Walmart is taking a stake in General Motors' Cruise autonomous car division, the companies announced Thursday.
The retail giant has joined a funding round originally announced in January at $2 billion which has now been updated to $2.75 billion, Cruise said.
Microsoft, a Cruise technology partner, also participated in the round, which valued the San Francisco-based LLC at over $30 billion.
Cruise is developing self-driving technology aimed at commercial uses including ride-hailing and delivery and partnered with Walmart for a test in Phoenix, Ariz., using electric vehicles last fall.
"The investment will aid our work towards developing a last mile delivery ecosystem that’s fast, low-cost and scalable," Walmart CEO John Furner said in a statement.
Cruise is currently testing modified Chevrolet Bolts on public roads in San Francisco without backup drivers and plans to introduce the electric Origin shuttle with no provisions for a driver in the coming years.
Along with its Cruise partnership, Walmart has tested self-driving delivery methods with several companies, including Nuro and Gatik, and is aiming to be zero emissions by 2040.
