UK Marketers Cautiously Boost Budgets Amid Economic Uncertainty
UK marketing budgets rose for the second straight quarter in Q3 2025 according to the IPA Bellwether Report, though growth slowed amid economic and political uncertainty ahead of the Autumn Budget. The net balance was +3.6%, down from +5.5% in Q2, with 22% of panellists reporting increases and 18.7% reporting reductions. Growth was driven by events and direct marketing, while main media budgets remained flat; video and online categories grew, but budgets for published brands, audio, and OOH declined, and sales promotions fell to -0.9% from +9.4%. The IPA kept its 2025 ad spend forecast at 0.6%, while 2026 forecasts were trimmed from 1.6% to 1.2%. The report emphasizes balancing immediate ROI with long-term brand building, as AI tools reshape research and targeting and push spend toward ABM, LinkedIn, Meta, earned media, and programmatic channels. Industry voices stress accountable measurement, stronger brand storytelling, and a continued shift toward omnichannel strategies into early 2026.
Quarterly industry budget trends and AI-driven shifts provide meaningful insight into the advertising landscape; not a platform policy or earnings event.

OpenAI's Measurement Gaps Keep ChatGPT Ads Budgets at Test Level
Seven months after OpenAI introduced ads in ChatGPT, marketers still face measurement hurdles, as agencies like Accuracast report discrepancies—zero conversions despite form fills and 100 clicks vs. 20 tracked internally—along with 24-36 hour delays and a lack of demographic or prompt data. Legal concerns about OpenAI's terms and data use deter many from enabling conversion tracking, slowing custom audience adoption. Test budgets range from £10,000 to £30,000, with clients spending under $100,000 monthly on ChatGPT versus $10 million on Google. Third-party measurement through partners like AppsFlyer and Adjust is deemed essential, though limited. Meanwhile, DoorDash expands retail media by partnering with Macy's, Timberland, and others, the Trump administration spends millions on pro-Trump ads, Swap Commerce acquires Vizby, and OpenX hires John Rogers as SVP of Global Publisher Development. OpenAI declined to comment.
AI agents threaten advertising as we know it
AI agents like Meta's Muse, OpenAI's ChatGPT, and Google's Gemini are disrupting traditional advertising by not clicking banners or sponsored results, threatening the core revenue of platforms like Meta and Amazon. New monetization models include subscriptions, transaction fees, and pay-for-results. Protocols such as Google's Universal Commerce Protocol, OpenAI/Stripe's Agentic Commerce Protocol, Visa's Trusted Agent Protocol, and Ad Context Protocol standardize agent-commerce interactions, creating new ad slots within agent workflows. Early signals include Amazon blocking Muse and declining Google traffic to news sites. Despite the threat, ad giants report growth, including ChatGPT ads reaching $1 billion annualized revenue, proving ads work in AI assistants, especially at the top of the funnel. Adoption remains early, with only 5% of US consumers using agents for fully autonomous purchases.
