Reddit's Ad Revenue Soars, But Stock Plummets
Reddit reported strong advertising growth for 2025, with Q4 ad revenue of $690 million (up 75% year‑over‑year) and total 2025 ad revenue of $2.1 billion (up 74% vs. 2024). The company said its ad business grew at least 60% each quarter of 2025 and active advertiser count rose 75% in Q4. Reddit highlighted engagement gains (121.4 million average daily active unique users, +19% YOY), performance improvements for lower‑funnel advertisers and product investments including Reddit Max optimization and an AI search product, Reddit Answers. Despite the results, Reddit’s stock dropped about 38% over the past month and recovered only modestly after hours. Management said it will stop differentiating logged‑in vs. logged‑out users in future reporting and emphasized full‑funnel ad capabilities and measurement investments as growth drivers.
Major social platform reported robust ad revenue growth and product investments (optimization, AI search) while crossing $2B annual ad revenue — a material signal for ad inventory, measurement trends and advertiser demand despite stock volatility.
