Global advertising revenue is expected to increase by 6.8% next year, meaning it is on track to hit $1.1trn (£864.4bn) in 2025, a year ahead of earlier forecasts, according to GroupM’s latest This Year Next Year report. The business predicts global ad revenue will grow 7.8% to $989.8bn (£778.7bn) this year, an uptick from the 5.3% growth predicted in December. Despite ongoing inflation in many markets, consumer spending has remained resilient, while AI has driven business investment throughout the first half of the year.
