Waymo has added an additional $750 million to the $2.25 billion funding round that it first announced in March, bringing the total size of the financing (its first from investors outside of Alphabet) to $3 billion. The extension comes from new investors including those managed by T. Rowe Price, Perry Creek Capital, Fidelity Management and Research Company and others.

The extension, like the original round itself, will be used by Waymo to invest in its workforce, product development and operating its Waymo One ride-hailing service, as well as its Waymo Via cargo and goods transportation service.
