November 10, 2026 – PubMatic, a US-based digital advertising technology company, has reported growing use of artificial intelligence (AI) in its advertising platform. The company announced that more than 14,000 AI-powered advertising deals have been created on PubMatic to date. The milestone highlights the company’s expanding use of AI to support digital ad buying, although it does not mean that 14,000 complete advertising campaigns have been delivered.

PubMatic disclosed the figures in its third-quarter 2026 financial results, released on November 9. The company reported more than 14,000 AI-powered deals created to date, compared with more than 4,000 deals reported one quarter earlier. These figures describe the company’s reported milestones, not the number of new deals completed during the third quarter alone. The increase points to growing activity involving AI-powered advertising tools on PubMatic’s platform.

PubMatic also reported that its AgenticOS platform has supported more than 120 fully automated advertising campaigns since launching in January 2026. That number was above 80 at the end of the previous quarter. The platform uses AI to handle several advertising activities that traditionally require manual work, including campaign setup, audience selection, and performance monitoring.

An AI-powered advertising deal is different from a complete advertising campaign. In programmatic advertising, a deal generally defines advertising space available to buyers along with conditions such as pricing and audience targeting. AI can help create or manage these arrangements, while a complete campaign includes additional activities such as ad delivery, monitoring, and performance measurement. This means PubMatic’s 14,000-plus deals should not be confused with 14,000 finished campaigns or successful advertising results.

For businesses and marketing teams, AI-powered advertising tools could reduce repetitive work such as reviewing advertising opportunities, comparing audience data, and monitoring campaign delivery. This may leave more time for creative planning, customer relationships, and business strategy. However, automation does not make advertising quality less important. As ImiliCorp’s coverage of YouTube ad creative and ROI explains, advertising messages and creative quality can still influence campaign performance. Businesses should measure whether AI-assisted workflows improve results rather than assuming that faster processes always deliver better outcomes.

PubMatic highlighted a luxury watch campaign run by The Media Shop across six Asia-Pacific markets. According to the company, AgenticOS reduced campaign setup time from as much as 40 minutes to approximately eight minutes, saving around 80% of the preparation time. The campaign delivered about 9% more advertising impressions than planned, while ad viewability increased from 46.8% to 64.3%, an improvement of 17.5 percentage points. These company-reported results show the potential benefits of automated advertising in one campaign, but similar improvements are not guaranteed for every advertiser.

PubMatic also offers a Campaign Insights Agent that uses AI to review advertising performance each day and identify possible problems involving spending pace, ad delivery, targeting, and campaign results. Marketing teams can ask questions about these findings and consider suggested improvements while keeping control over important decisions. These insights may also help teams evaluate when a paid campaign is ready to scale. However, decisions to increase advertising budgets should still depend on accurate tracking, stable performance, and measurable business outcomes.

Alongside its growing AI advertising activity, PubMatic reported revenue of $79.6 million for the third quarter of 2026, an increase of 17% compared with the same period last year. PubMatic’s adjusted EBITDA, a company-reported measure of operating performance, reached $26 million, compared with $11.2 million a year earlier. Connected TV, mobile apps, and other emerging business areas represented approximately 64% of total revenue.

The growth of automated advertising also raises questions about how much control businesses should give to AI systems. PubMatic has introduced AgenticOS governance controls designed to help advertisers manage automated campaign activity through approval requirements, spending limits, and records of AI actions. However, these features do not remove the need for human oversight. Marketing teams should continue reviewing audience targeting, advertising quality, brand safety, and campaign spending to make sure automated decisions support their business goals.

For digital marketing agencies and businesses, PubMatic’s announcement shows how AI is becoming more involved in campaign planning, advertising purchases, and performance monitoring. However, faster campaign setup and higher advertising activity do not automatically lead to more sales. Marketers should also understand the difference between attribution and incrementality when measuring advertising impact. The long-term value of AI-powered advertising will depend on verified outcomes such as qualified leads, customer acquisition costs, sales, and business growth.

PubMatic’s latest figures suggest that AI-powered advertising is gaining momentum within its platform as businesses explore faster ways to buy and manage digital ads. However, growing adoption does not automatically guarantee better marketing results. The next challenge will be proving that automation can consistently improve advertising efficiency, reach the right audiences, and deliver meaningful business growth while maintaining transparency and human control.
