Key Trends & Drivers in Global Digital Ad Spend
The global digital advertising ecosystem is moving from a phase of rapid expansion to one defined by operational sophistication, regulatory reset, and heightened accountability expectations. Markets worldwide are integrating AI into campaign workflows, accelerating monetisation across video and retail media, and adapting to privacy-driven changes in data governance. These shifts are reorganising platforms, formats, and buying models around measurable outcomes, compliance readiness, and audience engagement. Generative AI, retail media networks, and connected TV will influence spending patterns, yet long-term value will be determined by trust, transparency, and responsible innovation. Regions that align regulatory clarity, advanced ad-tech capability, and dense digital consumer bases are positioned to lead the next wave of growth.

1) Generative AI reshapes digital advertising operations and creative production
Generative AI is being integrated across digital ad production, targeting, and measurement processes globally. Platforms such as Meta, Google, and Amazon are embedding generative tools to automate creative versioning, audience insights, and campaign planning. For instance, Google Performance Max now uses AI to generate ad variants based on asset inputs, while Meta’s Advantage+ suite leverages AI to test and optimise creatives at scale.
• Advertisers are seeking efficiency in campaign management and creative production, particularly as digital campaigns become more fragmented across formats and platforms. AI offers a solution by enabling dynamic personalisation, reducing production cycles, and scaling experimentation.
• Adoption is expected to intensify as AI tools become embedded in standard campaign workflows. However, regulatory scrutiny over AI-generated content and transparency will influence platform design and advertiser uptake. The competitive advantage will tilt toward players that integrate AI within privacy-compliant and brand-safe environments.

2) Retail Media Networks (RMNs) evolve into full-funnel platforms
Retail media has become the fastest-growing segment in global digital advertising. Companies like Amazon Ads, Walmart Connect, and Carrefour Links are expanding capabilities beyond sponsored listings into video, display, and offsite advertising. Global retailers are now bundling first-party data access, on-site placements, and media execution to position themselves as full-funnel solutions.
• The deprecation of third-party cookies and rising demand for commerce-linked ROI have driven brands to seek media inventory with embedded purchase signals. Retailers, with their rich first-party shopper data, offer a privacy-safe alternative to traditional cookie-based targeting.
• RMNs will likely consolidate their position as core performance channels, with more global retailers investing in self-serve ad platforms and DSP integrations. Expect tighter integration with social and video ecosystems, further blurring the lines between content, commerce, and media.

3) CTV and ad-supported streaming open new video monetisation layers
Connected TV (CTV) and ad-supported video on demand (AVOD) are becoming central to global media plans. Netflix, Disney+, and Amazon Prime Video have launched ad-supported tiers, while local players such as ITVX (UK), TF1+ (France), and JioCinema (India) are building hybrid monetisation models. CTV is attracting both brand and performance budgets due to its lean-back format and household-level targeting.
• Consumer migration from linear to streaming has accelerated, especially post-pandemic. Subscription fatigue and economic pressure are nudging users toward free or subsidised content, creating supply for ad inventory. Advertisers are seeking premium video environments with measurable outcomes.
• The ecosystem will mature as measurement and targeting improve. Expect growth in programmatic CTV, partnerships between telcos and streamers, and unified measurement frameworks to validate cross-platform reach. Global ad spend on streaming platforms is set to rise, but fragmentation will demand platform-agnostic planning tools.

4) Walled gardens maintain control, but open web and retail media pressure grows
Google, Meta, and Amazon remain dominant recipients of global digital ad spend, but their share faces increasing competition from retail media networks, independent publishers, and commerce-driven ad tech. Apple’s SKAdNetwork and Google’s Privacy Sandbox are also reshaping how campaigns are measured within closed ecosystems.
• Advertiser fatigue with opaque measurement and limited control is pushing demand for more transparent, open-web solutions. At the same time, platforms are fortifying their ecosystems with exclusive tools and data to retain spend.
• The balance of power will likely shift incrementally. While walled gardens retain efficiency and scale, the open web will grow with contextual solutions and new identity frameworks. The next frontier will be interoperability tools that allow advertisers to operate across ecosystems without compromising compliance or performance.

