Concentration
Social, search and retail media make up 66.4% of 2026 spend and are forecast to reach 70.0% in 2028. Alphabet, Amazon and Meta take 59.7% of spend outside China ($659.6 billion), rising to 61.5% in 2028. WARC attributes growth to corporate AI investment and to the Olympics, the FIFA World Cup and US mid-term elections, and flags global tensions as a risk.
Our read
WARC’s release does not describe its method or how it allocated platform revenue, so treat the channel splits as estimates. The pattern matters more than the decimal: growth is concentrated, and channels outside those three need a specific case for budget.
