what pinterest dropped before cannes
Four announcements on June 17, one day before Cannes Lions opens. Only one of them is obviously interesting.
The obvious one: Ask Pinterest, a conversational shopping app in limited testing. Users type a query like "summer wardrobe under $200" and get AI-curated product results from across the platform. It's Pinterest's entry into the AI shopping interface race that Google AI Mode and TikTok Search are already running. It's early, so don't build your Q3 plan around it.
The other three announcements are where the actual paid media story lives.
the performance+ model change that's already live
Pinterest's Performance+ suite got a new underlying AI model and it's available globally right now. The difference is structural: the old model optimized at the ad level, selecting from the creative variants you'd designated as candidates. The new model evaluates the full set of creative assets and picks the specific variant most likely to perform for each individual ad impression — optimization at the asset level, not the campaign or ad level.
In testing, that change produced 7.5% more click volume compared to the previous model.
That's not a campaign structure change, not a new objective, not a bid strategy update. It's the same campaigns, same creative, same budget — and 7.5% more clicks from a model swap. If you have Performance+ campaigns running, this improvement is already working on your behalf. Pull a creative breakdown report in the next two weeks and you should start seeing it.
Pinterest also shipped enhanced creative reporting alongside this: more granular breakouts by variant and new ad review tools. The platform has historically been weak on creative diagnostics. That's getting fixed.
what mcp means for how agencies manage pinterest
Pinterest launched its Model Context Protocol infrastructure connecting the ad platform to third-party agentic tools. The alpha partner list: PMG, Pacvue, Dentsu, Havas, Innovid by Mediaocean, and Omnicom's Jump450. A beta opens to select US advertisers in July, with global rollout planned for Q4.
Here's why this is more than a technical footnote.
The actual reason Pinterest stays stuck at "test" budget for most DTC brands isn't ROAS — it's operational friction. Meta and Google live inside unified tools: Pacvue, Smartly, SA360, whatever your stack runs on. Pinterest is a separate login, a separate reporting pull, a separate set of decisions made on a different cadence. That friction compounds. When a platform requires more work to manage per dollar, it gets less budget. It has nothing to do with performance.
MCP removes that friction. When Pinterest campaign data — performance metrics, keyword insights, creative analytics — flows into the same tools that handle Meta and Google, the comparison happens automatically. CPM gaps get surfaced in the same dashboard. Budget reallocation doesn't require a Pinterest-specific meeting. The operational overhead drops, and the platform tends to get more budget when the overhead drops.
If you use Pacvue or work with Dentsu, Havas, or Omnicom, it's worth asking your Pinterest rep about early access to the July beta now.
business assistant and why the mobile piece matters
Business Assistant is an AI collaborator built into Ads Manager and the Pinterest mobile app. It surfaces trending topics as visual graphs rather than data tables — you see the actual Pins breaking out, not a spreadsheet of impression volume. It can recommend which Pins to promote and sends proactive notifications to your phone when a trend spikes or a campaign needs attention.
The notification angle is the underappreciated part.
Most performance managers check Meta and Google daily. Pinterest gets checked when someone remembers to check it. A push notification that says "this trend is moving, your creative matches, consider promoting this Pin" compresses the time between a trend spike and your response. That's not a small thing for an apparel or home goods brand running seasonal catalog campaigns.
The tool is in closed beta for US advertisers now, with a broader July rollout. It's not a standalone reason to activate Pinterest, but combined with the MCP infrastructure it closes a real workflow gap.
the business case you've been underestimating
Q1 2026: Pinterest hit $1.008 billion in quarterly revenue for the first time. Monthly active users reached 631 million, making it the fourth largest social advertising platform by user count.
Pinterest CPMs have historically run 30–50% cheaper than Instagram. The user base skews toward active product research — Pinterest users are saving products with purchase intent, not scrolling past them. That intent signal is different from discovery-mode behavior on Instagram or TikTok.
The combination — lower CPMs, commercial intent, an AI model that now delivers measurably better click volume, and agency tool integration on the way — adds up to a platform that has been systematically underbudgeted relative to its actual potential. The gap between "Pinterest as a moodboard" and "Pinterest as a performance channel" has been closing for two years. This week's Cannes announcements are Pinterest making its clearest argument yet that the infrastructure excuse is gone.
Whether your account produces the same 7.5% click lift as the testing data depends on your creative volume, your feed quality, and whether Performance+ is actually enabled. If you set up Pinterest campaigns 18 months ago and haven't touched them, the picture is probably worse than it should be.
The free Gromerce audit shows you where your media mix has structural gaps, including underoptimized platforms, in under 10 minutes.
Pinterest at Cannes is making a performance argument. The question is whether your account is set up to validate it.
