Meta's proprietary AI creative drives ad revenue.
Meta's AI investments are already bearing fruit, with advertising revenue growing 33% on a $55 billion base. Its new image model is trained on proprietary Meta data, including ROAS and pixel signals, so Meta can create ads no other lab can fine-tune for the same use case. This AI-generated creative attacks the core advertiser bottleneck of producing great creative, removes the spending constraint, and gives Meta a tangible output to prove AI ROI to skeptical investors.
