Brazil’s digital advertising economy continues to thrive, driven by retail media investment, growing video ad spend, and slower social ad spending. This report explores trends shaping Brazil’s digital advertising landscape in 2025.​

A new four-day format for Amazon’s tentpole event will shake up the playing field.

The Q2 performances of Amazon, Walmart, and Target illustrate the retailers’ diverging fortunes as shoppers reassess their spending priorities. While uncertainty is funneling more dollars toward Amazon and Walmart, customers are steering clear of Target—due both to a lackluster assortment and frustration over its diversity, equity, and inclusion (DEI) flip-flopping. Walmart and Amazon are pulling ahead as their relentless focus on value—in the form of speed, selection, and convenience—make them the first stop for shoppers buying everything from essentials like groceries to discretionary items like beauty and apparel. That leaves Target’s new CEO, Michael Fiddelke, with the unenviable task of having to turn the retailer around just as tariffs threaten its bottom line and undermine its core discretionary business.

Amazon shrugged off tariff concerns in its Q2 earnings report, after reporting growth ahead of expectations. But the retailer’s Q3 forecast was murky, suggesting that while consumer demand remains resilient, uncertainty from tariffs and trade policy—along with extensive investments in AI—could weigh heavily on its bottom line. Amazon’s strong quarter and Q3 sales guidance help dispel some fears about the health of the consumer. But its decision to once again offer an unusually broad profit range for the next quarter shows considerable uncertainty about the impact the Trump administration’s trade policies will have on retailers’ costs.

The insight: Amazon’s decision to double the length of its Prime Day sale delivered significant rewards for its advertising business—as we said it would. The takeaway: The first four-day Prime Day was an important learning experience for brands. With the event unlikely to get any shorter, sellers will need to be more precise about their ad strategy—focusing spending on times of day when shoppers are more likely to buy, or saving the bulk of their budgets for end-of-sale urgency.

The Trade Desk will join the S&P 500 on July 18, a milestone that highlights the company’s growing importance in the ad tech space. TTD has recently introduced tools like Deal Desk and AI-powered video placements via Kokai and Rembrand, all while vocally criticizing Amazon’s bundling practices. Despite a 30% YTD decline in stock price, the company’s Q1 revenue rose 25%, and retention remained above 95%. With Ventura OS on the horizon and renewed leadership in place, TTD is positioning itself as a transparent, open-web alternative to Big Tech’s walled gardens—just as it prepares to enter a new phase of institutional visibility.

The results: Amazon’s first four-day Prime Day event helped push US ecommerce sales to $24.1 billion from July 8–11—a 30.3% YoY increase, according to Adobe Digital Insights. Our take: Prime Day has cemented its place as a mid-summer shopping tentpole—and not just for Amazon. Other retailers, ranging from Dollar General to Walmart, leaned into the promotional window, turning July into a new retail battleground. Beyond sales, the event is a massive advertising opportunity. One of the under-the-radar reasons Amazon doubled the event’s length was to provide more ad inventory. Stretching Prime Day to four days gave brands more time to reach high-intent shoppers—and Amazon more room to expand its already-massive high-margin retail media business.

Social network ad spending will continue to lag behind search ad spending. But it will retain a firm grip on the title of second-largest digital ad spending channel through the remainder of our forecast period. We expect that social network ad spending in the US will exceed $100 billion in 2025, one year earlier than previously estimated.

The news: Google’s search dominance is slipping as AI innovations threaten its ad business. Its global web visits declined 1% YoY in April, according to Similarweb data published by AdWeek, compared with 182% growth for OpenAI’s ChatGPT and 181% for Perplexity. Google’s searches on Safari also dropped for the first time ever in April. In March, about 77% of all Google searches that triggered an AI Overview garnered zero clicks, which could dissuade advertisers from spending on the platform. Our take: As AI transforms search and keywords become less important, publishers and brands may need to rethink strategies for how their content is discovered and how they attract search users. AI-optimized content will likely become the next battleground for visibility and performance.

The news: Amazon’s Private Auction is quietly reshaping the CTV landscape by introducing more flexible buying on Prime Video. The format allows smaller advertisers and performance marketers to compete for inventory through open bidding, bypassing the need for costly guaranteed placements. As CPMs decline and the demand for agility rises, this move gives brands better control over pricing and access. Our take: While big brands may still favor premium guarantees, Amazon’s shift reflects broader momentum toward programmatic efficiency. By inviting direct-response buyers into the Prime Video ecosystem, Amazon is not just monetizing scale—it’s redefining what CTV access looks like in 2025.

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.
