Cannes Lions 2026 — advertising's biggest awards (opened June 22)
Cannes Just Killed the AI Hype. Proof Is the New Flex.
Cannes Lions — advertising's biggest awards — opened June 22, and the juries' verdict was blunt: using AI no longer wins anything on its own; you have to show it improved a real business result. Publicis Groupe, one of the world's biggest agency groups, urged the industry to move “from AI demos to demonstrations of real business proof.” In practice the bar just moved: “we used AI to make this” no longer lands, but “we used AI and bookings rose 12% over last month” wins the room. The takeaway for marketers: using AI is now table stakes — proving it moved your main number is the new flex. (Cannes Lions 2026 runs June 22–26; marketing roles requiring AI literacy are up 113% year-over-year, yet only 4% of marketers list AI skills. Source: LinkedIn Economic Graph, Jun 2026.)
A Good First Step Today
Pick your most “AI-powered” campaign from this quarter and write one sentence: the business number it moved, versus what it would have done without. If you can't fill that blank yet, that's the most valuable hour you'll spend this week.

Meta
Meta Is About to Pass Google in Ad Revenue — a First
eMarketer projects Meta at $243B in 2026 global ad revenue versus Google's $240B — the first time Google loses the top spot. Meta is growing about 24% this year versus Google's roughly 12%, driven by Advantage+ automation. Spend is flowing to whoever pairs scale with automation and provable return, so pressure-test your channel mix before next quarter's budget locks.
Adobe & LinkedIn
Adobe and LinkedIn Launch Free “AI Essentials for Marketers”
Free, short courses (June 16) in four role-based paths, each finishable in 2 to 3 hours, on LinkedIn Learning and Adobe Experience League, in 47 languages; it debuts at Cannes. Marketing roles requiring AI literacy are up 113% year-over-year, yet only 4% of marketers list AI skills. A free, fast way to close the exact skills gap Cannes is calling out — and to back “we used AI” with real craft.
NVIDIA
NVIDIA's Partners Bring Agentic Ad Production to Cannes
At Cannes Lions (June 22), NVIDIA and its agency and ad-tech partners showed AI that builds and adapts ad creative on its own, at scale — moving from one-off demos to always-on systems that spin out many versions from a single master ad. When making lots of versions gets cheap, your edge shifts to judgment and, as Cannes just said, to proving the work actually performs.
Useful Tool This Week
AdCreative.ai
WATCHFree trial (7-day, credit card required — not a forever-free tier)It scores your ad creative from 0 to 100 and predicts how it will perform before you spend a cent running it.
- Cannes just said prove it; this lets you pressure-test creative on a number, not a hunch, before it goes live.
- It's a 7-day free trial that needs a credit card and auto-charges if you don't cancel — not a forever-free tier. Set a reminder.
- Score three versions of your next ad, run the highest-scoring one, then note the real result against the score it gave you.
The creative scoring helps us pick which ad to run before we spend — it's become a quick gut-check on every batch. — Verified G2 reviewer, performance marketer
A Prompt Worth Saving
Cannes just made “we used AI” a non-answer. Paste in one campaign and the AI tool you used, and get a one-page proof plan: the one metric that matters, a fair baseline, what to measure, and a 3-sentence result you can show a boss or client. Built to help you prove real impact — an honest before-and-after, with no inflated multipliers.
You are a sharp, honest marketing analyst. Help me prove whether one campaign actually worked. What I will give you: The campaign: [what it was + channel] The AI part: [the AI tool or feature I used] The goal: [the ONE business number that matters - sales, leads, bookings, signups] What I have: [results so far + any before numbers] Constraints: [budget, timeframe, audience size] Give me back: 1) The single metric to judge this on - and why it beats vanity metrics 2) A fair baseline to compare against (last period, a holdout, or an A/B) 3) Exactly what to measure, and for how long 4) The math to calculate real lift, in plain numbers 5) A 3-sentence result I can show my boss or client - honest, no inflated claims If my numbers cannot prove it yet, tell me what to collect next.
Why it works
- It forces one real business metric — the thing Cannes (and your boss) actually want to see.
- A baseline turns “it felt like it worked” into a number you can defend.
- The 3-sentence result is what wins the room — short, honest, and repeatable.
