Global AdTech market growth to reach $2.14 trillion by 2035

The projected quadrupling of the market valuation signals a fundamental shift toward automated, AI-managed inventory that prioritizes measurable returns over traditional reach. For streaming providers, this means the technical stack must evolve to support real-time bidding and sophisticated first-party data strategies as third-party cookies disappear. As Google and Amazon consolidate their hold through Gemini and retail media ecosystems, independent players like Criteo and SpotX are carving out niches in performance marketing and programmatic video. This fragmentation forces a move toward omnichannel measurement. Watch for the adoption rate of agentic advertising in North America as a signal for how AI will automate the next generation of campaign optimization.

Google has moved aggressively to embed AI into its advertising stack, a strategy that directly fuels the projected AdTech market expansion. In April 2026, Google expanded AI Max to Shopping and Travel campaigns, marking one year since the product's initial launch, with the company calling it the fastest-growing AI-powered Search ads product. The expansion introduces text customization, Final URL Expansion, and Optimal Format Selection for Shopping ads, all powered by Gemini. Google's internal data from Q3 2025 showed that advertisers activating AI Max in Search campaigns typically saw 14% more conversions or conversion value at a similar CPA or ROAS, with campaigns relying heavily on exact and phrase keywords seeing uplift as high as 27%. A new feature called AI Brief lets advertisers provide rich contextual instructions in natural language to steer campaign messaging, rolling out first in English for Search campaigns before extending to Performance Max and Shopping.

The commercial implications of Google's AI advertising push extend well beyond its home market. In July 2025, Google brought its AI-powered marketing tools to India following the repeal of the country's so-called "Google tax", launching AI Max for Search Campaigns, Smart Bidding Exploration, shoppable connected TV ads on YouTube, and Performance Max Retention-Only Mode with Hindi language support. India's digital ad market is projected to grow over 20% year-over-year, reaching nearly $7 billion by the end of 2025, according to a Dentsu Digital Advertising report cited at the event. Google's gross ad revenue in India rose 11% year-over-year to 312.21 billion rupees ($3.6 billion) in fiscal year 2024, underscoring how AI-driven ad tools are scaling revenue in high-growth markets. The company also confirmed that ads would begin appearing within AI Overviews in India later in 2025, signaling a broader monetization of generative search surfaces.

The competitive landscape around programmatic and retail media continues to intensify as the AdTech market scales toward the $2.14 trillion projection. Google launched AI Max for Shopping as a one-click upgrade for retailers already running Shopping campaigns, using Merchant Center feed data such as fabric softness and material durability to match products against conversational queries. The move positions Google's retail media offering against Amazon Ads and Microsoft Advertising, both of which are investing in AI-driven commerce automation. For independent players like Criteo and SpotX, the consolidation of AI capabilities within walled gardens raises the stakes on differentiation through open measurement and cross-channel performance tools, particularly in where programmatic video inventory remains fragmented across multiple supply-side platforms.
