The $2.59 Billion Content Moderation Challenge
The AI content moderation market is projected to expand from $1.03 billion in 2024 to $1.24 billion in 2025, potentially reaching $2.59 billion by 2029. This growth reflects a critical reality: platforms cannot manually review the massive volume of daily user-generated content.