5) Sustainability and responsible media buying rise as brand priorities
Global brands are increasingly factoring sustainability and ethical media placement into digital ad planning. Initiatives such as GroupM’s carbon calculator and ad net-zero commitments by agencies are gaining traction. Advertisers are reviewing supply chains to minimise emissions from programmatic buying and avoid misinformation or non-brand-safe placements.
• Stakeholder pressure, regulatory developments, and investor focus on ESG performance are compelling brands to re-evaluate media practices. Media buyers are seeking to align spend with corporate sustainability targets.
• Sustainability will move from a CSR checkbox to a procurement KPI. Expect broader use of emissions calculators, publisher audits, and exclusion lists. Transparent, verifiable frameworks will determine how media suppliers compete for brand dollars.

Competitive Landscape: Global Digital Ad Spend
The competitive environment for digital advertising is intensifying as legacy tech platforms, commerce players, content owners, and ad-tech startups converge around new monetisation opportunities. While Google, Meta, and Amazon still dominate spend allocation, rapid expansion in CTV, retail media, and AI-powered tools is broadening the field. The market is witnessing consolidation in some areas, experimentation in others, and a reconfiguration of alliances based on data access and campaign performance.

Competitive Intensity is High Across Segments
Digital ad competition is no longer confined to traditional tech platforms. Retailers (e.g., Walmart, Carrefour, Reliance), streamers (e.g., Netflix, Disney+, JioCinema), and commerce marketplaces (e.g., Shopee, Mercado Libre) are building ad businesses. The proliferation of self-serve ad platforms and API-based media buying is making market entry easier, intensifying spend fragmentation.
• Google remains strong in search and programmatic display, but faces new scrutiny around data dominance and AI use.
• Meta continues to draw performance spend via Instagram and Reels, but TikTok is steadily gaining share, especially in younger cohorts.
• Amazon’s advertising division has expanded into upper-funnel video and offsite display, while Apple and Microsoft are growing niche advertising arms via native placement ecosystems.

Key Players and Emerging Challengers
The core global players such as Google, Meta, Amazon are being challenged on multiple fronts. Retail media is led by Amazon globally, but Walmart Connect, Target Roundel, and Instacart in the US, as well as Carrefour, Mercado Libre, and Alibaba internationally, are scaling fast.
• In video, YouTube remains dominant, but Netflix, Roku, Samsung Ads, and Disney+ are carving out addressable video segments.
• In ad tech, The Trade Desk and Magnite have strengthened their presence in CTV, while smaller firms like PubMatic, LiveRamp, and Innovid are innovating on identity, measurement, and creative delivery.
• TikTok and Snap remain relevant for social and mobile-first formats but face regulatory and brand safety headwinds.

Strategic Partnerships and Acquisitions Reshape Capabilities
Recent years have seen a flurry of M&A activity and alliances:
• Microsoft acquired Xandr to deepen its ad tech stack and integrate LinkedIn data into wider campaigns.
• Netflix partnered with Microsoft as its exclusive ad-tech partner for its ad-supported tier, underscoring the need for trusted intermediaries in new ad environments.
• Instacart partnered with Roku to merge commerce and video ad attribution, showcasing cross-channel innovation.
• Trade Desk launched OpenPath to bypass traditional SSPs and provide direct publisher access, reshaping the open web supply chain.
These moves signal a broader trend where data access, measurement trust, and inventory control are more valuable than scale alone.

Regulatory Changes Are Reshaping Strategy and Compliance
Globally, privacy and competition laws are altering how platforms collect, use, and monetise data:
• The EU’s Digital Markets Act (DMA) and Digital Services Act (DSA) have required major platforms to overhaul data transparency and user choice mechanisms.
• The U.S. saw enforcement action on data transfers and ad targeting practices, including FTC focus on dark patterns and children’s data.
• APAC regulators are increasingly harmonising privacy frameworks with global standards, influencing how multinationals run campaigns.
As regulation tightens, advertisers and platforms are investing more in consent management, clean rooms, and contextual targeting to maintain performance without breaching compliance boundaries.

Outlook on Market Evolution and Strategic Positioning
Over the next 2–4 years, the global digital ad landscape will likely be defined by a few core trends:
• Platforms that can unify audience insights, media execution, and attribution across formats will capture greater share.
• Retailers with scalable ad platforms and trusted first-party data will emerge as default performance partners.
• CTV will formalise its role in brand + performance mixes, especially as global media companies improve ad load and targeting.
• AI-native tools and privacy-centric architecture will separate scalable operators from legacy players reliant on cookie-era models.
Competitive advantage will rest on three pillars: data integrity, omnichannel orchestration, and regulatory alignment. As economic and social pressures mount, stakeholders will reward partners who combine innovation with accountability and measurable return on spend.
