Reddit or Alphabet — Which of these Digital Advertising stocks has the greater upside potential? Let’s find out.
The Case for RDDT Stock
Reddit is benefiting from strong demand in its advertising business, which has become a key growth driver of the company’s impressive financial performance and future growth prospects. In the first quarter of 2026, Reddit reported total revenues of $663 million, up 69% year over year, with advertising revenues growing even faster at 74% to $625 million. This marks Reddit’s seventh consecutive quarter of revenue growth of more than 60%, underscoring the sustained momentum in its ad business.
Growth can be attributed to the company’s expanding portfolio, strong user engagement, including rising daily and weekly active users, gains in Average Revenue Per User and the expansion of advertiser tools such as Dynamic Product Ads (DPAs), Reddit Pixel and CAPI.
In the first quarter of 2026, DPAs have also driven more than 90% higher return on ad spend year over year, with brands like Liquid I.V. seeing DPAs outperform other campaigns by 40%. These advancements are attracting a broader range of advertisers. In the first quarter of 2026, active advertisers grew more than 75% year over year.
Reddit’s investments in artificial intelligence (AI)-powered tools remain noteworthy. The launch and adoption of Reddit Max, an automated, AI-powered campaign tool, enabled advertisers to achieve a 17% reduction in cost per action and a 25% increase in conversion rate in the first quarter of 2026. About 50% of Max campaign advertisers now use AI-powered creative features, and brands like Cozy have reported a 35% higher ROAS and a 28% lower cost per acquisition with these tools.
The Case for GOOGL Stock
Alphabet’s leadership in AI and strong partnerships with major retailers and tech companies position the company for continued growth and further upside in the digital advertising market. In the first quarter of 2026, Google’s advertising revenues increased 15.5% year over year to $77.25 billion and accounted for 70.3% of total revenues.
A key driver behind this surge is Alphabet’s aggressive integration of advanced AI models, particularly Gemini, across its entire ads infrastructure. These AI enhancements have significantly improved ad relevance and user intent understanding, allowing Alphabet to match ads more precisely to user queries, even for longer, more complex searches that were previously difficult to monetize.
In the first quarter of 2026, the company announced that Google Maps, with AI-driven improvements, has led to a nearly 10% increase in user engagement with promoted pins, while Smart Bidding powered by Gemini has enabled advertisers to achieve greater precision and performance.
Alphabet’s partnership with Walmart remains noteworthy. In June 2026, the company partnered with Walmart Connect to integrate Walmart’s first-party shopper audiences into Display & Video 360, starting with YouTube campaigns. Advertisers can now target high-intent Walmart shoppers and measure how video ads drive online and in-store sales through closed-loop measurement, improving campaign effectiveness and return on ad spend.
