Reddit posted a standout Q2 2025, with revenues jumping 78% year-over-year to $500 million—including $465 million in ad revenue, up 84%. Net income reached $89 million with strong EBITDA and free cash flow. Global DAUs grew 21% to 110.4 million, and US ARPU climbed 59% to $7.87, signaling improved monetization. Reddit is now a billion-dollar US ad business a year ahead of forecasts, driven by growth in AI ad tools. Yet challenges remain: Reddit still holds only 1.1% of US social ad spend and relies heavily on Google Search traffic. Sustaining growth means reshaping advertiser perception and boosting direct engagement.
