    Ad Arbitrage Inventory Declines in Q2; Google AdExchange Leads Direct Sales

    Question

    Ad Arbitrage Inventory Declines in Q2; Google AdExchange Leads Direct Sales

    Direct answer

    The decline in arbitrage is a positive sign for the programmatic advertising ecosystem, indicating that more spend is reaching publishers directly rather than being siphoned by middlemen. This trend is driven by better enforcement of 'ads.txt' and 'app-ads.txt' standards. Google's continued dominance as a direct seller reinforces its moat in the ad-tech stack, even as it faces regulatory scrutiny. The low arbitrage in CTV highlights the premium nature of that inventory.
