Four themes that defined Cannes Lions 2026

At A Glance

Cannes Lions 2026 marked a shift from talking about AI to deciding how it should guide marketing. Explore four themes shaping your planning for the rest of 2026: agentic AI, interoperable identity, curated activation, and outcome-based measurement.

Key takeaways:

  • Build agentic AI on trusted, permissioned data, connected identity, and decision paths that can be explained, tested, and measured.
  • Preserve flexibility with identity and data that work across partners and platforms without locking you into one commercial environment.
  • Use curation to bring trusted data, identity, and differentiated inventory together for better decisions at activation.
  • Measure across AI-influenced journeys and multiple partners to connect marketing activity with business outcomes.

If Cannes Lions 2026 had a bingo card, AI would have filled every square. But the week pointed to a bigger story: marketers are rethinking how identity, interoperability, activation quality, and measurement work together as the ecosystem becomes more connected and AI-driven.

As marketing changes, independence matters more. Brands, agencies, publishers, platforms, commerce media networks, and data providers need the flexibility to adapt without being forced into a single workflow, partner path, or technology stack. That requires trusted identity, interoperable data, strong governance, and infrastructure that supports choice across the ecosystem.

Here are the themes that defined Cannes Lions 2026.

1. Agentic AI shifted the conversation from content creation to how marketing decisions get made

Agentic AI shifted the Cannes conversation from content creation to the way marketing decisions get made. Marketers are now asking how AI systems recommend actions, build plans, optimize spend, and shape which brands appear in AI-influenced environments. That shift puts understanding and managing AI-driven decisions at the center of the AI conversation. Marketers need to know what data an AI system is using, which signals it may prioritize, how those signals are governed, and whether the decision path can be explained, tested, and measured.

Agentic AI will raise the stakes for the data collaboration layer because connected data can influence training, decisioning, optimization, activation, and measurement. That makes governance, transparency, and control more important across every environment where data is used.

  • Brands need confidence that AI-informed decisions reflect accurate and unbiased customer understanding.
  • Agencies need transparent inputs they can defend across clients.
  • Platforms and media owners need high-quality signals that improve performance without creating more fragmentation.
  • Publishers need clear ways to protect the value of their content and audiences as discovery becomes more automated.

“Everyone wants to talk about agentic AI, but the differentiator is the quality, governance, and connectivity of the data behind it. The organizations that will get the most value from agentic AI are the ones that have invested in trusted identity, strong governance, and interoperable data foundations that allow them to activate, measure, and maintain control at scale.”

ExperianBudi Tanzi, SVP, Product

Agentic AI needs trusted, permissioned, and well-connected data. It needs identity that can support a consistent view of people and households across environments, and governance that gives marketers confidence in how data is connected, activated, and measured.

2. Interoperability is the foundation for flexibility and trust

Interoperability gives marketers the flexibility to work across partners, platforms, and channels without being locked into one commercial environment. At Cannes, it became clear that trusted infrastructure is now central to how teams collaborate, activate audiences, and measure performance.

Cannes also made clear that flexibility has become a business requirement. Marketers are working across more partners, channels, and collaboration environments. Marketers also need to trust the infrastructure underneath it. That means clear governance, aligned incentives, transparent data use, and the ability to measure performance without being locked into one commercial environment.

As the market becomes more connected, teams need identity and data infrastructure that can move across the ecosystem without limiting choice. Interoperability isn’t enough on its own.

  • For brands, this starts with making first-party data more usable and scalable across the marketing ecosystem. Customer data becomes more valuable when it can be resolved, enriched, expanded, activated, and measured in privacy-conscious ways. That flexibility helps brands turn owned signals into scalable audience strategies without losing control over how data is used.
  • For agencies, it creates more efficient ways to plan, execute, and measure across clients. For commerce media networks, publishers, platforms, and media owners, it helps valuable signals move into market in more usable, governed, and scalable ways.

“The marketers making the most progress today are the ones building flexibility into their data and identity strategies. Interoperability gives them the freedom to work across partners, adapt to change, and trust how audiences are understood and activated.”

ExperianKevin Dunn, Chief Revenue Officer

An independent identity foundation can help connect these environments without forcing every partner into one workflow. Teams need the ability to work across agencies, platforms, publishers, commerce media networks, clean rooms, and media channels while maintaining a consistent view of their audiences, understanding how data is being used, and measuring performance across partners.

3. Curation is a path to better decisions

Curation gives buyers and sellers a more intentional way to bring data and media together. At Cannes, the strongest conversations focused on how better signals, supply, and decisioning can improve performance at the point of activation.

  • For brands and agencies, that means media strategies that are easier to explain, optimize, and measure.
  • For publishers, platforms, and media owners, it creates new ways to package differentiated inventory with high-quality data.
  • For commerce media networks and data providers, it can extend valuable audiences into more scalable activation environments.

