This week’s edition is about the platforms themselves, and what happens when they all move at once. Netflix has pushed UK prices again to accelerate the migration into its ad tier. Magnite and ITN have launched agentic buying for local TV. Teads has opened up half a billion connected TV home screens as an ad surface. Amazon and OpenAI have struck a deal that puts Amazon DSP advertisers directly inside ChatGPT. Australia is set to let users switch off social media algorithms altogether. And the IAB has lifted its 2026 US ad forecast on the back of AI-directed spend. Every one of these lands on a plan somewhere this quarter, and the operational implications are already stacking up.
Netflix has hiked UK prices again with the cheapest plan up by a third, widening the ad-tier gap
Netflix has raised UK subscription prices this week, with the cheapest ad-supported plan up by roughly a third and the standard and premium ad-free tiers also rising. The move follows recent Ampere Analysis and Performance Marketing World data showing UK ad-supported subscribers overtaking ad-free, and both Netflix and Amazon Prime Video seeing UK audience declines even as the overall ad tier grows. The price rise widens the gap between what users pay for an ad-free experience and what they pay for the ad-supported tier, and history from the US suggests price gaps at this level accelerate migration into the ad plan meaningfully. Netflix has been increasingly transparent that ad-supported subscribers are the priority for growth in 2026 and 2027.
What this means: Netflix is deliberately widening the price gap between ad and ad-free plans to accelerate subscriber migration into the ad tier, and it is working. For CTV plans, this means the addressable UK Netflix ad audience is growing faster than most 2026 budgets have modelled. The rate card conversation is now urgent. Media teams should be negotiating hard on premium placement commitments and minimum spend terms before the ad-tier subscriber base grows and Netflix’s negotiating position hardens. This is the moment to lock in favourable terms, not next quarter.
Magnite and ITN have launched agentic local TV buying, collapsing weeks of RFPs into hours
Magnite and ITN have announced an integration that lets media buyers submit a single RFP across local linear and CTV inventory using AI agents, with full rollout landing in Q4 2026. The ITN agent enters Magnite Orchestration, Magnite’s programmatic buying environment, and negotiates on behalf of the buyer across local station groups and connected TV publishers in the same request. Historically local TV buying has been one of the slowest and most manual parts of a media plan, with weeks of RFPs, negotiation rounds and manual reconciliation. The Magnite and ITN integration compresses that process into hours and gives buyers unified reporting across linear and CTV for the first time.
What this means: This is the first live example of agentic buying working across the traditionally slowest part of a media plan. If the Q4 rollout lands as described, the case for keeping local TV out of a converged media plan collapses. Agencies that have avoided local linear because of the operational cost will suddenly have a reason to include it, and the audience reach numbers will start to look meaningfully different. The broader signal is more important. Every major SSP and DSP is building agentic buying layers this quarter. The teams that get hands-on with them first, and build their planning workflows around agent-mediated buying, will be operating on a different cost base to teams that treat it as a future consideration.
Teads has opened up connected TV home screens as an ad surface across 500 million devices
Teads has brought Whale TV home screen inventory into its ad manager, giving buyers access to home screen placements across roughly 500 million TV devices worldwide in more than 100 countries. Whale TV powers 47.5 million active TVs directly and works with more than 400 device brands, and the deal deepens a partnership first struck in 2024. The inventory sits on the TV home screen itself, the first surface a viewer sees before choosing an app, which is one of the highest-attention ad placements available on any connected device. Teads is positioning the new inventory as a premium, brand-safe alternative to the in-app CTV placements that dominate current CTV buys.
What this means: TV home screen inventory has been one of the most valuable placements in CTV, but until now it has been sold in patchy, direct-only deals through individual OEMs. Bringing it into a single ad manager at 500 million device scale changes the buying dynamic materially. For UK brands running CTV, this is a new premium placement worth pressure-testing against existing in-stream CTV buys, particularly for upper-funnel awareness campaigns where the home screen environment carries more brand equity than a pre-roll. The direction of travel across CTV is consistent: the surfaces around content, not just the ads inside content, are becoming a bigger share of the buy.
