Alphabet targets up to $25 billion bond sale specifically earmarked for AI infrastructure spending, the largest single financing commitment for data center capex.

Alphabet is seeking to raise as much as $25 billion through a multi-tranche U.S. investment-grade bond offering as the company continues to fund its expanding AI infrastructure investments. The offering could include maturities ranging from two to 40 years and is expected to comprise up to 10 separate tranches, with initial price talk for the 40-year notes set at approximately 155 basis points above U.S. Treasuries.

This bond sale follows Alphabet's upward revision of its 2026 capital spending outlook to as much as $205 billion, reflecting the company's substantial commitment to AI infrastructure development. The offering comes amid broader signs of softer investor demand for AI-related debt, as evidenced by recent bond issuances from Meta-backed and Amazon-linked issuers that have faced weaker investor reception.

The timing highlights the scale of Alphabet's financing needs. The company has already raised more than $50 billion in debt during the first half of 2026 and issued nearly $85 billion of equity earlier this year. The increased spending has had tangible consequences for the company's financial metrics—Alphabet reported its first quarter of negative free cash flow since its 2004 IPO, a significant milestone reflecting the capital-intensive nature of current AI infrastructure buildout.
