Social media keeps adding users, with over 5.4 billion people actively using social platforms worldwide in 2025. The industry has nearly doubled in less than a decade, rising from 2.73 billion users in 2017 to its current level, and social media ad spending is projected to reach $276.7 billion by 2025. That kind of growth is particularly important for smaller platforms that focus on local communities and local ads, rather than trying to compete directly with the largest social networks.
Nextdoor Holdings (NXDR) became one of the most talked-about stocks in December 2025 after Eric Jackson, the activist investor who helped drive a more than 15-fold rally in Opendoor (OPEN) shares during 2025, shifted his attention to the hyperlocal social network.
