Industry
The Competition Appeal Tribunal certified a collective claim worth up to £5bn against Google, covering advertisers who bought UK search ads between 2011 and 2025. The case is opt-out: every qualifying UK advertiser is in the class by default.
Anthropic
Self-hosted environments let Claude Code sessions run on your own infrastructure, started from web, mobile, desktop, or a routine, next to internal services and security controls.

"The Beginning of ChatGPT Ads", to be published at AAAI/ACM AIES 2026, examines OpenAI's early advertising rollout from a computers-and-society perspective.
Gemini

Industry
Teads filed an 85-page antitrust complaint against Google in the Southern District of New York on 3 August, seeking treble damages over 6.88 trillion impressions it says were diverted from rival exchanges via Dynamic Allocation, Last Look, and Project Bernanke. In the same SEC filing, Teads warned Google could retaliate by cutting its revenue: an unusually candid dependency disclosure.
ChatGPT Ads
OpenAI’s August update confirms that ChatGPT Ads has launched in Brazil and Mexico. Carlos Romero’s accompanying account of early testing offers practical observations on budget control and campaign focus.
Anthropic
Thousands of shared Claude conversations were found indexed and publicly searchable on Google, exposing chats users believed private.
Industry
Four days after the US President called the DMA fines illegal and discriminatory, the Department of Justice and state co-plaintiffs formally supported Google's appeal. This continues the €890m penalty story from Week 30.
Industry
OpenAI cut GPT-5.6 Luna token prices by 80% and Terra's by 20% in the API. Intelligence that was frontier-class a year ago now costs about six cents on the dollar per task at nearly nine times the speed, with gains spanning the model, inference stack, and agentic harness.
Industry
The European Commission President announced up to €10bn of investment in European AI Gigafactories, positioning Europe as an AI power in its own right.
Google Search Console
Platform properties are now live for all Search Console users, tracking how Instagram, TikTok, X, and YouTube posts perform on Google Search, Discover, and News. Connecting an account creates a new property per platform.
Industry
Apple became the second company to surpass $5tn in market value, having avoided the $700bn-plus AI compute arms race. Days later, it reported Q3 revenue up 16% to $109.4bn: iPhone up 22%, Mac up 29%, China up 22%: though shares fell about 7% on the outlook.
YouTube
Google published a help page for YouTube audio ads. The format is not new, but the documentation formalises specs and availability.
Industry
From 2 August, the European Commission's AI Office and national authorities enforce the AI Act, with fines reaching €35m or 3% of global revenue and a 38-person enforcement team stood up in Brussels. The rules reach well beyond model makers to companies deploying AI, and the Act also bans tools built to mass-produce non-consensual sexual imagery, including nudify apps and deepfake generators.
OpenAI
OpenAI's advertiser email confirms daily budgets now work on a seven-day average: spend can reach twice the daily budget on any day but must not exceed the weekly average. This formalises the change covered in Week 27, matching Google's pacing model.
Google Tag
The latest Data Manager API release adds a RemoveAllAudienceMembers method, simplifying audience list clearing.
Reddit Ads
Reddit's new generator builds free-form ads from real community conversations: you provide your website, media, and context, and its Community Intelligence produces a brand summary, audience insights, and ad concepts, with drafts informed by KarmaLab best practices. Free-form ads have delivered twice the CTR of standard formats since 2024, with Canada Goose seeing a 10.5-point ad awareness lift and the UK Department for Transport a 14-point action intent lift.
Google Search Console
The Generative AI performance report is rolling out to more users, with Google promoting it in-console. It shows site performance in generative AI features on Google Search.
ChatGPT Ads
Juozas Kaziukėnas found an Ads Manager setup that directs an ad click into a business-agent conversation. He had not seen the resulting consumer ad live, so the evidence establishes a setup test rather than a completed public rollout.
Industry
Google rewrote its Crawl Budget documentation. Every site starts with a conservative crawl budget that adjusts based on demand and server capacity.
Google Merchant Center
The Ask Advisor chat, announced for Google Ads in May, is now appearing in Merchant Centre. Some accounts show an AI insights summary, a search box with suggested queries, and previous chats.
Industry
A federal court threw out Google's case against SerpApi, a company scraping Google Search results. Google argued bypassing its anti-bot systems was unlawful; the court disagreed.
Google Merchant Center
Google has confirmed a fix for the Shopify product ID issue that threatened merchants with lost product history. This closes the caveat first raised in Week 25 alongside the server-to-server integration.
Anthropic
The Claude Security plugin scans code for vulnerabilities before commits or across a codebase, from the terminal. It runs on the Claude inference you already pay for.
Industry
Google launched both AI Overviews and AI Mode in France, announced by Search lead Elizabeth Reid. France had been a notable holdout market.
ChatGPT Ads
Three ChatGPT Ads changes landed together. For you, this means the platform is maturing fast while shifting spend control, so recheck budget pacing under the weekly model.
Microsoft Advertising
Bing is showing ads that visually pop out during scrolling. The animated treatment appeared for multiple observers this week.
BigQuery
Scheduled BigQuery queries set exactly on the hour can execute twice. Scheduling a few minutes before or after the hour avoids the double run.
