Rich answers these questions:
1. Now that you’re leading Walmart Connect alongside International advertising and Sam’s Club Connect, what does “one connected global advertising ecosystem” actually look like operationally — and how soon will advertisers feel the difference?
2. What capabilities or playbooks from Walmart Connect US are you most excited to bring into international markets, and conversely, what can Connect and international teach the core US business?
3. This is Sam’s Club Connect’s first time at Cannes Lions — what’s the headline message you want advertisers and agencies to walk away with?
4. How does a presence at Cannes fit into COnnect’s broader growth strategy, especially as it scales offerings like in-club, Omni Experiences, and audio/fuel screen ads?
5. The industry conversation is shifting from impressions and ROAS toward broader business outcomes — what does that shift look like in practice for how Walmart structures its advertiser partnerships?
6. What’s the biggest misconception brands still have about what “success” should look like in retail media today?
7. How does Walmart’s first-party data — and Sam’s Club’s membership model specifically — change the kinds of insights and long-term value you can offer advertisers compared to transaction-only data?

Mark answers these questions:
So Mark, let’s kick it off with the big news that completely shocked the industry. At recent industry events, you took the stage and did what almost no other Retail Media Network does: you completely exposed Costco's full technology stack—revealing every single identity vendor, DSP, and clean room provider you use. Why did you make the deliberate choice to embrace absolute transparency, and how has that transparency directly influenced ad spend from skeptical brands and agencies?
Transparency builds the ultimate trust, no doubt. Now Mark, you have a beautiful phrase that we absolutely love: "Retail media at Costco exists to accelerate merchandise sales." You maintain a strict structural hierarchy where merchandise velocity and member loyalty sit firmly at the very top. If a digital ad campaign doesn't help move a physical pallet of product or reinforce the value of a membership card, it simply doesn't belong in your ecosystem. How do you enforce this "merchant-first" philosophy when national brand managers come in with legacy KPIs focused entirely on vanity ad metrics?
 Pallet velocity over vanity metrics every single day of the week! Mark, let's talk about your unique "Last-Mover Advantage." While other networks rushed to stand up brittle, overly complicated platforms out of the gate, Costco spent its time quietly observing the market and engineering a robust private data cloud from the ground up. How did waiting and prioritizing a clean, unfragmented data foundation allow you to completely leapfrog the "black box" reporting traps that have frustrated CPG teams for years?
That backend data foundation is the real secret sauce. Let’s look at a highly disruptive offsite capability you recently rolled out: Google Product Listing Ads (PLAs). This isn’t typical offsite audience extension or standard Connected TV (CTV) storytelling; you are moving Costco's first-party retail media directly into Google Shopping search. For the brands listening, why does leveraging Costco’s high-intent audience data inside Google's open shopping engine radically perform better than a brand trying to buy those generic keywords on their own?
Tying high-intent open web search to verified warehouse data is a game-changer. Mark, let's look at what you call "In Real Life" (IRL) Activation—the third pillar of your omni-channel media strategy. Costco's physical club warehouses are legendary for their high-frequency, massive-basket foot traffic. How are you taking real-world, physical-store signals—everything from fuel pumps to warehouse digital screens—and dynamically connecting them back into a single, cohesive digital loop?
Physical-digital loop integration is exactly where the massive volume lies. Mark, let's talk about building a Composable Architecture. Your technical setup is intentionally designed as a cohesive orchestration layer where identity, activation, and clean room metrics can evolve independently without disrupting the core business. Why should global CPG technology heads stop trying to build rigid, custom end-to-end stacks and instead adopt Costco's modular, composable blueprint?
Composable modularity is the ultimate future-proofing play. Mark, we are rapidly entering the "Agentic Era" of commerce, where autonomous AI agents are beginning to manage complex segmentation, path recommendations, and real-time budget optimization behind the scenes. How is Costco utilizing advanced AI orchestration layers to cut through operational friction, making your complex, multi-partner systems intuitive and highly usable for brand teams?
