AI Becomes Advertising’s Biggest Growth Driver

Artificial Intelligence is rapidly transforming the advertising industry from a support tool into a core business driver. According to a new report by Redseer, AI is now emerging as one of the biggest growth engines for global advertising as brands, publishers, and platforms adapt to changing consumer behaviour and evolving digital ecosystems.

The report reveals that global advertising spends have already crossed the $1 trillion milestone and are projected to reach nearly $1.5 trillion by 2030, with digital advertising continuing to dominate industry growth.

At the centre of this transformation is AI  particularly generative AI which is fundamentally changing how advertising campaigns are created, optimised, targeted, and measured.

Redseer notes that AI is no longer viewed as an optional technology layer. Instead, it is becoming deeply integrated across the advertising value chain, helping brands improve efficiency, scale creativity, and personalise consumer engagement at unprecedented speed.

Generative AI is significantly reducing production bottlenecks by enabling faster creation of ad creatives across multiple formats, languages, and audience segments. This allows marketers to produce highly customised campaigns while reducing time, cost, and operational complexity.

The report also highlights a major shift in consumer behaviour. Today’s users spend nearly 6.5 hours online daily across multiple apps, devices, and digital environments. As audience attention becomes increasingly fragmented, advertisers are facing growing challenges in balancing reach with relevance.

According to Redseer, this fragmentation is creating what it describes as an “expensive mismatch” where brands may achieve visibility but struggle to deliver meaningful engagement.

To address this shift, the report identifies three major structural changes shaping the future of advertising:

• The decline of third-party cookies and legacy tracking systems
• The growing influence of AI across the advertising ecosystem
• Rising dependence on first-party data and direct consumer relationships

As privacy regulations tighten globally and consumers become more conscious about data sharing, brands are increasingly being pushed toward building stronger first-party data ecosystems. Clean rooms, cohort-based targeting, and owned audience relationships are expected to become central to future advertising strategies.

The report further suggests that AI-native companies could develop significant long-term advantages over businesses still dependent on traditional advertising systems. Areas such as targeting precision, campaign optimisation, and creative efficiency are likely to see the strongest competitive impact.

For marketers, the message is clear future growth will depend not only on media spending, but on how effectively brands leverage AI-driven decision-making, diversify digital investments, and build sustainable consumer data strategies.

Redseer also points toward strong momentum in India’s digital advertising market. Currently valued at around $11 billion, the sector is expected to grow to nearly $19–22 billion by 2030, driven by rapid internet adoption, growing digital consumption, and increased AI integration across marketing operations.

As digital ecosystems become more complex and consumer attention continues to scatter across platforms, AI is quickly becoming the technology that could define the next decade of advertising growth.
