How many messages are sent on WhatsApp each day?

How to get close to this number

Multiply users by messages. The service has around two billion users, and an active messaging user sends and receives dozens of messages a day across personal and group chats. Two billion times a few dozen gives a figure in the tens of billions, and group chats push it toward a hundred.

Group messaging is what inflates the count beyond one-to-one intuition. A single message sent to a group of twenty counts once as sent but produces twenty deliveries, and in many countries group chats are the primary use. Message counts in a group-heavy platform behave very differently from those in a purely bilateral one.

The encryption detail in the explanation is the structurally significant one: all of these messages are end-to-end encrypted, so the company operating the largest messaging system on Earth cannot read any of it. That is an unusual position for a platform business, and it is why the company's disclosures are about volume rather than about content.
