StockStory’s Take

Reddit delivered quarterly results that exceeded Wall Street’s expectations, with the market responding positively to broad-based revenue growth and improving profitability. Management attributed the outperformance to ongoing investments in machine learning-driven ad formats and product enhancements, particularly around user onboarding and search integration. CEO Steven Huffman emphasized that “streamlining onboarding does improve retention,” and credited improved feed relevancy and search capabilities for driving user engagement and monetization. COO Jennifer Wong highlighted that the advertising business saw substantial gains across all verticals, with performance ads and shopping formats contributing meaningfully to growth.

Looking ahead, Reddit’s guidance reflects confidence in scaling automation and personalization initiatives designed to expand advertiser adoption and boost engagement. Management pointed to advancements in AI-powered ad tools, such as Reddit Max, and ongoing enhancements to the shopping ad ecosystem as key levers for sustaining revenue momentum. CFO Andrew Vollero noted the company’s focus on deploying capital efficiently, balancing continued investment in core business, M&A opportunities, and a newly authorized $1 billion share repurchase program. CEO Steven Huffman added, “Making Reddit faster, more relevant, and more accessible to everyone, everywhere, is our top priority as we execute our 2026 roadmap.”

Key Insights from Management’s Remarks

Management attributed the quarter’s results to the successful rollout of AI-powered ad formats, improvements in user product experience, and broader advertiser adoption across verticals and geographies.

• Ad funnel optimization: Reddit’s machine learning investments led to significant growth in both mid-funnel and lower-funnel ad conversions, with click volume up over 60% and conversion volume doubling year over year. Enhanced ad formats, such as dynamic product ads (DPAs), contributed to greater advertiser ROI, especially during peak shopping periods like Black Friday and Cyber Monday.
• Advertiser base expansion: The company reported a 75% increase in active advertisers, fueled by automation initiatives and new tools that simplify onboarding. COO Jennifer Wong stated that Reddit Max, an AI-powered campaign platform, delivered measurable reductions in advertiser costs and increased conversion rates, making it especially attractive to small and midsize businesses.
• Geographic and vertical growth: International revenues outpaced domestic, growing 78% year over year, with U.S. revenue up 68%. Eleven of Reddit’s top 15 industry verticals experienced revenue growth of at least 50%, led by retail, pharma, financial services, and technology. This diversification reduced reliance on any single segment or region.
• Product innovation and search integration: Reddit unified its core search and AI-powered Reddit Answers, driving weekly search users from 60 million to 80 million year over year. The launch of verified profiles for brands and individuals sought to preserve authenticity and transparency, a priority as generative AI content proliferates.
• Leadership and capital allocation: The appointment of Maria Angella Dew Smith as chief product officer was highlighted as a catalyst for faster innovation. Reddit also announced a $1 billion share repurchase program, with management reiterating that capital allocation priorities remain focused on core investment, selective M&A, and opportunistic buybacks.

Drivers of Future Performance

Reddit’s forward guidance is underpinned by plans to scale automation, deepen AI-driven ad optimization, and expand its advertiser ecosystem while navigating evolving engagement and content trends.

• AI and automation expansion: Management intends to broaden adoption of Reddit Max and related automation tools, aiming to streamline campaign creation and optimization for advertisers of all sizes. These efforts are expected to support both revenue growth and operational efficiency as more advertisers leverage Reddit’s community data for targeting.
• Deeper product and search integration: The company plans further investment in personalizing user experiences through AI and machine learning, particularly in onboarding flows and feed relevance. Management believes these improvements will translate to higher retention, increased engagement, and greater monetization opportunities, especially as search and shopping ad formats mature.
• Capital deployment and risk management: Reddit will balance investment in its core platform with potential M&A focused on technology and capability tuck-ins. Management acknowledged that while automation and engagement initiatives show momentum, the evolving landscape around AI-generated content and changing user behaviors presents ongoing operational and reputational risks.
