Goldman Sachs Deep Dive: AI Is Rewriting the Logic of the Advertising Industry

Today, we’re sharing Goldman Sachs’ latest industry report, released on October 14.

 

 

This report covers the entire U.S. digital advertising industry, including platforms like Alphabet, Meta, Pinterest, and AppLovin, and serves as the market’s most closely watched quarterly outlook for the “AI-driven ad cycle.”

1. Core Takeaway: Q3 Ad Industry Performance “Better Than Expected”

Goldman Sachs believes the U.S. digital ad industry outperformed market expectations in Q3, though companies still lack clear direction for 2026 ad budgets. Three key trends stand out:  

1️⃣ Direct Response Ads remained strong, particularly in July and August, with sustained recovery in e-commerce and SME spending.  

2️⃣ Brand Ads were weaker but showed slight improvement starting in September, providing tailwinds for Q4.  

3️⃣ Experimental Budgets remained volatile, with smaller platforms facing significant pressure in September.  

 

 

In other words, advertisers are still assessing the conversion efficiency of AI tools, but major platforms have already gained an edge in “quantitative advertising” and “automated budget allocation.”

2. Industry Theme: AI-Driven Ad Transformation

Goldman Sachs highlights one key industry theme this year: AI automation.  

 

Whether it’s Google’s Performance Max, Meta’s Advantage+, AppLovin’s Axon 2.0, or Pinterest’s Performance+, AI-driven ad algorithms are steadily eroding traditional ad budgets.  

 

This shift from “manual to machine-driven ad placement” makes advertising more data-driven and closed-loop.  

 

For brands, it means measurable ROI; for platforms, it signifies a business model where algorithms and advertisers coexist.  

3. Sector Breakdown: Meta and Google Show Greatest Resilience

At the stock level, Goldman Sachs maintains a positive rating on major tech platforms:  

• Meta (Target Price: $870)  Goldman believes Reels’ ad monetization has surpassed neutral levels, with user time spent up 17% YoY. The integration of AI content recommendations and the *Advantage+* ad engine is driving sustained revenue growth.  
• Alphabet (Target Price: $288)  Google is seen as the company with the “highest AI investment leverage.” Strong Gemini app growth, reaccelerated search business, and cloud revenue growth above 30% are key drivers. The search antitrust ruling was also milder than market expectations.  
• Pinterest (Target Price: $43) and Opera (Target Price: $24.5)  

These are viewed as “next-tier resilient picks post-AI transformation,” with Pinterest benefiting from shopping ad growth and Opera leading in the “AI browser wars.”

My Take

This report reveals an industry watershed moment—competition in advertising is no longer about creative content but about algorithm efficiency.  

 

As advertisers adopt AI tools to manage budgets, platforms must optimize traffic with AI.  

 

In this “dual-sided intelligent” structure, companies like Google and Meta, with first-party data and AI computing power, are building a new moat of “technological advantage + data dividend.”  

 

For investors, while ad industry cycles remain volatile, the long-term valuation logic has shifted to ROI on AI Capex.
