Key relationships in depth

Scale AI & Meta

Meta acquired a 49% stake in Scale AI for $14.3B, with Scale AI co-founder Alexandr Wang joining Meta to lead its new superintelligence research lab. Scale AI is the largest provider of AI data labeling services, generating the high-quality training datasets that make large language models more accurate. The acquisition gives Meta in-house access to critical training infrastructure.

Why it matters: Meta is pivoting from open-source Llama models toward a proprietary superintelligence model requiring vastly more and higher-quality training data. Owning Scale AI eliminates training data supply chain risk and gives Meta a strategic advantage over competitors that must pay market rates for data annotation.
