📈 Advertising trends 2026: AI, programmatic and what advertisers should do

The advertising market is going through its fastest tectonic shift in the last twenty years. Artificial intelligence has stopped being an experimental add-on and has become the foundation for real-time bidding, dynamic creative optimization, and attribution. According to Market.us, the global AI advertising market grew from $8.6 billion in 2023 to roughly $12 billion in 2024 and is projected to reach $81.6 billion by 2033 at a 28.4% CAGR Market.us, 2025. The question for an advertiser is no longer "should we use AI" but "how do we get a measurably better result from it." In this piece, we break down the key numbers, technologies, and practical steps that define advertising trends for 2026.

💡 How to adapt your advertising strategy to 2026 trends

💡 Quick overview:

• Step 1: Assess your current share of programmatic buying and add Connected TV with retail media to your media mix
• Step 2: Implement dynamic creative optimization (DCO) to auto-optimize creatives for each audience segment
• Step 3: Set up first-party data collection and cookieless targeting before third-party cookies are fully phased out
• Step 4: Allocate budget to AI creative generation tools and redirect the time saved toward strategy
• Step 5: Add traffic verification (anti-fraud) and brand safety tools as a mandatory layer for every campaign

Artificial intelligence and automation: scale and numbers for 2026

AI is no longer a tool in a media buyer's hands but the environment in which decisions about bids, creatives, and targeting are made. The scale of AI penetration into the advertising ecosystem is illustrated by several figures. AI-driven programmatic buying grew 18% year over year in 2024 and reached $134.8 billion within a total digital advertising market of $258.6 billion IAB, 2025. According to eMarketer estimates, programmatic will account for 90% of the entire global digital display advertising market by 2026 data from Amra and Elma, 2025. Around 60% of all digital advertising spend is already influenced by AI technologies, from automated bidding to predictive segmentation Market.us (2025).

The dry return-on-investment numbers confirm the trend. AI-generated creatives deliver an average 47% higher CTR compared with manually produced creatives Mixflow.ai, November 2025. Campaigns with dynamic creative optimization achieve up to 58% higher ROAS and a 30% reduction in cost per acquisition Segwise.ai study, 2025. Google reports 17% higher ROAS for AI-managed video campaigns versus manually configured ones LoopexDigital, 2025. At the same time, companies that have fully integrated AI into their advertising processes record ROI 20-30% higher than competitors using traditional methods Mixflow.ai report, 2025.

The practical dividing line runs along "buys AI or uses AI." According to Basis Technologies (2025), 92% of advertising agencies use generative AI in some form, but only 44% of marketers report that their employer pays for such tools Basis Technologies survey, 2025. The gap between actual usage and formal budgeting creates a risk: specialists work in AI environments on personal accounts, without centralized quality control and brand safety. In 2026 it is critical to move AI out of shadow usage and into a managed stack.

Programmatic, Connected TV and retail media: the triple growth engine

The programmatic ecosystem is no longer limited to display inventory. Three segments growing at an accelerated pace deserve separate attention from advertisers in 2026.

Connected TV. CTV advertising in the US will reach $32.6 billion in 2025 with 13% annual growth, and 75% of inventory is sold programmatically IAB, 2025. Global programmatic video spend exceeded $110 billion in 2024, and video accounts for nearly 75% of new programmatic dollars in the 2024-2026 period Basis Technologies, 2025. Video completion rates on CTV exceed 95% (versus 72% for digital overall), which makes the format attractive for brandformance campaigns.

Retail media. Retail media remains the fastest-growing digital advertising channel. Amazon Ads generated $55 billion in 2025, Walmart Connect reached $4.5 billion Marketing LTB data, 2025. The global retail media market is projected to approach $140 billion by 2026 Marketing LTB summary, 2025. Advertisers report that retail media ROI is twice as high as social advertising, and 78% of brands plan to increase budgets in this channel in 2025.

Mobile programmatic. Smartphones generate 71% of all programmatic spend Marketing LTB review, 2025, and in-app advertising shows three times higher engagement compared to mobile web. For advertisers this means mobile video and native in-app advertising are not optional, they are a required component of the 2026 media plan.

Summary of key segments:

Dynamic creative optimization: creative on an assembly line

If programmatic answers the question of "where and to whom," DCO answers the question of "what exactly to show." Dynamic creative optimization assembles an ad message from modular components (headline, image, CTA button, color scheme) in real time for a specific user, context, and funnel stage.

The numbers are impressive. Brands using DCO report CTR increases of 20-60% compared to static creatives Marketing LTB analytics, 2025. AI-enhanced DCO campaigns deliver up to 58% ROAS growth and a 30% CPA reduction Segwise.ai, 2025. The L'Oreal case is particularly telling: the company used generative AI and cut its product content development cycle by 60% L'Oreal case, Mixflow.ai, 2025. On average, companies save around $4,000 for every 10 ad sets when using AI generators instead of traditional methods.

