The week in one paragraph

This was the week the market priced what publishers already knew. Q2 earnings did the talking: Amazon cleared $19.8B in quarterly ad revenue, up 26%, and barely mentioned it; Meta grew ads 27% while its expenses grew 55%; and Reddit posted a 64% ad quarter and still fell nearly 13%, marked down for the one exposure most publishers carry — an audience that arrives via Google. Publishers spent the same week converting exposure into terms. Time became the first major publisher to sell ads to AI bots, on a site that sees more bot traffic than human traffic most days; the newsrooms that were threatening to block Googlebot are now seriously modelling what it would cost, against publisher ad supply down as much as 40% year over year; and PubMatic shut down its open-web wrapper, handing ~250 publishers to Playwire and conceding the wrapper is no longer a business worth owning. The buy side moved its margin around — holdcos are burying AI costs inside principal media commitments, and Omnicom’s third-party service costs, where principal earnings sit, jumped from $918M to $1.5B — while Google piloted the first real PMax opt-outs since 2021, FreeWheel switched on show-level reporting for seven streamers, Xbox began testing ad-supported game streaming, the IAB Tech Lab shipped AAMP 2.3 with Agentic Audiences finalised, and the FTC sued Hims & Hers over health data shared with Meta and Snap. The through-line is leverage: this week the parties who hold it started writing rate cards, and the parties who lost it started paying in margin.
