More than five percentage points over its benchmark rate is what Waymo will pay on the $5 billion it just borrowed, and the company that controls it is rated AA+. When Alphabet sold $25 billion of bonds in August, even its longest-dated tranche was marketed at about 1.55 points over Treasuries. Same family, and a premium more than three times as large.
The plumbing explains most of it. The loan is unrated, and the borrower is Waymo, not Alphabet. An unrated loan to a subsidiary gets priced on the subsidiary, and the premium Pimco, Blackstone and Sixth Street are charging looks like what lenders would ask of Waymo standing on its own — which suggests Alphabet's credit is not part of the package. Waymo is worth a lot on paper. It was valued at $126 billion in February, when it raised $16 billion of equity. But a valuation is not a cash flow, and lenders get paid out of cash flow.
What's interesting is that Waymo went to lenders at all. Until now it had funded itself with equity, from a family whose parent produced $73.3 billion of free cash flow in 2025. That has changed. Alphabet's free cash flow turned negative in the second quarter, minus $5.9 billion, after $44.9 billion of capital spending in three months. In June it announced $84.75 billion of new equity, $10 billion of it from Berkshire Hathaway, for AI infrastructure and compute. It has since lifted its 2026 spending forecast to as much as $205 billion. The cheapest money in the family is going into data centers.
None of that means Waymo is being starved. Alphabet still produced $53.3 billion of free cash flow over the trailing twelve months, and the loan grew because lenders wanted more of it: Waymo went looking for a little over $3 billion and left with $5 billion. That is demand, not rescue.
So inside one corporate family the same dollar now carries two prices — under two points when Alphabet borrows for data centers, more than five when Waymo borrows for cars. Waymo has spent its life funded by investors who wanted a piece of it. This week it learned what lenders charge to judge it on its own.
But a valuation is not a cash flow, and lenders get paid out of cash flow.