“The future of marketing belongs to organizations that prioritize data and audience activation at the centerpiece of every conversation.”

ExperianChris Meredith, Head of Audience Activation

This is where curation becomes more than a media tactic. It becomes a way to improve decision quality at the point of activation. When trusted data, identity, and supply come together, marketers can reduce waste, improve relevance, and bring more confidence to each activation decision.

4. Measurement has to account for an AI-shaped customer journey

Measurement remained a consistent theme throughout the week, but the conversation was broader than campaign reporting. Measurement now has to account for more decision points, partners, and AI-shaped interactions. Marketers need to understand how investments influence growth, sales, visits, and other meaningful actions across a journey that may not begin with a search, site visit or traditional ad exposure.

  • Brands need to understand which investments are driving customer growth, sales, visits, or other meaningful actions.
  • Agencies need proof they can defend across clients and channels.
  • Publishers, platforms, commerce media networks, media owners, and data providers need clearer ways to show the value they create as attention, discovery, and activation become more fragmented.

“Marketers are under pressure to prove outcomes, not just report performance. As measurement becomes more fragmented, organizations need a stronger foundation built on identity, interoperable data, and outcome-based measurement.”

ExperianAli Mack, VP, AdTech Sales

The measurement challenge now is about building a trusted view of performance across more decision points, partners, and AI-shaped interactions. It also requires confidence that measurement is grounded in consistent identity, governed data, and infrastructure that supports transparency across the ecosystem. That level of proof depends on stronger connection across planning, activation, and measurement. When teams use a consistent identity foundation and responsible data practices across the journey, they can move beyond delivery metrics and start understanding what worked, where it worked, and how to apply those insights to the next decision.

FAQs

The main marketing themes from Cannes Lions 2026 were agentic AI, interoperability, curation, and outcome-based measurement. Together, these themes point to a marketing ecosystem where identity, governed data, and partner flexibility are becoming central to how teams plan, activate, and measure.

Marketers are talking about agentic AI now because AI is starting to influence more than creative and workflow efficiency. It’s beginning to shape recommendations, planning, spend decisions, consumer actions, and brand visibility in AI-shaped environments.

Identity matters more as AI becomes part of marketing decisioning because AI systems need accurate, permissioned and connected data to guide useful decisions. A consistent identity foundation helps marketers understand people and households across environments, test decision paths, and measure outcomes with more confidence.

Experian helps marketers act on these Cannes Lions 2026 themes through our identity foundation, data capabilities, and measurement approach that help marketers connect planning, activation and measurement across partners. Experian helps brands, agencies, publishers, platforms, commerce media networks and data providers build interoperable strategies that support flexibility, transparency, and control.

After Cannes Lions 2026, marketers should assess how their identity, data, activation, and measurement strategies work together across the partners they use today. The next step is to identify where fragmentation limits decision quality, audience activation, or proof of performance, then build a more connected approach across the ecosystem.

Forrester Study—how identity resolution can help marketers prepare for data deprecation and improve data quality

Marketers are under more pressure than ever before to prove ROI and efficiency of marketing activities in relation to business performance. On top of that, there are new privacy regulations and uncertainty around what new technologies will have to be implemented in order to replace the granular level targeting and measurement the industry historically has used third-party cookies for. It’s clear marketers are going to need the right tech stack and partners to continue to prove their team’s efficacy. We recently partnered with Forrester Consulting to evaluate the current state of customer data-driven marketing and surveyed over 300 global marketing decision makers at the brand and agency levels. We found that marketing is facing increased demands today, insights from the study include:Consumers expect brands to deliver engaging experiences across highly fragmented journeys. Seventy-two percent of decision-makers reported that customers demand more relevant, personalized experiences at the time and place of their choosing. Marketing runs on data, but the rules governing customer data usage are changing quickly. More than 70% of study participants stated that consumer data is the lifeblood of their marketing strategies, fueling the personalized, omnichannel experiences customers demand. These demands paint a challenging picture. Just as marketers are poised (and tasked) with delivering greater value to their organizations and customers, the ground rules are changing and threatening their ability to deliver. Indeed, 62% of respondents said that the forces of data deprecation will have either a “Significant” (40%) or “Critical” (21%) impact on their marketing strategies over the next two years. Effective identity resolution can help brands prepare for data deprecation challenges Marketers face a daunting landscape, but they can leverage the data, technology, and processes that comprise identity resolution to address business objectives, combat ecosystem complexity, and future-proof customer engagement efforts. By utilizing identity resolution, marketers will be able to match and connect multiple identifiers across devices and touchpoints. This allows for a cohesive, omnichannel view that enables brands to continue to deliver personalized and contextually relevant messages throughout the customer journey and without the use of cookies. The identity graph is the underlying infrastructure that defines connections between the numerous, fluid, and disparate identifiers created during moments of consumer engagement, turning disparate signals into addressable and actionable steps. These connections enable brands to bolster their ability to gain deeper customer insights and power audience building, attribution, and connected measurement. Identity resolution encompasses a wide range of capabilities that support an equally diverse set of marketing use cases. These include the targeting, personalization, and measurement of both known and pseudonymous audiences in the offline and digital worlds, which enables marketers to improve customer data management, drive more effective personalization, and gain insights and efficiencies through measurement across touchpoints. By taking the time to vet the privacy procedures and data collection processes of identity solutions you can reduce your regulatory risk and maintain customer trust. In an open-ended survey response, a marketer shared, “We’ve found that users are willing to volunteer data when they understand what it’s being used for and are asked for clear consent.” Finding the right partners to help navigate the changes The scramble to find an alternative to third-party cookies has slowed down since Google announced they will be delaying their cookie removal until late 2023. However, this gives marketers a unique opportunity to take advantage of the additional time and feel more prepared and confident in their solutions. With the delay, marketers can now test ID solutions and compare apples to apples with data from the third-party cookie while it’s still active and addressable. Test and find a solution that works now, so there are no surprises once cookies have finally made their way out the door in 2023. At Tapad, a part of Experian, we’ve developed a solution that provides agnostic interoperability for the myriad of cookieless identifiers emerging in the market. As a new module in the Tapad Graph, Switchboard will connect traditional digital identifiers to cookieless IDs to support the entire ad ecosystem with privacy-safe future-proof identity resolution.