AI-driven demand generation is going to separate the winners from the laggards. Let's double-click down on The Merchant-Media Collaboration Loop. In many traditional retail environments, the media network operates as an isolated, outside fiefdom that frequently causes friction with the actual category merchants. At Costco, you have deliberately fused media capability directly into the merchandising lifecycle. Can you take us under the hood of that internal relationship? How do your media specialists work harmoniously alongside the warehouse buyers to drive mutual top-line growth?
Tying the merchant loop directly to the ad stack is how you achieve sustainable scale. Mark, Costco is world-renowned for its hyper-curated, disciplined product assortment—you don’t carry 50 versions of an item; you carry the absolute best value selections. How does this strict, limited-SKU club environment fundamentally change the digital shelf auction on your onsite properties? Does a highly curated box mean that retail media real estate on Costco is infinitely more valuable and defensive for an incumbent brand?
Highly curated spaces demand highly precise execution. Alright Mark, final question for today, and we want to send our global practitioner audience home with an absolute golden nugget of advice. If you could look a corporate CPG Chief Customer Officer or Head of Sales dead in the eye today, what is the single biggest "reality check" or piece of blind-spot advice you can give them to help them stop treating retail media as a lower-funnel marketing tax and instead unlock true, closed-loop incremental volume this quarter?

Ali & Tim answer these questions:
So Ali, let’s kick it off with you on a massive macro trend. We just read Nik Modi's latest RBC Capital report, Modi’s Musings Volume 4, and theme number one is that Cultural Relevance > Brand Equity—meaning scale alone doesn’t protect you anymore; you have to turn online platforms into an active "economic substrate" for identity and transaction flow. How is Instacart evolving its ad tech stack to let legacy CPG giants quickly move at the speed of a viral TikTok trend or cultural moment, turning immediate social media inspiration into a converted grocery basket? 
That speed to conversion is everything. Tim, let’s talk about some news you announced at Cannes this week. Let’s start with your AI Shopping assistant. What makes Instacart’s AI assistant different?
As consumers look to collapse choice complexity because of low mental energy and rising anxiety, the visible shelf is shrinking from 50+ items down to 1 or 2 AI-curated recommendations. How does this radically compressed digital real estate change your ad business strategy and Joint Business Plans with brands? You mentioned you're intentionally not running ads in AI experiences yet. Walk us through how you’re thinking about that. 
Jumping back to the news…Immersive Feed feels like a direct response to how consumers are already discovering food on social media. How do you make sure that experience feels additive and not just like another ad unit? Does this foreshadow more to come with media publishers and creators? 
And for Ads Studio – is that essentially opening up Instacart's own marketing engine to brand partners? What made you confident enough in that internal capability to turn it into a commercial offering?
Tim, let’s pivot to New Revenue Streams and Business Models. CPG brands are desperately trying to evolve from old-school, unit-driven transactional models toward ecosystem-based monetization. With Instacart Caper Carts rolling out smart screens right into the physical brick-and-mortar aisles, you guys have built a literal physical-digital loop. How should brands rethink co-created, real-time physical store experiences using your connected hardware?
Connected hardware in the physical aisle is the ultimate frontier. Ali, we can't talk about Cannes Lions without talking about Closed-Loop Measurement. Marketers are completely burnt out on self-attributed platform metrics. Instacart’s entire value proposition is anchored on receipt-level, purchase-verified deterministic truth. For the brand marketers listening who are caught in the "Validation Trap," what does mathematically clean, independent attribution look like over the next three years, and how does Instacart enforce it?
If it doesn't move actual volume off the shelf, it’s just noise. Tim, looking at your front-row seat to enterprise sales, what separates the North Star CPG brands—the progressive companies that are aggressively growing their volume share on Instacart right now—from the legacy laggards who are still trying to run 20-year-old, static, distribution-only playbooks? What core corporate competency or operational rhythm allows them to win?
Incredible, provocative insights. Now, before we pack up the mics and head out onto the Croisette for a glass of rosé, we have to save a special final question. Cannes Lions is famously the birthplace of massive, landscape-shifting partnership announcements and enterprise platform reveals. Ali, Tim... what do you guys have cooking up under the hood for Instacart that you can uniquely share with the CPG Guys community live today?
