The news: Meta and Google still account for 88% of mobile ad spending despite shifting user habits, per a Moloco report. But while advertiser attention remains firmly focused on Big Tech, those that diversify their media mix could increase financial returns as much as 214%. Our take: As audiences become fragmented across social media, advertisers are increasingly faced with the need to look beyond the big players—but with big tech still commanding attention, a balanced approach is key.

Consumers in Japan have been slow to embrace digital technology, but they are gradually warming to it. Recent data shows consumers are changing their online shopping and media consumption behavior.

CPM prices are rising YoY on every major social network in the US. But AI-driven ad products are helping advertisers see better outcomes, making it easier for them to justify the higher costs that come with more efficient targeting.

Pinterest reported a breakout Q2 2025 with $998 million in revenue, up 17% YoY—beating guidance and analyst expectations. Monthly active users hit an all-time high of 578 million, with profitability improving and ARPU rising globally. Gains were driven by GenAI tools like auto-collages, stronger commerce integration via Instacart, and a lean ad tech approach powered by Magnite. Pinterest’s ad business continues to grow steadily, with advertiser spending up and margins expanding to 25%. While still underweight in media plans, Pinterest is proving itself as a differentiated, performance-ready platform with rising traction among Gen Z and global users.

Time spent with social media is plateauing, but Gen Z and Gen Alpha are still platform-hopping. As Gen Zers steadily overtake millennials in terms of share, brands must understand the nuances of how each generation uses its platforms of choice.

The news: Reddit’s ad business is on a path of steady growth, with ad revenues expected to reach $1.8 billion this year and grow 29% to reach $2.5 billion in 2026, per a new WARC forecast. Brand participation on Reddit shows promising results: One organic brand post per week increases positive mentions by 3.5%. Our take: Though Reddit’s massive growth is partially attributed to its smaller reach, its ability to reach users that aren’t frequenting more popular platforms warrants investment, and a diversified approach combining Reddit’s unique community-driven base with larger platforms’ massive reach is key.

The news: While brands invest heavily in social media giants like Instagram and Facebook, smaller platforms are showing steady growth—indicating a future where ad opportunities go beyond the big players. While the Meta platforms make up an enormous 72.5% of US social network ad spending, smaller social media platforms are holding their own, experiencing growth at a similar rate to Meta. Our take: While advertisers shouldn’t discount the massive reach Meta offers, smaller players are increasingly valuable for driving results, especially as competition intensifies on larger platforms.

At Cannes Lions 2025, commerce media partnerships once again reigned supreme. Once the domain of digital shelf tactics and retail data, commerce media is now reshaping how brands show up across social platforms, connected TV (CTV), and in-store displays. This year’s festival offered a glimpse into a more integrated, AI-driven future—one where conversational ads, programmatic pipes, and real-world touchpoints blur the lines between media and purchase.

The news: Cannes Lions 2025 marked a shift in retail media strategy, with platforms like Pinterest and Reddit forging deeper ties with retailers. CVS announced a clean room data partnership with Reddit to allow targeting based on shared first-party data, launching a Sensodyne and Advil campaign this fall. Pinterest partnered with Instacart to enable shopping from pins and connect ad exposure to sales via closed-loop attribution. Our take: Social platforms are becoming full-funnel retail media environments. By fusing community context with purchase signals, these integrations aim to blend discovery and commerce in real time—paving the way for more data-rich, measurable campaigns.

The news: Pinterest is partnering with Instacart to allow advertisers to power their campaigns using the latter’s first-party data—a move that will enhance the value of both companies’ ad platforms while advancing Pinterest’s shoppable ambitions. Our take: Pinterest’s ability to engage the all-important Gen Z cohort, along with its role as a source of inspiration and product discovery, is making it a more strategic asset for brands and retailers. As economic uncertainty drives companies to be more careful with their ad dollars, Pinterest’s ability to reach audiences at every stage of their customer journey—now bolstered by access to Instacart’s first-party data—positions it as an even more valuable partner.

Jessopp will help Pinterest create new demand channels while scaling its programmatic abilities. Our take: Pinterest’s moves could better position it as a legitimate competitor in digital advertising and a promising growth area for influencers and marketers—giving the platform more legs against social commerce giants like Meta and TikTok.