Uncovering hashed email: you may be sitting on a goldmine of customer data and don’t even know it

Email hashing was originally intended to be used as an email security feature that has ended up being a very powerful marketing tool. A hashed email is a cryptographic function that changes an email address to a random code which can be used as an anonymous customer identifier. This code is privacy-safe and cannot be traced back to the customer’s email address. However, this hashed email can function like a digital passport that traces every behavior and action a customer takes when logged into an account that is authenticated with an email, making hashed emails a goldmine for customer data. Today emails are used across traditional publishers and within the CTV ecosystem; tying them to more consumer touch points than ever before. Why the emphasis now? Cookies are on their way out the door and have been the primary way that many marketers have tracked their existing and potential customers. In order to replace this granular level of data, marketers are likely going to need multiple solutions. With so many cookieless solutions and IDs appearing in the marketplace, the mapping of the customer journey is bound to be fragmented. Relying on first-party data, such as hashed email, is just one way to reduce that fragmentation; as it can serve as an authenticated starting point for cross-device identity resolution that can be leveraged for targeting, personalization and measurement. How can Tapad + Experian help? Tapad + Experian’s Hashed Email Onboarding is a privacy-safe way to connect consumer email addresses to their related digital devices and other digital identifiers through high precision probabilistic identity. By onboarding hashed emails and incorporating them within your Tapad Graph file you can: Build a more holistic view of individuals and households and their relationship to email addresses in your first-party data set Leverage these relationships for increased cross-device scale for targeting Employ personalization tactics at the household or individual level across devices Create new audience segments and look-alike models for cross-channel activation Design more inclusive measurement and attribution for customer journey mapping Tapad, a part of Experian has built a hashed email onboarding product feature that works with the existing flexibility of The Tapad Graph to deliver the most holistic consumer view, combined with the attributes you need, in the structure that works best for your business objectives.

Connect the disconnect in your CTV universe

The result of epic shifts from traditional cable to streaming television, the CTV ecosystem is experiencing compounded fragmentation, making it challenging for marketers to leverage in the most effective way for both activation and measurement. Heralded as the hot new household level device for highly engaged viewers, CTV brings massive opportunities for brands to move users down the funnel and incorporate CTV into their attribution modeling post-campaign. Leveraging CTV IDs within a cross-device identity resolution strategy can yield big benefits if you know how to do it right. Check out our breakdown of today’s CTV landscape to help you better understand how and what you can leverage for activation and measurement in the streaming-verse today. Addressability and attribution Not all CTV devices and IDs are addressable; or have ad slots for biddable inventory for advertisers. For example, Apple TV devices and Apple TV + are not ad supported, but could still appear within an identity graph for measurement purposes; helping understand customer behavior and habits, which can inform marketing strategies. Having a household to individual view that’s as inclusive as possible can provide valuable insights. CTV identity strategy Whether or not CTV devices or apps are addressable for advertisers, they can bring immense value when leveraged as part of a holistic identity resolution strategy. As a household level device with user authentication it can provide marketers a top-down view; unlocking household:individual targeting opportunities and unification of IDs at both levels for frequency management and customer journey mapping Get started with us Tapad, part of Experian, offers CTV ID onboarding and extension to our CTV ID Universe as a part of The Tapad Graph suite of products.
