Uber Technologies Inc., fresh off losing out on a deal to buy meal delivery platform Grubhub, is now in talks to buy rival delivery service Postmates Inc. for $2.6 billion, according to the Wall Street Journal.

Postmates is widely considered the fourth largest meal delivery platform in the U.S., trailing Grubhub, Uber Eats and DoorDash.

The report said such an agreement, if completed, could be announced as early as next week.
