Alphabet returns to bond market as AI spending accelerates

Alphabet has a problem that most companies would love to have: its AI ambitions are growing faster than even its considerable cash flows can comfortably support. So the Google parent is going to the bond market.

The company is planning a bond offering of up to $25 billion, its third major debt raise of 2026. The proceeds are earmarked for AI infrastructure and repaying existing debt.

The bond parade of 2026

Back in February 2026, Alphabet completed a roughly $32 billion bond sale spanning multiple currencies. That deal included a 100-year sterling bond, the first of its kind from a tech company since 1997.

In May, Alphabet followed up with a six-tranche euro bond deal worth at least €9 billion, or about $10.5 billion. That was the largest euro-denominated bond the company had ever issued.

Now comes the August $25 billion offering. Add it up and Alphabet has raised, or is in the process of raising, the better part of $70 billion in debt in under a year.

What $185 billion buys you

Alphabet’s capital expenditure guidance for 2026 sits between $185 billion and $190 billion. That figure is nearly double what the company spent in 2025.

Industry-wide AI infrastructure spending is projected to surpass $700 billion in 2026. Microsoft, Amazon, and Meta are all running similar playbooks, pouring capital into data centers, custom chips, and the physical real estate required to house the servers that power large language models.

What this means for bond and equity investors

The bond market has noticed. Credit spreads for major AI investors, including Alphabet, Amazon, and Meta, have widened as investors demand higher yields to compensate for the perceived risk of runaway capital expenditure.

For equity investors, heavy capex spending can compress near-term free cash flow and weigh on margins. The counter-argument is that the companies winning the AI infrastructure race today are building the revenue-generating moats of the next decade.

The 100-year sterling bond Alphabet issued in February captures the scale of this commitment. Whoever holds that bond to maturity will be collecting interest payments well into the 22nd century. What’s not in question is that Alphabet is now structurally committed to a level of external financing that marks a genuine departure from how it has historically operated.
