LinkedIn, the go-to social platform for career-focused discussions, just hit a major milestone. Over the past year, its premium subscription services brought in a whopping $2 billion. This helped push the platform’s overall revenues up by 9%, even as it remains a quieter part of Microsoft’s massive earnings reports.

While LinkedIn isn’t sharing its total revenue for the year, the numbers are still impressive. Premium subscriptions alone now make up about 12.5% of its estimated $16.2 billion annual revenue. That’s a big jump from the $1.7 billion in premium revenue reported earlier this year.

Microsoft CEO Satya Nadella highlighted LinkedIn’s growth during the company’s Q2 earnings call. He also pointed out that while LinkedIn is thriving, Microsoft’s newer AI-driven businesses are growing even faster, with AI revenue hitting $13 billion this quarter—a 175% increase from last year.

Despite this, LinkedIn’s $2 billion premium revenue is a big deal. The platform has been adding new features, especially AI-powered tools like job-hunting assistance and professional development aids, to make premium subscriptions more appealing. These efforts seem to be working, with 40% of premium users already using these new tools.

LinkedIn CEO Ryan Roslansky shared that building a $2 billion subscription business is rare for any digital company. He emphasized LinkedIn’s focus on delivering value to users, helping them accelerate their careers or grow their businesses.

Although LinkedIn’s revenue growth is expected to slow slightly in the coming months, its ability to hit this milestone shows it’s still a key player in the professional networking space. With over 1 billion users, LinkedIn continues to prove its value—both to its users and to Microsoft.