Amazon and OpenAI have struck a deal to put Amazon DSP advertisers directly inside ChatGPT
Amazon confirmed on Wednesday that select US advertisers can now buy into ChatGPT through Amazon’s demand-side platform. Campaigns are set up and managed inside Amazon DSP, while OpenAI’s own ads system controls all delivery decisions. Ad units appear as text or images beneath ChatGPT responses. Amazon described conversational ad formats as the “fastest growing engagement opportunity” for brands, with Chris Conetta, director of omnichannel supply at Amazon’s DSP, framing the deal as letting advertisers “extend their campaigns further into where their customers are actively spending time”. Delta Vacations is among the launch trial participants. The move gives Amazon a direct route into the fastest-growing paid inventory outside of Meta and Google, and gives OpenAI immediate access to the deepest pool of commerce-intent advertisers in the market. Adform announced this week that it has also gained a managed route into ChatGPT for European buyers, mirroring the Amazon deal from a European DSP position.
What this means: This is the moment ChatGPT Ads becomes a serious buying environment. Until now, running on ChatGPT meant a direct OpenAI relationship and a bespoke measurement stack. From this week, any brand already spending through Amazon DSP can add ChatGPT inventory to an existing campaign, using the same audience data and reporting frameworks, and European buyers can do the equivalent through Adform. For UK teams, expect a formal UK inventory rollout within six to twelve months and expect other DSPs to follow with their own OpenAI integrations. The practical action for the next quarter is to audit which brands in your portfolio are Amazon DSP or Adform customers and to pressure-test whether the existing measurement and creative infrastructure would translate cleanly to conversational placements. The teams that treat this as a live channel option, not a future consideration, will be first through the door when the UK inventory opens.
Australia is passing a world-first law letting users opt out of social media algorithms
Australia has proposed legislation, now expected to pass this autumn, requiring platforms including Meta, TikTok, YouTube and X to let users opt out of algorithmic content ranking entirely. Users will be able to switch to a chronological feed or a topic-based feed with no personalisation, and platforms will have to make the option obvious rather than buried in settings. The UK, EU and Canada are all watching the Australian model, and the direction of travel across Western markets is clearly toward more user control over what platforms show them.
What this means: Algorithmic feeds are the mechanism paid social relies on to reach the right audience at the right moment. If a meaningful share of users opts out, particularly in one of the platforms’ most valuable Western markets, the addressable audience for personalised paid social shrinks. This is not just an Australian story. Brands running paid social should be modelling a scenario where 15 to 25% of engaged users in Western markets opt out of algorithmic ranking within 18 months. Contextual targeting, community-led creator content, retail media and owned channels become materially more important in that world. Plans built entirely on lookalike targeting need a credible backup route to reach the same audience.
The IAB has lifted its 2026 US ad forecast to 12.3% growth as AI tools now direct 12% of spend
The IAB has upgraded its 2026 US advertising growth forecast by 2.8 percentage points to 12.3%, on the back of a stronger than expected first half. The revised outlook surveyed more than 200 buyers, with 63% saying customer acquisition is climbing and 86% expecting AI to change how they measure media within the next twelve months. Alongside the forecast, the IAB reported that AI-driven tools now direct roughly 12% of ad spend, a share that has doubled inside a year. The combination points to an ad market that is not just growing faster than expected, but reshaping its buying decisions around AI-mediated placement and measurement at pace.
What this means: A 2.8 point forecast upgrade mid-year is a genuinely bullish signal. The interesting bit is not the top-line growth number, though. It is that AI-driven tools are now allocating 12% of ad spend, and that 86% of buyers expect AI to change how they measure media within twelve months. Measurement change is the leading indicator here. Teams that have not started rewriting their measurement frameworks to account for AI-mediated placement, incrementality across agentic buying layers, and share-of-AI-answer as a KPI will find themselves reporting against a benchmark that no longer describes the market. This is the practical output of every story above this one in this week’s edition, all landing at once.
