Jamie MacEwan was quoted in Campaign on "Omnicom, WPP, Publicis and Havas share prices plummet amid AI sell-off"
4 February 2026Jamie MacEwan, senior media analyst at Enders Analysis, said that agencies were facing “sentiment volatility that will be tough for ad agencies to shake”.
He added: “Like it or not, their customers continue to spend big on Google and Meta. This leaves agencies increasingly dependent on a handful of platforms where they are outspent by SMEs and exposed to AI tools. That doesn't mean there isn't a lot for agencies to offer their clients in a complex media world, but clearly real-terms growth on a sector level will continue to be a struggle. That is why even Publicis' years of outperformance have not been significantly rewarded.”
