Waymo upsizes its first debt deal to $5 billion to fund global expansion

Waymo has borrowed its way into a new chapter. Alphabet’s autonomous vehicle unit announced on October 6, 2026, that it upsized its inaugural private debt financing to $5 billion, up from an initial estimate of more than $3 billion.

The money is earmarked for fleet expansion and rising AI and compute costs. That timing makes sense, because Waymo is trying to grow from a US robotaxi operator into a global one.

The details of the deal

Goldman Sachs arranged the financing. The lender list reads like a who’s who of private credit: Pacific Investment Management Co. (PIMCO), Blackstone Inc., and Sixth Street Partners all participated.

The loan is unrated. Put plainly, no credit rating agency has stamped a grade on it, so lenders are relying on their own homework about Waymo’s ability to pay them back.

Pricing is set at 5.25 percentage points above the benchmark rate.

The upsizing itself is the headline number. Going from a target above $3 billion to a final $5 billion suggests there was more lender appetite than Waymo initially planned to tap, and the company was happy to take it.

From equity darling to borrower

Waymo has historically funded itself with equity. In February 2026, it closed a $16 billion funding round that gave it a post-money valuation of $126 billion.

Raising debt is a different kind of move. Equity investors get a slice of ownership, while lenders get interest payments and their money back. Borrowing lets Waymo raise capital without handing out more of the company.

The operating numbers explain why the company needs so much cash. Waymo is currently running more than 500,000 paid rides per week across 14-15 US cities.

Its target is 1 million weekly rides across 20 cities worldwide by the end of 2026.

The international roadmap adds to the bill. Waymo is planning launches in London, Tokyo, and Munich, with testing or groundwork already underway, and launches aimed for 2026 and 2027.

Munich is targeted for late 2027 and would be Waymo’s first market in the European Union.

What this means

For Waymo, the shift to debt is a capital structure decision as much as a fundraising one. That approach protects existing equity holders, Alphabet included, from further dilution. The trade-off is a fixed obligation: interest at 5.25 percentage points over the benchmark has to be paid whether ridership targets land on schedule or not.

For the private credit industry, the deal is a notable win. PIMCO, Blackstone, and Sixth Street lending billions to an autonomous driving company shows that large non-bank lenders are willing to finance capital-heavy tech businesses, even without a credit rating attached.

Waymo also explicitly tied part of this raise to rising compute expenses, a reminder that the cost of running advanced AI systems is becoming a line item large enough to justify its own financing.

There are several things to watch from here. The first is whether Waymo hits its end-of-2026 target of 1 million weekly rides. The second is the international rollout in London, Tokyo, and Munich. The third is whether this becomes a habit, given the strong demand behind this $5 billion raise.
