YouTube now outpaces Reddit in AI citations as models prioritize transcripts, metadata, and explanatory formats over engagement signals.

AI platforms’ long-held anti-advertising stance changed in January 2026. The rising cost of competing in AI has forced OpenAI and Google to launch AI ad pilots, and other platforms will likely follow suit. But advertisers may not be the winners in this gold rush.

A new policy bans buy-for-me bots without permission, as the retailer looks to control the agentic shopping experience.

Heavy consumer AI health use raises pressure on OpenAI and peers to tighten safeguards fast.

Google’s Universal Commerce Protocol promises a common standard for agentic commerce. But AI-driven checkout will remain small for the foreseeable future, keeping the focus on how AI influences discovery rather than where transactions are completed.

ChatGPT will begin testing ads, but while its massive userbase positions the platform to deliver ads to engaged audiences, brands must weigh the risks.

Nearly 6 in 10 US teens (59%) say they've used ChatGPT, more than double Gemini's 23%, according to an October survey from Pew Research Center.

Google’s latest AI tools let users buy via chat as the company tries to turn its search dominance into agentic commerce gains.

Our analysts (or “bakers”) compete in a Great British Bake Off–style episode, discussing why Google may overtake OpenAI in 2026 and how the AI boom could get a reality check this year.

ChatGPT Health lets users upload medical data for personalized wellness advice—a feature likely to gain traction as folks trade in data privacy for AI-powered health insights.

Despite added personalization, Pfizer, Verily, and others will struggle to draw health-information seekers away from ChatGPT and Gemini.

In a year marked by platform volatility, AI acceleration, tariff shocks, and shifting consumer behavior, marketers searched for clarity across EMARKETER’s most-read topics. The top 10 themes reflect where advertiser attention truly moved in 2025. These trends captured the forces reshaping performance, discovery, and measurement: AI-driven optimization, creator-centric social ecosystems, commerce-led advertising, and CTV’s rise as the new premium video default. Together, they tell the story of a market recalibrating around efficiency, accountability, and cultural relevance as marketers prepared their 2026 strategies.

Walmart’s OnePay adopted Google’s Agent Payments Protocol (AP2) to drive agentic commerce as a credentialled provider, per a press release. With Chrome remaining consumer’s most popular browser, Gemini is narrowing the gap with ChatGPT as the most used chatbot: We forecast that by 2029, Gemini will hold 53% of genAI market share. That in turn could give Google’s AP2 a large share of agent-driven consumer spend in the long term, as consumers develop loyalty and use patterns around AI platforms.

Over one-third of Gen Z (39%) and millennials (34%) who have used genAI tools to check symptoms report that they would put off seeing a doctor if the AI told them their issue was low-risk, according to an October 2025 poll from The Mesothelioma Center at Asbestos.com conducted by SurveyMonkey. Overrelying on AI for medical guidance carries real risk, especially as models are still maturing and sometimes produce faulty information. AI companies should add explicit in-chat disclaimers against being used as a replacement for medical care and strengthen guardrails to block unvetted or potentially harmful health advice.

As consumers grow more comfortable with using AI, retail industry leaders see 2026 as a pivotal year in shaping how the emerging technology disrupts the way people shop.

Consumers are integrating AI into everyday health searches as tools grow more conversational, even though output reliability remains uneven. The balance of speed, accuracy, and trust will shape how people use AI for information and care.

BNY will integrate Google Gemini Enterprise into Eliza, its in-house AI platform. Gemini will give Eliza deep research tools and let BNY’s employees build AI agents that draw from and act on the bank’s vast libraries of financial data. The haves and have nots of banking’s AI era are coming into relief. The top strata are institutions that have invested heavily in data infrastructure that supports AI’s needs. The next strata are developing dedicated AI strategy but aren’t building as much in-house. Banks in the final strata haven’t found ways to use AI at scale but need to now.

Google is quietly exploring how Gemini could support advertising in 2026, per Adweek, even as the company publicly denies any such plans. Agencies say Google has framed potential Gemini ads as high-intent, conversational opportunities for ecommerce brands—signals emerging alongside rapid user growth. Gemini’s global MAUs have climbed roughly 30% since August, and its US footprint is projected to reach 85.7 million users by 2029. If prompt-level signals become targetable, conversational AI could function as a new, more precise form of intent advertising.

In 2026, dominant platforms like Google and Amazon will flex their muscle against ChatGPT; smaller players like Perplexity and Claude will need to make either product moves or M&A moves; and AI-focused marketers will spend more on YouTube than ads on AI platforms.
