treasury yields rose to 4.65 percent as Alphabet's $25 billion bond sale tested AI debt appetite after its first negative free cash flow quarter. The offering, split into 10 tranches spanning 2 to 40 years, carries an initial price guidance of about 155 basis points over Treasuries on the longest maturity.

The Financial Times reported Fed Chair Kevin Warsh is prepared to raise rates at the September meeting if inflation data runs hot, a stance that compounds pressure on short-dated Treasuries as the market prices about 15 basis points of a September hike. Treasury yields rose 3 to 4 basis points across the curve, with 2s10s and 5s30s spreads widening to session wides.

The issuance follows Alphabet's decision to raise its 2026 capital expenditure forecast to as much as $205 billion, more than double 2025 spending. The company posted negative free cash flow of $5.86 billion in the second quarter, a 210 percent year-over-year deterioration, as quarterly capital expenditure hit $44.9 billion. Long-term debt nearly doubled to $98.2 billion, the share buyback program was suspended, and interest expense rose almost fivefold.

The deal tests whether bond investors will absorb the wave of AI infrastructure debt. Since 2025, big tech companies have raised more than $350 billion through bond markets, with Alphabet and Amazon leading. A BlackRock-affiliated entity's $12.5 billion bond sale for Meta's Texas data center project saw weak initial demand, and Amazon's related issuance also drew tepid subscription interest.

AI Bond Demand Shows Cracks

The cooling reception for AI-related debt extends beyond Alphabet. SpaceX and other companies that issued AI-linked bonds have seen secondary market spreads widen. Alphabet alone issued more than $50 billion in bonds during the first half of 2026 across Swiss franc, pound, euro, Canadian dollar, and yen denominations, and completed an approximately $85 billion equity offering about two months ago.

The company also filed to issue up to $40 billion in additional A and C class shares, further expanding its capital reserves to fund AI infrastructure expansion. CEO Sundar Pichai told analysts that the dynamics around AI infrastructure "look healthier than where we were about a year ago," even as the balance sheet strain mounts.

Balance Sheet Strain vs. Cloud Momentum

Alphabet still maintains $144 billion in net cash and exited the quarter with an operating net income annual run rate above $160 billion. Google Cloud revenue surged 82 percent year over year to $24.77 billion with a $514 billion backlog, and nearly 90 percent of the Fortune 100 now use Gemini Enterprise.

The broader hyperscaler picture shows no letup. Alphabet, Amazon, Meta, and Microsoft are tracking toward roughly $725 billion in combined 2026 capital spending, about 77 percent above 2025 levels. Amazon raised its 2026 cash capex guidance to about $220 billion, while Meta lifted the low end of its range to $130 billion. Microsoft's ~$175 billion calendar-year figure reflects a lease-accounting reclassification rather than a spending pullback.

For fixed-income investors, the core question is how to balance the supply shock from AI capital expenditure expansion against potential rate increases. The market currently prices about 15 basis points of a September rate hike and roughly 33 basis points of cumulative hikes by year-end. Alphabet's $4.35 trillion market cap makes it the largest AI hyperscaler, and its financing decisions ripple across the entire semiconductor supply chain — from Nvidia's GPUs to Broadcom's custom silicon and Micron's high-bandwidth memory.
