Meta's European ad revenue growth slows to 18% year over year in Q3

WIRED reports Meta's European ad revenue grew 18% year over year in Q3, down from about 40% in Q1 and 24% in Q2; US and Canada saw 33% growth in Q3. Meta began offering less-personalized ads to EU Facebook and Instagram users in early 2026. Meta did not explicitly blame the option for slower growth, though its finance chief previously called it a possible headwind and an analyst told WIRED it was contributing.