An important nuance: 99% of agencies consider DCO a significant element of strategy, with 45% rating it as "very significant" Digiday/Clinch, 2024. However, creative rotation must be regular. Refreshing every 10-14 days significantly reduces "audience fatigue," but the top 2% of creatives still absorb 53% of ad budgets in gaming and 43% outside gaming Segwise.ai report, 2025. In other words, betting on DCO does not cancel the Pareto principle: a small share of creatives drives the lion's share of results.

Anti-fraud, brand safety and cookieless targeting: the new reality

The flip side of automation is vulnerability. Global ad fraud losses will reach $41.4 billion in 2025 (up from $37.7 billion in 2024), according to Spider Labs based on analysis of 4.15 billion ad clicks across seven countries SpiderAF, 2025. Brand safety remains the top programmatic market concern for 58% of advertisers.

At the same time, the cookieless transition is unfolding. Early Chrome tests without third-party cookies showed a 30% drop in effectiveness Shno.co, 2025. In response, 90% of marketers call first-party data the key driver for improving ad performance Marketing LTB study, 2025. Personalized ads deliver 80% higher engagement, and 60% of users prefer ads relevant to their interests Marketing LTB estimate, 2025.

The practical takeaway for 2026: the end of third-party cookies is not an apocalypse, it is a push to build your own data infrastructure. Companies that invested in collecting and activating first-party data in 2024-2025 enter 2026 with a competitive advantage.

Case study: how a mid-size advertiser rebuilds the media mix in 2026

Let's look at a typical scenario. A mid-size advertiser (e-commerce, roughly $5 million in annual revenue) works with a media budget of about $240 thousand per year. Before 2024, the structure was classic: 55% of the budget went to search (Google Ads), 25% to targeted social media advertising, 15% to the display network, and 5% to experiments.

After an audit and media mix rebuild in early 2025, the structure changed:

Six months after the rebuild, cost per conversion dropped by more than a fifth, and revenue per ad dollar grew by roughly a third. The key factor was reallocating budget away from saturated search auctions toward Connected TV and retail media, where competition is still lower and relevance of the touchpoint is higher.

⁉️🤔 Frequently asked questions

How essential is it to use AI in advertising in 2026?

AI in advertising in 2026 is not an option, it is the hygiene baseline. Automated bidding systems, predictive targeting and creative generation are already built into the major platforms (Google Ads, Meta Advantage+, Amazon Ads). An advertiser not using AI loses auctions to one who does, because bids are calculated algorithmically based on hundreds of signals. According to Mixflow.ai, companies with full AI integration report ROI 20-30% higher.

What is DCO and why do I need it if my volumes are small?

Dynamic Creative Optimization automatically assembles and tests combinations of headlines, images and calls to action for each audience segment. For small advertisers, DCO is fundamentally more cost-effective: instead of hiring a designer for every banner variation, the platform generates dozens of combinations and keeps the most effective ones. Savings amount to about $4,000 per 10 creative sets, and CTR growth reaches 47% Mixflow.ai, 2025.

How do I protect against ad fraud in programmatic buying?

Protection works on three levels: enabling verification on the DSP side (double domain checks, exclusion lists), connecting an independent anti-fraud vendor (DoubleVerify, IAS, SpiderAF), and regular audits of post-click metrics (time on site, scroll depth). According to SpiderAF, fraud losses reached $41.4 billion in 2025, with the RTB segment being the most vulnerable. Private marketplaces (PMPs) with verified inventory are growing 26% per year precisely as a response to the brand safety demand PMP estimate, Marketing LTB, 2025.

Are CTV and retail media for large brands or for mid-size businesses?

Both channels are becoming democratized. CTV inventory is available through self-serve DSPs (The Trade Desk, DV360) with a minimum threshold starting at a few thousand dollars for a test campaign. Retail media through Amazon Ads lets you start with a budget of $100 per day. For mid-size e-commerce, retail media delivers ROI twice as high as social advertising, and CTV delivers a completion rate above 95% CTV data, Marketing LTB, 2025, meaning the message is seen in full.

How do I prepare for the full phase-out of third-party cookies?

Focus on three areas. First: collecting first-party data through registrations, subscriptions, and loyalty programs. Second: adopting contextual and semantic targeting (ads based on page content rather than user profiles). Third: testing alternative identifiers (Unified ID 2.0, RampID, ID5). Personalized advertising based on your own data delivers 80% higher engagement Marketing LTB, 2025.

Bottom line: what advertisers should do right now

The 2026 advertising market is defined by four key traits: AI is becoming infrastructure rather than a tool; Connected TV and retail media are growing ahead of the curve and offer a window of opportunity before auctions become saturated; creative production is moving to a DCO assembly line with measurable ROI; data protection and anti-fraud verification are no longer optional.

The practical roadmap comes down to five steps: move AI tools out of shadow use into a managed stack, reallocate at least 15% of budget toward CTV and retail media, launch DCO campaigns on at least one anchor (Meta Advantage+ or Google Performance Max), build first-party data collection, and enable anti-fraud verification across all programmatic buys.
