Microsoft reports LinkedIn revenues as part of its Productivity and Business Processes segment, which also includes Office 365 and Dynamics 365. That segment contributed $14.7 billion total to Microsoft’s Q4 FY21 revenues of $46.2 billion. Some, but not all, LinkedIn revenues are counted by Microsoft as part of its Commercial Cloud category. Microsoft has a number of other businesses that make $10 billion annually, but gaming, security and now LinkedIn are the three newest members of this list.
